Could our blood reveal our future dementia risk?

Thu, 08 Mar 2018 07:00:00 PDT

A new study has proposed that blood levels of branched-chain amino acids and other metabolites may reveal risk of future dementia and Alzheimer's disease.

Boosting the brain's immune cells may stop Alzheimer's

Wed, 07 Mar 2018 09:00:00 PDT

Two new studies show how a receptor activates immune cells in the brain to 'eat up' amyloid beta, thereby slowing down the progression of Alzheimer's.

Genetic score can identify Alzheimer's risk much earlier

Wed, 07 Mar 2018 07:00:00 PDT

Among adults in their 50s, researchers identified those with mild cognitive impairment — a precursor of Alzheimer's — from their polygenic risk scores.

Head injuries may lead to early Alzheimer's

Tue, 06 Mar 2018 00:00:00 PDT

Amid rising worries that sports-related head injuries may damage health long-term, a new study suggests that they may be tied to the onset of dementia.

High cholesterol in late life may mean better brain health

Mon, 05 Mar 2018 07:00:00 PDT

Having cholesterol higher than it was in midlife was linked to lower risk of marked cognitive decline in those aged 85–94, compared with those aged 75–84.

Poor hearing could lead to poor memory

Tue, 27 Feb 2018 00:00:00 PDT

New research — by scientists in Italy — suggests that a form of age-related hearing loss significantly raises the risk of mild cognitive impairment among seniors.

Alcohol use disorder is a 'major risk factor' for dementia

Wed, 21 Feb 2018 00:00:00 PDT

In a large-scale study, links between alcohol use disorder and dementia are fleshed out. The relationship is stronger than previously thought.

How does exercise preserve the aging brain?

Fri, 16 Feb 2018 07:00:00 PDT

Higher cardiorespiratory fitness is tied to stronger white matter and better cognitive performance in a study of seniors with mild cognitive impairment.

Blocking enzyme 'dramatically reverses' Alzheimer's in mice

Wed, 14 Feb 2018 08:00:00 PDT

For the first time, scientists achieve a 'dramatic reversal' of Alzheimer's-related brain damage in mice, offering hope for humans.

Vitamin B-3 could be used to treat Alzheimer's

Fri, 09 Feb 2018 09:00:00 PDT

New research finds that nicotinamide riboside, which is a form of vitamin B-3, has the potential to treat Alzheimer's. Results in mice are hopeful.

How fighting ageism may lower dementia risk

Thu, 08 Feb 2018 00:00:00 PDT

A new study examines the effect of positive and negative attitudes toward aging on the risk of developing dementia among at-risk individuals.

How bilingualism may protect against Alzheimer's

Wed, 07 Feb 2018 09:00:00 PDT

A new study examines the brain structure and memory function of monolingual and multilingual people with Alzheimer's disease and mild cognitive impairment.

Alzheimer's-related brain changes could start at 40

Mon, 05 Feb 2018 09:00:00 PDT

Researchers have uncovered a mechanism by which damage to cells that protect blood vessels may lead to Alzheimer's, and such damage could begin in our 40s.

Mon, 05 Feb 2018 03:00:00 PDT

Researchers suggest that low levels of alcohol can help to improve the function of the glymphatic system, which is the brain's waste-clearing process.

Wed, 31 Jan 2018 08:00:00 PDT

Is deep brain stimulation a way forward in treating Alzheimer's disease? A phase I clinical trial suggests that it can improve cognitive functioning.

Tue, 30 Jan 2018 08:00:00 PDT

People whose brain scans reveal very early preclinical signs of Alzheimer's disease also have disruptions in their sleep/wake cycles, a new study shows.

Aerobic exercise may be key for Alzheimer's prevention

Tue, 30 Jan 2018 00:00:00 PDT
