Research has found that the brains of people with PTSD process traumatic personal memories differently from sad ones. The findings suggest traumatic memories activate a distinct pathway, which may be critical to PTSD treatment.

Research has revealed how genetic changes in a specialized population of brain cells called microglia contribute to neuroinflammation and, in turn, to Alzheimer’s disease. The findings could lead to more effective, targeted therapeutics.

A study found that interrupting prolonged sitting with intermittent half-squats improved blood flow to the brain and, with it, cognitive functioning and concentration. This simple exercise could be done at work or home to provide a brain boost.

Multiple sclerosis (MS) is a debilitating disease with few treatment options. But in a new clinical trial, scientists have tested a promising new therapy involving injections of stem cells, which seems to slow progression of the disease.

New research is the first to reveal microstructural brain changes in long COVID patients compared to fully recovered patients and uninfected subjects. The findings indicate long COVID symptoms can be associated with changes to specific cerebral networks.

Research has found that signals linked to how food tastes are sent to our brains almost immediately to slow our eating pace, with the well-known stretch signals from the gut coming later, providing greater insights into how the body controls appetite.

Researchers have found that SARS-CoV-19 infection can cause ‘zombie’ cells to accumulate, contributing to the brain fog associated with long COVID, and have identified drugs that can reverse this virus-related premature aging.

In a significant development for brain health, scientists have found that hemorrhages can occur due to a faulty interaction between aged red blood cells and narrow capillaries. Injured or damaged blood vessels were thought to be the sole culprit.

For centuries red wine has been thought to trigger headaches more than other drinks, and it's been unclear exactly why this is the case. Now researchers think they've solved the mystery, and the culprit is a chemical previously thought to be beneficial.

Two recent studies may have discovered how electroconvulsive therapy is so effective at alleviating some mental illnesses, especially severe depression, something that has puzzled psychiatrists and neuroscientists for decades.

Analyzing the functional connectivity of different brain networks, researchers found that Alzheimer’s disease disrupts areas of the brain beyond those relating to memory and produces changes distinct from those seen in healthy aging.

A first-of-its-kind study has identified overactive inflammation and loss of critical protective mechanisms in the brain as potential contributors to suicide risk and may lead to the use of anti-inflammatory medications as a way of reducing this risk.
