Research investigating the effects of transcranial direct current stimulation (tDCS) on individuals with depression and comorbid anxiety reveals a dual impact of this noninvasive form of brain stimulation.

Memory dysfunction in Alzheimer's disease may be linked to impairment in how the brain replays our recent experiences while we are resting, according to a new study in mice by University College London (UCL) scientists.

Analysis of hospital registry data found that people who were hospitalized due to bleeding in the brain and who had taken multiple antiplatelet medications, or medications stronger than aspirin, were more likely to die before leaving the hospital compared to those not taking any antiplatelet medication, according to a preliminary study to be presented at the American Stroke Association's International Stroke Conference 2026.

Researchers led by the University of Vienna and Liège University Hospital Centre have identified genetic variants associated with a rare inherited growth disorder in two prehistoric individuals who lived more than 12,000 years ago.

An international study co-led by researchers from the University of Massachusetts Amherst and Helmholtz Munich in Germany has uncovered hundreds of genes and proteins likely to play a causal role in Type 2 diabetes, many of which would have been missed by studies relying on blood samples alone.

A type of therapy that stimulates specific brain pathways with electromagnetic pulses combined with physical therapy significantly reduced overall disability in stroke survivors compared to survivors who received sham (inactive) electromagnetic stimulation combined with physical therapy, according to a preliminary study to be presented at the American Stroke Association's International Stroke Conference 2026.

Cerebral amyloid angiopathy (CAA) is a condition where protein (called amyloid) builds up in the brain, making blood vessels weak.

Stroke survivors who were uncomfortable sharing their thoughts and feelings about their condition and future had slower physical and cognitive recovery after their stroke, according to a preliminary study to be presented at the American Stroke Association's International Stroke Conference 2026.

People who developed a type of aneurysm with a cervical artery dissection (a tear in the inner lining of the neck artery wall), a known cause of stroke, particularly in young adults, did not have an increased risk of stroke within the six months after diagnosis, according to a preliminary study to be presented at the American Stroke Association's International Stroke Conference 2026.
