If healthy blood pressure is no higher than 120/80, but blood pressure is not viewed as a problem until it hits at least 140/90, consider all the damage that is being done before any intervention ...
Diagnostic methods for hypertensive encephalopathy include physical examination, blood pressure measurement, blood sampling, ECG, EEG, chest X-ray, urinalysis, arterial blood gas analysis, and imaging of the head (CAT scan and/or MRI). Since decreasing blood pressure is essential, anti-hypertensive medication is administered without awaiting ...
The effect of treatment of blood pressure between 130/80 mmHg and 160/100 mmHg is less clear, with some reviews finding benefit [6] [16] [17] and others finding unclear benefit. [18] [19] [20] High blood pressure affects 33% of the population globally. [9] About half of all people with high blood pressure do not know that they have it. [9]
