Microscopic brain tissue changes have been described in Alzheimer's disease since Alois Alzheimer first reported them in 1906. The two principal changes are senile or neuritic plaques (chemical deposits consisting of degenerating nerve cells combined with a form of protein called beta amyloid) and neurofibrillary tangles (malformations within nerve cells). The brains of Alzheimer's disease patients of all ages reveal these findings on autopsy examination.
The plaques found in the brains of people with Alzheimer's disease appear to be made, in part, from protein molecules--amyloid precursor protein (APP)--that normally are essential components of the brain. Plaques are made when an enzyme snips APP apart at a specific place and then leaves the fragments--beta amyloid--in brain tissue where they come together in abnormal deposits. It has not as yet been definitely determined how neurofibrillary tangles are formed. Read more: examiner.com
Certain diets influence certain behaviors
Different types of food stimulate different regions of the brain so significantly they influence how we behave, a U.S. professor has claimed. Read more: myfoxatlanta.com
