NINDS: Stands for the National Institute of Neurological Disorders and Stroke, one of the National Institutes of Health in the U.S., whose mission is to "support and conduct research and research training on the normal structure and function of the nervous system and on the causes, prevention, diagnosis, and treatment of more than 600 nervous system disorders including stroke, epilepsy, multiple sclerosis, Parkinson's disease, head and spinal cord injury, Alzheimer's disease, and brain tumors."
Palsy: Paralysis, generally partial, whereby a local body area is incapable of voluntary movement (motor function).

Progressive supranuclear palsy: A neurologic disorder of unknown origin that gradually destroys cells in many areas of the brain, leading to serious and permanent problems with the control of gait and balance . The most obvious sign of the disease is an inability to aim the eyes properly, which occurs because of damage in the area of the brain that coordinates eye movements. Some patients describe this effect as a blurring. Another common visual problem is an inability to maintain eye contact during a conversation. This can give the mistaken impression that the patient is hostile or uninterested. Patients also often show alterations of mood and behavior, including depression and apathy as well as progressive mild dementia .
