Document Summary
Multiple sclerosis, characterized by multiple areas of demyelination the nervous system, less effective communication of the neurons, symptoms of ms depend on location of demyelination. Motor systems = difficulty in motor movements: 20-40y/o, 60 in 100,000 people, progressive and unpredictable, associated with cold climates. Above the 37th parallel: genetic component. Inherited vulnerability to an environmental agent rather than the disease being inherited: cognitive deficits. Attention, memory, language, motor speed and dexterity. Memory deficits related to retrieval rather than recognition: show frontal lobe atrophy. Disconnection between frontal lobe and subcortical structures such as the thalamus: amyotropic lateral sclerosis (als, lou gehrig"s disease, degeneration of upper and lower motor neurons which control movement of muscles, progressive and terminal diseas. Followed by involvement of the muscles of the trunk and face. Eventually muscles of breathing are affected and require mechanical ventilation: causes. Linguistic ability was thought to be motor, but temporal lobe atrophy has been seen and can affect nonmotoric linguistic impairments.
