Intracranial hemorrhage; Axiali CT scan of a spontaneous intracranial hemorrhage: Specialty: Emergency medicine Symptoms: Same symptoms as ischemic stroke, but unconsciousness, headache, nausea, stiff neck, and seizures are more often in brain hemorrhages than ischemic strokes: Complications
A CT scan is the best test to look for bleeding in or around your brain. In some hospitals, a perfusion CT scan may be done to see where the blood is flowing and not flowing in your brain. Magnetic resonance imaging (MRI scan) : A special MRI technique ( diffusion MRI ) may show evidence of an ischemic stroke within minutes of symptom onset.
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).
Damage to the defecation centre within the medulla oblongata of the brain can lead to bowel dysfunction. A stroke or acquired brain injury may lead to damage to this centre in the brain. Damage to the defecation centre can lead to a loss of coordination between rectal and anal contractions and also a loss of awareness of the need to defecate. [12]
The outlook for someone with lateral medullary syndrome depends upon the size and location of the area of the brain stem damaged by the stroke. [2] Some individuals may see a decrease in their symptoms within weeks or months, while others may be left with significant neurological disabilities for years after the initial symptoms appear.

Global brain ischemia occurs when blood flow to the brain is halted or drastically reduced. This is commonly caused by cardiac arrest. If sufficient circulation is restored within a short period of time, symptoms may be transient. However, if a significant amount of time passes before restoration, brain damage may be permanent.
Hemorrhagic transformation is a process which involves the bleeding of brain tissue that has been affected by the stroke and can take two forms: petechial hemorrhage and parenchymal hemorrhage. [ 1 ] HT can lead to further damage to the brain tissue and worsen the outcome of the initial stroke.
While this bleeding can result in further injury, it is itself a marker for injury that has already occurred. Most intraventricular hemorrhages occur in the first 72 hours after birth. [9] The risk is increased with use of extracorporeal membrane oxygenation in preterm infants. [10] Congenital cytomegalovirus infection can be an important cause ...
