ASEAN Journal of Psychiatry 2017;18(2):82-93
Objective: This review summarises the existing evidence on the effects that recreational and medical use of cannabis and cannabinoids have on cognitive performance.
Methods: Databases (PubMed, Medline, and Google Scholar) were searched from inception to March 2017 by adopting the following key terms: dronabinol, nabilone, nabiximols, cannabis, marijuana, cognition, neurology, and neuropsychology. A total of 94 documents, including reviews, preclinical and clinical studies, industrial and government agencies reports were included in this review.
Results: We found that recreational use of cannabis doubles the risk of a fatal traffic accident by impairing attention and lengthening reaction time. Short-term use lowers performance in working memory, attention, executive functions and visual perception tasks. Chronic recreational use in adolescents also doubles the risk of early school-leaving, cognitive impairment and psychoses in adulthood. Adverse effects of cannabis-based medication – dronabinol, nabiximol and nabilone – and ingestion/inhalation of marijuana allowed for medical use include dizziness, drowsiness and short-term memory impairment.
Conclusion: Cannabis consumption is associated with significant impairments in a range of cognitive abilities. Of particular concern, early and chronic exposure to cannabis, especially in the adolescence, seems to be associated with irreversible cognitive impairments.

Objective: This study was aimed to determine the prevalence of anxiety and depressive symptoms , to examine their association with health-related quality of life (HRQoL) profiles and to determine the predictors on overall HRQoL. Methods: This was a cross-sectional study conducted in Hospital Sultanah Nur Zahirah, Kuala Terengganu, Malaysia. The Malay Hospital Anxiety and Depression Scale (HADS) and McGill Quality of Life Questionnaire (MMQoL) were administered to a sample of 150 cancer patients (mean age = 50.4 years). Chi-square test, correlation and multiple regression were utilised for data analysis. Results: The prevalence for mild anxiety and depressive symptoms was 30.7% and 23.3% respectively. The HADS-A correlated strongest with Total MMQoL Score (r = - 0.578) and Psychological Well-Being (r = -0.526). Only HADS-A (beta = - 0.486), and HADS-D (beta = -0.173) were significant in predicting overall health-related quality of life. Conclusion: Findings in our study indicated that the prevalence of anxiety and depressive symptoms in Terengganu cancer patients are moderate. If anxiety and depression are identified and treated, health-related quality of life among oncology patients appropriately could significantly be improved.

Objective: The study aimed to compare the efficacy and tolerability of oral risperidone and oral clonazepam with intramuscular haloperidol and oral clonazepam in Filipino patients with acute psychotic agitation. Methods: This study used a prospective randomized design targeting patients who were referred to the emergency department or hospital inpatients exhibiting both psychosis and agitation. Patients were randomized into oral risperidone group or intramuscular haloperidol group. Both groups received oral clonazepam as part of treatment. Patients were observed for 24 hours. The main efficacy parameter was the PANSS agitation cluster score. Other parameters were total PANSS, other PANSS subscale scores, time and incidence of additional clonazepam usage. The safety parameter measured as incidence of adverse events. Results: There were 99 subjects enrolled in the study: 49 in the oral risperidone arm and 50 in the intramuscular haloperidol arm. There were significant reductions in the mean PANSS agitation cluster scores for both groups: -7.6+4.7 for oral risperidone group (p<0.0001) and -6.7+5.0 for intramuscular haloperidol group (p<0.0001). There was no statistical difference observed in the mean change in PANSS agitation cluster scores among the two groups (p=0.3928). Similar trends were observed in the total PANSS and other subscale scores. The incidence of additional clonazepam use is numerically higher in the oral risperidone arm than the intramuscular haloperidol arm (33% vs. 20%), but the difference did not attain statistical significance (p=0.1370). At the end of the study, 17 (33 %) and 18 (36%) of patients in the risperidone and haloperidol groups experienced varying degrees of sedation. No serious adverse event was reported. Conclusion: Oral risperidone is comparable to intramuscular haloperidol in the treatment of acute psychotic agitation in terms of efficacy and safety.

Objective: To investigate the prevalence of Female Orgasmic Dysfunction (FOD) focusing on
the orgasm domain among female patients attending PPUKM Psychiatric clinic. To compare the
prevalence of orgasmic dysfunction between female patients on Escitalopram and on Fluoxetine
therapy. Methods: A validated questionnaire for sexual function was used to assess orgasmic
function. A total of 112 women aged between 24 and 57 participated in this study. The orgasmic
dysfunction was compared between patients on selective serotonin reuptake inhibitors (SSRIs)
fluoxetine and escitalopram. Results: The prevalence of female orgasmic dysfunction was 58.9%
(33/56) among patients treated with Fluoxetine and 41.1% (23/56) among patients treated with
Escitalopram. However, there was no statistically significant difference between these two
treatment groups (p=0.059). The odds to have FOD among patients on higher dose of
antidepressants was found to be higher compared to those patients who were on lower dose of
antidepressants (Odds ratio 5.32, p= 0.001). Conclusion: There was no significant difference of
Female Orgasmic Dysfunction between patients on Fluoxetine and Escitalopram

Objective: Brain Fag Syndrome (BFS) is a psychiatric disorder associated with study
among African students. Among secondary school students, it affects two to four out of
every ten students. One of the consequences of this illness is early foreclosure of
education in affected students. However, clinical experience suggests that many students
have sub-threshold symptoms of brain fag and are at risk for developing brain fag
syndrome. This study aimed to develop a valid and reliable psychometric instrument that
measures brain fag syndrome propensity. Methods: External and internal expert panels as
well as a patient focus group evaluated a large pool of potential item stems gathered from
the psychological and psychiatric literature. Potential scale items were then administered
to 250 students along with a set of validating questionnaires. Final item selection was
based upon rigorous empirical criteria and the psychometric properties of the final scale
were examined. Results: A final four dimensional 20-item scale, the Brain Fag Syndrome
Propensity Scale, has a Cronbach’s alpha of 0.795, split half reliability of 0.813 for the
part 1 (10 items) and 0.585 for the part 2 (10 items), and Spearman-Brown coefficient of
0.557. The intrinsic validity yielded a coefficient of 0.892. Conclusion: The current
results indicate the BFPS has an excellent internal consistency as well as good content
and concurrent validity and should have significant utility as a brief, valid measure of
propensity to develop brain fag syndrome or sub-threshold cases of BFS.

Objective: Cognitive Behaviour Therapy (CBT) for depression is popular in Western countries. In the context of Malaysia, CBT has been applied as an individual session in a clinical setting. However, there is limited research in the area of group CBT for depression among Malays. The aim of this study is to investigate the effectiveness of Group Cognitive Behavioural Therapy (GCBT) in reducing the negative cognitions that are related to depression in a group of Malay patients. Methods: One hundred and thirteen patients, diagnosed with depression, were randomly allocated to either a Treatment As Usual (TAU) group (n = 55), or a TAU plus GCBT group (n = 58). All participants completed two questionnaires that measured maladaptive cognitions at pre-treatment, midway through treatment, post-treatment (week 4), and at follow-ups after three (week 16) and six months (week 28). Results: The TAU+GCBT patients improved significantly more, and at a faster rate, than the TAU group; which showed minimal improvement. The effect size (Cohen’s d) of the treatment group was 0.93 and 96.55% of the treatment group achieved a clinically significant change. Conclusions: The findings suggest that GCBT, when used in addition to the TAU, is effective in reducing negative thoughts and maladaptive attitudes of Malaysian patients suffering from depression.
10.Effects of A Brief Stress Reduction Intervention On Medical Students' Depression, Anxiety And Stress Level During Stressful Period
ASEAN Journal of Psychiatry 2011;12(1):1-14
Objective: The objective of this study was to evaluate whether students exposed to a brief stress reduction intervention would have lesser stress, anxiety and depression levels compared to their non-exposed classmates during stressful events. Methods: The Ex Post Facto design was applied in this study. Students who were exposed and not exposed to a brief stress reduction intervention were surveyed during a continuous examination and during the final examination. The Depression Anxiety Stress Scales (DASS) was used to examine effects on anxiety, stress, and depression levels. Results: The exposed students statistically had lower anxiety and depression scores than the non-exposed students during the stressful period. Reduction of stress, anxiety and depression scores was sustained during the stressful period. Conclusion: The significant reduction of anxiety and depression scores suggested that brief intervention was effective in the enhancement of the psychological wellbeing of exposed medical students during stressful period.
