The only detox you need is sleep — but it’s not totally clear why

(Kat Eschner/ Popular Science) — Rapid Eye Movement (REM) sleep gets the most hype, but it’s far from the only important part of our snooze cycle. A new study shows that slow-wave sleep (SWS), the deepest phase of non-REM sleep, may be the key to detoxing our brains. The study identified a cycle that occurred […]

Alzheimer’s directly kills brain cells that keep you awake

(Yasemin Saplakoglu/ Live Science) — Alzheimer’s disease might be attacking the brain cells responsible for keeping people awake, resulting in daytime napping, according to a new study. Excessive daytime napping might thus be considered an early symptom of Alzheimer’s disease, according to a statement from the University of California, San Francisco (UCSF). Some previous studies […]

Women’s mid-life stress linked to memory decline

(Futurity) — A new study links stressful life experiences among middle-aged women — but not men — to greater memory decline in later life. The researchers say their findings add to evidence that stress hormones play an uneven gender role in brain health, and align with well-documented higher rates of Alzheimer’s disease in women than […]

How frontotemporal dementia affects ‘moral emotions’

(Ana Sandoiu/ Medical News Today) — Researchers reveal a marker and new testing tool of frontotemporal dementia that may help distinguish this condition from Alzheimer’s disease. Frontotemporal dementia (FTD) is a less common form of dementia than Alzheimer’s. Sometimes called Pick’s disease or frontal lobe dementia, this condition occurs when brain cells in the frontal […]

Fewer periods may mean higher dementia risk

(Amy Norton/ HealthDay) — A new study suggests that the fewer menstrual periods a woman has in her lifetime, the higher her risk of dementia — though the reasons, for now, are unclear. The study was based on close to 16,000 women. It found that those who started having periods at age 16 or later […]

Blood test could detect Alzheimer’s before symptoms appear

(Tim Newman/ Medical News Today) — A group of researchers is close to developing a blood test that can detect Alzheimer’s disease long before symptoms appear. The test will be extremely useful for scientists trying to understand and treat the condition. One of the major issues that hamper Alzheimer’s research is that the disease is […]

Alzheimer’s-related brain changes could start at 40

(Honor Whiteman/ Medical News Today) —  Scientists may have advanced our understanding of the brain mechanisms behind Alzheimer’s disease, after uncovering a process that precedes the buildup of toxic proteins that is a hallmark of the condition. In a mouse study, scientists at the University of Southern California (USC) in Los Angeles reveal how damage […]

McGill researchers discover non-invasive method to detect Alzheimer’s

(McGill University news release) — New research has drawn a link between changes in the brain’s anatomy and biomarkers that are known to appear at the earliest stages of Alzheimer’s disease (AD), findings that could one day provide a sensitive but non-invasive test for AD before cognitive symptoms appear. Scientists have known for some time […]
