Blood pressure targets, medication considerations and special concerns in elderly hypertension III: Focus on stroke and neurodegenerative disorders

Controlling hypertension has become an important issue in the elderly population in whom neurological comorbidities are highly prevalent. Most of the large-scale trials focusing on hypertension management in older populations have excluded patients with comorbid neurological disorders. However, this population requires special considerations, as the benefits of antihypertensive agents are mostly uncertain and there is a higher risk of adverse events. In this review article, we discuss current evidence regarding the management of elderly patients with hypertension and common neurological disorders, including stroke and neurodegenerative diseases. In elderly patient with a history of stroke, the blood pressure management strategy is generally similar to that for young patients, however the benefits of stroke prevention from blood pressure control are less significant. For patients with neurodegenerative disorders such as cognitive dysfunction and Parkinson's disease, achieving adequate blood pressure control may be beneficial in reducing cardiovascular risks, although the higher risk of adverse events from antihypertensive treatment may offset some of these benefits. Special considerations for factors such as orthostatic hypotension, risk of falls, polypharmacy, and significant drug-drug interactions are required but frequently neglected in clinical practice. More efforts are warranted to determine the optimal treatment strategy for elderly populations with neurological disorders.
