Brain Research: Righting a wrong? Right side of brain can compensate for post-stroke loss of speech ♦ Formation of new blood vessels may explain intractable symptoms of Parkinson's disease

Swedish diagnostic method for Alzheimer's becomes international standard Researchers have developed a reference method for standardized measurements that diagnose Alzheimer's disease decades before symptoms appear. The method has now formally been classified as the international reference method, which means that it will be used as the standard in Alzheimer's diagnostics worldwide.
Brain's hippocampus is essential structure for all aspects of recognition memory. The hippocampus, a brain structure known to play a role in memory and spatial navigation, is essential to one’s ability to recognize previously encountered events, objects, or people – a phenomenon known as recognition memory.
Righting a wrong? Right side of brain can compensate for post-stroke loss of speech After a debate that has lasted more than 130 years, researchers have found that loss of speech from a stroke in the left hemisphere of the brain can be recovered on the back, right side of the brain. This contradicts recent notions that the right hemisphere interferes with recovery.
Formation of new blood vessels may explain intractable symptoms of Parkinson's disease Unwanted formation of blood vessels (angiogenesis) in the brain is likely to be the cause of intractable walking and balance difficulties for people who suffer from Parkinson's disease.
