In recent years, neurologists, neurosurgeons, and neuro-radiologists have made huge advances in delivering fast treatment after a stroke, preventing countless deaths and disabilities. Sometimes, however, it pays to not wait for an acute event. For example, patients with intracranial atherosclerotic disease (ICAD) — the narrowing of the large vessels of the arteries leading to the brain, putting them at risk for stroke — benefit from early referral to an expert center, in part because the best course of therapy isn’t always clear.
Advances in vascular imaging technology are opening up additional options for stroke prevention and cognitive health. Conditions that reduce the blood flow to the brain, including ICAD and moyamoya disease, can cause recurrent strokes and significant cognitive and neurological impairment. Surgery to re-open or bypass blocked arteries may help, but experience shows that a personalized treatment plan based on imaging and other clinical data is needed to provide patients the best possible outcomes.
