Cerebral stroke caused by intracerebral hemorrhage is serious. This review presents updated knowledge about the condition. ⋯ Intracerebral hemorrhage strikes about 1,000 persons in Norway annually. Hypertension is the single most important risk factor. Cerebral CT confirms the diagnosis. Almost half of the patients die during the first month after the hemorrhage, many during the first two days. About 20% of the patients can manage without help after the first six months. Treatment includes measures against increased intracranial pressure and in selected cases surgical evacuation of the haematoma, especially in cases of bleeding into the cerebellum. Recombinant factor VIIa infused within the first three hours to stop the bleeding can play an important role in the acute phase. Patients below the age of 45, patients without hypertension, and patients with lobar haemorrhage and signs of clinical deterioration should be thoroughly investigated to disclose a potential arteriovenous malformation or an aneurysm. Neurointensive care may give better clinical results and the condition should ideally be treated in an intensive care unit.

Subarachnoid haemorrhage (SAH) causes 3% of all strokes and is caused by a ruptured cerebral aneurysm in four of five cases. This review article presents an update of knowledge on symptoms, diagnosis and management of SAH. ⋯ The mortality of SAH is approximately 50% and one out of three survivors have permanent disabling neurological symptoms. Patients with suspected or diagnosed SAH need urgent examination and treatment. A large randomised multicentre study (International Subarachnoid Aneurysm Trial) suggests that endovascular repair with coiling may be less traumatic than microsurgery. Not all patients are suitable for endovascular treatment, despite new tools like balloon- and stent-assisted coiling. Centres that treat patients with SAH should have both methods available at all hours. The management of these patients involves advanced neuro-intensive care, and co-operation between neurosurgeons, neuroradiologists and neuroanestesiologists.
