American researchers of Harvard University gave the answer to the question that the first signals about the developing human Alzheimer’s disease. This symptom, as demonstrated by their work manifests before the obvious deterioration of mental abilities.

But the researchers discovered differential emotional health takes place even earlier and can serve as a method of early diagnosis of the disease, they said.

Such a change in the person’s mood correlates with the beginning of the process of accumulation of amyloid plaques in the brain. This conclusion was made by experts according to the results of monitoring over 300 patients over five years.
