Sudden cardiac death and stroke in TBI patients taking antipsychotics
It is generally acknowledged that antipsychotic drugs can slow cognitive and motor recovery in patients with traumatic brain injury. Recent studies have shown that antipsychotic use is also associated with an increased risk of sudden cardiac death and stroke.
A commentary by Mel Glenn, MD was recently published in the Journal of Cognitive Rehabilitation, which stated that "Each of the 6 frequently used drugs (haloperidol, thioridazine, clozapine, quetiapine, olanzapine, and risperidone) had an increased rate" ratio of sudden cardiac death and stroke. It was noted that atypical antipsychotics, such as risperidone, carry an even greater risk than typical antipsychotics. Additionally, people aged 70-74 had a risk rate 10 times that of people aged 30-34.
It is not uncommon for a traumatic brain injury patient to be given antipsychotics as a behavioral intervention. Unfortunately, symptoms such as memory impairment, visual-spatial disorders, and changes in personality can be mistaken as symptoms of psychosis, and clinicians may often dispense an antipsychotic as a short- or long-term treatment. Although there may be a place for the use of antipsychotics in a crisis situation, alternative therapies should be considered before continuing treatment in the long-term.
