A study indicates a history of concussion, including at least one momentary loss of consciousness, may increase the risk of Alzheimer’s disease by contributing to the build-up of Alzheimer’s-associated plaques in the brain.
 
Researchers at Mayo Clinic in Rochester, Minnesota conducted brain scans of 448 people without any thinking or memory problems and 141 individuals with mild cognitive difficulties. All the participants were 70 or older.
 
Each group was asked whether they had experienced a brain injury that involved a temporary loss of consciousness or memory.
 
Seventeen percent of the cognitively normal participants said they had had a brain injury and 18 percent of those with memory and thinking difficulties reported suffering a concussion or head trauma.
 
The study found no differences in brain imaging measurements among the cognitively healthy individuals, whether or not they had experienced a brain injury. However, in those with mild cognitive impairment and a history of concussion, the scans revealed an 18 percent higher level of amyloid plaques. Those protein deposits in the brain are the hallmark of Alzheimer’s disease.
 
Lead researcher Michelle Mielke calls the findings interesting, suggesting there may be a relationship between concussion and Alzheimer’s disease.
 
An article on the findings is published in the journal Neurology.

I agree that it's a little vague. I think we all know that head trauma is a major risk factor. Tell us something we don't know and something useful.

This is rather vague isn't it? Don't you think they would have figured this out by now whether a person had a head injury or not caused Alzheimer!!?

My father was a professional boxer and began showing signs of dementia when he was in his 50s. He died in 1972 which at the time did not look into dementia causes as much as it is done now

My grandfather passed away from this disease WWII/Korean war veteran, he worked on the B52 Bombers to protect us. This is not on the main agenda to let people know. Hard working like myself and many more. They have tried to link this and aluminum also. People will die from cancer first. Watch what you eat and do to yourself. I have very close family members that have gone through both awful diseases and still fighting the battle. Do not let the media decide ,do it on your own to change your life ,to live a long and prosperous life

The whole article is a joke. Anyone with half a brain on their shoulders knows the FACT that this disorder is DIRECTLY LINKED to the FLUORIDE in the tap water, MERCURY in the vaccines, (including flu), and GMO in the foods. Harvard University and many other leading universities PROVE this. Any mention of that, VOA?????????? OF COURSE NOT!!!
