Considerations in psychotropic treatments in dementia-can polypharmacy be avoided?

Abstract

Physicians treating demented individuals are confronted with complex clinical presentations. This complexity results from the multi-factorial nature of clinical phenomena, the aetiologies of these phenomena, which differ from similar symptoms in younger populations, limited physiological reserves and the multiple co-morbidities and medications. This intricacy is well exemplified within the clinical presentation and management of psychological and behavioural symptoms of dementia. The latter are associated with a poor quality of life, increased burden for both patient and caregivers. A further challenge and source for frustration is the fact that many of the medications used to treat cognitive and behavioural symptoms of dementia are only marginally effective or not effective at all, on the one hand, and associated with increased risk for morbidity and mortality on the other hand. In the present review, we discuss these factors in the context of polypharmacy and suggest further clinical and research strategies that may enable more accurate and less harmful therapeutic strategies. © 2013 Published by Cambridge University Press.
