What is intercranial hypertension?

Intracranial HTN: Intracranial hypertension means that the pressure of cerebrospinal fluid within the skull is too high. Brain has the fluid inside and is also surrounded by the fluid. Since the skull is closed any increase in this fluid will cause the pressure to go up. This is very serious. Intracranial hypertension in adults is generally defined as intracranial pressure that reaches 250mmh2o or above. ...Read more

Hypertension (Definition)

A blood pressure reading has two numbers: a systolic blood pressure and a diastolic blood pressure. The systolic blood pressure is the maximum pressure the blood exerts on the vessels when the heart is beating. The diastolic blood pressure is the pressure the blood exerts on the vessels in between heartbeats. Hypertension, or high blood pressure, begins when the systolic blood pressure remains above 140 or when the diastolic blood pressure remains above 90. Hypertension can be a result of increased blood flow through vessels or increased resistance to ...Read more

What is hypertension?

What is hypertension?

Elevated BP: Hypertension is defined as blood pressure above 140/90 (either value). Normal BP is considered 120/80 with pre-hypertension as 120-140/80-90. For pre-hypertension recommendations include improved diet (low salt) and exercise with consideration of an anti-hypertensive medication. Hypertension can lead to problems such as heart attack and stroke and usually does not cause any symptoms. ...Read more

What is idiopathic intracranial hypertension?

What is idiopathic intracranial hypertension?

Unknown cause: Ideopathic means unknown. Pressure in the brain is usually due to tumor or infection. If these are ruled out, the pressure is considered ideopathic. Another term can be pseudo tumor. There can be normal pressure hydrocephalus in the elderly, but reducing "pressure" makes them better. ...Read more

What is systolic hypertension?

High blood pressure: Blood pressure is a systolic number over a diastolic number: the heart never fully goes down to 0 pressure so there is a squeeze pressure and a coast or relax pressure. Systolic hypertension means the top number is too high. ...Read more

What is benign hypertension?

Mild High blood Pres: Basically, that is a way to describe blood pressure elevations, or an elevated blood pressure that is not immediately a threat to your life , and is more on the "mild" side.

What is intracranial pressure?

What is intracranial pressure?

Pressure on brain: Intracranial pressure relates to the contents of the skull, including brain, spinal fluid and blood. The pressure will vary with posture and an increase in any of the contents, such as brain swelling from trauma, bleeding or an excessive build up of spinal fluid or blockage in the normal path from formation to exit from the skull. ...Read more

What is idiopathic intracranial hypertension and what causes it ?

Pseudotumor Cerebri: Condition results in abnormal accumulation of too much intracranial fluid, causing headaches, changes in visual acuity, and obscurational attacks. It seems related to obesity, menstrual and hormonal dysfunction, cerebral vein obstruction, toxins such as high levels of vitamin A, certain antibiotic reactions, and more, BUT not clear why the system fails. Diamox (acetazolamide) and brain shunting may help. ...Read more

What is reno vascular hypertension?

What is reno vascular hypertension?

Kidney artery: Kidneys are critical regulators of salt balance and bp, and when a partial renal arterial obstruction develops, the level of BP sensed by the kidney decreases. This trigger a number of processes, notably increased secretion of renin, which raise systemic bp, resulting in hypertension. Renovascular hypertension can sometimes be improved or even cured by relief of the obstruction. ...Read more

What is the difference between arterial hypertension and pulmonary hypertension?

What is the difference between arterial hypertension and pulmonary hypertension?

Peripheral vs Lung: Systemic arterial hypertension or just regular hypertension is elevated pressure in aorta or peripheral circulation (arms, legs). Pulmonary hypertension is elevated pressure in the pulmonary arteries in the lungs. Pulmonary hypertension usually has different causes, prognosis and much different treatment than systemic arterial hypertension. ...Read more
