Different Nervous System Disorders
Nervous system disorders are many and diverse. Rush University Medical Center reports conditions of the nervous system may affect any or all parts of the nervous system, including the brain, spinal cord and any of the five senses. These highly complicated disorders commonly require coordinated services from physicians and clinicians with a wide variety of expertise.
Alzheimer's disease is marked by a progressive deterioration in brain function. This nervous system disorder occurs most often in the elderly. Symptoms include memory loss, impaired communication skills, delusions and more. The cause of Alzheimer's disease remains a mystery, but the University of Maryland Medical Center reveals ongoing research focuses on heredity, protein in the brain and environmental factors.
Multiple sclerosis affects many parts of the central nervous system, including the brain, eyes and spinal cord. Symptoms like blindness, loss of muscle control and loss of sensation may occur suddenly and then vanish. The National Multiple Sclerosis Society explains the course of the disease is unpredictable, but the cause is believed to be an autoimmune dysfunction.
Epilepsy is a nervous system disorder originating in the brain. It is marked by sudden bursts of abnormal electrical brain activity resulting in seizures. Symptoms may include convulsions, passing out or stupors, depending on the type of seizures one experiences. The Epilepsy Foundation reports the cause of epilepsy is difficult to determine unless onset of the disorder occurs in early childhood or advanced age.
Muscular dystrophy affects the nervous system by destroying the muscles responsible for motor coordination. Symptoms of muscular dystrophy include seizures, weakness and chronic lung infections. The National Institute of Neurological Disorders and Stroke describes it as a genetic disorder that may present itself in childhood or adulthood.
Bell's palsy is a nervous system disorder that is commonly mistaken for stroke by sufferers of the condition. It is characterized by immobilization of muscles on one side of the face, but unlike stroke, Bell's palsy affects only facial muscles. Other symptoms include ear pain, drooping on one side of the face and headache. The condition is caused by the pinching of nerves that control facial movements. The Mayo Clinic reports people with the herpes simplex virus, diabetes, a cold or flu, and pregnant women are at highest risk of experiencing Bell's palsy.
