Seemingly harmless fluid-filled spaces around the cerebral small vessels, commonly seen on brain MRIs in older adults, are now thought to be associated with more compromised cognitive skills, according to a Vanderbilt University Medical Center study published in Neurology. The new findings challenge longstanding beliefs that these areas — known as perivascular spaces — are

Using strong and targeted but noninvasive magnets at specific sites in the brains of people with and without mild learning and memory problems, Johns Hopkins researchers report they were able to detect differences in the concentrations of brain chemicals that transmit messages between neurons. The strength of these magnetic fields allows the researchers to measure

Dementia occurs when nerve cells in a person’s brain stop working. Although it typically happens in older people, it is not an inevitable part of aging. The brain’s natural deterioration happens to everyone as they grow older, but it occurs more quickly in people with dementia. There are many different types of dementia. According to

Typically, damaged nerve fibres of the central nervous system (CNS) in the brain, the optic nerve and spinal cord don’t have the ability to regenerate. One of the pivotal reasons is that nerve fibres don’t produce any proteins that are necessary for their regeneration, or that they don’t produce enough of those proteins. The team

The worldwide map of dementia: Scientists reveal the memory-robbing disorder has skyrocketed by 117% over just 26 years as the global population continues to live longer Experts warn rates will double from 43.8million in 2016 to 100million by 2050 Turkey has the most cases, followed by Brazil, and Nigeria and Ghana the least  As well

Orange juice protects against dementia? Orange juice is a healthy drink that is also very tasty. Therefore, it is not surprising that many people prefer to consume regular orange juice. Researchers found now, that when people drink every day a glass of orange juice, this seems to reduce the risk for the development of dementia

In a Geriatrics & Gerontology International study of 51 individuals living with dementia who attended community-based adult day health centers, behavioral observations of a music intervention showed a positive change in mood and a decrease in agitation. Participants demonstrated significant increases in joy, eye contact, eye movement, being engaged, and talkativeness, and a decrease in

A ‘brain training’ app developed at the University of Cambridge could help people who suffer from obsessive compulsive disorder (OCD) manage their symptoms, which may typically include excessive handwashing and contamination fears. In a study published in the journal Scientific Reports, Baland Jalal and Professor Barbara Sahakian from the Department of Psychiatry, show how just

Women who suffer pre-eclampsia during pregnancy are three-and-a-half times more likely to get dementia Pre-eclampsia reduces blood flow to a woman’s brain, leading to dementia Reduced blood flow in the placenta restricts oxygen and nutrients to the baby Leading cause of stillbirth and one of the biggest causes of maternal death  e-mail View comments Women

In a breakthrough human study, anti-oxidant, glutathione (GSH), which protects the brain from stress, has been found to be significantly depleted in Alzheimer’s patients compared to normal subjects. As GSH is a very important anti-oxidant that protects the brain from free radicals, the findings give us another measure to use when diagnosing potential for the

As though suffering a stroke isn’t bad enough, a new study has shown that people who survive one are twice as likely to develop dementia. Data from 3.2 million people – the largest study ever done on stroke and dementia – suggests the damage done by a stroke seriously raises the risk of getting dementia.

Lack of estrogen may play a role in the development of anxiety and memory problems, according to a new rodent study. The findings will be presented today at the American Physiological Society’s (APS) Cardiovascular, Renal and Metabolic Diseases: Sex-Specific Implications for Physiology conference in Knoxville, Tenn. Estrogen, the primary female sex hormone, regulates the female

(HealthDay)—The risk of death from dangerously low blood sugar is much higher among seniors who have both diabetes and dementia than those with diabetes alone, a new study finds. Researchers analyzed data from nearly 20,000 people aged 65 and older with type 1 or type 2 diabetes who were followed for up to five years

MONDAY, Sept. 24, 2018 — Multiple pathways account for the age-related increases in dementia risk, according to a study recently published in the Annals of Neurology. Melinda C. Power, Sc.D., from the George Washington University Milken Institute School of Public Health in Washington, D.C., and colleagues used data from 1,362 autopsied participants of three community-based

Zombie cells are the ones that can’t die but are equally unable to perform the functions of a normal cell. These zombie, or senescent, cells are implicated in a number of age-related diseases. And with a new letter in Nature, Mayo Clinic researchers have expanded that list. In a mouse model of brain disease, scientists

Researchers at King’s College London have discovered a vicious feedback loop underlying brain degeneration in Alzheimer’s disease which may explain why so many drug trials have failed. The study also identifies a clinically approved drug which breaks the vicious cycle and protects against memory-loss in animal models of Alzheimer’s. Overproduction of the protein beta-amyloid is

Adults both with and without Alzheimer’s disease have better cognition skills in the late summer and early fall than in the winter and spring, according to a new study published this week in PLOS Medicine by Andrew Lim of Sunnybrook Health Sciences Centre and the University of Toronto, Canada, and colleagues. There have been few

Testing how well people remember past events in their lives could help medical professionals make early predictions about who is at risk for developing Alzheimer’s disease, according to a new study from the University of Arizona. Researchers administered an “autobiographical memory” test to a group of 35 healthy adults, about half of whom carry the

Black people face a greater risk of dementia compared to other ethnic groups and those from Asian backgrounds are the least likely to be diagnosed, finds study of 2.5 million Scientists remain baffled as to what may be the behind the different risks But they believe both genes and environment play a role in dementia

Rates of dementia diagnosis are higher among black ethnic groups compared to white and Asian groups in the UK, a new UCL-led study has found. The study, published in Clinical Epidemiology, is the first to compare incidence of dementia diagnosis by ethnicity in any nationally representative sample. Researchers from UCL Psychiatry and the UCL Institute
