In a study from Northwell Health in Glen Oaks, scientists found pre-COVID-19 psychotropic medication use is associated with higher risk for incident dementia following hospitalization for COVID-19 (post-COVID dementia) in older adults.
Previous research has shown that people 65 and older who contracted COVID were nearly 70% more likely overall to be diagnosed with Alzheimer’s within a year of their infection.
The elderly fared even worse, with the risk of Alzheimer’s doubling in COVID patients who were over 85.
There are five main types of psychotropic medications: antidepressants, anti-anxiety medications, stimulants, antipsychotics, and mood stabilizers. Antidepressants are used to treat depression.
They examined the association between pre-COVID psychotropic medication use and one-year incidence of dementia in 1,755 older people (≥65 years) hospitalized with COVID-19.
The researchers found that the one-year incidence of post-COVID dementia was 12.7%.
Pre-COVID psychotropic medications and delirium were strongly linked to a higher one-year incidence of post-COVID dementia.
When the team’s analysis focused on 423 patients with at least one neurological or psychiatric diagnosis at the time of COVID-19 admission, the association between psychotropic medications and dementia risk remained robust.
The strongest associations with post-COVID dementia across different drug classes were seen for antipsychotics and mood stabilizers/anticonvulsants.
The team says it is important to note that this study is no way recommending people should stop taking antipsychotics, but simply that clinicians need to factor in a patient’s medication history while considering post-COVID aftereffects.
If you care about COVID, please read studies about Vitamin D deficiency linked to severe COVID-19, and Mediterranean diets could help people recover after COVID infection.

The study was conducted by Yun Freudenberg-Hua et al and published in Frontiers in Medicine.
