Vulnerability to psychosis in patients attending primary and psychiatric care. Results of the RADEP study

We studied occurrence of psychotic symptoms and their associations with occurrence of depressive and manic symptoms; 563 patients attending primary care (PrC) and 163 patients attending psychiatric outpatient care (PsC) completed a questionnaire including lists of psychotic, manic and depressive symptoms, and patients with depressive symptoms were interviewed using the same questionnaire 6 months after baseline examination. Of PrC patients, 8.5% and of PsC patients, 36.2% reported at least seven lifetime psychotic symptoms. During the 6-month follow-up, the corresponding figures were 0.22% for PrC and 2.84% for PsC patients. Among PrC patients, men, young, never-married, students and unemployed reported more psychotic symptoms than others. In multivariate analyses, occurrence of psychotic symptoms was associated with young age, never being married, poor functioning and former psychiatric treatment, as well as with occurrence of manic and depressive symptoms. Psychotic symptoms are rather prevalent in primary care and very common in psychiatric care. In primary care, vulnerability to psychosis is associated with the patient's background more strongly than in psychiatric care. Concurrent occurrence of psychotic symptoms with manic and depressive symptoms is common.     

Vulnerability to psychosis increases the risk of depression. Results of the RADEP study

We studied prevalence of depressive symptoms in primary care (PrC) and in psychiatric outpatient care (PsC), and how psychotic and manic symptoms are associated with current depressive symptoms. Altogether 563 patients attending PrC and 163 patients attending PsC filled in a questionnaire including the Depression Scale (DEPS), the Mood Disorder Questionnaire (MDQ) and questions on psychotic symptoms from the Composite International Diagnostic Interview (CIDI). Patients with depressive symptoms (DEPS score > 8) were interviewed by phone using the same checklist 6 months after baseline examination. From the PrC sample, 19.5% and from the PsC sample 73.0% were DEPS positive. In the PrC but not in the PsC sample, patients' background associated strongly with occurrence of depressive symptoms. Both at baseline and at follow-up, depressive symptoms correlated significantly with psychotic and manic symptoms. In multivariate analyses, when the effects of background, health and functioning were taken into account, baseline depressive symptoms associated significantly with lifetime psychotic symptoms. Depressive symptoms at follow-up associated significantly with psychotic symptoms during the follow-up period. In the PrC sample, this association was significant even when the effect of baseline depressive symptoms was controlled. About one-fifth of patients attending primary care and about three-quarters of patients attending psychiatric outpatient patient care suffer from depressive symptoms. Vulnerability to psychosis, indicated by occurrence of psychotic symptoms, increases the risk of and slower recovery from depressive symptoms in the patients attending primary care. Therefore, vulnerability to psychosis should be evaluated when treatment intervention for patients with depressive symptoms is planned.     

Psychotism and its dimensions in primary care. Associations with patient's background and manic and depressive symptoms. Results of the RADEP study

Dimensions of psychotism have mainly been studied in clinical samples. We studied psychotism, its dimensions and their associations, in a primary care sample. In all, 1199 primary care patients over 18 years of age filled in a questionnaire including lists of psychotic (the Composite International Diagnostic Interview, CIDI), depressive (the Depression Scale, DEPS) and manic (the Mood Disorder Questionnaire, MDQ) symptoms. Psychotic symptoms were factored, and variance in factor scores was explained by patients' background and by depressive and manic symptoms. In the principal component solution, the first factor explained 22% of the total variance in psychotic (CIDI) symptoms and was named global psychotism. Varimax rotation produced seven interpretable dimensions: Schneiderian (9.7% of variance), passivity (8.9%), hallucinatory (8.5%), paranoid (7.7%), infidelity (7.6%), somatic (7.6%) and reference experiences (5.9%). Together they explained 52% of the total variance of CIDI symptoms. Global psychotism (P=0.000), as well as hallucinatory (P=0.003), paranoid (P=0.000) and infidelity (P=0.000) experiences associated inversely with age. Otherwise, patients' background associated differently with global psychotism and with factor dimensions in CIDI symptoms. Manic symptoms associated with global psychotism and with all CIDI dimensions, whereas depressive symptoms associated with global psychotism, passivity, paranoid and infidelity experiences. Psychotism is composed of a global factor and of independent dimensions, and is more prevalent in young people. Independently of patients' background, manic widely and depressive symptoms less widely associate with occurrence of psychotism.     

Prevalence and description of psychotic features in bipolar mania

Psychotic symptoms are common in both the manic and depressive phases of bipolar disorder. More than half of patients with bipolar disorder will experience psychotic symptoms in their lifetime. Grandiose delusions are the most common type of psychotic symptom, but any kind of psychotic symptom, including thought disorder, hallucinations, mood-incongruent psychotic symptoms, and catatonia can present as part of a manic episode. Psychotic symptoms suggest poor prognosis when they occur in the absence of affective symptoms. However, psychotic symptoms can mask affective symptoms and make the distinction between manic-depressive illness and other psychiatric disorders difficult, especially in minorities. Careful assessment of prior psychiatric history, family history, and treatment response can aid in the differentiation of affective disorders with psychotic features from psychotic disorders.     

Diagnostic subtypes of bipolar disorder in older versus younger adults

OBJECTIVE: To investigate differences in diagnostic subtypes of bipolar disorder as according to ICD-10 between patients whose first contact with psychiatric health care occurs late in life (over 50 years of age) and patients who have first contact earlier in life (50 years of age or below). METHODS: From 1994 to 2002 all patients who received a diagnosis of a manic episode or bipolar disorder at initial contact with the mental healthcare system, whether outpatient or inpatient, were identified in Denmark's nationwide register. RESULTS: A total of 852 (49.6%) patients, who were over age 50, and 867 patients, who were 50 or below, received a diagnosis of a manic episode or bipolar disorder at the first contact ever. Older inpatients presented with psychotic symptoms (35.4%) significantly less than younger inpatients (42.6%) due specifically to a lower prevalence of manic episodes with psychotic symptoms. Conversely, older inpatients more often presented with severe depressive episodes with psychotic symptoms than younger inpatients (32.0% versus 17.0%). Among outpatients, no significant differences were found between patients older than 50 years and patients 50 years of age or younger. However, a bimodal distribution of age at first outpatient contact was found with an intermode of 65 years and outpatients older than 65 years more often presented with severe depressive episodes with psychosis. CONCLUSIONS: Bipolar patients who are older at first psychiatric hospitalization (>50 years) present less with psychotic manic episodes and more with severe depressive episodes with psychosis than younger patients. The distribution of age at first outpatient contact is bimodal with an intermode of 65 years and outpatients older than 65 years more often present with severe depressive episodes with psychosis.     

Childhood trauma and distress experiences associate with psychotic symptoms in patients attending primary and psychiatric outpatient care. Results of the RADEP study

GoalWe studied the prevalence of and association between psychotic symptoms and childhood trauma experiences in primary care patients compared with psychiatric care patients.Patients and methodsWe note 911 primary care and psychiatric care patients over 16 years of age filled in a questionnaire including a list of lifetime psychotic symptoms of the Composite International Diagnostic Interview (CIDI) and the childhood Trauma and Distress Scale (TADS). Prevalence of and correlations between psychotic symptoms and childhood trauma and stressful experiences were calculated. Association between the sum of CIDI symptoms and the TADS sum score was analysed by Anova.ResultsIn primary care, more than half of the patients had had at least one psychotic symptom during their lifetime, and nearly 70% of patients had experienced a childhood trauma at some time or more often. In psychiatric care patients, CIDI symptoms were more prevalent and TADS scores were higher than in primary care patients. In the whole sample, CIDI symptoms correlated with TADS scores. The association remained even when the effects of age, service, and patient's functioning were taken into account. There was a dose-response between TADS scores and CIDI symptoms.ConclusionChildhood trauma experiences associate with psychotic symptoms. In clinical work, it is important to acknowledge that psychotic symptoms and childhood trauma experiences are common not only in psychiatric care but also in primary care patients, and thus require adequate attention.     

Phenomenology associated with age at onset in patients with bipolar disorder at their first psychiatric hospitalization

OBJECTIVE: To compare the clinical presentation of patients with early-onset (age <18 years) and typical-onset (age 20-30 years) bipolar disorder at the time of first hospitalization. METHODS: Patients, aged 12-45 years at their first psychiatric hospitalization, with a DSM-IV diagnosis of bipolar disorder, manic or mixed, were evaluated on measures of manic, depressive, and positive psychotic symptoms. Differences in symptom profiles between early- and typical-onset groups were examined. RESULTS: One hundred three early-onset and 58 typical-onset patients were compared. Mixed episodes were more common in the early-onset group, while psychotic features and current substance use were more common in the typical-onset group. There was no significant difference in manic symptom severity ratings between early- and typical-onset groups (F = 1.8, df = 11, 144, p = 0.06). However, these groups differed in depressive (F = 4.2, df = 16, 139, p < 0.001) and positive psychotic (F = 2.8, df = 16, 139, p = 0.001) symptom profiles. Typical-onset bipolar patients reported more severe weight loss and formal thought disorder compared with early-onset patients. CONCLUSIONS: Depressive and positive psychotic symptoms may differ in association with age at onset among patients with bipolar disorder. Additional studies are necessary to determine whether homogeneous phenotypes of bipolar disorder can be delineated based upon age at onset.     

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.     

Cannabis use and non‐clinical dimensions of psychosis in university students presenting to primary care

Skinner R, Conlon L, Gibbons D, McDonald C. Cannabis use and non‐clinical dimensions of psychosis in university students presenting to primary care. Objective: To explore the relationship between cannabis use and self‐reported dimensions of psychosis in a population of university students presenting for any reason to primary care. Method: One thousand and forty‐nine students attending the Student Health Unit, National University of Ireland, Galway, completed self‐report questionnaires on alcohol and substance misuse, non‐clinical dimensions of psychosis [Community Assessment of Psychic Experiences (CAPE)], anxiety and depression [Hospital Anxiety and Depression Scale (HADS)]. Association of cannabis use with psychiatric symptoms was explored whilst controlling for confounds. Results: More frequent cannabis use was independently associated with greater intensity of positive, negative and depressive psychotic symptoms. The earlier the age of onset of cannabis use, the more positive psychotic symptoms were reported. Conclusion: These findings support the hypotheses that cannabis use increases the risk of developing psychotic symptoms and that this risk is further increased in those individuals who use cannabis more heavily and commence it at a younger age.     

Psychotic symptoms in an urban general medicine practice

OBJECTIVE: The authors' goals were to estimate the prevalence of psychotic symptoms among adults attending an urban general medical practice that serves a low-income population and to describe the mental health, social and occupational functioning, and mental health treatment of these patients. METHOD: Data were drawn from a recent study of adult primary care patients (N=1,005) in a large, urban, university-affiliated general medicine practice. During a medical visit, patients completed the psychotic disorders section of the Mini International Neuropsychiatric Interview, the Primary Care Evaluation of Mental Disorders, a drug use disorders screen, the Sheehan Disability Scale, and a questionnaire that probed demographic characteristics, health status, and mental health treatment. RESULTS: Two hundred ten (20.9%) patients reported one or more psychotic symptoms, most commonly auditory hallucinations. There was an inverse correlation between family income and the prevalence of psychotic symptoms and a positive association between prevalence and Hispanic ethnicity. Compared with patients without psychotic symptoms, patients with psychotic symptoms were significantly more likely to have major depression (42.4% versus 12.6%), panic disorder (24.8% versus 4.0%), generalized anxiety disorder (38.6% versus 8.4%), and alcohol use disorder (12.9% versus 5.0%). They were also more likely to report current suicidal ideation (20.0% versus 3.5%), recent work loss (55.0% versus 35.6%), and marital distress (28.6% versus 13.0%). Approximately one-half of the patients with psychotic symptoms (47.6%) had taken a prescribed psychotropic medication during the last month. CONCLUSIONS: Psychotic symptoms were highly prevalent in this primary care practice. These patients were at risk for several common mental disorders and often reported impaired work and social functioning. Future research should clarify the extent to which psychotic symptom reports among Hispanic patients are affected by culturally patterned idioms of distress. Clinicians who work in primary care practices that serve low-income patient populations should routinely inquire about psychotic symptoms.     

Psychotic symptoms and emotional distress in patients with Guillain-Barré syndrome

Psychological disturbances in 49 most severely compromised Guillain-Barré syndrome patients were prospectively studied by a semistructured interview and assessed by repeat psychiatric examination during the patients' stay in the neuro-intensive care unit (ICU). Additional information was obtained from attending physicians, nurses and relatives. Anxiety (82%), acute stress disorder, depressive episodes (67%) and brief reactive psychosis (25%) were observed, with oneiroid psychosis (14%) among the latter. Psychotic episodes were strongly associated (p < 0.001) with severe tetraparesis, artificial ventilation and multiple cranial nerve dysfunction. CSF protein concentration was also correlated with the occurrence of psychotic symptoms. Patients themselves experienced loss of communication to be the most difficult condition to cope with. Fifty-five percent explicitly felt reassured by the environment of the ICU and 90% described contact with relatives to be most helpful. Our data suggest that motor deprivation and loss of communication are the conditions most closely connected with the occurrence of psychotic symptoms. Therapeutically, continuous psychosocial support and psychopharmacological measures may both be valuable tools to ameliorate distress.     

Psychiatric symptoms related to interferon therapy for chronic hepatitis C: clinical features and prognosis

Psychiatric symptoms during interferon (IFN) therapy for viral hepatitis have been a crucial problem in consultation-liaison psychiatry. However, there have been few studies on psychiatric management for these symptoms and their prognosis. Among 943 patients who were treated with IFN for chronic hepatitis C between 1991 and 1995, 43 patients (4.6%) developed psychiatric symptoms during IFN treatment. Three patients (0.3%), with pre-existing psychiatric disorders showed aggravated symptoms and were excluded from the study. All three patients were able to finish the IFN therapy with psychiatric management. Forty patients (4.2%) manifested psychiatric symptoms induced by IFN. Thirteen patients (1.4%) were diagnosed as anxiety disorder and 21 patients (2.2%) revealed mood disorder with depressive features. There were other psychiatric disorders in six patients (0.6%), including psychotic disorder with delusions/hallucinations in four patients (0.4%), mood disorder with manic features in one patient (0.1%) and delirium in one patient (0.1%). Women developed psychiatric symptoms significantly more than men. Ten of 40 patients (25%) stopped IFN treatment because of manifesting psychiatric symptoms induced by IFN. Twelve patients (30%) required psychiatric treatment for more than 24weeks after ceasing IFN, and seven patients still had anxiety, insomnia and mild hypothymia at the end of the present study. Statistical analysis revealed that IFN-beta therapy and psychiatric manifestations including psychotic symptoms, delirium and manic symptoms were significantly related to long-term psychiatric problems. There are considerable numbers of patients who have required long-term psychiatric management even after cessation of IFN treatment.     

Manic symptoms and impulsivity during bipolar depressive episodes

OBJECTIVES: In contrast to the extensive literature on the frequent occurrence of depressive symptoms in manic patients, there is little information about manic symptoms in bipolar depressions. Impulsivity is a prominent component of the manic syndrome, so manic features during depressive syndromes may be associated with impulsivity and its consequences, including increased risk of substance abuse and suicidal behavior. Therefore, we investigated the prevalence of manic symptoms and their relationships to impulsivity and clinical characteristics in patients with bipolar depressive episodes. METHODS: In 56 bipolar I or II depressed subjects, we investigated the presence of manic symptoms, using Mania Rating Scale (MRS) scores from the Schedule for Affective Disorders and Schizophrenia (SADS), and examined its association with other psychiatric symptoms (depression, anxiety, and psychosis), age of onset, history of alcohol and/or other substance abuse and of suicidal behavior, and measures of impulsivity. RESULTS: MRS ranged from 0 to 29 (25th-75th percentile, range 4-13), and correlated significantly with anxiety and psychosis, but not with depression, suggesting the superimposition of a separate psychopathological mechanism. Impulsivity and history of substance abuse, head trauma, or suicide attempt increased with increasing MRS. Receiver-operating curve analysis showed that MRS could divide patients into two groups based on history of alcohol abuse and suicide attempt, with an inflection point corresponding to an MRS score of 6. DISCUSSION: Even modest manic symptoms during bipolar depressive episodes were associated with greater impulsivity, and with histories of alcohol abuse and suicide attempts. Manic symptoms during depressive episodes suggest the presence of a potentially dangerous combination of depression and impulsivity.     

Manic episode with psychotic symptoms in a patient with Parkinson's disease treated by subthalamic nucleus stimulation: improvement on switching the target

Manic symptoms have been reported as adverse effects of bilateral deep brain stimulation (DBS) of the subthalamic nucleus (STN) in patients with Parkinson's disease. In previous reports, manic symptoms were described as transient, not associated with psychotic features, and improved spontaneously or with medical adjustments. The medial part of the STN seems to play a key role in the occurrence of these manic symptoms. We report the case of a manic episode with psychotic symptoms in a patient with Parkinson's disease treated by STN DBS, which improved with a change in the stimulated target. This case demonstrates the efficacy of switching the stimulation target against a manic episode with psychotic features secondary to DBS.     

Psychiatric Symptoms Endorsed by Somatization Disorder Patients in a Psychiatric Clinic

Patients with somatization disorder (SD) endorse high rates of psychiatric symptoms. However, prior studies have not addressed whether these endorsed symptoms reflect underlying psychiatric illness or whether they represent symptom overendorsement mirroring somatic complaints in patients with SD. Thirty-two female outpatients with SD and 101 with other psychiatric disorders completed a checklist of current and lifetime psychiatric symptoms. These findings were analyzed with respect to the diagnoses given by their treating psychiatrists. Patients with SD displayed significantly more current and lifetime psychiatric symptoms than did patients without either SD or cluster B personality disorder. Patients with SD endorsed a large number of psychotic, manic, depressive, and anxiety symptoms; however, they endorsed few alcohol use disorder symptoms. Psychotic and manic symptoms endorsed by patients with SD did not reflect their clinical diagnoses: only two patients with SD carried an additional clinician diagnosis of either schizophrenia or bipolar disorder, despite high rates of endorsed symptoms by the group. Patients with cluster B personality disorders but without SD showed a symptom profile similar to that of patients with SD. Psychiatric outpatients with SD endorse many more psychiatric symptoms than do other psychiatric patients. Patients with SD in the psychiatric treatment setting may mimic other psychiatric illnesses; therefore, SD should be considered in the differential diagnosis for a wide variety of psychiatric illness, including psychotic and mood disorders     

Serotonin reuptake inhibitors, paranoia, and the ventral basal ganglia.

Antidepressants have previously been associated with paranoid reactions in psychiatric patients. Five cases of paranoid exacerbation with the serotonin reuptake inhibitors fluoxetine and amitriptyline are reported here. Elements common to these cases included a history of paranoid symptomatology and the concomitant occurrence of depressive and psychotic symptoms. Complicated depressive disorders (including atypicality of course and symptomatology, chronicity, psychosis, bipolarity, and secondary onset in the course of a primary psychosis) may present particular vulnerability to paranoid exacerbations associated with serotonin reuptake inhibitors. Although the pharmacology and neurobiology of paranoia remain cryptic, several mechanisms, including 5HT3 receptor-mediated dopamine release, beta-noradrenergic receptor downregulation, or GABAB receptor upregulation acting in the vicinity of the ventral basal ganglia (possibly in lateral orbitofrontal or anterior cingulate circuits), might apply to this phenomenon. These cases call attention to possible paranoid exacerbations with serotonin reuptake blockers in select patients and raise neurobiological considerations regarding paranoia.     

Lithium treatment of manic episodes with psychotic features in prepubertal children

The authors describe the manic symptoms, family psychiatric histories, and psychotic symptoms of 10 prepubertal children 6-12 years old who had a DSM-III diagnosis of manic episode with psychotic features. All of the children improved when treated with lithium alone. Improvement in both manic and psychotic symptoms was noted an average of 11 days after lithium administration was started.     

Clinical predictors of acute response with quetiapine in psychotic mood disorders

BACKGROUND: In controlled studies of patients with schizophrenia, the atypical antipsychotic quetiapine, 300 mg/day, has been shown to be as effective in the treatment of positive and negative symptoms as haloperidol. However, little is known about the efficacy of quetiapine in patients with psychotic mood disorders. The purpose of this study was to assess the efficacy of quetiapine in the treatment of psychotic mood disorders in comparison with nonaffective psychotic disorders and identify clinical factors associated with quetiapine response. METHOD: In a naturalistic setting, by reviewing medical records, we assessed response to quetiapine and factors associated with response to quetiapine in 145 consecutive patients newly treated with the drug at a nonprofit academic psychiatric hospital. These patients had received a discharge diagnosis of bipolar disorder (manic, mixed, or depressive type), major depression with psychotic features, schizophrenia, schizoaffective disorder (bipolar or depressive type), delusional disorder, or psychosis not otherwise specified (NOS) according to DSM-IV criteria. RESULTS: Patients with a diagnosis of bipolar disorder, manic, mixed, or depressed and schizoaffective disorder, bipolar type displayed higher response rates (> 74%) compared with patients with schizophrenia. However, this finding did not achieve statistical significance. A diagnosis of major depression with psychotic features (p = .02) and longer duration of illness (p = .03) were associated with less chance of responding. CONCLUSION: Quetiapine may be a useful alternative or adjunctive treatment for patients with bipolar and schizoaffective disorders.     

Psychotic symptoms in combat-related posttraumatic stress disorder

BACKGROUND: Posttraumatic stress disorder (PTSD) is known often to be comorbid with other anxiety, mood, and substance use disorders. Psychotic symptoms have also been noted in PTSD and have been reported to be more common in Hispanic veterans. However, the occurrence of psychotic symptoms, including the degree to which they are accounted for by comorbid disorders, have received limited systematic investigation. Our study objectives were to assess psychotic symptoms according to DSM-III-R criteria in patients with a primary diagnosis of combat-related PTSD and determine the associations of those symptoms with psychiatric comorbidity and ethnicity. METHOD: Fifty-three male combat veterans consecutively admitted to a PTSD rehabilitation unit were assessed for psychotic symptoms and Axis I disorders. Ninety-one percent were Vietnam veterans; 72% were white, 17% were Hispanic, and 11% were black. Associations between psychotic symptoms and comorbid depression, substance use disorders, and minority status were compared by chi-square analyses; associations between psychotic symptoms and both PTSD and dissociative symptom severity were compared by t test analysis. RESULTS: Forty percent of patients reported a psychotic symptom or symptoms in the preceding 6 months. These symptoms featured auditory hallucinations in all but 1 case. The psychotic symptoms typically reflected combat-themes and guilt, were nonbizarre, and were not usually associated with formal thought disorder or flat or inappropriate affect. Psychotic symptoms were significantly associated with current major depression (p < .02), but not with alcohol or drug abuse or with self-rated PTSD and dissociation severity. Psychotic symptoms and current major depression were more common in minority (black and Hispanic) than white veterans (p < .002). CONCLUSION: Psychotic symptoms can be a feature of combat-related PTSD and appear to be associated with major depression. The association with minority status may be a function of comorbidity.
