Final answer:
The best strategy to help stave off the vascular component of a neurocognitive disorder is to maintain normal blood pressure, avoid illicit drugs, seek timely treatment for strokes, and undergo rehabilitation therapy.
Step-by-step explanation:
The BEST strategy for helping stave off the vascular component of a neurocognitive disorder is to keep blood pressure within the normal range. High blood pressure is the main risk factor for stroke, so maintaining normal blood pressure through lifestyle changes and medication is crucial in reducing the risk of stroke. Additionally, avoiding illicit drug use, such as amphetamines or cocaine, can also help prevent strokes.
In cases where a stroke has occurred, timely treatment is essential. Ischemic strokes can be treated with clot-busting drugs if administered within 3-4 hours of the stroke, which may prevent permanent brain damage. Physical, occupational, and speech therapy can also aid in the recovery and relearning of lost functions.
