The article below addresses this issue in Canada, and offers some intriguing statistics about the numbers of dementia patients who are being treated with anti-psychotic drugs, primarily to reduce aggressive behaviours and agitation, as well as the number that actually seem to improve on the medication. The article also delves into the factors that contribute to the reliance on these medications, particularly in long-term care facilities, and the side effects of anti-psychotics, in addition to suggesting some non-pharmacological alternatives that may be more safe and effective.
