Vasculitis including Temporal Arteritis - Vasculitis is an inflammation of the vascular system, which includes the veins, arteries, and capillaries. Dysfunction may occur due to the inflammation itself or over time as the blood vessel walls swell, harden, thicken, and develop scar tissue. This narrows the passage through which blood can flow. As the condition progresses, it can slow or completely stop the normal flow of blood. Vasculitis can cause problems in any organ system, including the central (CNS) and peripheral (PNS) nervous systems.

Von Economo’s Disease - or Encephalitis lethargica (EL) is a form of encephalitis. Also known as sleeping sickness (different from the sleeping sickness transmitted by the tsetse fly), EL is a devastating illness that swept the world in the 1920s and then vanished as quickly as it had appeared. EL attacks the brain, leaving some victims in a statue-like condition, speechless and motionless. Between 1917 and 1928, an epidemic of encephalitis lethargica spread throughout the world, but no recurrence of the epidemic has since been reported, though isolated cases continue to occur.

Von Hippel-Lindau Disease (VHL) - (VHL) is a rare, genetic multi-system disorder characterized by the abnormal growth of tumors in certain parts of the body (angiomatosis). The tumors of the central nervous system (CNS) are benign and are comprised of a nest of blood vessels and are called hemangioblastomas (or angiomas in the eye). Hemangioblastomas may develop in the brain, the retina of the eyes, and other areas of the nervous system. Other types of tumors develop in the adrenal glands, the kidneys, or the pancreas.

Von Recklinghausen's Disease - or Neurofibromatosis 1 (NF1) is characterized by spots of increased skin pigmentation combined with peripheral nerve tumors and a variety of others dysplastic abnormalities of the skin, nervous system, bones, endocrine organs and blood vessels. The peripheral nerve tumors of two types, schwannomas and neurofibromas. Both types of tumor occasionally become malignant.
