A neuroimaging study has revealed differences in brain activity between cannabis users and nonusers during cognitive tasks that involve switching behavior based on changing task requirements. Cannabis users exhibited weaker neural responses during these switches compared to nonusers, although both groups performed equally well on the tasks. This research was published in the Journal of Psychopharmacology.

A loss of controlled inhibition of overly excited brain cells might explain how a common knock-out anesthesia drug works. A new animal study led by researchers from the Massachusetts Institute of Technology (MIT) has found that propofol, a sedative used to safely lull people into unconsciousness for medical procedures, disrupts the brain's normal ability to regain control of highly excitable neurons.

A newly discovered communication pathway linking far-flung nerve centers within the brain and skull, and the body beyond, could provide a new target to stop migraine pain in its tracks. Researchers have long tried to pinpoint where migraines begin in the brain, and how these one-sided, nauseating headaches induce pain...

A New Pathway Found in The Brain Could Help Spell The End of Migraines

Infections and neurodegenerative diseases cause inflammation in the brain. But for unknown reasons, patients with brain inflammation often develop muscle problems that seem to be independent of the central nervous system. Now, researchers at Washington University School of Medicine in St. Louis have revealed how brain inflammation releases a specific protein that travels from the brain to the muscles and causes a loss of muscle function.

The ovaries are involved in far more than just reproduction. The two oval-shaped glands that float on either side of the uterus don't just produce and release eggs, they also pump out hormones that help keep a person's heart, bones, brain, and immune system healthy as they age. A new...

Jennifer Lopez was attacked by the style police as recent photos of her in The Hamptons made headlines this week. On July 8, the singer and actress was photographed in upstate NY while stunning in a flowing floral maxi dress, choosing a summery look with a cinched waist that more than highlighted her figure.

Research indicates that getting too little or too much sleep in later life is associated with a higher risk of developing Alzheimer's disease. The earliest affected brain regions in Alzheimer's are those involved in regulating sleep and circadian rhythms. This means that individuals in the early stages of the condition might experience sleep disturbances before showing the typical signs of memory loss or other symptoms.

Rogue antibodies may be to blame for some of long COVID’s pernicious symptoms. Two new studies suggest that antibodies that attack people’s own tissues might cause ongoing neurological issues that afflict millions of people with the disease. When scientists transferred these antibodies from people with long COVID into...

Visual hallucinations are a significant issue for many patients with Parkinson’s disease. A recent study published in the journal Brain reveals that these hallucinations are associated with a marked deficiency of cholinergic activity in specific regions of the brain, particularly the left ventral visual stream and the left superior temporal lobe. This research highlights the importance of cholinergic denervation in visual hallucinations, offering new insights into the underlying mechanisms and potential treatment options.

Vitamin B12 deficiency is common. It can lead to various health issues, affecting everything from energy levels to brain function. Vitamin B12, or cobalamin, is an essential nutrient in meat, fish, and dairy products. It is crucial for red blood cell production and a healthy nervous system. When B12 levels...

In a July 2023 Gallup survey, 62% of US adults reported drinking alcohol, while just under 20% of that group reported sometimes drinking more than they should. The link between alcohol consumption and brain health is a growing concern, especially considering projections that dementia rates could triple by 2050. Is alcohol part of the growing dementia problem—and if so, is the damage to your brain too far gone to try to correct?

Lewy body dementia stages include the first stage, middle stage, and end stage. The disease progresses as protein clumps called Lewy bodies build up in the brain and cause cognitive impairment. The buildup of Lewy bodies causes some people to have hallucinations in the early stages of the condition. As...

Blocking the activity of a protein called activin A was shown to prevent the development of levodopa-induced dyskinesia in a mouse model of Parkinson’s disease in a recent study. “By prohibiting the protein from functioning, we were able to halt the development of dyskinesia symptoms in the mouse models,”...
