Ashwagandha May Reduce Memory Loss And Alzheimers Symptoms

Although the work is preliminary, researchers at the National Brain Research Centre (NBRC) say they have shown that the herb ashwagandha may reverse memory loss in individuals with Alzheimer’s disease. Their findings were made in mice modified to have Alzheimer’s, a commonly used way to study the disease.

Alzheimer’s disease is a progressive brain disease and the most common type of dementia. One characteristic of the disease is the accumulation of protein deposits (beta amyloid) as plaque in the brain. Beta amyloid is the primary component of amyloid plaque. Much of the prevention and treatment research has focused on ways to eliminate this plaque.

National Brain Research Centre neuroscientist Vijayalakshmi Ravindranath and his team administered an extract of ashwagandha root daily for 30 days to two groups of genetically modified mice with Alzheimer’s disease: one midde-aged group and one older group. At the start of the study, the mice were neither able to learn nor retain any learning.

After 20 days of treatment, the mice showed improvement in cognitive abilities, and by day 30, they behaved normally. The researchers also noted a reduction in the amount of amyloid plaque. The researchers noted that ashwagandha doesn’t interact directly on the brain. Instead, it enhances a protein found in the liver, which in turn enters the blood and works like a sponge to extract amyloid from the brain.

Ashwagandha has a long tradition in Ayurvedic medicine as a treatment for various conditions, including arthritis, respiratory ailments, inflammation, gastrointestinal disorders, and in recent times, lab studies have suggested it has some anticancer potential.
