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.
Neurologists are doctors who specialize in conditions of the nervous system, including the brain. Neurologistsmay sub-specialize in various areas, so it is important to consult with a neurologist who has experience diagnosing and treating Alzheimerâs disease.
