A Systematic Review on Cognitive Effects of Electroconvulsive Therapy in Asian Patients

Objective@#Electroconvulsive therapy (ECT) is the most efficacious treatment for many major mental illnesses but is limited by cognitive side effects. However, research on the pattern and severity of ECT-related cognitive side effects is inconsistent. Furthermore, little is known about the cognitive effects of ECT in Asian populations. A systematic review was conducted to examine objective cognitive performance following ECT in the Asian context. @*Methods@#This review systematically identified studies assessing ECT-related cognitive effects in PubMED, PsychINFO, The Cochrane Library, Journal of ECT and major databases in Asian countries. The search included publications from peer-reviewed journals of languages other than English. @*Results@#A total of 6,322 studies were identified; 823 were assessed for eligibility, of which 16 studies met the search criteria and were included in this review. Majority used high dose Bitemporal ECT for Depression and/or Schizophrenia. Cognitive impairment, which could occur immediate to the first ECT session, was reported in only 9 out of the 16 studies. However, deficits were observed to resolve as early as 3 weeks after the initiation of ECT. The remaining studies reported no impairment or even improvement after ECT. @*Conclusion@#There is no consistent evidence that suggests ECT causes cognitive deficits in patients, despite the widespread use of high dose Bitemporal ECT. This review suggests that Asian patients, presenting with a different psychiatric profile, may respond to high-dose Bitemporal ECT differently from Western samples.

Kleptomania: a case series

Kleptomania is an enigmatic condition and is among the very few psychiatric disorders in which crime is medicalised and used as a legal defence. The scientific literature on kleptomania is scarce. Early literature and recent studies have shown a female preponderance, with an early age of onset of stealing in people with comorbid personality disorder(s). In a retrospective review of the case notes of theft offenders who had forensic psychiatric evaluations performed in a one-year period in 2010 at the Institute of Mental Health, Singapore, we found three patients who were diagnosed with kleptomania. In this report, we describe the pertinent clinical and sociodemographic characteristics, as well as the diagnostic issues of kleptomania in relation to the three cases.

HIV-Associated Neurocognitive Disorders--An issue of Growing Importance

<p><b>INTRODUCTION</b>HIV-associated neurocognitive disorders (HAND) comprise a wide spectrum of cognitive, motor, and mood abnormalities prevalent in people living with HIV and AIDS (PLWHAs). This field of HIV medicine has gained renewed prominence in recent years with evidence contending that anti-retroviral agents with increased central nervous system (CNS) penetration may improve neurocognitive outcomes in those affected. This review aims at evaluating the available evidence and postulating further study direction in Singapore.</p><p><b>MATERIALS AND METHODS</b>A PubMed search was carried out for original articles and systematic reviews on the subject of HIV-associated neurocognitive disorders, and the results reviewed by the authors.</p><p><b>RESULTS</b>There is a growing body of evidence that HAND is not uncommon, and the advent of highly active anti-retroviral therapy has increased its prevalence by improving the prognosis of HIV infection, and hence increasing the likelihood of diagnosing of this neurocognitive condition. Screening and diagnosing HAND is important, and requires clinical suspicion as well as validated test batteries for optimal accuracy. The authors recommend strategies for detection in the local context involving stepwise targeted screening. Anti-retroviral agents with good CNS penetration and activity, as well as adjunctive neuro-rehabilitative interventions, may improve the impairments experienced by affected individuals.</p><p><b>CONCLUSION</b>Increased awareness of HAND, with earlier diagnosis and targeted, multi-disciplinary management of this challenging condition, may lead to better all-round outcomes for people living with HIV and AIDS in Singapore.</p>

Pattern of psychiatric morbidity among theft offenders remanded or referred for psychiatric evaluation and factors associated with reoffence

<p><b>INTRODUCTION</b>In Singapore, theft and related crimes constitute more than 50% of all reported crime, and are the most common offences committed by accused persons remanded to the Institute of Mental Health (IMH), Singapore. There is a need for better understanding of the forensic psychiatric aspects of such offenders. This study aimed to determine the prevalence of psychiatric disorders among theft offenders remanded or referred for forensic assessment in 2010, compare the differences between first-time and repeat theft offenders, and identify the factors associated with reoffence.</p><p><b>METHODS</b>Forensic evaluations of inpatient and outpatient theft offenders that were conducted at IMH in the year 2010 were retrieved and reviewed. The sociodemographic and clinical data of first-time and repeat theft offenders were collected and compared using Student's t-test and chi-square test for continuous and categorical variables, respectively. Multivariate regression was used to identify the factors that were predictive of repeat offence.</p><p><b>RESULTS</b>Overall, 10% of offenders had no mental illness. Substance use disorders, mood disorders and psychotic disorders were the most common diagnoses. Psychotic disorders were significantly less common in repeat offenders. Repeat offenders also tended to have a history of conduct problems in childhood. Noncompliance with psychiatric treatment was positively associated with repeat offence, while psychotic disorders were negatively associated.</p><p><b>CONCLUSION</b>The pattern of psychiatric morbidity among theft offenders in Singapore has changed over the last ten years. Kleptomania remains rare. Significant differences between first-time and repeat offenders have implications on the treatment, follow-up and rehabilitation of theft offenders in Singapore.</p>
