Dementia

Dementia is not a specific disease. It is a descriptive term for a collection of symptoms that can be caused by a number of disorders that affect the brain. People with dementia have significantly impaired intellectual functioning that interferes with normal activities and relationships.

What Causes Dementia?

Dementia occurs due to loss of brain function that occurs with certain diseases. It can affect several brain functions such as memory, thinking, language, planning, behavior and judgement. Dementias are usually progressive and worsen with time. They usually are degenerative and non reversible.

Can diet alone slow brain aging? Scientists say evidence is still too weak

Researchers reviewing evidence in the Annual Review of Nutrition find that healthy dietary patterns may support brain aging, but caution that scientific enthusiasm currently outpaces solid proof. Multidomain strategies combining diet with exercise, cognitive training, and vascular health show greater promise.

Computational approach provides insight into neural progenitor cells and their role in brain disorders

For much of the 20th century it was thought that the adult brain was incapable of regeneration. This view has since shifted dramatically and neurogenesis – the birth of new neurons – is now a widely accepted phenomenon in the adult brain, offering promising avenues for treating many neurological conditions.
