Association of Terazosin, Doxazosin, or Alfuzosin Use and Risk of Dementia With Lewy Bodies in Men

Terazosin, doxazosin, and alfuzosin (Tz/Dz/Az) are α-1 adrenergic receptor antagonists that also bind to and activate a key adenosine triphosphate (ATP)-producing enzyme in glycolysis. It is hypothesized that the increase in energy availability in the brain may slow or prevent neurodegeneration, potentially by reducing the accumulation of alpha-synuclein. Recent work has suggested a potentially neuroprotective effect of the use of Tz/Dz/Az in Parkinson disease in both animal and human studies. We investigated the neuroprotective effects of Tz/Dz/Az in a closely related disease, dementia with Lewy bodies (DLB).
