A study published in Neurology has shown a link between the use of α-1 blockers, a type of drug used to treat urinary symptoms in men with an enlarged prostate, and a lower risk of developing dementia with Lewy bodies (DBL), with a risk reduction of about 40% when compared with men taking other prostate drugs.

These findings align with a study published in the Jama Network in 2021, which suggested that the same type of drugs also lower the risk of developing Parkinson’s disease, which has similarities to DBL.
