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.
A blood clot is a dangerous health situation with the potential to trigger heart attacks, strokes and other medical emergencies. To treat a blood clot, doctors need to find its … Continue Reading New contrast allows whole-body blood clot scans in animal model.
Currently there is no effective treatments for Alzheimer’s disease, so the focus is on prevention. In the future, medical teams may be able to provide patients with useful and actionable … Continue Reading Cardiovascular risk factors linked to Alzheimer’s disease in human study.
Examining post-mortem tissue from the brains of people with Alzheimer’s disease, Stanford University researchers state they have identified what appear to be iron-containing microglia, specialized scavenger cells that sometimes become … Continue Reading A human study identifies region specific iron-containing microglia in Alzheimer’s brains.
Some common themes are beginning to emerge from research on structural and functional brain connectivity in autism spectrum disorders (ASD). However, much more work will be needed to learn how … Continue Reading Multiple neuroimaging studies point to brain connectivity changes in autism.
For 140 years, scientists’ understanding of language comprehension in the brain came from individuals with stroke. Based on language impairments caused by stroke, scientists believed a single area of the … Continue Reading Researchers map new area of language in the human brain.
New, ultra-high-field magnetic resonance images (MRI) of the brain by researchers at the University of Illinois provide the most detailed images to date to show that while the brain shrinks … Continue Reading First evidence provided that in normal aging cell density is preserved throughout the human brain.
A new MRI study from the University of Pittsburgh has found distinct injury patterns in the brains of people with concussion-related depression and anxiety. The team state that the data … Continue Reading Neuroimaging begins to map post-concussion depression and anxiety in human study.
Women who experience more hot flashes, particularly while sleeping, during the menopause transition are more likely to have brain changes reflecting a higher risk for cerebrovascular disease, such as stroke … Continue Reading Frequent overnight menopausal hot flashes linked with brain scan changes.
