Sleep disturbance is common in the elderly and is frequently undiagnosed. It has been estimated that 75% of adults >65 years of age has sleep disturbance and 30% of them has insomnia. The classification of insomnia has less significance in the older adults as the subtypes demonstrate significant overlap and usually treatment of the underlying disorder does not solve the problem or cure it. The elderly has multiple comorbidities and polypharmacy with a myriad of cause for insomnia. A comprehensive medical and psychiatric history together with a complete physical examination and mental state examination should be done in the evaluation of the older patient. Behavioural therapy with sleep hygiene education should be the initial treatment together with the treatment of the contributing physical and psychiatric conditions. Referral to an expert for cognitive behavioural therapy or multicomponent therapy may be necessary if the initial therapy failed to produce any improvement. If medications are needed it can be combined with behavioural therapy. Medication used should be the lowest effective dose and prescribed for short-term use of not more than 4 weeks. Medications used need to be discontinued gradually and one needs to be mindful of rebound insomnia upon withdrawal. Wherever possible, it will be ideal to avoid benzodiazepines and other sedative hypnotics as first choice for insomnia. Over the counter sleep aids which usually contain antihistamines may not be good choices as they carry significant risk of adverse events and drug interactions. Currently the safest medications for use in the elderly includes the Z-drugs (zolpidem, zopiclone), melatonin and low dose tricyclic antidepressant Doxepin.

To highlight the diagnostic challenges in diagnosing a patient with schizoaffective disorder under DSM-IV-TR and to evaluate the effectiveness of changes in DSM-V in addressing these issues. Methods: We present the evolution of the diagnosis from its inception, outline its complex nosology, review the diagnostic difficulties under DSM-IV-TR and critique the proposed changes made in DSM-V. Results: A complex nosology, varied thresholds of diagnosis under DSM-IV-TR, and the inherent difficulty in obtaining a detailed longitudinal history from a patient contribute to the challenge of diagnosing a patient with schizoaffective disorder. Changes in DSM-V attempt to increase the reliability of the diagnosis by specifying and raising temporal thresholds, moving the time of disease observation away from a single episode but towards the lifetime of illness. Conclusion: Changes made in DSM-V only address a small part of the difficulties raised and clinicians will continue to face challenges in diagnosing schizoaffective disorder under DSM-V. However, there might still be value in the proposed changes under DSM-V

Objective: This paper aims to explore the possibility of using motivational interviewing (MI) as a therapy for insomnia patients. Methods: We reviewed the current practice guidelines for insomnia, and noted the issues pertaining to types of treatment, notably CBT-I. We also reviewed some studies which seem to suggest that MI treats insomnia. Results: MI is a proven technique for other psychiatric illnesses. There are currently not many studies done evaluating the efficacy of MI on insomnia. Of those published studies, they are either underpowered to draw any firm conclusions, or it is limited to a particular age group. Conclusion: There seems to be promise in the area of MI on insomnia. Given the paucity of data in this area, more research with bigger group of study participants are needed to fully conclude the effectiveness of this treatment.

Objective: This case illustrates how a patient with medically unexplained symptoms was “cured” using symbolic healing rituals of Christianity and traditional Malay black magic. Method: We report a case of a 49-year-old lady who presented with unexplainable weight loss and dysphagia despite extensive outpatient and inpatient medical investigations. She later attributed these symptoms to a “curse” by a Boyanese man with whom she had disagreements. After catharsis with a Roman Catholic priest and cleansing with a Bomoh (Malay witch doctor), the patient’s health improved. Results: We believe this patient had a conversion disorder due to recent multiple stressors in her life and she attributed her symptoms to the “curse” inflicted to her. The symbolic healing rituals by the Catholic priest and Bomoh “cured” her of her illness which concurred with the patient’s own beliefs for her illness. Conclusion: This article illustrates the importance of the physician being familiar with various local traditional beliefs, and how the interplay between various different religions and customs can come together to treat medically unexplained symptoms in a country like Singapore.
