A transient ischemic attack (TIA), commonly known as a mini-stroke, is a temporary (transient) stroke with noticeable symptoms that end within 24 hours. A TIA causes the same symptoms associated with a stroke, such as weakness or numbness on one side of the body, sudden dimming or loss of vision, difficulty speaking or understanding language or slurred speech.
Woman experiencing mini stroke symptoms. Every year, nearly 800,000 people will have a stroke, according to the CDC.Most of these strokes will be what's called "ischemic," which happens when blood ...
The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and sometimes a hemorrhagic stroke. [2] Hypertension (high blood pressure) is the most important contributing risk factor for stroke and cerebrovascular diseases as it can change the structure of blood vessels and result in atherosclerosis.

Antihypertensive therapy seeks to prevent the complications of high blood pressure, such as stroke, heart failure, kidney failure and myocardial infarction. Evidence suggests that a reduction of blood pressure by 5 mmHg can decrease the risk of stroke by 34% and of ischaemic heart disease by 21%.
An optimal blood pressure control is essential to prevent target-organ damage associated with complications of hypertension such as heart failure, ischemic heart diseases, stroke, and renal failure, ultimately reducing the risk of premature mortality. [2] Antihypertensives are classified by different mechanisms or sites of action.
In terms of environmental factors, dietary salt intake is the leading risk factor in the development of hypertension. [7] Salt sensitivity is characterized by an increase in blood pressure with an increase in dietary salt and is associated with various genetic, demographic, and physiological factors— African American populations, postmenopausal women, and older individuals carry a higher ...
Diabetes, a condition where blood glucose levels cannot be controlled, affects more than 10% of the adult population worldwide, and more than 90% of those have type 2 diabetes.
For most people, recommendations are to reduce blood pressure to less than or equal to somewhere between 140/90 mmHg and 160/100 mmHg. [2] In general, for people with elevated blood pressure, attempting to achieve lower levels of blood pressure than the recommended 140/90 mmHg will create more harm than benefits, [3] in particular for older people.
