The symptoms will be primarily neurological and associated with convulsions, violent headaches and vomiting. In an extreme state, a loss of consciousness or a coma can occur, just as a massive haemorrhage in the brain, which is then responsible for a hemorrhagic cerebral vascular attack. Sometimes some multiple rises of blood pressure are responsible for small cerebral vascular accidents that will damage the brain in the long term. The treatment of a rise of blood pressure must be carried out in a hospital with a monitoring of the blood pressure.
Antihypertensive therapy is managed by intravenous injection to make the blood pressure lower.
Of course, the doctor will search for the cause of this rise of blood pressure and will also search for the consequences in particular on the brain. If an acute oedema of the lung appears, a diuretic intravenous treatment is prescribed.
