A new study has found that variability in night-to-night sleep time and reduced sleep quality adversely affect the ability of older adults to recall information about past events. The study also found unexpected racial differences in the type of sleep patterns tied to lower memory performance across both younger and older African American research participants.

A recent survey from the GW School of Medicine and Health Sciences found patients with psoriasis frequently use complementary or alternative therapies to treat their symptoms when traditional treatments fail.
New research may explain why an antioxidant that protects the brain is also associated with deterioration in areas susceptible to Alzheimer’s disease. The antioxidant, superoxide dismutase or SOD1, improves cognition, but a research team found SOD1’s protective benefits dramatically weaken when levels of tau proteins — a hallmark of Alzheimer’s disease — increase.
Apolipoproten E (apoeE) is a major genetic risk factor for the development of Alzheimer’s disease, yet it tends to be understudied as a potential druggable target for the mind-robbing neurodegenerative disease. Now a research team reports that a novel apoE antagonist blocks apoE interaction with N-terminal amyloid precursor protein (APP) and reduces hallmark Alzheimer’s-associated pathologies.
A new preclinical study finds that anxiety-like behavior increases when early life adversity combines with high levels of FKBP5 — a protein capable of modifying hormonal stress response. Moreover, the researchers demonstrate this genetic-early life stress interaction amplifies anxiety by selectively altering signaling of the enzyme AKT in the dorsal hippocampus, a portion of the brain primarily responsible for cognitive functions like learning and memory.
There were more than 16.9 million Americans with a history of cancer on Jan. 1, 2019, a number that is projected to reach more than 22.1 million by 2030 based on the growth and aging of the population alone.
Researchers have developed a two-step combination therapy to destroy cancer cells. They show the superior therapeutic effectiveness of the ‘one-two punch’ on cells of ovarian cancer patients, based on manipulation of the state of cellular aging.
Adults who had parents who struggled with addiction, intimate partner violence and mental illness are more than 30 times more likely to have been victims of childhood physical abuse, new study finds.
