Correct Option is A new drug, meant to potentially treat Alzheimer’s disease

China announced that GV-971 or “Oligomannate”, a new drug, meant to potentially treat Alzheimer’s disease, will be available to Chinese patients by the end of this year. GV-971 or “Oligomannate” is a seaweed-based drug, administered orally. Chinese researchers have claimed it is capable of treating mild to moderate Alzheimer's and may improve cognition. It has been jointly developed by the Shanghai Institute of Materia Medica and the Ocean University of China and Green Valley Pharmaceutical Company Ltd. Hence, option (a) is the correct answer. Value Addition: Alzheimer’s disease is a progressive brain disorder that typically affects people older than 65. When it affects younger individuals, it is considered early onset. Alzheimer’s involves two proteins, called beta amyloids and tau. When levels of either protein reach abnormal levels in the brain, it leads to the formation of plaque, which gets deposited between neurons, damaging and disrupting nerve cells. Alzheimer’s disease is also the most common cause of dementia — which is a syndrome and not a disease in itself, and whose symptoms include loss of memory, thinking skills, problems with language, changes in mood and deterioration in behaviour.
