New Delhi: In a new development in the field of Alzheimer's disease, scientists have devised a method that promises not only to help in early diagnosis of the debilitating condition but also improve quality of life of those affected.

Early diagnosis of Alzheimer's disease, a brain disorder that results in memory loss and cognitive changes, allows treatment that helps slow its progression.

Dr Pravat K Mandal, additional professor (Scientist V) at the National Brain Research Centre in collaboration with AIIMS used Magnetic Resonance Imaging (MRI) technique that can track an important component in the brain -- Glutathione (GSH) -- that can indicate if a person stands the risk of suffering from the disease and thus, help in early diagnosis by checking GSH level in selective brain region.

Dr Mandal said, "The study revealed that Glutathione which acts like the brain cell's security guard is substantially very less in Alzheimer's patients.

"Not only this, those undergoing treatment for Alzheimer's disease can be benefited by this study to test the efficacy of any medication by monitoring GSH level using this technique." Alzheimer's disease affects millions of people, mostly over 55 years of age.

Symptoms of Alzheimer’s disease usually develop slowly and gradually worsen over time, progressing from mild forgetfulness to widespread brain impairment.

As critical cells die, drastic personality loss occurs and body systems fail.
