Attempts to make political points by bringing up DoD spending on erectile dysfunction medication don't tell the whole story. Which may sound baffling - given the drug is to this point used in the primary only for treating erectile dysfunction and pulmonary hypertension - within the research group, there have been already indicators the sildenafil compound might have other kinds of health benefits, given its interactions with the amyloid and tau proteins implicated in Alzheimer's pathology. Nonetheless, the researchers say the correlation shown right here - in addition to different indicators in the research - is sufficient to determine sildenafil as a promising candidate drug for Alzheimer's illness, the viability of which will be explored in future randomized clinical trials designed to check whether causality does indeed exist.
