[13] [14] [15] Hemorrhagic stroke is caused by either bleeding directly into the brain or into the space between the brain's membranes. [13] [16] Bleeding may occur due to a ruptured brain aneurysm. [13] Diagnosis is typically based on a physical exam and supported by medical imaging such as a CT scan or MRI scan. [9]

The primary goals of stroke management are to reduce brain injury and promote maximum patient recovery. Rapid detection and appropriate emergency medical care are essential for optimizing health outcomes. [1] When available, patients are admitted to an acute stroke unit for treatment.
Researchers examined all studies between 1984 and 2024 which reported on survival or nursing home admission for people with dementia. A total of 235 studies reported on survival among more than 5. ...
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).
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
In the brain, hypertensive encephalopathy - characterized by hypertension, altered mental status, and swelling of the optic disc - is a manifestation of the dysfunction of cerebral autoregulation. Cerebral autoregulation is the ability of the blood vessels in the brain to maintain a constant blood flow. People with chronic hypertension can ...
Derived from Greek roots, the word porencephaly means 'holes in the brain'. [4] The cysts and cavities (cystic brain lesions) are more likely to be the result of destructive (encephaloclastic) cause, but can also be from abnormal development (malformative), direct damage, inflammation, or hemorrhage.
