Twice daily electrical stimulation may boost mental processes in Alzheimer’s disease, clinical trial suggests

A new clinical trial has shown that twice-daily electrical stimulation of the brain may help to improve cognitive function in people with Alzheimer’s disease. The study, which was published in the journal General Psychiatry, found that participants who received the treatment saw significant improvements in their word recall, recall of test instructions, and word recognition.

The study involved 120 people with mild to moderate Alzheimer’s disease. Participants were randomly assigned to either receive twice-daily electrical stimulation or a sham treatment. The electrical stimulation was delivered using a device that applied a low-intensity current to the scalp.

After six weeks of treatment, participants who received the electrical stimulation showed significant improvements in their cognitive function, compared to the sham group. The improvements were maintained at a follow-up assessment six months later.

The researchers say that their findings suggest that electrical stimulation may be a promising new treatment for Alzheimer’s disease. However, they caution that more research is needed to confirm the findings and to determine the long-term effects of the treatment.

How does electrical stimulation work?

Electrical stimulation is thought to work by increasing the activity of neurons in the brain. This increased activity may help to improve the communication between neurons, which is thought to be impaired in Alzheimer’s disease.

What are the next steps?

The researchers say that they are planning to conduct a larger clinical trial to further investigate the effects of electrical stimulation on Alzheimer’s disease. They are also hoping to develop a more personalized approach to treatment, by tailoring the electrical stimulation to the individual’s specific needs.

What are the implications of this study?

If electrical stimulation is found to be an effective treatment for Alzheimer’s disease, it could have a significant impact on the lives of millions of people around the world. The treatment is non-invasive and relatively inexpensive, and it can be easily administered in a home setting.

Overall, this study is a promising step forward in the development of new treatments for Alzheimer’s disease.

The researchers say that they are hopeful that their findings will lead to new treatments that can help to improve the lives of people with Alzheimer’s disease and their families.
