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: 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.

Visual impairment among older adults associated with poor cognitive function

Tue, 22 Aug 2017 00:00:00 PDT

In a nationally representative sample of older U.S. adults, visual impairment was associated with worse cognitive function, according to a study published by JAMA Ophthalmology.

Alzheimer's could be diagnosed early with sniff tests

Thu, 17 Aug 2017 08:00:00 PDT

A damaged sense of smell correlates with other biomarkers of Alzheimer's disease, providing hope that smell tests might help diagnose the disease earlier.

New Machine Learning program shows promise for early Alzheimer's diagnosis

Wed, 16 Aug 2017 06:00:00 PDT

A new machine learning program developed by researchers at Case Western Reserve University appears to outperform other methods for diagnosing Alzheimer's disease before symptoms begin to interfere...

Alzheimer's: Low serotonin levels may drive development

Tue, 15 Aug 2017 09:00:00 PDT

A new study examines serotonin transporters and suggests that rather than being an effect of Alzheimer's disease, low serotonin may cause the illness.

Early life physical activity may prevent cognitive decline

Tue, 15 Aug 2017 00:00:00 PDT

A new study in rodents shows how physical exercise in early life creates a cognitive reserve that improves cognition and neuronal activity in later years.

Reaction time variation may be a marker that predicts mortality in old age

Fri, 11 Aug 2017 00:00:00 PDT

A common indicator of neurobiological disturbance among the elderly may also be associated with mortality, according to a study published in the open access journal PLOS ONE by Nicole A.

Making an older brain younger by manipulating a single gene

Thu, 10 Aug 2017 07:00:00 PDT

Researchers have restored brain plasticity in the visual cortex of middle-aged mice to that of a younger state by manipulating a gene called Arc.
