Researchers at the University of Illinois at Chicago have shown for the first time that damage to a particular area of the brain and a consequent reduction in noradrenaline are associated with multiple sclerosis.

A neurologist has used an advanced form of brain imaging to identify changes in small regions of the brains of living Parkinson’s disease patients for the first time. These scientists analyzed positron emission tomography (PET) scans of the brains of 41 Parkinson’s patients and 16 normal individuals obtained at the Hammersmith Hospital, part of the Imperial College of Medicine in London, England. The scans focused on two small areas found deep in the brain called the locus coeruleus and raphe, areas that control attention and wakefulness. The analysis found positive evidence of degeneration of nerve cells in these areas.
