Slowing brain waves signal the first signs of dementia

American researchers are studying ways to effectively diagnose neurodegenerative diseases.A recent study has shown that people who are likely to be in the early stages of Alzheimer's disease (mild cognitive impairment) and those with a type of rare dementia (progressive loss of speech).

Researchers at the New York University School of Medicine have shown that slow brainwaves are signs of damage in areas of the brain responsible for memory and planning, where they have memory problems and thought.

"We were able to use the EEG to determine that this slowdown in electrical activity occurs in some areas that have not yet lost their brain cells but are negatively affected," said Dr. Good Meltzer, professor at the Rothman Research Institute. This means that these areas may be more sensitive to treatment because brain cells have not yet died and are not starting to be damaged. "

The team hopes to further validate the use of brain activity as a reliable health indicator for the first signs of dementia. Researchers can also develop their work on identifying effective ways to stop the development of brain disease. neurological disorders or treat early brain changes by noninvasive electrical stimulation.
