Gender and Alzheimer’s Risk

Alzheimer’s disease is the most common form of dementia worldwide and is primarily attributed to increasing longevity, especially in Western countries. While Alzheimer’s affects both men and women, it is far more common in the latter.

			Does Type 2 Diabetes Increase the Risk of Alzheimer’s Disease? There are many risk factors for dementia, including Alzheimer’s disease. A majority of these are the same for cerebrovascular and cardiovascular pathologies, including obesity, hypertension (elevated blood pressure), hypercholesterolemia (elevated blood cholesterol), high sodium intake, and hyperglycemia (elevated blood sugar levels).

			Alzheimer's Disease and Sleep Disruption Sleep requirements change throughout life. As part of normal aging, sleep generally becomes briefer and fragmented, with older people often having multiple naps throughout the day. This may not be the pattern of sleep seen in patients with Alzheimer’s disease and other neurodegenerative conditions, however.

	Antidepressants can be used to treat Alzheimer’s disease Scientists at the University of Waterloo have discovered that antidepressant medications can be used to treat Alzheimer’s disease.

	Study reveals potential to monitor progression of Alzheimer’s disease by measuring brain antioxidant levels In a breakthrough human study, anti-oxidant, glutathione, which protects the brain from stress, has been found to be significantly depleted in Alzheimer's patients compared to normal subjects.

	Does Herpesvirus Cause Alzheimer's? Alzheimer’s disease (AD) is a neurodegenerative disease that progresses over time and autopsies show that hallmarks of the disease include pathological changes to patients’ brain structures, such as neurofibrillary tangles (NFTs) and amyloid deposition.

	Neuropsychiatric symptoms related to earliest stages of Alzheimer's brain pathology UC San Francisco researchers, in collaboration with the unique Brazilian Biobank for Aging Studies at the University of São Paulo, have shown that the earliest stages of the brain degeneration associated with Alzheimer's disease are linked to neuropsychiatric symptoms including anxiety, depression, loss of appetite, and sleep disturbances.

	Down syndrome may hold important clues to onset of Alzheimer's disease At first glance, Down syndrome and Alzheimer's disease, two severe brain abnormalities, may seem to have little in common. Down syndrome is a hereditary disease, the source of which has long been recognized--a triplication of chromosome 21.

	Scientists identify new biomarker for Alzheimer's disease of sporadic origin The objective of the research, undertaken in the laboratories of the IBPM, is to develop a model for studying Alzheimer's disease of sporadic origin, in other words, not due to a hereditary genetic mutation.

	Could we prevent Alzheimer's disease by treating herpes? An exciting new paper suggests that over half of all cases of Alzheimer’s disease could be traced back to herpes simplex virus 1, which causes cold sores.

	Epigenetic modifications may contribute to Alzheimer's Disease Scientists report epigenetic modifications in the brains of patients with Alzheimer's, after observing differences in histone acetylation across the genome.

	Modeling Alzheimer’s Disease Using Microfluidics An interview with Dr. Joseph Park, the incorporation of astrocytes into the Alzheimer’s-in-a-dish culture system and it's applications in drug development.

	Studies show that non-invasive imaging can detect Alzheimer's disease Results from two studies show that a new, non-invasive imaging device can see signs of Alzheimer's disease in a matter of seconds. The researchers show that the small blood vessels in the retina at the back of the eye are altered in patients with Alzheimer's.

	Exercise could reduce risk of falling for older adults with AD Alzheimer's disease is a brain disease that causes changes that kill brain cells. AD is a type of dementia, which causes memory loss and problems with thinking and making decisions.
