Evidence of brain changes in those at risk of bipolar disorder captured with MRI scans

A study that showed changes in the brain in those at risk of developing bipolar disorder raises new hopes about early intervention.

Scientists find that the impact of social media on wellbeing varies across adolescence

Girls and boys might be more vulnerable to the negative effects of social media use at different times during their adolescence, say an international team of scientists. The researchers show that, in UK data, girls experience a negative link between so…

Study finds neurons that encode the outcomes of actions

A group of neurons in the brain’s striatum encodes information about the potential outcomes of different decisions. These cells become particularly active when a behavior leads a different outcome than what was expected, which the researchers believe h…

Scientists identify overgrowth of key brain structure in babies who later develop autism

New research demonstrates overgrowth of the amygdala in the first year of life, before babies show most of the behavioral symptoms that later consolidate into a diagnosis of autism. This overgrowth may be unique to autism, as babies with fragile X synd…

Distant regions of the human brain are wired together by surprisingly few connections

Understanding how the brain functions, particularly how information is processed during different activities, is difficult without knowing how many axons are in the brain and how many connect different functional regions. A new study shows that despite…

Researchers develop new antibody test to diagnose multiple sclerosis

Researchers have validated a new antibody test to diagnose multiple sclerosis (MS), a potentially disabling disease of the brain and spinal cord.

Limiting energy in neurons exacerbates epilepsy

Epilepsy, one of the most common neurological disorders, is characterized by the spontaneous repetition of seizures caused by the hyperactivity of a group of neurons in the brain. Could we therefore reduce neuronal hyperactivity, and treat epilepsy, by…

Exercise holds even more heart health benefits for people with stress-related conditions

Regular physical activity had nearly doubled the cardiovascular benefit in individuals with depression or anxiety, compared with individuals without these diagnoses, according to a new study.

How the gut communicates with the brain

New research has discovered how the enteric nervous system — or ‘second brain’ — can communicate with both the brain and spinal cord, which up until now had remained a major mystery. The study found specialized cells within the gut wall release serot…

One in four children who have suffered a minor head injury is liable to suffer from chronic post-concussion syndrome, study finds

A new study found that one in four children (25.3 percent) who have been discharged from the emergency room after a mild head injury are misdiagnosed and continue to suffer from persistent post-concussion syndrome for many years.
