I67: Other cerebrovascular diseases

I67.3: Progressive vascular leukoencephalopathy

Many blood vessels supply oxygen to the brain. Certain factors can damage the small blood vessels in the brain. These include, for example, high blood pressure, obesity and smoking. When fats and calcium are deposited in the vascular wall, the blood vessel can get narrower. Then sometimes not enough blood can flow through any longer. At the same time, the wall of the blood vessel may get weaker. In this way, small bleeds can occur in the brain. These circulatory disorders have damaged nerve fibers in your brain.

Various symptoms can appear over a period of time. For example, one’s memory may get worse or one might get confused more often. One may have problems with moving, or in carrying out certain activities.
