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.

Transcriptomic analysis of Alzheimer's patients reveals early organelle dysfunction in astrocytes

An international group of researchers led by the UAB analyzed the genes that are expressed in neurons and astrocytes based on data from 800 individuals and compared what happens in Alzheimer's patients and in people without diagnosed dementia.

Study identifies two types of brain cells that play a key role in creating memories

In a study led by Cedars-Sinai, researchers have discovered two types of brain cells that play a key role in dividing continuous human experience into distinct segments that can be recalled later.

Research points to a common thread linking diverse neurodegenerative diseases

Take a cell-deep tour of a brain afflicted with Alzheimer's disease, and you will find minuscule clumps of protein that seem suspicious. Ever since the 1980s, when neuroscientists began identifying these protein tangles, researchers have discovered that other brain diseases have their own tangled-protein signatures.

Novel molecular pathway shared by ALS and frontotemporal dementia identified

Scientists from two independent research teams have discovered how the mislocalization of a protein, known as TDP-43, alters the genetic instructions for UNC13A, providing a possible therapeutic target that could also have implications in treating amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and other forms of dementia.

New study uncovers potential driver of Parkinson’s disease

Parkinson's disease may be driven in part by cell stress-related biochemical events that disrupt a key cellular cleanup system, leading to the spread of harmful protein aggregates in the brain, according to a new study from scientists at Scripps Research.

UCI biologists discover how a gene variant protects against Alzheimer's disease

While the word "mutation" may conjure up alarming notions, a mutation in brain immune cells serves a positive role in protecting people against Alzheimer's disease.

Scientists use genetically informed brain atlases to identify hundreds of genomic loci

An international team of scientists has used atlases of the human brain informed by genetics to identify hundreds of genomic loci. Loci is plural for locus, and in genetics indicates the physical location of a gene or variant on a chromosome.

Flavanols enhance browning of adipose tissue by activating the sympathetic nervous system

In cold conditions, brown adipose tissue (BAT) or brown fat generates heat to keep the body warm. Compared with white adipose tissue, BAT has more mitochondria-;subcellular organelles associated with energy production-;which allows it to burn calories and produce heat by activating the mitochondrial uncoupling protein 1 (Ucp-1).

Researchers catalog the complete cells that form the blood vessels of the human brain

Researchers at UC San Francisco have cataloged all of the cells that make up the blood vessels in the human brain, as well as their positions and the genes produced.

Stanford study reveals how ribosomes may contribute to age-related diseases

Aging leads to a decline in cellular fitness and loss of optimal protein function. Many age-related ailments, including Alzheimer's and Parkinson's diseases, are caused by protein aggregation, a result of errors in protein folding.
