The electrical activity of the brain can be recorded by suitably placed electrodes over the scalp. Abnormal electrical activity occurs in seizure disorders, coma, poisoning, tumors etc. In such conditions, the ECG gives valuable information. For the diagnosis of brain death, the EEG evidence is absolutely essential. A flat record for 10 minutes is diagnostic.

Since haloperidol, along with other neuroleptic drugs later developed, represses dopamine reception, a common theory since that time has been that dopamine plays an important role in regard to the manifestation of TS symptoms, though the exact mechanism remains unclear.

Serious eye conditions, such as macular degeneration, glaucoma and cataracts are much more prevalent among adults and senior members of the population. According to the Alliance for Aging Research, visual impairment has been identified as one of the four most significant contributors to lost independence among senior citizens.

Neurological disease due to diabetes has four main types. Patients may have a form or a symptom of many types at once. Most of the symptoms manifest slowly as the patient did not notice until a serious injury. Some patients have symptoms even before diabetes is diagnosed.

Gluten ataxia, the most common cause of previously unexplained ataxia, is associated with gut disease in only about a third. Usually there is an absence of the specific antibodies in the blood diagnostic for celiac disease but elevated gliadin antibodies. Brain tissue examined after brain biopsies or an autopsy has been found to contain deposits of gliadin and/or tissue transglutaminase in the absence of antibodies in the blood.

Normally, the cells number below 5/cmm and all of them are lymphocytes. Rise in cells is called pleocytosis. Lymphocytic pleocytosis occurs in viral, tuberculous and syphilitic meningitis. Neutrophils pleocytosis occurs in pyogenic meninigits, e.g meningococci, pneumococci. Mixed pleocytosis (both lymphocytes and neutrphils) occurs in leptospirosis, tuberculosis or following subarachnoid hemorrhage. In neuroleukemia immature white cells may be seen in the CSF.

Some of the most common symptoms of poor blood circulation in the body are tingling, burning and cramping sensations in the peripheral organs like legs, feet, arms and hands. These symptoms are almost sure signs that blood can't flow freely through the whole body and supply major organs with vital nutrients and oxygen for various reasons.

The patient is asked to open and close his eyes, without and against resistance. Note the size of the palpebral fissure. Paralysis of the levator palpebrae superioris causes drooping of the upper eyelid (ptosis). Paralysis of upper tarsal muscles causes pseudoptosis, in which there is parital ptosis but the patient can voluntarily raise the eyelid.

Information provided by Eli Lilly accompanying prescriptions of this drug note the possibility of tachycardia, and increased blood pressure. Tourette's disorder, though the etiology is not fully known is being examined as difficulties arising in the metabolism of dopamine, serotonin, and norepinephrine.

A full medical examination is one of the first things that will be done when a patient is suspected of having a stroke. The patient's vital signs will be checked as well as detailed testing to evaluate the nerves and muscles which will consist of a testing the patients reflexes, strength, sensation, and coordination.
