The question of how a change in heart health affects cerebral … Continue Reading Large-scale human study identifies link between early-stage heart and brain disease.
The brain controls most of a person’s behaviour and changes in how brain areas work and communicate with each other can alter this behaviour and lead to impairments associated with … Continue Reading New neuroimaging technique shows how the ‘social brain’ is impaired in autism.
Differences in the size and structure of certain brain areas have been found in some adults diagnosed with schizophrenia. Early findings came from the discovery of enlarged ventricles in people … Continue Reading Neuroimaging matches specific schizophrenia behaviour to the brain’s anatomy.
Many diseases involve structural changes in tissues, which are reflected in a change in their mechanical properties, such as elasticity. Using the sensitivity of their hands, and their detailed knowledge … Continue Reading Researchers have developed non-invasive palpation for the brain.
More than five million Americans are living with Alzheimer’s disease (AD). Of them, 400,000 also have Down syndrome. People with Down syndrome (DS) represent the world’s largest population of predetermined … Continue Reading Study validates beta amyloid as cause of dementia in both Alzheimer’s and Down syndrome.
Many patients with high blood pressure develop coronary artery disease or heart failure, and many die as a result. However, as hypertension is a circulatory disease all parts of the … Continue Reading Researchers successfully detect early brain damage from hypertension in human study.
Antidepressants are recommended as a first-line treatment of severe depression and for the treatment of mild-to-moderate depression that persists after conservative measures such as cognitive therapy. Experts recommend against their … Continue Reading Study maps structural brain changes caused by antidepressants.
Autism is a lifelong neurodevelopmental disorder that affects how a person communicates with, and relates to, other people. Repetitive and restricted behaviour is perhaps the most widely recognized of the … Continue Reading Neuroimaging maps behaviour, brain structure difference in girls and boys with autism.
