Ex. 16. Write the summary of the text "Degenerative Disorders" overview

Seizure is a sudden attack often including convulsions. The seizure ends with a few minutes of deep, relaxed sleep. The causes for seizures can include scar tissue from brain disease or injury; brain infection, tumor, abscess, or hemorrhage; metabolic disturbances from kidney or liver disease. Medication greatly reduces seizures for more than 75 percent of affected persons. Regular and adequate rest is important. There are many degenerative disorders, some of them are Alzheimer's Disease, Parkinson's disease, and Multiple sclerosis. Alzheimer's disease is due to a degeneration of brain cells. Among the possible causes are genetic factors, toxic exposures, abnormal protein production, viruses, and neurochemical abnormalities. The symptoms of Alzheimer's disease are gradual loss of memory, inability to learn new information, increasing irritability, and depression. No effective treatment exists. Some medications modify the symptoms of the disease. Parkinson's disease is progressive degeneration of nerve cells in the part of the brain that controls muscle movements. The signs and symptoms of Parkinson's disease are shaking at rest, rigidity of limbs, slow, monotone voice, and difficulty in maintaining balance. The cause of this disease remains unknown. The main goal of treatment is to reverse the problems with walking, movement, and tremors.
