American doctors have suggested that Alzheimer's is actually contagious, reports MedicalNeews Today.

In their view, brain damage in Alzheimer's disease has much in common with prion diseases, such as mad cow disease. Prions are a special class of infections that cause severe damage to the central nervous system. Diseases of this type were discovered recently, among them - spongiform encephalopathy and mad cow disease.

Until now, none of the theories of the onset of Alzheimer's disease suggested its infectious nature, however, new research data give new arguments in favor of the infectious nature of dementia.
