The difference between hypertensive crisis and hypertensive encephalopathy
Both hypertensive encephalopathy and hypertensive crisis involve a rapid increase in blood pressure, symptoms of headache, restlessness, nausea and vomiting, palpitations, shortness of breath, and blurred vision, with systolic pressure increasing to 200 mmHg and diastolic pressure to 120 mmHg, typically presenting similar clinical blood pressure readings. The main difference between the two is that hypertensive encephalopathy is based on excessively high blood pressure in patients with severe hypertension. Furthermore, hypertensive encephalopathy can lead to clinical signs of cerebral edema and increased intracranial pressure, whereas hypertensive crisis occurs when blood pressure suddenly rises over a short period, causing symptoms due to excessive secretion of catecholamines driven by increased sympathetic nervous excitement.
