Arteriosclerosis is a disease of aging producing a progressive hardening and narrowing of brain arteries.

Arteriosclerosis, which cause is unknown, develops randomly in different areas of the brain.

Arteriosclerosis of the cerebral arteries is a general phenomenon associated with dementia.

Depending on the location of the vascular involvement generally associated with dementia, the symptoms will be those of "Alzheimer's disease", vascular dementia, or "Parkinson's disease".

Different areas of the brain can be affected. In the beginning, the destruction of the brain involves specific regions.

For example, "Alzheimer's disease" is a form of dementia characterized by progressive memory loss overtime associated with secondary lesions as senile plates, amyloid deposits, and immune reactions. This pathology affects the amygadala and hippocampus in the depths of the brain.

For example, tremors characterize "Parkinson's disease".This pathology affects the substantia nigra that  is a basal ganglia structure located in the midbrain.

Over time, arteriosclerosis destroys the entire brain.

 Destruction of the brain starts around forty and will reach everybody with time. Thus, the prevention of dementia must start around forty.
