Wed, 15 Feb 2017 00:00:00 PST

New research examines the metabolism of brain cells and uncovers the calcium exchange mechanism that could lead to Alzheimer's disease.



Children of patients with C9orf72 mutations are at a greater risk of frontotemporal dementia or ALS at a younger age

Wed, 15 Feb 2017 00:00:00 PST

The most common genetic cause of the brain diseases frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS) is a mutation in the C9orf72 gene.



Gut bacteria may play a role in Alzheimer's disease

Tue, 14 Feb 2017 00:00:00 PST

New research from Lund University in Sweden has shown that intestinal bacteria can accelerate the development of Alzheimer's disease.



Alzheimer's may be linked to defective brain cells spreading disease

Tue, 14 Feb 2017 00:00:00 PST

Rutgers scientists say neurodegenerative diseases like Alzheimer's and Parkinson's may be linked to defective brain cells disposing toxic proteins that make neighboring cells sick.



'Helper cells' can turn toxic in brain injury and diseases

Mon, 06 Feb 2017 07:00:00 PST

Astrocytes induced by central nervous system injury and disease normally help repair damage. Now, a study finds some can turn rogue and kill cells instead.



Link between sleep and cognitive impairment in the elderly

Thu, 02 Feb 2017 00:00:00 PST

Daytime sleepiness is very common in the elderly with prevalence rates of up to 50 percent.

Wed, 01 Feb 2017 09:00:00 PST

New research suggests that high exposure to fine particulate air pollution may increase the risk of Alzheimer's disease and other dementias.



Low levels of glucose in the brain may trigger Alzheimer's

Tue, 31 Jan 2017 09:00:00 PST

New research uses mice to show how glucose deprivation leads to neural tangles typical of Alzheimer's disease, triggering cognitive and memory impairment.



A glitch in 'gatekeeper cells' slowly suffocates the brain

Tue, 31 Jan 2017 06:00:00 PST

Abnormality with special cells that wrap around blood vessels in the brain leads to neuron deterioration, possibly affecting the development of Alzheimer's disease, a USC-led study reveals.
