Alzheimers causes days of murders and then a suicide?
Don’t know about that one.
The link between repeated traumas to the brain and violent behavoir is a fairly new concept. I recall a case involving a former NFL player who went on a crime binge, he was in his 30’s but his brain looked like it belonged to someone in their 70’s suffering from dementia.
Who knows...maybe if more of the geezers with Alzheimers had the testosterone levels and muscle mass of younger men...younger men who are perhaps taking in large amounts of exegenous testosterone...you’d see more “Grandpa got a rifle and he went to the mall” stories
