Impulse control disorders in adult psychiatric inpatients

OBJECTIVE: The authors' goal was to examine the prevalence of impulse control disorders in psychiatric inpatients. METHOD: They used the Minnesota Impulsive Disorders Interview, a semistructured clinical interview assessing pathological gambling, trichotillomania, kleptomania, pyromania, intermittent explosive disorder, compulsive buying, and compulsive sexual behavior, to screen 204 consecutively admitted psychiatric inpatients. One hundred twelve of the inpatients were women (54.9%), and the mean age of the 204 inpatients was 40.5 years (SD=13.2, range=18-83). Patients whose screen was positive for an impulse control disorder were evaluated with structured clinical interviews. RESULTS: Sixty-three patients (30.9%) were diagnosed with at least one current impulse control disorder. The most common impulse control disorders were compulsive buying (N=19 [9.3%]), kleptomania (N=16 [7.8%]), and pathological gambling (N=14 [6.9%]). Patients with and without co-occurring impulse control disorders did not differ significantly from each other on demographic measures or number or type of psychiatric diagnoses other than impulse control disorders. CONCLUSIONS: Impulse control disorders appear common among psychiatric inpatients. Additional, larger studies are needed to examine the prevalence of impulse control disorders in the general population and specific psychiatric groups.     

Imbalance Model of Heart Rate Variability and Pulse Wave Velocity in Psychotic and Nonpsychotic Disorders

ObjectivesPatients with psychiatric disorders have an increased risk of cardiovascular pathologies. A bidirectional feedback model between the brain and heart exists widely in both psychotic and nonpsychotic disorders. The aim of this study was to compare heart rate variability (HRV) and pulse wave velocity (PWV) functions between patients with psychotic and nonpsychotic disorders and to investigate whether subgroups defined by HRV and PWV features improve the transdiagnostic psychopathology of psychiatric classification.MethodsIn total, 3448 consecutive patients who visited psychiatric or psychological health services with psychotic (N = 1839) and nonpsychotic disorders (N = 1609) and were drug-free for at least 2 weeks were selected. HRV and PWV indicators were measured via finger photoplethysmography during a 5-minute period of rest. Canonical variates were generated through HRV and PWV indicators by canonical correlation analysis (CCA).ResultsAll HRV indicators but none of the PWV indicators were significantly reduced in the psychotic group relative to those in the nonpsychotic group. After adjusting for age, gender, and body mass index, many indices of HRV were significantly reduced in the psychotic group compared with those in the nonpsychotic group. CCA analysis revealed 2 subgroups defined by distinct and relatively homogeneous patterns along HRV and PWV dimensions and comprising 19.0% (subgroup 1, n = 655) and 80.9% (subgroup 2, n = 2781) of the sample, each with distinctive features of HRV and PWV functions.ConclusionsHRV functions are significantly impaired among psychiatric patients, especially in those with psychosis. Our results highlight important subgroups of psychiatric patients that have distinct features of HRV and PWV which transcend current diagnostic boundaries.     

Impulse control disorders and depression in Finnish patients with Parkinson's disease

IntroductionImpulse control disorders occur frequently in patients with Parkinson's disease. However, the frequencies have been investigated mainly in patients from secondary or tertiary care centers, and thus, the prevalence rates in general community are not known.ObjectiveOur objective was to study the prevalence rates of impulse control disorders and related factors in a large, non-selected sample of Parkinson's disease patients.MethodsWe conducted a cross-sectional survey among Parkinson's disease patients from Finnish Parkinson Association [n = 575; 365 men, 240 women, median age 64 (range 43–90) years]. Problem and pathological gambling were estimated with the South Oaks Gambling Screen, risk for impulse control disorders with the validated Questionnaire for Impulsive–Compulsive Disorders in Parkinson's Disease, and depression with the Beck Depression Inventory.ResultsThe frequency of pathological gambling was 7.0%. The overall frequency of a positive screen for an impulse control disorder was 34.8%, and 12.5% of the patients screened positive for multiple disorders. Depressive symptoms were statistically the most important factor in explaining variance in impulse control disorder risk, even more than sex, age, age of disease onset, alcohol use, or medication.ConclusionsThe high proportion of patients screened positive for impulse control disorders in a non-selected sample emphasize the importance of routine screening of these disorders in Parkinson's disease. Pathological gambling prevalence in Parkinson's disease is seven times higher than in the general population in Finland. The results underline the importance of depression in impulse control disorders associated with Parkinson's disease.     

Gambling disorders among homeless persons with substance use disorders seeking treatment at a community center

OBJECTIVES: Epidemiological research suggests that homelessness is a risk factor for elevated levels of psychiatric comorbidity and other health risks. This study examined the prevalence of disordered gambling and its association with treatment of psychiatric and substance use disorders among a cohort of homeless people seeking treatment at a community services program. METHODS: Between 1998 and 2000, intake workers evaluated the level of gambling disorder among 171 consecutive homeless persons with substance use disorders who sought treatment at the Moving Ahead Program in Boston. Program staff administered the DSM-IV subscale of the Massachusetts Gambling Screen at intake. RESULTS: The prevalence rates of level 2 and level 3 gambling disorders were 12.8 percent and 5.5 percent, respectively. These rates are higher than that of the general adult population but comparable to those of other patients with substance use disorders and psychiatric diagnoses. Program participants with level 3 gambling disorders had been homeless more often and at a younger age and had had less substance abuse treatment and more psychiatric treatment than participants with level 1 or level 2 gambling disorders. Participants with level 2 gambling disorders had been homeless more often and for a longer duration than participants without gambling disorders. CONCLUSIONS: These findings should encourage clinicians working with homeless people to screen for gambling-related problems and disorders.     

Prognosis of postpartum psychiatric disorders in a Turkish sample

Objective

The postpartum period represents a time of increased risk for psychiatric disorders. Postpartum depression is especially very common. Many aetiological risk factors have been reported for postpartum psychiatric disorders. The purpose of this study was to evaluate the postpartum psychiatric disorders in a Turkish sample and discuss their course.

Methods

The files of 6000 inpatients who were admitted to Gazi University School of Medicine Psychiatry Department were evaluated retrospectively, and 67 patients were chosen whose psychiatric illness had began puerperally. These patients were grouped according to age of onset of the illness, number of episodes and the type of these episodes, their postpartum psychiatric diagnoses and illness prognosis.

Results

Of 6000 patients, 67 (1.11%) were diagnosed as having a postpartum psychiatric disorder: 56.7% (n=38) were diagnosed as having a postpartum psychotic disorder, while 35.8% (n=24) as having an affective disorder. Forty-seven patients (70.1%) received a diagnosis of major psychiatric disorder during their follow-up.

Conclusion

These results show that postpartum diagnoses may show a chronic course and cause a life-time psychiatric illness and therefore patients should be monitored carefully for psychotic symptoms even after the acute period is over.     

Impulsivity profiles in pathological slot machine gamblers

IntroductionIn gambling disorder (GD), impulsivity has been related with severity, treatment outcome and a greater dropout rate. The aim of the study is to obtain an empirical classification of GD patients based on their impulsivity and compare the resulting groups in terms of sociodemographic, clinical and gambling behavior variables.Methods126 patients with slot machine GD attending the Pathological Gambling Unit between 2013 and 2016 were included. The UPPS-P Impulsive Behavior Scale was used to assess impulsivity, and the severity of past-year gambling behavior was established with the Screen for Gambling problems questionnaire (NODS). Depression and anxiety symptoms and executive function were also assessed. A two-step cluster analysis was carried out to determine impulsivity profiles.ResultsAccording to the UPPS-P data, two clusters were generated. Cluster 1 showed the highest scores on all the UPPS-P subscales, whereas patients from cluster 2 exhibited only high scores on two UPPS-P subscales: Negative Urgency and Lack of premeditation. Additionally, patients on cluster 1 were younger and showed significantly higher scores on the Beck Depression Inventory and on the State-Trait Anxiety Inventory questionnaires, worse emotional regulation and executive functioning, and reported more psychiatric comorbidity compared to patients in cluster 2. With regard to gambling behavior, cluster 1 patients had significantly higher NODS scores and a higher percentage presented active gambling behavior at treatment start than in cluster 2.ConclusionsWe found two impulsivity subtypes of slot machine gamblers. Patients with high impulsivity showed more severe gambling behavior, more clinical psychopathology and worse emotional regulation and executive functioning than those with lower levels of impulsivity. These two different clinical profiles may require different therapeutic approaches.     

Electroencephalographic findings in schizophreniform and affective disorders

Objective: Pathological findings in electroencephalography (EEG) are discussed as a possible marker of organic mental disorders and a therapeutic response to anticonvulsive medication under these conditions.

Methods: We compared the prevalence of EEG abnormalities in 100 patients with schizophrenia, 100 patients with schizoaffective disorder, 51 patients with acute polymorphic psychotic disorder, 100 patients with bipolar disorder, 100 patients with unipolar major depression and 76 healthy control subjects with the findings of a previous study using well-diagnosed, large control samples (13,658 pilots and aircrew personnel).

Results: We detected an increased number of pathological EEG findings with intermittent rhythmic delta or theta activity in 7% of patients with schizophrenia, 7% of patients with schizoaffective disorder, 5.9% of patients with acute polymorphic psychosis, 6% of patients with bipolar disorder, 4% of unipolar depressed patients and 3.9% of the own control group, compared to 1% of strictly controlled healthy subjects. One-sided logistic regression revealed an association between pathological EEGs and the diagnosis of schizophrenia (Wald W?=?3.466, p?=?0.0315), schizoaffective disorder (W?=?3.466, p?=?0.0315) and bipolar disorder (W?=?2.862, p?=?0.0455).

Conclusions: We suggest that the previously developed local area network inhibition model for a potential paraepileptic pathomechanism can explain the relevance of such findings in different psychiatric disorders.     

Mood and anxiety disorders among inpatients of a university hospital in Turkey

Objective

The aim of the study was to assess the prevalence of mood and anxiety disorders among inpatients and the relationship between sociodemographic factors, medical illnesses and treatments.

Methods

In the present study, we selected 650 inpatients from all clinics except psychiatry and pediatrics in a general hospital by a simple random sampling method. Based on the exclusion criteria, 57 patients were excluded. Mood and anxiety disorders were determined by means of the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition.

Results

Of the participants, 226 (37.5%) had a psychiatric disorder, 87 (14.4) had a mood disorder and 146 (24.2%) had an anxiety disorder. The most common specific diagnoses were not otherwise specified as anxiety disorder (9.5%), major depression (8.6%) and generalized anxiety disorder (7.6%). While the overall prevalence was highest in the hematology clinic (60.0%), it was lowest in the clinic of infectious diseases (22.7%). Logistic regression analysis indicated that the independent factors associated with psychiatric disorders were being of the female gender and a personal history of psychiatric disorders.

Conclusions

In conclusion, results of the present study suggest that mood and anxiety disorders were frequently observed among inpatients, particularly in female patients and those with an individual history of psychiatric disorder. Successful treatment of these disorders may positively contribute to the course of the disease in inpatients. However, this assumption should be confirmed by further studies.     

Mental disorders among adolescents in juvenile detention and correctional facilities: a systematic review and metaregression analysis of 25 surveys

ObjectiveTo systematically review and perform a meta-analysis of the research literature on the prevalence of mental disorders in adolescents in juvenile detention and correctional facilities.MethodSurveys of psychiatric morbidity based on interviews of unselected populations of detained children and adolescents were identified by computer-assisted searches, scanning of reference lists, hand-searching of journals, and correspondence with authors of relevant reports. The sex-specific prevalence of mental disorders (psychotic illness, major depression, attention-deficit/hyperactivity disorder [ADHD], and conduct disorder) together with potentially moderating study characteristics were abstracted from publications. Statistical analysis involved metaregression to identify possible causes of differences in disorder prevalence across surveys.ResultsTwenty-five surveys involving 13,778 boys and 2,972 girls (mean age 15.6 years, range 10–19 years) met inclusion criteria. Among boys, 3.3% (95% confidence interval [Cl] 3.0%-3.6%) were diagnosed with psychotic illness, 10.6% (7.3%-13.9%) with major depression, 11.7% (4.1%-19.2%) with ADHD, and 52.8% (40.9%-64.7%) with conduct disorder. Among girls, 2.7% (2.0%-3.4%) were diagnosed with psychotic illness, 29.2% (21.9%-36.5%) with major depression, 18.5% (9.3%-27.7%) with ADHD, and 52.8% (32.4%-73.2%) with conduct disorder. Metaregression suggested that surveys using the Diagnostic Interview Schedule for Children yielded lower prevalence estimates for depression, ADHD, and conduct disorder, whereas studies with psychiatrists acting as interviewers had lower prevalence estimates only of depression.ConclusionsAdolescents in detention and correctional facilities were about 10 times more likely to suffer from psychosis than the general adolescent population. Girls were more often diagnosed with major depression than were boys, contrary to findings from adult prisoners and general population surveys. The findings have implications for the provision of psychiatric services for adolescents in detention. J. Am. Acad. Child Adolesc. Psychiatry, 2008; 47(9):1010–1019.     

Comorbidity of DSM-IV pathological gambling and other psychiatric disorders: results from the National Epidemiologic Survey on Alcohol and Related Conditions

OBJECTIVE: To present nationally representative data on lifetime prevalence and comorbidity of pathological gambling with other psychiatric disorders and to evaluate sex differences in the strength of the comorbid associations. METHOD: Data were derived from a large national sample of the United States. Some 43,093 household and group quarters residents age 18 years and older participated in the 2001-2002 survey. Prevalence and associations of lifetime pathological gambling and other lifetime psychiatric disorders are presented. The diagnostic interview was the National Institute on Alcohol Abuse and Alcoholism Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV Version. Fifteen symptom items operationalized the 10 pathological gambling criteria. RESULTS: The lifetime prevalence rate of pathological gambling was 0.42%. Almost three quarters (73.2%) of pathological gamblers had an alcohol use disorder, 38.1% had a drug use disorder, 60.4% had nicotine dependence, 49.6% had a mood disorder, 41.3% had an anxiety disorder, and 60.8% had a personality disorder. A large majority of the associations between pathological gambling and substance use, mood, anxiety, and personality disorders were overwhelmingly positive and significant (p < .05), even after controlling for sociodemographic and socioeconomic characteristics. Male sex, black race, divorced/separated/widowed marital status, middle age, and living in the West and Midwest were associated with increased risk for pathological gambling. Further, associations between alcohol dependence, any drug use disorder, drug abuse, nicotine dependence, major depressive episode, and generalized anxiety disorder and pathological gambling were stronger among women than men (p > .05). CONCLUSION: Pathological gambling is highly comorbid with substance use, mood, anxiety, and personality disorders, suggesting that treatment for one condition should involve assessment and possible concomitant treatment for comorbid conditions.     

Development of the Gambling Disorder Identification Test: Results from an international Delphi and consensus process

ObjectivesDiverse instruments are used to measure problem gambling and Gambling Disorder intervention outcomes. The 2004 Banff consensus agreement proposed necessary features for reporting gambling treatment efficacy. To address the challenge of including these features in a single instrument, a process was initiated to develop the Gambling Disorder Identification Test (GDIT), as an instrument analogous to the Alcohol Use Disorders Identification Test and the Drug Use Disorders Identification Test.MethodsGambling experts from 10 countries participated in an international two‐round Delphi (n = 61; n = 30), rating 30 items proposed for inclusion in the GDIT. Gambling researchers and clinicians from several countries participated in three consensus meetings (n = 10; n = 4; n = 3). User feedback was obtained from individuals with experience of problem gambling (n = 12) and from treatment‐seekers with Gambling Disorder (n = 8).ResultsTen items fulfilled Delphi consensus criteria for inclusion in the GDIT (M ≥ 7 on a scale of 1–9 in the second round). Item‐related issues were addressed, and four more items were added to conform to the Banff agreement recommendations, yielding a final draft version of the GDIT with 14 items in three domains: gambling behavior, gambling symptoms and negative consequences.ConclusionsThis study established preliminary construct and face validity for the GDIT.     

Pathologic gambling and bankruptcy

Background

Although prior studies have examined rates of bankruptcy in pathologic gambling (PG), there are only limited data regarding the clinical correlates of those with PG who declare bankruptcy because of gambling.

Method

Five hundred seventeen consecutive subjects with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, PG (54.7% females; mean age 47.6 years) were grouped into 2 categories: those who had (n = 93; 18.0%) and had not (n = 424; 82.0%) declared bankruptcy secondary to gambling. Groups were compared on clinical characteristics, gambling severity (using the Yale-Brown Obsessive-Compulsive Scale Modified for Pathological Gambling, Gambling Symptom Assessment Scale; Clinical Global Impression—severity scale, and time and money spent gambling), and psychiatric comorbidity.

Results

Gamblers who had declared bankruptcy were more likely to be single (P = .004); have an earlier age of problem gambling onset (P = .032); and have more financial (P < .001), work-related (P = .006), marital (P < .001), and legal (P < .001) problems secondary to their gambling. They also reported higher rates of depressive disorders (P < .001), substance use disorders (P = .005) and were more likely to be daily users of nicotine (P = .022). Money spent gambling did not differ significantly between groups.

Conclusion

These preliminary results suggest that bankruptcy in PG may be associated with specific clinical differences. Treatment strategies may want to assess bankruptcy status to develop more effective treatments that take account of these clinical differences.     

Fréquence et facteurs de risque du jeu pathologique chez une population de joueurs à Casablanca

Introduction

Pathological gambling is a major psychiatric disorder and a public health problem that has gained a lot of attention in the last few years. The problems caused by gambling are increasingly serious. The prevalence of pathological or compulsive gambling varies from 0.8 to 2% in Europe, Canada and the USA.

Aim of the study

A study has been conducted in different gambling spots in Casablanca to measure the frequency of pathological gambling in Morocco and to determine the risk factors and the socio-cultural factors associated with it.

Design of the study

The collection of data was conducted in the most frequented gambling spots. The first part of the questionnaire permitted the gathering of the sociodemographic characteristics and drug addictions as well as the psychiatric and legal histories. The detection and diagnosis of pathological gambling was conducted using through the South Oaks Gambling Screen (SOCS) questionnaire, which has been translated to Arabic to suit the needs of the study.

Participants in the study

Two hundred men were retained out of the 243 interviewed, which represent a participation rate of 82%. The frequency of pathological gambling among a population of gamblers is 53%. The mean age of the sample was 42.3 more or less 10.70 years. Thirty-six percent of those interviewed had a monthly income of less than 2000 dirhams (200 euros). Horse and greyhound racing were the most popular forms of gambling among those interviewed, with rates of 91 and 60% respectively. Individuals with an educational level of no more than primary school, a monthly income of less than 5000 dirhams (500 euros), a personal psychiatric history, and a drug addiction, are most risky to be pathological gamblers.

Conclusion

The topic pathological gambling has been studied very little in Arab and Islamic countries, and it is necessary to conduct larger epidemiological studies on the general population to inquire about its prevalence, risk factors as well as its psychiatric characteristics.     

Impulse control disorders in elderly patients

Objective

There is no epidemiological study on the prevalence of impulse control disorders (ICDs) in the elderly population. The studies on ICDs in elderly patients are limited and some of them are case reports about pathological gambling and kleptomania. The comorbidity of other psychiatric disorders makes diagnosis difficult and has negative effects on both treatment and the prognosis of ICDs. The aim of this study was to determine the prevalence of ICDs among elderly patients and to evaluate the related sociodemographic and clinical features.

Method

A total of 76 patients aged 60 and over who have been referred to our outpatient clinics in a one-year period were included in the study. A demographic data form was completed. The Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) was used to determine axis I psychiatric disorders. The prevalence of ICDs was investigated by using the modified version of the Minnesota Impulse Disorders Interview (MIDI). Impulsivity was measured with the Barratt Impulsiveness Scale Version 11 (BIS-11). The Mini-Mental State Examination (MMSE) test was performed to evaluate the cognitive status of patients and to exclude the diagnosis of dementia. In addition, all patients completed Symptom Check List-90 (SCL-90).

Results

The prevalence rate of at least one comorbid ICD in our sample was 17%. When patients with a diagnosis of ICDs not otherwise specified (ICD-NOS) were included, the prevalence rate increased to 22.4%. The most common ICD was intermittent explosive disorder (15.8%), followed by pathological gambling (9.2%). The majority of the sample was men (54%), married (80%), had a high school education (51%), and mid-level socioeconomic status (79%). The only statistically significant difference between the sociodemographic characteristics of patients with or without ICDs was gender. The lifetime prevalence of ICDs was 34.1% in men and 8.6% in women. The prevalence of childhood conduct disorder was significantly higher in the group with ICD. There was no statistically significant difference in the number of suicide attempts, history of physical illness and family history of psychiatric disorders between the groups with or without ICDs. Comorbidity of alcohol/substance abuse was found to be 17.6% in patients with ICD whereas no cases were found in the group without ICD.

Conclusion

The result of this study has shown that approximately one fifth of patients over 60 years had at least one lifetime ICD comorbidity. The prevalence rates of ICDs seem to decrease with aging. The male gender and childhood conduct disorder are related with higher prevalence rates of ICDs in elderly.     

Risk Factors for Full- and Partial-Syndrome Early Adolescent Eating Disorders: A Population-Based Pregnancy Cohort Study

ObjectiveTo identify prospective predictors of eating disorders in a population-based sample of 14-year-old boys and girls, using previously collected antenatal, biomedical, familial, demographic, and psychosocial data.MethodParticipants (N = 1,597) were drawn from the Western Australian Pregnancy Cohort (Raine) Study. Data were collected during pregnancy, at birth, and when children were aged 1, 2, 5, 8, 10, and 14 years. An adapted version of the Eating Disorder Examination Questionnaire was used to assess eating disorder symptoms at age 14 years. Logistic regression was used to identify prospective predictors of eating disorder caseness, relative to general control and psychiatric control groups.ResultsAt age 14 years, 6% of the sample met full or partial criteria for a DSM-IV eating disorder. Being female and being perceived as overweight by one's parent were the strongest predictors of eating disorder caseness in the final multivariate models, relative to both control groups. Maternal body mass index, social problems, low social-related self-efficacy, and neurocognitive difficulties were also predictive of eating disorder caseness relative to the general control group only.ConclusionsThe results suggest that parent's perceptions of their child's weight are more powerful than objective child body weight in predicting the development of eating disorders. Parent-perceived child overweight was also a specific risk factor for eating disorders, whereas elevated maternal weight and childhood psychosocial difficulties seem to be associated with increased risk for psychiatric disturbance more generally. These results have implications for the prevention of eating disorders, particularly in light of recent increases in the prevalence of childhood obesity.     

Impulse control disorders in psychiatric inpatients

The aim of this study was to examine the prevalence of impulse control disorders (ICDs) in a European psychiatric inpatient sample. Two hundred thirty four consecutive psychiatric inpatients (62% female) were examined using a module of the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders fourth edition (DSM-IV) that has been developed for ICDs (SCID-ICD). In addition to intermittent explosive disorder, pyromania, kleptomania, pathological gambling, and trichotillomania, the proposed ICDs not otherwise specified were assessed, including compulsive buying, nonparaphilic compulsive sexual behavior, pathological internet use, and pathological skin picking. Based on the SCID-ICD, a lifetime ICD rate of 23.5% and a current ICD rate of 18.8% were found. The most frequent ICDs were pathological skin picking (lifetime 7.3%, current 6.8%), compulsive buying (lifetime 6.8%, current 6.0%), and intermittent explosive disorder (lifetime 5.6%, current 3.4%). In contrast, referring to admission diagnoses taken from patients' charts only 3.8% of the inpatients were diagnosed with any current ICD. Individuals with comorbid ICD were significantly younger and had more admission diagnoses other than ICD. The results suggest high rates of ICDs among psychiatric inpatients that remain to be under-diagnosed in clinical routine.     

Psychiatric disorders in children with autism spectrum disorders: prevalence, comorbidity, and associated factors in a population-derived sample

ObjectiveAutism spectrum disorders are now recognized to occur in up to 1% of the population and to be a major public health concern because of their early onset, lifelong persistence, and high levels of associated impairment. Little is known about the associated psychiatric disorders that may contribute to impairment. We identify the rates and type of psychiatric comorbidity associated with ASDs and explore the associations with variables identified as risk factors for child psychiatric disorders.MethodA subgroup of 112 ten- to 14-year old children from a population-derived cohort was assessed for other child psychiatric disorders (3 months' prevalence) through parent interview using the Child and Adolescent Psychiatric Assessment. DSM-IV diagnoses for childhood anxiety disorders, depressive disorders, oppositional defiant and conduct disorders, attention-deficit/hyperactivity disorder, tic disorders, trichotillomania, enuresis, and encopresis were identified.ResultsSeventy percent of participants had at least one comorbid disorder and 41% had two or more. The most common diagnoses were social anxiety disorder (29.2%, 95% confidence interval [Cl)] 13.2-45.1), attention-deficit/hyperactivity disorder (28.2%, 95% Cl 13.3-43.0), and oppositional defiant disorder (28.1 %, 95% Cl 13.9-42.2). Of those with attention-deficit/hyperactivity disorder, 84% received a second comorbid diagnosis. There were few associations between putative risk factors and psychiatric disorder.ConclusionsPsychiatric disorders are common and frequently multiple in children with autism spectrum disorders. They may provide targets for intervention and should be routinely evaluated in the clinical assessment of this group. J. Am. Acad. Child Adolesc. Psychiatry, 2008;47(8):921-929.     

The efficacy of ECT in adults with mental retardation experiencing psychiatric disorders

There is a paucity of empirical data establishing the efficacy of electroconvulsive therapy (ECT) in patients with mental retardation and psychiatric disorders. This study examines the efficacy of ECT on specific symptoms and between psychiatric diagnoses in patients with mental retardation who are psychiatrically ill. A chart review was performed on 20 inpatients who had received ECT on a dedicated Mental Retardation-Dual Diagnosis Unit and were divided into 3 categories: mood disorders (n = 12), psychotic disorders (n = 6), and intermittent explosive disorder (n = 2). Ratings were performed 1 week before ECT treatment and 1-week after its termination using the Aberrant Behavior Checklist and the Clinical Global Impressions Severity Scale. A repeated-measures analysis of variance comparing Aberrant Behavior Checklist scale scores revealed a significant time-by-treatment interaction (F = 75.43, df = 1,9, P = 0.000, 2 t). The mood disorder and psychotic disorder groups had significantly lower irritability and hyperactivity scores after treatment compared with the intermittent explosive disorder group. The Clinical Global Impressions Severity Scale rating scores showed significant improvement in the mood disorders group (67%), in contrast to the intermittent explosive disorder group (0%). Our data suggests the utility of ECT for patients with mental retardation who also have treatment-resistant mood disorders and psychotic disorders, particularly with symptoms of hyperactivity and irritability. The data are sufficiently encouraging to justify prospective research of this question.
