At a time when the mental health difficulties/disorders of the elderly are coming to the fore of many practitioners' patient rosters, naming and treating those problems is still too often handled as an art as much as a science. Inconsistent practices based on clinical experience and intuition rather than hard scientific evidence of efficacy have for too long been the basis of much treatment. Evidence-based practices help to alleviate some of the confusion, allowing the practitioner to develop quality practice guidelines that can be applied to the client, identify appropriate literature that can be shared with the client, communicate with other professionals from a knowledge-guided frame of reference, and continue a process of self-learning that results in the best possible treatment for clients.
