Hypertensive encephalopathy ( HE) is general brain dysfunction due to significantly high blood pressure. [ 3] Symptoms may include headache, vomiting, trouble with balance, and confusion. [ 1] Onset is generally sudden. [ 1] Complications can include seizures, posterior reversible encephalopathy syndrome, and bleeding in the back of the eye ...
A hypertensive urgency is a clinical situation in which blood pressure is very high (e.g., 220/125 mmHg) with minimal or no symptoms, and no signs or symptoms indicating acute organ damage. [ 1][ 2] This contrasts with a hypertensive emergency where severely high blood pressure is accompanied by evidence of progressive organ or system damage. [ 1]
In addition, hypertension precedes heart failure in 90% of cases, [7] and the majority of heart failure in the elderly may be attributable to hypertension. [17] Hypertensive heart disease was estimated to be responsible for 1.0 million deaths worldwide in 2004 (or approximately 1.7% of all deaths globally), and was ranked 13th in the leading ...
Labile hypertension occurs when there are unexpected changes in blood pressure. The term can be used to describe when people have blood pressure measurements that abruptly fluctuate from being abnormally high, approximately 140/90 mm Hg or over and returns to its normal range. [ 1]
Hypertensive crisis. Severely elevated blood pressure (equal to or greater than 180 mmHg systolic or 120 mmHg diastolic) is referred to as a hypertensive crisis (sometimes termed malignant or accelerated hypertension), due to the high risk of complications. People with blood pressures in this range may have no symptoms, but are more likely to ...
Central hypoventilation syndrome. Central hypoventilation syndrome ( CHS) is a sleep-related breathing disorder that causes ineffective breathing, apnea, or respiratory arrest during sleep (and during wakefulness in severe cases). CHS can either be congenital (CCHS) or acquired (ACHS) later in life. The condition can be fatal if untreated.
Many report lightheadedness (a feeling that one might be about to faint), sometimes severe, or even actual fainting with associated fall risk. [9] [10] [11] With chronic orthostatic hypotension, the condition and its effects may worsen even as fainting and many other symptoms become less frequent. Generalized weakness or tiredness may also occur.
Intraparenchymal hemorrhage ( IPH) is one form of intracerebral bleeding in which there is bleeding within brain parenchyma. The other form is intraventricular hemorrhage (IVH). [ 1] Intraparenchymal hemorrhage accounts for approximately 8-13% of all strokes and results from a wide spectrum of disorders. It is more likely to result in death or ...
