Electrical stimulation of the brain can reverse memory loss



Improved memory performance through electrical stimulation?

Especially in age, our memory gets worse and worse. Researchers have now discovered that electrical stimulation in the elderly can improve memory. After such treatment, memory is said to work as well as in people decades younger.

A new study from Northwestern University in Illinois found that electrical stimulation of a certain part of the brain in older people improves patient health Memory causes. The results of the study have been published in the English-language journal "Neurology."

Brain Electric Stimulation Improves Memory

Stimulation of a specific part of the brain in people over 64 years of age with normal age-related memory loss results in increased performance of those affected by memory increased again. The treatment worked so well that at the end of the study no difference was seen in the test results from younger healthy adults and older participants, the researchers report. The results are the latest in a wide range of medical studies that examine the benefits of electrical stimulation in the brain. The current study looked at the effects of using electric current on the brain hippocampus.

There was a significant improvement in memory performance

It was a relatively small study with only 16 substances living in the brain The ages were between 64 and 80 years old. Participants reported typical memory problems for their age. After a five-day treatment, where her brain was stimulated with light electric current for 20 minutes a day, her memory was comparable to that of younger people. The memory of the memory improved to the level that it could no longer be distinguished from the memory of younger healthy people, the authors of the study write in a press release. Thus, there was a significant improvement.

The result of young and old was equally good

Prior to the used electrical therapy, also called transcranial magnetic stimulation (TMS), participants performed 15 percent worse in memory tests as an 18 to 34 year old. Participants achieved a score of 40 percent for computer-aided data on fixed object relationships. Younger people made 55 percent in a previous survey. After electrical stimulation, both results were equally good.

Activities in the brain are controlled by electrical impulses

Transcranial magnetic stimulation increased the activity of the so-called parietal lobe that controls the hippocampus. Hippocampus affects functions such as the formation of new memories, learning and emotional control. All brain activities, including the formation and recovery of memories, are governed by electrical impulses. Canceling or reducing these electrical signals can interfere with the person's ability to create new memories or remember old ones.

Electric Power Can Sync Brain Waves

A study from Boston University released this month in the magazine "Nature Neuroscience" has shown that brain waves in older people between two parts of the brain, which control short-term memory, are sometimes not in rhythm. If certain parts of the brain, the temporal lobe and the prefrontal cortex are stimulated with electrical current, it can synchronize brain waves, potentially improving memory formation, the researchers said. Alzheimer's disease occurs when proteins accumulate in the brain and cause nerve damage. Here, the search for new ways to promote brain activity that continue to diminish in dementia patients can help restore function or slow memory loss.

Treatment also improved the memory of younger people in the short term

Last year, the researchers tested the same therapy performed on a scalp-mounted metal coil of 16 patients without any memory problems during the age of 34. Study data was used for comparison in the current study. Participants' ability to remember details in images is improved after treatment for at least 24 hours. The authors of the study are not sure how long the effects can last. But they hope that this new type of treatment can be tested on people with mild cognitive impairment, a precursor to Alzheimer's disease. (As) [19659017]
