Nervous System Disorders
There are many nervous system disorders. A stroke occurs when the blood flow to the brain is interrupted. The brain cells in the immediate area begin to die due to the lack of oxygen and nutrients. The two types of stroke include Ischemic: a blood clot that blocks a blood vessel leading to the brain; and Hemorrhagic: a blood vessel breaks and bleeds into the brain. The effects of a stroke can be mild to severe paralysis, difficulty speaking, difficulty thinking, aproxia, aphasia, loss of coordination, and spasticity.
Multiple Sclerosis is an autoimmune disease which mean the the body's own immune system deteriorates the myelin sheath. The myelin sheath is destroyed and replaced by scars and hardened tissue. This demyelination interrupts communication between the brain and the rest of the nervous system, which slows or blocks nerve impulses. There is no cure for this disease and the medical treatment focuses on combating the autoimmune response and management of the syndrome.
Huntington's Disease is a genetically inherited disease that causes degeneration of neurons in the basal ganglia. Over time, this degeneration causes uncontrolled movement, loss of intellectual faculties, and emotional disturbances. There is not a cure for this disease, but speech, physical, and occupational therapy help keep the muscle strong and more flexible. Medication can control some of the symptoms, but progression of this disease typically requires long-term care in a nursing facility.
Alzheimer's is an age-related, non-reversible brain disorder that is characterized by memory loss and confusion. It is the most common form of dimentia and is caused by the breakdown of connections between neurons and eventual neuron death. The loss of connection between neurons due to plaques and tangles are responsible for the memory loss. There is no cure and it is irreversible.
