Nervous system disease,any disease or condition
that affects the functioning of the human nervous system. Whatever man perceives, observes, and affects and all the undesirable disturbances of the body depends upon the functioning of the nervous system. The skeletons and muscles support and transport the body, and provide nutrients to the digestive system, heart, and lungs; but the nervous system manifests the human—the brain—and commands all reactions, thought, and action. Disruption in the functions of the nervous system causes changes in the body.

The first part of this article explains nerve examinations
—medical history, patient physical examinations, and diagnostic tests and procedures that can be used to provide information to a physician about a complaint of potential neurological disorder. The principles used to localize a disease in the nervous system are then explained. The third part of this article offers an overview of the pathological process.
An old saying in medicine, “Listen to the patient. They’re telling you the diagnosis,” is especially true in neurology. A patient’s symptom description is an invaluable resource that allows the physician to know the type and location of potential neurological disease. Taking a patient’s medical history, the neurologist notes the patient’s awareness, memory deficit, currency and trick, behavior and expression, speech, and to some extent personality level. Neurologists also note symptoms such as pain, headaches, loss of sense, weakness, irregularity, loss of certain muscle groups, and abnormal movements.Nervous system disease,And headache problemsNervous system disease,And headache problems online knowledge? medical study by online Education
Altered consciousnessThe ability to notice and react to one’s environment is
not a distant trend but continuity. The clear level of unconsciousness goes from mild coma, with strong stimulus only generating clumsy motor reactions, to deep coma, with only an emergency movement or no response. This type of depression of consciousness occurs when there is malfunctioning of functions of the cerebral cortex. Brain disorders can cause coma if swelling caused by disease caused by other parts of the brain or if he experiences local illness such as encephalitis, stroke or hesitation. Brain cortex diseases cause coma caused by opioids, blood glucose or oxygen deficiency, brain hemorrhage, and some rare dysfunctional disorders that occur within weeks or months through the level of consciousness.
Headache When pressure increases inside the cranium,
Brain swelling, infection, bleeding, tumors, stress, or obstructed flow of cerebral fluid can lead to directional headaches. Also, pain can be felt in the head region as though the pain causing disease is located elsewhere. For example facial pain is sometimes felt with anemia in the heart. problems
Stress headaches are caused by prolonged contractions
of the muscles moving from the front to back above the skull. These headaches are often caused by stress. Constant pressing or pulling pain, often with a pulsing component, is commonly described. Sciatica headaches can be combined with concurrent stress headaches and are
