The sapphire, together with the ruby, are members of the corundum group, which is the mineralogical name for aluminium oxide that crystallised into gemstones a long time ago as a result of pressure and heat at a great depth.
Vascular Neurology Doctors and Physicians (Vascular Neurologists) Vascular neurology is the study and treatment of vascular diseases of the nervous system. A neurologist is a physician who diagnoses and treats nervous system disorders. A vascular neurologist treats patients who have disorders of the veins and arteries in the nervous system. Diseased vessels that provide circulation to the nervous system can generate problems such as a stroke or hemorrhage that affects the brain or spinal cord.
A neurologist is a doctor who is highly trained in recognizing the early symptoms of nervous dysfunction, establishing its cause, the exact location of the problem and its potential treatment. Neurologists are usually people who possess a detail-oriented way of reasoning and are very skilled at identifying the minor signs of neurological disorders. Unlike neurosurgeons, neurologists do not perform surgeries, but attempt to treat neurologic disease through medication, rehabilitation and physical therapy.
