Sleep disturbance is common in the elderly and is frequently undiagnosed. It has been estimated that 75 percent of adults >65 years of age has sleep disturbance and 30 percent 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 poly pharmacy 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 shortterm use of not more than four weeks. Medications used need to be discontinued gradually and one needs to be mindful of rebound insomnia upon withdrawal. Whenever 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.
