Prevention of psychiatric illness in the elderly, I: Path to prevention of dementia

The 14th Congress of the International Psychogeriatric Association was held in Montreal, Canada, on 1–5 September 2009 (IPA 2009 Montreal). The main theme of the congress was ‘Path to Prevention’ and several interventional studies of dementia, depression, anxiety, and psychosis in the elderly were presented and discussed at the Congress. Pharmaceutical treatment of psychiatric illnesses and patient care are important, but we are now almost at the stage of the prevention of psychiatric illnesses in the elderly. Recent progress in prevention strategies is reviewed in this editorial. The number of demented elderly has been increasing worldwide and considerable effort has gone into elucidating the pathologenesis of Alzheimer’s disease (AD) and related disorders, as well as into the development of diagnostic methods and therapeutics. The prevention, if possible, is more important than therapeutics since no one will have pain or distress and no cost will be required for therapeutics. Primary prevention of dementia is decreasing the risk of dementia in the elderly and is based on lifestyle modification. For example, exercise, leisure, and diet are important factors in the primary prevention of dementia.
