Obsessive–compulsive disorder (OCD) negatively impacts the lives of millions of people worldwide, but more effective treatments could be on the way after researchers were able to identify specific neural biomarkers associated with the condition. These biomarkers are patterns of brain activity present in people with OCD when they’re acting compulsively, and which don’t show up the rest of the time. …

Eating Mediterranean-style could help guard against dementia, even for those most at genetic risk. Credit: Shutterstock A large-scale study found that following a Mediterranean-style diet significantly reduces the risk of dementia, particularly in people genetically predisposed to Alzheimer’s. Mediterranean Diet Linked to Dementia Risk Reduction A new study led by investigators from Mass General Brigham, Harvard T.H. Chan School of …

The brain controls the release of glucose in a wide range of stressful circumstances, including fasting and low blood sugar levels. However, less attention has been paid to its role in day-to-day situations. In a study published in Molecular Metabolism, University of Michigan researchers have shown that a specific population of neurons in the hypothalamus help the brain maintain blood …

Suffering a head injury could raise the risk of developing a brain tumour later in life, concerning research today suggested.  Age, being overweight or obese and exposure to certain types of radiation through x-rays and CT scans, have long been known risk factors of brain tumours. But, US researchers found adults were ‘significantly’ more likely to develop a malignant brain tumor, a …

Surgeons have transplanted a lung from a genetically modified pig into a brain dead human recipient for the first time and found it functioned for nine days, researchers have revealed. The work is the latest development in a technique called xenotransplantation that is aimed at solving the organ shortage crisis: according to the World Health Organization, only up to 10% …

A groundbreaking study by UCSF researchers has pinpointed the protein FTL1 as a key contributor to age-related cognitive decline, particularly affecting the hippocampus. Elevated FTL1 levels in older mice correlated with diminished brain cell connections and impaired cognitive function. Remarkably, reducing FTL1 in aged mice reversed these effects, boosting memory and neural connections. Aging is often accompanied by a decline …

The Healthy Brain Aging Initiative was developed by Tulane’s Neurology Chair, Dr. Demetrius Maraganore, in response to the notably high incidence of Alzheimer’s disease and dementia in Louisiana. The research from this program is focused on Alzheimer’s and dementia prevention and memory disorder treatments using the latest evidence-based research and movement disorders treatment, like Parkinson’s, related to brain aging. Maraganore, …

Immune cells in the human brain may be critical to orchestrating the organ’s development in the womb because they trigger a dramatic increase in an important type of nerve cell, new research suggests. Estimates suggest that these key cells, known as inhibitory interneurons, make up some 25% to 50% of the neurons in the adult cortex, the wrinkled tissue that …

Alexa Ray Joel shared an update on her father Billy Joel’s health as the legendary singer battles a brain disorder. Billy, 76, announced that he had been diagnosed with normal pressure hydrocephalus (NPH) – which affects his vision, hearing and balance – on social media in May. The “Riverside Way” singer, who is the daughter of Billy and his ex-wife, …

Noland Arbaugh, the first person to get a brain chip implant by Elon Musk’s Neuralink, has shared how the new technology has transformed his life 18 months after the surgery. Notably, Arbaugh had dislocated two of his vertebrae during a swimming accident in 2016 and thereafter lost sensation and movement below his shoulders. Arbaugh had received the implant in 2024, …
