Dementia News and Research

RSS

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. They also lose their ability to solve problems and maintain emotional control, and they may experience personality changes and behavioral problems, such as agitation, delusions, and hallucinations.

Antisense Therapy Shows Promise Against Parkinson's

Parkinson's disease (PD), as well as many other neurodegenerative disorders, has shown a link between the abnormal aggregation of a protein called α-synuclein (aSyn) and neuronal death. These aggregates, known as Lewy bodies and Lewy neurites depending on their subcellular localization, can spread by continuously causing normal endogenous aSyn to misfold.

Herpes Gene Therapy Achieves 90% Viral Reduction in Pre-Clinical Studies

Researchers at Fred Hutch Cancer Center have found in pre-clinical studies that an experimental gene therapy for genital and oral herpes removed 90% or more of the infection and suppressed how much virus can be released from an infected individual, which suggests that the therapy would also reduce the spread of the virus.

New Study Sheds Light on Blood-Brain Barrier Dysfunction in Aging

The central nervous system requires a tightly controlled environment for the neurons in the brain to function properly and be able to process information. The blood-brain barrier, which is maintained by specific brain endothelial cells lining blood vessel inner walls, controls the exchange of chemicals between the neurological and circulatory systems.
