Definition. Asperger syndrome is a neurological disorder resulting in a group of social and behavioral symptoms. It is part of a category of conditions called autism spectrum disorders. Children with Asperger syndrome usually have normal intelligence and do not have the language problems typical of autism.
As plaque deposits grow, a condition called atherosclerosis results. This condition causes the arteries to narrow and harden. Although experts donât know for sure what starts atherosclerosis, the process seems to stem from damage to the arterial wall.This damage, which enables the deposition of plaque, may result from: HDL is believed to remove some of the bad cholesterol from plaque in clogged arteries and transport it back to the liver, where it is eliminated. 2  High blood pressure. 3  Having high blood pressure increases the rate at which arterial plaque builds up. 4  It also hastens the hardening of clogged arteries. 5  Cigarette smoke.
1 Peripheral artery disease is due to atherosclerosis. 2  This is a gradual process in which a fatty material builds up inside the arteries. 3  The fatty material mixes with calcium, scar tissues, and other substances and hardens slightly, forming plaques of arteriosclerosis.ther causes of peripheral vascular disease include the following: 1  Blood clot: A blood clot can block a blood vessel (thrombus/ emboli). 2  Diabetes: Over the long term, the high blood sugar level of persons with diabetes can damage blood vessels. 3  This makes the blood vessels more likely to become narrowed or weakened.
