United Press International, aka UPI, reports the findings of two separate studies both of which discover things which are associated with lower risk of Alzheimer's disease. The first finds that taking Viagra, widely prescribed for erectile dysfunction, reduces the likelihood of developing the disease. The second finds that having had cataract surgery reduces the likelihood of Alzheimer's.
Both studies are correlational and need further research substantiation to determine causation, should any exist. Nevertheless, all such findings are welcome as this disease is no joke. Old age is bad enough without the additional insult of mental deterioration. Hat tip to Instapundit for the link.
