Deposition of iron in the periaqueductal grey matter (PAG) is a potential biomarker for chronic migraine (CM), say researchers. Domínguez and co-workers used 3T MRI to analyse the deposition of iron in the red nucleus, globus pallidus and PAG of 55 patients with CM, 57 patients with episodic migraine (EM) and 25 controls. Patients with CM had...
Learning while asleep is a dream of mankind, but is often deemed impossible because sleep lacks the conscious awareness and neurochemical milieu thought to be necessary for learning. Current evidence for sleep learning in humans is inconclusive. To explore conditions under which verbal learning might occur, we hypothesized that peaks of slow waves...
Previously unseen oligodendrocyte dynamics and heterogeneity could limit remyelination in multiple sclerosis (MS), according to two new studies published in Nature. The findings could provide new therapeutic opportunities. Repair of myelin in demyelinating disease is thought to involve the generation of new oligodendrocytes. However, this view is...
A blood test for a protein could identify people in the early stages of Alzheimer's disease a decade or more before symptoms, such as a decline in memory and thinking, emerge.
Being overweight can lead to several health problems.
A new study of fish oils and ischemic stroke that included data on adipose tissue levels of the key fatty acids has suggested a greater benefit with eicosapentaenoic acid (EPA) than with docosahexaenoic acid (DHA) or total fish oil intake.
A recent study suggests that a warning sign may come before any symptoms of Alzheimer's disease: Adults who do not get enough deep sleep may be on their way to developing the disease.
A preliminary study (v) shows that exercise can independently and synergistically improve cognitive performance in older adults with cognitive impairment but no dementia.
The way in which our brains retrieve memories is still quite poorly understood, and we often remember moments and events in a general fashion, without recalling exact details. Why is that? New research (Nature Communications volume 10, Article number: 179 (2019)) pins down the steps of simple memory recall.
Quercetin is a flavonol, which is a sub-category of flavonoids.
