Hardening and narrowing of arteries in the brain that may reduce blood flow and cause cognitive or neurological problems.
The type of evidence that matters depends on which path your rating follows. For any rating under this code, medical records must show a diagnosis of cerebral arteriosclerosis supported by the full clinical picture — not retinal findings alone. Imaging studies, vascular assessments, and clinical exam notes that document the basis for the diagnosis are important for this reason. If you have specific neurological disabilities such as paralysis, records showing the type, extent, and cause of that paralysis help establish which hyphenated diagnostic code applies. If your symptoms are purely subjective — headache, dizziness, tinnitus, insomnia, or irritability — medical records that link those symptoms directly to a confirmed diagnosis of cerebral arteriosclerosis support a 10 percent rating under code 9305. If you also have a diagnosis of multi-infarct dementia with cerebral arteriosclerosis, records documenting cognitive and functional impairment become relevant to ratings above 10 percent. Statements from you or people who know you describing how these symptoms affect your work and daily life can help show the connection between the diagnosis and your functional limitations.
