According to a team of researchers at Cornell University and three other institutions, the loss of spoken language skills may reveal early signs of Alzheimer’s disease. Recently published in the journal of Brain and Language, the study examined changes in language that occur before initial symptoms of Alzheimer’s disease appear, during a stage called Mild Cognitive Impairment (MCI). Researchers asked adults with MCI to repeat complex sentences and they compared these results to previous research on language development of complex sentences in children under 5.
A new study, led by Imperial College London, is recruiting 200 individuals living with early-stage Alzheimer’s disease for a trial drug test that may help to reverse the progression of the disease. The drug, called Liraglutide, is already used in the treatment of diabetes. Liraglutide increases the production of insulin, which has been found to help protect the brain and repair damaged neurons.
A new study, published in the Journal of Neuroscience, examined the role that an individual’s immune system may play in protecting the brain from dementia. Researchers at Duke University examined lab mice and found that immune cells called microglia release an enzyme called arginase, which lowers the level of an amino acid called arginine. Arginine is important in maintaining nerve cell health, particularly in areas of the brain that are associated with memory. The study suggests that the microglia cells act as a pathway that might be involved in the development of Alzheimer’s disease.
