Mental disorders in general hospital patients

Two major epidemiological studies using standardized instruments for diagnosis have revealed that the prevalence of mental disorders in general hospital inpatients range from 41.3% to 46.5%. The most prevalent groups of psychiatric disorders among general hospital inpatients are organic mental illness, depressive disorders, and alcohol dependence or abuse. The prevalence rates of organic brain syndromes, adjustment disorders with depressed mood, and alcohol dependence in general hospital inpatients are above those of the general population. In nearly half of the studied general hospital inpatients receiving a psychiatric diagnosis Consultation-Liaison (C-L) psychiatry interventions were found to be necessary. However, psychiatric consultation rates found in most recently presented studies in Germany and Austria range from 2.66% to 3.30%, and remain low when compared to the reported prevalence figures of psychiatric disorders and the demonstrated necessity for specific therapeutic interventions among general hospital inpatients. There is also evidence stemming from newly presented C-L follow-up studies that the remarkable advances in intensive care treatment, organ transplantation medicine and cardiac surgery with cardiopulmonary bypass within the past decade have an important impact on the general hospital inpatients; psychosocial outcome. One follow-up study of long-term acute respiratory distress syndrome (ARDS) survivors using the Structural Clinical Interview for the DSM-IV (SCID) has shown that 43.5% of these patients met the criteria for a full posttraumatic stress disorder (PTSD), 8.9% of these patients for a subthreshold or partial PTSD (sub-PTSD) at hospital discharge, and 23.9% of them still suffered from full PTSD, 17.8% of them from sub-PTSD. ARDS-Patients with PTSD symptomatology exhibited major impairments in a variety of dimensions of health-related quality of life. Another outcome study examining concurrently psychiatric morbidity and quality of life in intermediate-term survivors of orthotopic liver transplantation (OLT) survivors has documented that 5.4% of these patients had a full PTSD, and 17.3% of them a sub-PTSD at 4 year-follow-up. OLT- related PTSD symptomatology was associated with maximal decrements in health-related quality of life. The duration of intensive care treatment, the number of medical complications, and the occurrence of acute rejection were positively correlated with the risk of PTSD symptoms subsequent to OLT. Finally, one prospective 1-year outcome study has focused on psychiatric morbidity including postoperative delirium in patients who had undergone cardiac surgery employing cardiopulmonary bypass. Postoperative delirium developed in 32.4% of these patients, however, only in 5.9% of them severe delirium was noted. Short-term consequences of cardiac surgery included adjustment disorders with depressed features (32.4%), acute full in-hospital PTSD (17.6%), and in-hospital major depression (17.6%). The diagnostic status of in-hospital PTSD was linked to postoperative delirium. At 12 months, the severity of depression and anxiety disorders including PTSD improved and returned to the preoperative level. However, patients who were found to have major depression or PTSD before discharge, C-L psychiatric consultations were conducted. In conclusion, PTSD symptoms following medical illness and treatment are not rare. If they are untreated, PTSD symptoms such as intrusive recollections, avoidance and hyper-arousal may impair the patients; quality of life more than the primary disease. This seems to be also true for a subthreshold PTSD. To adequately diagnose and treat patients at risk of developing PTSD, close collaboration between physicians of all subspecialties and C-L psychiatrists will be necessary.     

Change in accuracy of recognizing psychiatric disorders by non-psychiatric physicians: five-year data from a psychiatric consultation-liaison service

Aim: Psychiatric disorders are easily underestimated and under‐recognized by physicians. The aim of the present study was to investigate the change in accuracy of recognizing psychiatric symptoms. Methods: Consecutive 5‐year consultation–liaison data were collected and patients with one of the five common psychiatric diagnoses, including depressive disorders, substance use disorders, delirium, anxiety disorders and psychotic disorders, were chosen for analysis. The primary care physician's initial impression of a psychiatric diagnosis was recorded based on their reason for referral on the referral sheets. Accurate recognition was defined as matching of the physician's initial impression with the psychiatrist's final diagnosis. Mentioning the core symptoms of psychiatric diagnostic criteria or common synonyms would be considered as correct recognition. Results: The overall accuracy of recognition was 41.5% and there was no significant change during this 5‐year period. Substance use disorders were the one diagnosis with the highest agreement, followed by delirium, depressive disorders, anxiety disorders, and psychotic disorders. As for the factors associated with accurate recognition, male patients or those with multiple physical illnesses were more likely to have their psychiatric symptoms recognized correctly. Conclusions: Without comprehensive postgraduate psychiatric education, the accuracy of recognizing psychiatric symptoms does not improve year by year. Education should focus on common psychiatric problems among medical inpatients, especially those easily misdiagnosed, such as depression and delirium.     

The prevalence of depression and anxiety disorders in indigenous people of the Americas: A systematic review and meta-analysis

Indigenous populations are considered at higher risk of psychiatric disorder but many studies do not include direct comparisons with similar non-Indigenous controls. We undertook a meta-analysis of studies that compared the prevalence of depression and anxiety disorders in Indigenous populations in the Americas with those of non-Indigenous groups with similar socio-demographic features (Registration number: CRD42015025854). A systematic search of PubMed, Medline, PsycInfo, PsycArticles, ScienceDirect, EMBASE, and article bibliographies was performed. We included comparisons of lifetime rates and prevalence of up to 12 months. We found 19 studies (n = 250, 959) from Latin America, Canada and the US. There were no differences between Indigenous and similar non-Indigenous groups in the 12-month prevalence of depressive, generalised anxiety and panic disorders. However, Indigenous people were at greater risk of PTSD. For lifetime prevalence, rates of generalised anxiety, panic and all the depressive disorders were significantly lower in Indigenous participants, whilst PTSD (on adjusted analyses) and social phobia were significantly higher. Results were similar for sub-analyses of Latin America, Canada and the US, and sensitivity analyses by study quality or setting (e.g. health, community etc.). Risk factors for psychiatric illness may therefore be a complex interaction of biological, educational, economic and socio-cultural factors that may vary between disorders. Accordingly, interventions should reflect that the association between disadvantage and psychiatric illness is rarely due to one factor. However, it is also possible that assessment tools don't accurately measure psychiatric symptoms in Indigenous populations and that further cross-cultural validation of diagnostic instruments may be needed too.     

Psychopathological sequelae of the 11 March terrorist attacks in Madrid

Objective To describe the prevalence and correlates of post-traumatic stress disorder (PTSD), depressive and anxiety disorders, or any other mental disorder among adult victims treated in a hospital at different points in time after the 11 March 2004 terrorist attacks in Madrid. Design, Setting, and Participants A random sample of 56 individuals injured in the attacks was interviewed in person at one, six, and twelve months after the attacks. Main Outcome Measures Current DSM-IV mental disorders: depressive disorders and anxiety disorders (PTSD, generalised anxiety, agoraphobia, social phobia, and panic disorder) were assessed with the Spanish version of the MINI (Mini International Neuropsychiatric Interview), a structured, lay-administered psychiatric interview. Results PTSD was the most prevalent psychiatric disorder (35.7% at month 1, 34.1% at month 6, and 28.6% at month 12), followed by major depression (28.6%, 22.7%, and 28.6%, respectively). Others relevant conditions were suicide risk, generalised anxiety disorder (GAD), agoraphobia, and panic disorder. No significant differences in the prevalence of the disorders were found between the different assessment times. Patients with a psychiatric history prior to 11 March had a higher prevalence of PTSD, major depression, GAD, and panic disorder at month 1. Females had higher prevalence of PTSD, agoraphobia, and panic disorder at month 1. The only predictive factor for PTSD at month 12 was PTSD at month 6 (OR = 14.007). The only predictive factor for major depression at month 12 was major depression at month 6 (OR = 15.847). Conclusion The prevalence of PTSD and major depression was high and remained stable between month 1, month 6, and month 12. The only predictive factor for PTSD at month 12 was PTSD at month 6.     

Fatigue,psychological and cognitive impairment following transient ischaemic attack and minor stroke: a systematic review

Transient ischaemic attack (TIA) and minor stroke are characterized by short‐lasting symptoms; however, anecdotal and empirical evidence suggests that these patients experience ongoing cognitive/psychological impairment for which they are not routinely treated. The aims were (i) to investigate the prevalence and time course of fatigue, anxiety, depression, post‐traumatic stress disorder(PTSD) and cognitive impairment following TIA/minor stroke; (ii) to explore the impact on quality of life (QoL), change in emotions and return to work; and (iii) to identify where further research is required and potentially inform an intervention study. A systematic review of MEDLINE, EMBASE, PSYCINFO, CINAHL, the Cochrane libraries and the grey literature between January 1993 and April 2013 was undertaken. Literature was screened and data were extracted by two independent reviewers. Studies were included of adult TIA/minor stroke participants with any of the outcomes of interest: fatigue, anxiety, depression, PTSD, cognitive impairment, QoL, change in emotions and return to work. Random‐effects meta‐analysis pooled outcomes by measurement tool. Searches identified 5976 records, 289 were assessed for eligibility and 31 studies were included. Results suggest high levels of cognitive impairment and depression post‐TIA/minor stroke which decreased over time. However, frequencies varied between studies. Limited information was available on anxiety, PTSD and fatigue. Meta‐analysis revealed that the measurement tool administered influenced the prevalence of cognitive impairment: Mini‐Mental State Examination 17% [95% confidence interval (CI) 7, 26]; neuropsychological test battery 39% (95% CI 28, 50); Montreal Cognitive Assessment 54% (95% CI 43, 66). There is evidence to suggest that TIA/minor stroke patients may experience residual impairments; however, results should be interpreted with caution because of the few high quality studies. Notwithstanding, it is important to raise awareness of potential subtle but meaningful residual impairments.     

The Prevalence of Migraine Headaches in an Anxiety Disorders Clinic Sample

The association between migraine and psychiatric disorders has been reported in both clinical and epidemiological studies. The prevalence of psychiatric disorders has been found to be increased among individuals with migraine. Studies assessing migraine in psychiatric patients are limited and the majority of these studies have focused solely on examining patients with major depression. In the present study, we examined the prevalence and characteristics of migraine headache in an anxiety disorders clinic sample in order to better understand the relationship between these commonly associated conditions. We evaluated 206 consecutive outpatients to an Anxiety Disorders Clinic for the prevalence of migraine. The presence of migraine was established using International Headache Society Criteria. Subjects completed a modified self‐report version of the Headache Diagnostic Questionnaire. In order to assess the relationship between migraine and anxiety disorder symptom severity, subjects completed standardized measures of symptom severity. The prevalence of migraine in our anxiety disorder clinic sample was 67%. Anxiety disorder patients with migraine presented with a significantly greater number of comorbid psychiatric disorders than patients without migraine (P= 0.012). The prevalence of migraine was significantly higher in patients with a diagnosis of either panic disorder with agoraphobia (P= 0.048) or major depressive disorder/dysthymia (P= 0.008) compared to other psychiatric disorders. The severity of anxiety disorder symptoms was significantly higher in patients with migraine compared to patients without migraine. This study suggests that there is an increased prevalence of migraine headaches among anxiety disorder patients as compared to the general population. Migraine comorbidity may have important clinical implications, such that the treatment of one condition could potentially ameliorate the development or progression of the other. Further research is required to better understand the nature and implications of the association between migraine and psychiatric disorders.     

On the threshold of disorder: a study of the impact of the DSM-IV clinical significance criterion on diagnosing depressive and anxiety disorders in clinical practice

BACKGROUND: Two recent reanalyses of epidemiologic studies found that adding a clinical significance criterion reduced disorder prevalence. Patients presenting for clinical care are usually distressed or impaired by their symptoms; thus, the DSM-IV clinical significance criterion might have little impact on diagnosis in clinical practice. In the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project, we examine the impact of the DSM-IV clinical significance criterion on diagnostic frequencies of depressive and anxiety disorders in psychiatric outpatients. METHOD: 1500 psychiatric outpatients were evaluated with the Structured Clinical Interview for DSM-IV. We determined the percentage of patients who met symptom criteria but did not meet the DSM-IV clinical significance criterion for major depressive disorder, posttraumatic stress disorder (PTSD), generalized anxiety disorder (GAD), social phobia, specific phobia, panic disorder, and obsessive-compulsive disorder. RESULTS: No patient who met the symptom criteria for current major depressive disorder or PTSD failed to meet the clinical significance criterion. Less than 2% of patients meeting the symptom criteria for current GAD did not meet the clinical significance criterion. There was variability among the remaining anxiety disorders in the percentage of symptomatic patients who met the clinical significance criterion. CONCLUSION: In psychiatric patients, the clinical significance criterion had little impact on diagnosing major depressive disorder, GAD, and PTSD, disorders that are defined, in part, by disruptions of daily regulatory domains such as sleep, appetite, energy, and concentration. In contrast, the clinical significance criterion had a greater impact in determining whether phobic fears, obsessive thoughts, and panic attacks were sufficiently distressing or impairing to qualify for disorder status.     

Pharmacogenomics and therapeutic prospects in dementia

OBJECTIVE: To describe the prevalence and correlates of post-traumatic stress disorder (PTSD), depressive and anxiety disorders, or any other mental disorder among adult victims treated in a hospital at different points in time after the 11 March 2004 terrorist attacks in Madrid. DESIGN, SETTING, AND PARTICIPANTS: A random sample of 56 individuals injured in the attacks was interviewed in person at one, six, and twelve months after the attacks. MAIN OUTCOME MEASURES: Current DSM-IV mental disorders: depressive disorders and anxiety disorders (PTSD, generalised anxiety, agoraphobia, social phobia, and panic disorder) were assessed with the Spanish version of the MINI (Mini International Neuropsychiatric Interview), a structured, lay-administered psychiatric interview. RESULTS: PTSD was the most prevalent psychiatric disorder (35.7% at month 1, 34.1% at month 6, and 28.6% at month 12), followed by major depression (28.6%, 22.7%, and 28.6%, respectively). Others relevant conditions were suicide risk, generalised anxiety disorder (GAD), agoraphobia, and panic disorder. No significant differences in the prevalence of the disorders were found between the different assessment times. Patients with a psychiatric history prior to 11 March had a higher prevalence of PTSD, major depression, GAD, and panic disorder at month 1. Females had higher prevalence of PTSD, agoraphobia, and panic disorder at month 1. The only predictive factor for PTSD at month 12 was PTSD at month 6 (OR = 14.007). The only predictive factor for major depression at month 12 was major depression at month 6 (OR = 15.847). CONCLUSION: The prevalence of PTSD and major depression was high and remained stable between month 1, month 6, and month 12. The only predictive factor for PTSD at month 12 was PTSD at month 6.     

Psychiatric comorbidity in a population of Parkinson''s disease patients

Behavioural disturbances are frequently observed in Parkinson's disease (PD), including mood and anxiety disorders. The existence of a comorbidity between such psychiatric disorders in PD patients has been suggested only in a few studies. To assess the prevalence of mood and anxiety disturbances, and the rate of comorbidity of such disorders in PD. Secondary aim was to correlate the prevalence of psychiatric disorders in PD with age, sex, laterality of motor symptomatology, clinical features, severity of disease, age of onset and PD duration, and anti-parkinsonian therapy. Ninety consecutive PD outpatients, and 90 age- and sex-matched controls were included. All PD patients enrolled were non-fluctuating (21 de novo, 69 treated with levodopa or dopamine agonists). PD patients and controls with Mini Mental State Examination score <23 were excluded. Psychiatric diagnosis was performed by semistructured interview according with DSM-IV criteria and the severity of depressive and anxious symptoms was rated with clinical rating scales. Major depression was found in 21.1% PD patients vs. 3.3% controls (P < 0.01, chi-square analysis), dystimia in 18.8% PD patients vs. 4.4% controls (P < 0.05), panic disorders in 30% PD patients vs. 5.5% controls (P < 0.01). No difference in the prevalence of other anxiety disorders was observed between the two groups. The comorbidity of mood and anxiety disorders was found in 19.3% PD patients vs. 8.6% controls (P < 0.01). No correlation was reported between the prevalence of behavioural disturbances and any of the demographic, clinical or pharmacological data taken into account. Our findings might suggest the existence of a wide spectrum of psychiatric disorders in PD ranging from pure depressive disorders, comorbid depressive and anxiety disorders, and pure anxiety disorders, presumably linked to the same neurobiological substrate.     

Characterization of depression in war-related posttraumatic stress disorder

OBJECTIVE: Many patients with posttraumatic stress disorder (PTSD) have symptoms of depression, but operationalized psychological constructs related to depression have not been used extensively in characterizing affective symptoms of PTSD. The authors' objective is to better characterize the affective component of PTSD. METHOD: The subjects were 45 male psychiatric inpatients at a Veterans Administration medical center; 28 met DSM-III-R criteria for PTSD and 17 met Research Diagnostic Criteria (RDC) for major depressive disorder. All of the subjects with PTSD were Vietnam veterans. The 21-item Hamilton Rating Scale for Depression was used to assess state measures of symptom severity, and the Depressive Experiences Questionnaire was used to measure dimensions of dependency, self-criticism, and self-efficacy. RESULTS: The mean total Hamilton scale score of the patients with PTSD was nonsignificantly higher than that of the patients with major depressive disorder; patients with PTSD had higher scores on almost all individual Hamilton symptoms, particularly insomnia, somatic anxiety, and diurnal variation. Patients with PTSD had significantly higher scores on the self-criticism scale but not on the dependency and self-efficacy scales of the Depressive Experiences Questionnaire. The scores of patients with PTSD on the dependency and self-criticism scales were negatively correlated. No significant differences between patients with PTSD with and without concurrent major depressive disorder were observed. CONCLUSIONS: Characterization of such depressive dimensions of PTSD as dependency and self-criticism may have important clinical implications.     

Posttraumatic stress disorder and psychiatric comorbidity among detained youths

OBJECTIVE: This study examined the prevalence of posttraumatic stress disorder (PTSD) and comorbid psychiatric disorders among juvenile detainees. METHODS: The sample consisted of a stratified random sample of 898 youths aged ten to 18 years who were arrested and detained in Chicago. RESULTS: Among participants with PTSD, 93% had at least one comorbid psychiatric disorder; however, among those without PTSD, 64% had at least one comorbid psychiatric disorder. Over half (54%) of the participants with PTSD had two or more types of comorbid disorders--that is, affective, anxiety, behavioral, or substance use disorders--and 11% had all four types of comorbid disorders. Among males, having any psychiatric diagnosis significantly increased the odds of having comorbid PTSD. Among females, alcohol use disorder and both alcohol and drug use disorders significantly increased the odds of having PTSD. No significant difference in prevalence rates of PTSD was found between males and females with specific psychiatric disorders. The prevalence of any comorbid psychiatric disorder was significantly greater for males with PTSD than that for females with PTSD (OR=3.4, CI=1.1-10.6, p<.05). CONCLUSIONS: Detection of comorbid PTSD among detained youths must be improved. PTSD is often missed because traumatic experiences are rarely included in standard screens or volunteered by patients. When planning treatment, clinicians must consider ramifications of comorbid PTSD.     

Systematic Literature Review of Psychiatric Comorbidities in Adults with Epilepsy

Background and PurposeMental illness is disproportionately common in people with epilepsy (PWE). This systematic literature review identified original research articles that reported the prevalence of psychiatric comorbidities based upon clinical assessments in a sample of PWE and assessed the clinical features of the populations found in studies included in our review of mental health comorbidity.MethodsThe included articles were written in English and published from 2008 to 2018, and focused on adults aged ≥18 years who had psychiatric diagnoses determined in clinical assessments, such as those found in medical records, clinician psychiatric evaluations, structured diagnostic interviews, and mental health screening questionnaires specific for a psychiatric disorder. The primary outcome was the prevalence of psychiatric comorbidities as a percentage of the total sample of PWE. Additional data included the overall sample size, mean age, epilepsy type, study design, and method of diagnosis. A modified Newcastle Ottawa Scale was used to assess the quality of the studies. All 23 articles that were consistent with the inclusion criteria were related to observational studies.ResultsMood disorders and anxiety disorders were the most common psychiatric comorbidities, with prevalence rates of 35.0% and 25.6%, respectively. Major depressive disorder was the most common mood disorder, with a prevalence of 24.2%. Post-traumatic stress disorder (PTSD) had the highest reported prevalence among anxiety disorders, at 14.2%, followed by general anxiety disorder at 11.1%. Other comorbidities included psychosis (5.7%), obsessivecompulsive disorder (3.8%), schizophrenia (1.7%), bipolar disorder (6.2%), and substance abuse (7.9%). The pooled prevalence of suicidality, as reported for two studies, was 9.3%. Temporal lobe epilepsy (TLE) was associated with higher levels of psychiatric comorbidity. Two (8.7%) of the 23 studies compared psychiatric comorbidities in TLE with that of extratemporal lobe epilepsy (ETLE), and one of these two studies found that depression was more common in TLE (53.8%) than in ETLE (25%). Regarding seizure types, partial seizures were associated with a higher prevalence of depression vs generalized seizures.ConclusionsThis systematic literature review of recent original research found a relatively high prevalence of mental health comorbidities in PWE. Mood and anxiety disorders are the most common comorbidities, while psychotic spectrum conditions such as schizophrenia and bipolar disorder are much rarer. The prevalence of comorbidity may vary with the epilepsy type and treatment responsiveness. These findings suggest that screening tools for depression and anxiety should be included as part of the training for epilepsy care, while resources for other relatively common conditions such as PTSD and substance abuse disorders should be readily available to neurology specialists who treat PWE.     

Prevalence of depression and anxiety in hospitalized chronic obstructive pulmonary disease patients and their quality of life: a pilot study

Introduction: There is a high prevalence of psychiatric comorbidities in patients with Chronic Obstructive Pulmonary Disease (COPD). It has been reported that if left untreated, the psychiatric comobidities can lead to poorer quality of life. The present study was initiated to investigate the prevalence of major depressive disorder, generalized anxiety disorder and panic disorder in hospitalized COPD patients and their quality of life. Methods: The Patient Health Questionnaire (PHQ) of the Primary Care Evaluation of Mental Disorders (PRIME‐MD) was administered to screen an opportunistic sample of COPD patients admitted to a general hospital for the abovementioned psychiatric disorders. The Medical Outcomes Study (MOS) 36‐Item Short Form Health Survey (SF‐36) was utilized to assess quality of life. Results: Fifty‐one patients were analyzed. The prevalence of major depressive disorder in this sample on screening was 7.8% (95% CI 2.2–18.9) and that of anxiety disorders (generalized anxiety disorder and panic disorder) was 5.9% (95% CI 1.2–16.2). The quality of life of COPD patients with psychiatric comorbidities in the present study was severely impaired in seven of the eight domains measured by the SF‐36. Discussion: Despite the small sample size of COPD patients, the prevalence of psychiatric comorbidities was not insignificant. The present study showed that the quality of life of hospitalized COPD patients with psychiatric illnesses was significantly lowered. Treatment of COPD should include addressing psychosocial issues.     

Psychiatric and neuropsychiatric sequelae of COVID-19 – A systematic review

It has become evident that coronavirus disease 2019 (COVID-19) has a multi-organ pathology that includes the brain and nervous system. Several studies have also reported acute psychiatric symptoms in COVID-19 patients. An increasing number of studies are suggesting that psychiatric deficits may persist after recovery from the primary infection. In the current systematic review, we provide an overview of the available evidence and supply information on potential risk factors and underlying biological mechanisms behind such psychiatric sequelae.We performed a systematic search for psychiatric sequelae in COVID-19 patients using the databases PubMed and Embase. Included primary studies all contained information on the follow-up period and provided quantitative measures of mental health. The search was performed on June 4th 2021.1725 unique studies were identified. Of these, 66 met the inclusion criteria and were included. Time to follow-up ranged from immediately after hospital discharge up to 7 months after discharge, and the number of participants spanned 3 to 266,586 participants. Forty studies reported anxiety and/or depression, 20 studies reported symptoms- or diagnoses of post-traumatic stress disorder (PTSD), 27 studies reported cognitive deficits, 32 articles found fatigue at follow-up, and sleep disturbances were found in 23 studies. Highlighted risk factors were disease severity, duration of symptoms, and female sex. One study showed brain abnormalities correlating with cognitive deficits, and several studies reported inflammatory markers to correlate with symptoms. Overall, the results from this review suggest that survivors of COVID-19 are at risk of psychiatric sequelae but that symptoms generally improve over time.     

Household survey of psychiatric morbidity in Cambodia

AIMS: To estimate the prevalence of psychiatric symptoms in the Kampong Cham province and to determine the association between these symptoms and an impaired social functioning. METHODS: Cross-sectional cluster sample survey conducted among adults randomly selected within 50 clusters distributed over the province. METHODS: Of the respondents, 42.4% reported symptoms that met the Diagnostic and Statistical Manual of Mental Disorders, 4th edition criteria for depression, 53% displayed high anxiety symptoms and 7.3% met posttraumatic stress disorder (PTSD) criteria. Posttraumatic symptoms of intrusion and avoidance were present in 47.8% and 45.4% respectively. When reviewing comorbidities, 29.2% had depression and anxiety symptoms, 16.5% anxiety symptoms, 6.1% depression and 7.1% had triple comorbidity (PTSD, depression and anxiety). Regarding social functioning, 25.3% reported being socially impaired. Respondents with comorbid symptoms for depression, anxiety and PTSD were associated with an increased risk for social impairment compared with others. Being over 65 years and having experienced violent events were other factors associated with social impairment. CONCLUSION: Five years after the return of a more stable context in Cambodia, the prevalence of psychiatric symptoms in the community remains high. In addition, these symptoms are strongly associated with social impairment. This suggests that beyond psychosocial programs, the implementation of adapted clinical psychiatric care should be considered as a priority.     

A systematic review of prevalence studies of depression in Parkinson's disease

Prevalence rates of depressive disorders in Parkinson's disease (PD) vary widely across studies, ranging from 2.7% to more than 90%. The aim of this systematic review was to calculate average prevalences of depressive disorders taking into account the different settings and different diagnostic approaches of studies. Using Medline on Pubmed, a systematic literature search was carried out for studies of depression in Parkinson's disease. A total of 104 articles were included and assessed for quality; 51 articles fulfilled the quality criteria. Multiple publications from the same database were not included in the meta‐analysis. In the remaining 36 articles, the weighted prevalence of major depressive disorder was 17% of PD patients, that of minor depression 22% and dysthymia 13%. Clinically significant depressive symptoms, irrespective of the presence of a DSM defined depressive disorder, were present in 35%. In studies using a (semi) structured interview to establish DSM criteria, the reported prevalence of major depressive disorder was 19%, while in studies using DSM criteria without a structured interview, the reported prevalence of major depressive disorder was 7%. Population studies report lower prevalence rates for both major depressive disorder and the clinically significant depressive symptoms than studies in other settings. This systematic review suggests that the average prevalence of major depressive disorder in PD is substantial, but lower than generally assumed. © 2007 Movement Disorder Society     

Comorbidity of psychiatric disorders and personality profiles of American World War II prisoners of war

To characterize the effects of trauma sustained more than 40 years ago, prevalence of psychiatric disorders and personality dimensions were examined in a sample of 62 former World War II POWs. The negative effects of their experiences are reflected in their multiple lifetime diagnoses and in their current personality profiles. Fifty percent met DSM-III posttraumatic stress disorder (PTSD) criteria within 1 year of release; 18 (29%) continued to meet the criteria 40 years later at examination (chronic PTSD). A lifetime diagnosis of generalized anxiety disorder was found for over half the entire sample; in 42% of those who never had PTSD, 38% of those with recovery from PTSD, and 94% of those with chronic PTSD. Ten percent of those without a PTSD diagnosis had experienced a depressive disorder, as had 23% of those with recovery from PTSD and 61% of the POWs with chronic PTSD. The combination of depressive and anxiety disorders also was frequent in the total sample (61%). Current MMPIs of three groups with psychiatric diagnosis were compared with those of POWs who had no diagnoses and with a group of Minnesota normal men. Profile elevations for the groups, from highest to lowest, were: POWs with chronic PTSD, POWs with recovery from PTSD, POWs with other psychiatric diagnoses, POWs with no disorders, and Minnesota normal men. Symptoms of anxiety, depression, and somatic concerns combined with the personality styles of suppression and denial characterize the current adjustment of negatively affected POWs.     

Predictors and outcomes of delirium

OBJECTIVES: To determine factors associated with the occurrence of delirium among patients undergoing surgical repair of abdominal aortic aneurysm (AAA). METHODS: The sample included all consenting patients who underwent AAA repair during a 12-month period. Before surgery, daily while in hospital, and at 1 and 6 months after surgery, we assessed patients' mood, mental status and functional status. We compared delirious and nondelirious patients for severity of preoperative depressive symptoms, length of hospital stay and mortality. The effects of delirium on postoperative functional status were assessed in conjunction with postoperative depressive symptoms using regression models. RESULTS: The sample of 35 patients was primarily male and elderly; one-quarter had three or more medical conditions; and eight (23%) developed delirium after surgery. Postoperative delirium was significantly associated with preoperative depressive symptoms, alcohol use and cognitive impairment as well as with longer lengths of stay and poorer functional status at 1 and 6 months after surgery. CONCLUSION: Identification and treatment of patients with depressive symptoms, alcohol use and cognitive impairment prior to AAA surgery could reduce the incidence of postoperative delirium and the prolonged hospital stays and impaired functional status associated with it. Surgeons should consider using simple screening instruments before surgery to identify patients at risk and referring them for psychiatric evaluation and treatment. They should also consider including psychiatrists early in the care of high-risk patients to improve detection of and early intervention for delirium.     

Post-traumatic stress disorder

BACKGROUND: The study is aimed at investigating the influence of trauma type, pre-existing psychiatric disorders with an onset before trauma, and gender on post-traumatic stress disorder (PTSD). METHODS: Traumas, PTSD and psychiatric disorders were assessed in a representative sample of 4075 adults aged 18-64 years using the Composite International Diagnostic Interview. Pre-existing DSM-IV diagnoses of anxiety disorders, depressive disorders, somatoform disorders, alcohol abuse and dependence, nicotine dependence, gender, and the type of trauma were analysed with logistic regressions to estimate the influence of these factors on the risk for developing PTSD. RESULTS: The lifetime prevalence of exposure to any trauma did not vary by gender. The conditional probability of PTSD after exposure to trauma was higher in women (11.1% SE = 1.58) than men (2.9% SE = 0.83). Univariate analyses showed that pre-existing anxiety disorders, somatoform disorders and depressive disorders significantly increase the risk of PTSD. Multivariate analyses revealed that specific types of trauma, especially rape and sexual abuse, pre-existing anxiety disorders and somatoform disorders are predictors of an increased risk of PTSD, while gender and depressive disorder were not found to be independent risk factors. CONCLUSION: Women do not have a higher vulnerability for PTSD in general. However, especially sexually motivated violence and pre-existing anxiety disorders are the main reasons for higher prevalences of PTSD in women.
