Alzheimer's Disease News and Research

RSS

Alzheimer's disease (AD) is an irreversible, progressive brain disease that slowly destroys memory and thinking skills and, eventually, the ability to carry out the simplest tasks of daily living. In most people with AD, symptoms first appear after age 60. AD is the most common cause of dementia among older people, but it is not a normal part of aging. Dementia refers to a decline in cognitive function that interferes with daily life and activities. AD starts in a region of the brain that affects recent memory, then gradually spreads to other parts of the brain. Although treatment can slow the progression of AD and help manage its symptoms in some people, currently there is no cure for this devastating disease.

Life expectancy and nursing home admission in people with dementia

The average life expectancy of people diagnosed with dementia ranges from 9 years at age 60 to 4.5 years at age 85 for women and from 6.5 to just over 2 years, respectively, in men, finds a systematic review of the latest evidence in The BMJ today.

Researchers uncover molecular mechanisms driving RNA processing defects in Huntington's disease

A University of California, Irvine-led research team has discovered intricate molecular mechanisms driving the RNA processing defects that lead to Huntington's disease and link HD with other neurodegenerative disorders such as amyotrophic lateral sclerosis, frontotemporal lobar dementia and Alzheimer's disease.

High blood pressure may not harm brains of 90-year-olds, study finds

A study led by the University of California, Irvine has found cardiovascular conditions such as high blood pressure and diabetes, which are known to contribute to brain blood vessel damage in younger populations, not to be associated with an increased risk of such harm in individuals 90 and older.

Breakthrough in protein homeostasis offers potential for preventing Alzheimer’s

Scientists have uncovered a powerful ally in the fight against neurodegenerative diseases: a nucleolar complex that plays a pivotal role in maintaining cellular health through protein homeostasis (proteostasis), by which cells maintain the balance and proper functioning of their proteins.

Addressing barriers to healthcare delivery for people with Alzheimer's disease and related dementias

Kosali Simon, PhD, M.A., a professor with the Paul H. O'Neill School of Public and Environmental Affairs and a Regenstrief Institute research scientist; and Katherine Baicker, PhD, University of Chicago provost, will co-lead an expected nearly $16 million National Institutes of Health's (NIH) National Institute on Aging (NIA) program to explore critical aspects of healthcare delivery for individuals living with Alzheimer's disease and related dementias (ADRD).

Microglial cells may hold key to Alzheimer's plaque removal

Immune cells in the brain called microglia can partially break down large amyloid plaques characteristic of Alzheimer's disease by latching on to them, forming a sort of external stomach and releasing digestive enzymes into the space, according to a preclinical study by Weill Cornell Medicine investigators.
