The cause of Alzheimer's disease is poorly understood. About 70% of the risk is believed to be genetic with many genes usually involved. Other risk factors include a history of head injuries, depression, or hypertension. The disease process is associated with plaques and tangles in the brain.
Many types of doctors provide treatments for varicose veins and spider veins. This includes dermatologists, vascular surgeons and others. In many cases, these doctors use the same vein procedures. Your primary care doctor may refer to a specific type of vein specialist.

Dr. Favaloro, however, discovered that the veins could be used to connect the unblocked sections of a coronary artery, effectively bypassing the obstruction.
