In most of the cases there is no particular treatment except for love and support of the family.The most common diseases neurological are Alzheimer's disease, dementia, brain tumor, Cushing's syndrome, epilepsy, Parkinson's disease and schizophrenia. The main symptom of the Alzheimer's disease is the memory loss. The patient faces difficulty in recalling the past events or he mix ups the past and present events. This disease is usually diagnosed in older people so the family of the patient mistakes the symptoms with age related issues. Dementia and Alzheimer's disease fall into the same category because Alzheimer is a type of dementia. It is the result of the intermingling of different nerves in the brain. Brain tumors are equivalent to brain cancer. They develop because of the abnormal division of cells. However, all brain tumors are not fatal. In fact many such cases have been successfully operated upon. The symptoms include dizziness, a searing pain in the temples which proceeds to the neck region, fatigue, irritation and tremors. Cushing's syndrome is usually termed a self-inflicted disease. Most of the neurological disorders happen due to an unfortunate stroke of luck but Cushing's syndrome is the result of too much drugs and sleeping pills. Unnecessary or self-medication also generates this syndrome. The basic symptoms are excessive and rapid weight gain, abnormal sweating and bruising on legs, arms and buttocks. Epilepsy is a disease in which man is seized by recurrent seizures and tremors. High blood pressure and anxiety are the root cause of this disorder. Unfortunately this disease is controlled through medication but not fully cured.
