Biological Basis for Depression and Anxiety Traced


Researchers at US San Franscisco partnered with Brazilian Biobank for Aging Studies which is based at the University of Sao Paulo to find out what causes brain degeneration resulting from Alzheimer’s. And they found out that neuropsychiatric symptoms namely anxiety, depression, anxiety, and sleep disturbances play a role in it.

They explained their findings in details in an online publication in the month of September. In it they said that this could pave the way for early detection of Alzheimer’s disease. It could also turn out to be a crucial biomarker for developing therapies that can thwart the progress of the ailment. It may prove to be useful for gauging the biological causes of psychiatric symptoms in older adults too.

Alzheimer’s is a progressive neurodegenerative condition which can be uncovered through an autopsy of the brain way ahead of the main cognitive effects are actually visible. To treat it, it is imperative to find treatments for the initial stages. This can prevent further loss in the brain tissue, thus slowing or preventing the development of dementia.

In order to develop such treatments, however, a proper examining of the biology that causes the disease in the early stages is needed. Patients need to be treated early in order to stem massive loss of neural tissue.

Several studies have uncovered relations between neuropsychiatric symptoms and anxiety, depression, and disturbed sleep – all of it eventually leading to Alzheimer’s. A few have suggested leveraging the symptoms for usage as biomarkers at the outset of the disease.
