High‐risk prescribing and incidence of frailty among older community‐dwelling men. Clinical Pharmacology & Therapeutics. 2012 Mar;91(3):521-8.. A case control study of approx 1.3 million people (over 65 )in 2017 found antidepressants were '''the psychotropic most strongly related to fall injuries and antipsychotics''' to hospitalizations and death. Number of psychotropics was associated with increased the risk of fall injuries, hospitalization and death in a dose–response manner. Among persons with dementia a dose–response relationship was found between number of psychotropics and mortality risk .Johnell K, Jonasdottir Bergman G, Fastbom J, Danielsson B, Borg N, Salmi P.

Some antidepressants and antipsychotics also cause [[Orthostatic Hypotension|orthostatic hypotension]]. Any drug that reduces the [[Blood Pressure|blood pressure]] or slows the heart can cause falls. Symptoms are associated with feeling faint, loss of consciousness or “legs giving way”.Darowski A and Whiting R. Cardiovascular drugs and falls. Reviews in Clinical Gerontology 2011, 21 (2), 170-179 In some patients the cause of the fall is clear. Objectively they may be hypotensive, or have a systolic drop on standing. Other patients may have normal blood pressure but have syncope or pre-syncope from carotid sinus hypersensitivity or vasovagal syndrome. Stopping cardiovascular medication reduces syncope and falls by 50%.Van der Velde N, van den Meiracker AH, Pols HA, Stricker BH, van der Cammen TJ.
