Alzheimer's / Dementia News From Medical News Today

The word dementia describes a set of symptoms that may include memory loss and difficulties with thinking, problem-solving or language. Dementia is caused when diseases, such as Alzheimer’s disease or a series of strokes, damage the brain. Dementia is p

Alzheimer's: Word processing duration may predict onset

Fri, 20 Oct 2017 00:00:00 PDT

Delayed word processing may predict the onset of Alzheimer's disease, scientists find. The research may lead to new testing practices.

How a green tea compound could prevent Alzheimer's

Fri, 13 Oct 2017 10:00:00 PDT

Researchers reveal how a compound in green tea called EGCG prevents the formation of toxic beta-amyloid plaques, which are a hallmark of Alzheimer's.

Menopause may trigger Alzheimer's disease

Wed, 11 Oct 2017 08:00:00 PDT

A new study looked at the metabolic changes in the brains of menopausal and perimenopausal women and found potential triggers for Alzheimer's disease.

Dementia: Study helps to unravel the cause of brain cell death

Mon, 09 Oct 2017 07:00:00 PDT

Researchers suggest that the loss of a gene called LSD1 plays a role in the brain cell death that occurs with Alzheimer's and frontotemporal dementia.

Women's dementia risk increased by midlife hypertension

Thu, 05 Oct 2017 00:00:00 PDT

Women who develop high blood pressure in their 40s may be at greater risk of dementia, a new study finds, but this association may not ring true for men.

Bilingualism: What happens in the brain?

Wed, 04 Oct 2017 08:00:00 PDT

With the number of bilingual individuals increasing steadily, find out how bilingualism affects the brain and cognitive function.

Sniffing out dementia with a simple smell test

Fri, 29 Sep 2017 07:00:00 PDT

A study finds that older adults who could not identify at least 4 out of 5 odors in a smell test were twice as likely to develop dementia 5 years later.

Alzheimer's disease: When does personality start to change?

Fri, 22 Sep 2017 09:00:00 PDT

A new study examines whether the personality of those affected by dementia or mild cognitive impairment starts to change before the onset of the disease.

Too much or too little magnesium can raise dementia risk

Thu, 21 Sep 2017 09:00:00 PDT

A recently published study investigates the link between both high and low magnesium serum levels and the risk of developing dementia.

Alzheimer's: Targeting ApoE gene may 'stop the disease'

Wed, 20 Sep 2017 10:00:00 PDT

The ApoE gene may have a more influential role than first thought; it may amplify the damage done by the tau protein, causing neurodegeneration.

Alzheimer's disease: New genetic culprit found

Mon, 18 Sep 2017 08:00:00 PDT

A new study challenges the traditional understanding of Alzheimer's disease, as scientists point to a new gene that may be responsible for the illness.

How to keep your brain healthy as you age

Fri, 08 Sep 2017 00:00:00 PDT

A new advisory from the American Heart Association outlines seven steps for preventing age-related cognitive decline and vascular dementia.

Stabilizing TREM2 - a potential strategy to combat Alzheimer's disease

Fri, 01 Sep 2017 00:00:00 PDT

Uncovering the molecular mechanism behind a rare genetic risk factor of Alzheimer's disease points to a new therapeutic target.

'Seeing' robot learns tricky technique for studying brain cells in mammals

Fri, 01 Sep 2017 00:00:00 PDT

Whole-cell patch clamp electrophysiology, or whole-cell recording (WCR), is the gold-standard technique for studying the behaviour of brain cells called neurons under different brain states such as...

Alzheimer's disease: Scientists close in on how it starts and how to stop it

Thu, 31 Aug 2017 07:00:00 PDT

A new study shows how a series of events involving immune cells, amyloid beta, and tau could be the start of Alzheimer's and names targets for stopping it.

The brain's defense cells live longer than expected

Wed, 30 Aug 2017 00:00:00 PDT

In mice, microglia may persist the entire lifespan of the animal. The cells' lifetime may be linked to their role in immune memory and neurodegenerative diseases.

Dancing may help to combat brain aging

Tue, 29 Aug 2017 09:00:00 PDT

Researchers have found that both strength-endurance training and dancing increased hippocampal volume in the brain, but the latter had the greatest impact.

What happens to the brain as we age?

Tue, 29 Aug 2017 08:00:00 PDT

The brain begins to decline with age. We examine what happens to the brain over time and whether the rate of decline can be slowed or even prevented.

Alzheimer's: Sex matters, but so does age

Tue, 29 Aug 2017 00:00:00 PDT

A new meta-analysis suggests that women and men face the same Alzheimer's genetic risk factor, but women are more susceptible between ages 65 and 75.

Algorithm could predict Alzheimer's risk years before symptoms occur

Sun, 27 Aug 2017 00:00:00 PDT

Researchers have created an algorithm that could predict the risk of Alzheimer's in patients with mild cognitive impairment 2 years before symptoms arise.

Dreaming may keep dementia at bay

Thu, 24 Aug 2017 00:00:00 PDT

A new study finds that insufficient REM sleep - the sleep phase wherein we do most of our dreaming - is strongly linked with an increased risk of dementia.

How an eye test could detect Alzheimer's

Wed, 23 Aug 2017 09:00:00 PDT

Researchers reveal how a novel imaging technique could diagnose Alzheimer's disease by detecting beta-amyloid plaques in the retinas of patients.

Could lithium help to prevent dementia?

Wed, 23 Aug 2017 08:00:00 PDT

A study of more than 800,000 people in Denmark finds that those exposed to higher levels of lithium in drinking water were at lower risk of dementia.
