Intracerebral hemorrhage (ICH), also known as hemorrhagic stroke, is a sudden bleeding into the tissues of the brain (i.e. the parenchyma), into its ventricles, or into both.[3][4][1] An ICH is a type of bleeding within the skull and one kind of stroke (ischemic stroke being the other).[3][4] Symptoms can vary dramatically depending on the severity (how much blood), acuity (over what timeframe), and location (anatomically) but can include headache, one-sided weakness, numbness, tingling, or paralysis, speech problems, vision or hearing problems, memory loss, attention problems, coordination problems, balance problems, dizziness or lightheadedness or vertigo, nausea/vomiting, seizures, decreased level of consciousness or total loss of consciousness, neck stiffness, and fever.[2][1]
Hemorrhagic stroke may occur on the background of alterations to the blood vessels in the brain, such as cerebral arteriolosclerosis, cerebral amyloid angiopathy, cerebral arteriovenous malformation, brain trauma, brain tumors and an intracranial aneurysm, which can cause intraparenchymal or subarachnoid hemorrhage.[1]
The biggest risk factors for spontaneous bleeding are high blood pressure and amyloidosis.[2] Other risk factors include alcoholism, low cholesterol, blood thinners, and cocaine use.[2] Diagnosis is typically by CT scan.[1]
Treatment should typically be carried out in an intensive care unit due to strict blood pressure goals and frequent use of both pressors and antihypertensive agents.[1][5] Anticoagulation should be reversed if possible and blood sugar kept in the normal range.[1] A procedure to place an external ventricular drain may be used to treat hydrocephalus or increased intracranial pressure, however, the use of corticosteroids is frequently avoided.[1] Sometimes surgery to directly remove the blood can be therapeutic.[1]
Cerebral bleeding affects about 2.5 per 10,000 people each year.[2] It occurs more often in males and older people.[2] About 44% of those affected die within a month.[2] A good outcome occurs in about 20% of those affected.[2] Intracerebral hemorrhage, a type of hemorrhagic stroke, was first distinguished from ischemic strokes due to insufficient blood flow, so called "leaks and plugs", in 1823.[6]
