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.
A team of researchers have discovered that a gut hormone, called ghrelin, is a crucial regulator of new nerve cells that form in the adult brain.
A metabolite produced following consumption of dietary soy may decrease a key risk factor for dementia--with the help of the right bacteria, according to a new discovery led by researchers at the University of Pittsburgh Graduate School of Public Health.
Variations in a gene that regulates dopamine levels in the brain may influence the mobility of elderly and frail adults, according to new research from the University of Pittsburgh Graduate School of Public Health.
A new, rare genetic form of dementia has been discovered by a team of Penn Medicine researchers. This discovery also sheds light on a new pathway that leads to protein build up in the brain -- which causes this newly discovered disease, as well as related neurodegenerative diseases like Alzheimer's Disease -- that could be targeted for new therapies. The study was published today in Science.
New treatments for metabolic diseases, such as type 2 diabetes, could emerge from a study of how a single enzyme controls the growth of the pancreatic cells that produce insulin.
More than 18 percent of U.S. adults do not know whether they will have enough to eat from day to day, and the numbers are worse for Hispanics, Blacks, people with obesity, and women, a new report shows.
Deposits of a protein called "Medin", which manifest in virtually all older adults, reduce the elasticity of blood vessels during aging and hence may be a risk factor for vascular dementia.
A congenital disorder of the fat metabolism can apparently cause chronic hyperreaction of the immune system. This is the conclusion reached by researchers from the University of Bonn in a recent study.
Researchers have investigated the function of a complex mesh of muscle fibers that line the inner surface of the heart.
Results from a recent clinical trial indicate that for older adults with advanced cancer, initiating aspirin may increase their risk of disease progression and early death.
A hospital nurse for 33 years, Nanette Miller would call her husband Frank at the end of each shift to let him know she was coming home.
A world first clinical study of the gut microbiome in people with Huntington's disease (HD) has found that it is not just a disease of the brain, but also of the body.
Two decades or more before symptoms arise, plaques of a sticky protein called amyloid begin forming in the brains of people later diagnosed with Alzheimer's disease.
AZoLifeSciences talks to Dr. Shane Liddelow about their research into discovering the critical role of astrocytes in neurodegenerative diseases like glaucoma.
A UB study published in the journal Neurotherapeutics has validated a new pharmacological target for Alzheimer's disease.
Genes and cardiovascular health each contribute in an additive way to a person's risk of dementia, U.S. researchers including Sudha Seshadri, MD, and Claudia Satizabal, PhD, of The University of Texas Health Science Center at San Antonio (UT Health San Antonio) reported July 20 in the journal Neurology.
Genes linked to ageing that could help explain why some people age at different rates to others has been identified by scientists.
Scientists from Trinity College Dublin have discovered a new link between impaired brain energy metabolism and delirium - a disorienting and distressing disorder particularly common in the elderly and one that is currently occurring in a large proportion of patients hospitalized with COVID-19.
Across the globe, approximately 50 million people are living with dementia. The two most common forms are Alzheimer's disease and frontotemporal lobar degeneration (FTLD), which develop when neurons in specific parts of the brain stop functioning - triggering memory loss and other behavioral or personality changes.
Neurons in the brains of such people are being depleted gradually and inevitably, resulting in the characteristic loss of cognitive function and memory.
