Sleep deprivation increases brain protein linked to Alzheimer's disease

Losing just one night of sleep led to an immediate increase in beta-amyloid, a protein in the brain associated with Alzheimer's disease, according to a small, new study by researchers at the National Institutes of Health. In Alzheimer's disease, beta-amyloid proteins clump together to form amyloid plaques, a hallmark of the disease.

			Study reveals increased risks for Alzheimer's and suicide among youth in polluted cities A University of Montana researcher and her collaborators have published a new study that reveals increased risks for Alzheimer's and suicide among children and young adults living in polluted megacities.

			Study shows presence of beta-amyloid dimers in the brains of Alzheimer's patients The most widely used biomarkers for the early detection of Alzheimer's disease (AD) are currently the concentrations of beta-amyloid and phosphorylated Tau in cerebrospinal fluid. However, it has been observed that not all individuals with alterations in these biomarkers develop the disease.

	Traumatic brain injury associated with higher risk of dementia The risk of dementia, including Alzheimer's, was significantly higher in people who had experienced a traumatic brain injury (TBI) than with people who had no history of TBI, according to one of the largest studies to date on that association.

	People with rare dementia may employ intact brain areas for help with language People with a rare dementia that initially attacks the language center of the brain recruit other areas of the brain to decipher sentences, according to new research led by a University of Arizona cognitive scientist.

	Protein linked with Alzheimer's disease affects different brain cells differently Amyloid beta, a protein linked with Alzheimer's disease, has different properties in different cell types in the brains of fruit flies.

	The memory area of the brain may also yield vital clues about mental health illnesses The hippocampus is an area of the brain commonly linked with memory and dementia. But new U of T Scarborough research finds that it may also yield important clues about a range of mental health illnesses including addiction, anxiety and depression.
