How to safely stop antidepressants

People may wish to stop taking antidepressants for several reasons, but stopping suddenly can cause withdrawal symptoms or relapse. Here, we look at why stopping antidepressants can be hard and how to relieve withdrawal symptoms. We discuss which antid…

Sleep disorder linked with changes to brain structure typical of dementia

Obstructive sleep apnea is associated with changes to the structure of the brain that are also seen in the early stages of dementia, according to a new study.

Brain study paves way for therapy for common cause of dementia

Scientists have uncovered a potential approach to treat one of the commonest causes of dementia and stroke in older people. Studies with rats found the treatment can reverse changes in blood vessels in the brain associated with the condition, called ce…

Why males are more at risk than females for neurodevelopmental disorders

Small talk not as bad as previously thought

People who engage in more substantive conversations tend to be happier, a new study confirms. Yet researchers found, contrary to previous findings, that idle small talk is not necessarily negatively related to well-being.

Neuroscientists uncover secret to intelligence in parrots

Neuroscientists have identified the neural circuit that may underlay intelligence in birds, according to a new study. The discovery is an example of convergent evolution between the brains of birds and primates, with the potential to provide insight in…

Feeling young could mean your brain is aging more slowly

While some people are young at heart, others feel older than their age — and a recent study finds that this ‘subjective age’ may reflect brain aging. Researchers found that elderly people who feel younger than their age had a younger estimated brain a…

Consciousness is partly preserved during general anesthesia

Researchers have gained new information on brain activity during general anesthesia by recording changes in the electrical activity of the brain. They discovered that changes in electroencephalogram correlated with the loss of consciousness itself and …
