Nervous System

• Multiple Sclerosis - the myelin sheaths around the fibers are gradually destroyed, converted to hardened sheaths
• Multiple Sclerosis - an autoimmune disease in which a protein component of the sheath is at tacked, resulting in visual and speech disturbances, lose the ability to control his or her muscles, and become increasingly disabled
• Ataxia - If the cerebellum is damaged (for example, by a blow to the head, a tumor, or a stroke), movements become clumsy and disorganized
• Meningitis - an inflammation on meninges
• Hydrocephalus - "water on the brain"
• Concussion - occurs when brain injury is slight
• Concussion - The victim may be dizzy, “see stars,” or lose consciousness briefly, but typically little permanent brain damage occurs
• Contusion - the result of marked tissue destruction
• Intracranial Hemorrhage - bleeding from ruptured vessels
• Cerebral Edema - swelling of the brain due to inflammatory response to injury
• Strokes or Cerebrovascular Accidents - occur when blood circulation to a brain area is blocked, as by a blood clot or a ruptured blood vessel, and vital brain tissue dies
• Hemiplegia - a one-sided paralysis
• Aphasias - a common result of damage to the left cerebral hemisphere , where the language production areas are located
• Hydrocephalus - if CSF begins to accumulate and exert pressure on the brain
• Alzheimer's Disease - a progressive degenerative disease of the brain that ultimately results in dementia, memory loss, a short attention span and disorientation, and eventual language loss
• Parkinson's Disease - a degeneration of specific neurons, resulting to a persistent tremor at rest, a forward-bent walking posture, shuffling gait, and a stiff facial expression
• Huntington's Disease - its symptoms are wild, jerky, and almost continuous flapping movement called chorea
• Transient Ischemic Attack - temporary brain ischemia, or restricted blood flow
• Flaccid Paralysis - nerve impulses do not reach the muscles affected, which lead to the muscles beginning to atrophy
• Spastic Paralysis - a loss of feeling or sensory input occurs in the body areas below the point of cord destruction
• Pinkeye or conjunctivitis - the inflammation of the conjunctiva, results in reddened, irritated eyes
