There are two major types of hypertensions. The majority of people who have hypertension fall into the category of primary hypertension. The cause of their high blood pressure is unknown. Here are descriptions and causes of both primary and secondary hypertension.
1. Essential or primary hypertension is high blood pressure that has no known secondary cause. This type of hypertension is diagnosed after a doctor notices that your blood pressure is high on three or more visits and eliminates all other causes of hypertension. Usually people with essential hypertension have no symptoms. Although there is no known cause for this type of hypertension researchers know that heredity, smoking, alcohol, and diet are all contributing factors to essential hypertension.
2. Secondary hypertension can be caused by conditions that affect your kidneys, arteries, heart or endocrine system. Other causes include airway obstruction during sleep, diseases, and tumors of the adrenal glands, hormone abnormalities, thyroid disease, and too much salt or alcohol in the diet.

Intracranial hypertension is a condition due to high pressure within the spaces that surround the brain and spinal cord. These spaces are filled with cerebrospinal fluid which cushions the brain from mechanical injury, provides nourishment, and carries away waste. The most common symptoms of intracranial hypertension are headaches and visual loss, including blind spots, poor peripheral vision, and temporary blindness. Some patients experience permanent vision loss. Other symptoms include ringing in the ears, neck pain, and shoulder pain.
