Diagnostic Code 8046 · 38 CFR §4.124a
Cerebral arteriosclerosis is the hardening and narrowing of blood vessels in the brain due to plaque buildup, reducing blood flow to brain tissue. This can cause gradual cognitive decline, difficulty with memory and concentration, personality changes, dizziness, and increased risk of stroke. Veterans may develop this condition from years of service-connected hypertension, diabetes, high cholesterol, or exposure to toxic substances that damage blood vessels. The gradual nature of the disease means symptoms often develop slowly and may not be noticed until significant brain damage has occurred.
