EEG detects the onset of Alzheimer’s

The search for methods of early diagnosis of neurodegenerative disorders has allowed scientists from the Centre for geriatric care Baycrest in Canada to make the discovery that EEG technique allows to detect the onset of Alzheimer’s and detect the disease even before the development. EEG is a method of research of electric activity of the brain, and scientists have found that tracking brain activity of a person quite accurately defines the beginning of the disease.

A study of canadian experts has shown that people with mild cognitive impairment, and patients with primary progressive aphasia (form of dementia) are parameters of the EEG sluggish brain waves at rest compared to healthy people. The study of brain activity allows you to capture quite subtle damage in areas of the brain responsible for memory and planning, said the authors.

Scientists believe that a decrease in brain activity and sluggish brain waves, captured using an EEG, is a “reliable biomarker of incipient dementia”. The researchers noted that a similar slowing of electrical activity in certain areas of the brain occurs at a stage when brain structures still do not lose neurons. This can occur only slight trouble thinking and remembering. But if the EEG detects the slowing of brain oscillations, it predicts serious violations until the onset of Alzheimer’s disease, experts believe.

The study showed that people who are prone to neurodegeneration, even in young age you can capture the calming brain waves. In older, but healthy people EEG recorded “fast” wave.
