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.
Keep in mind that surgery for varicose veins done only for cosmetic reasons (that is, not medically necessary) is usually not covered by insurance. In some cases, a combination of surgery and sclerotherapy may be used to treat varicose veins. Sclerotherapy is a nonsurgical procedure in which a chemical is injected into the vein, causing the vein to close off.
