The Hunt and Hess scale, introduced in 1968, is one of the grading systems used to classify the severity of a subarachnoid hemorrhage based on the patient's clinical condition. It is used as a predictor of patient's prognosis/outcome, with a higher grade correlating to lower survival rate.
This is often a result of secondary injury, which can damage neurons that were unharmed in the primary injury. It occurs after a variety of brain injury including subarachnoid hemorrhage, stroke, and traumatic brain injury and involves metabolic cascades. [13] Secondary injury can result from complications of the injury. [1]
If an aneurysm ruptures, blood leaks into the space around the brain. This is called a subarachnoid hemorrhage. Onset is usually sudden without prodrome, classically presenting as a "thunderclap headache" worse than previous headaches. [11] [12] Symptoms of a subarachnoid hemorrhage differ depending on the site and size of the aneurysm. [12]
Detecting small amounts of hemorrhage (diffuse axonal injury pictured) or calcium. [9] Inversion recovery Short tau inversion recovery: STIR: Fat suppression by setting an inversion time where the signal of fat is zero. [10] High signal in edema, such as in more severe stress fracture. [11] Shin splints pictured: Fluid-attenuated inversion ...
The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and sometimes a hemorrhagic stroke. [2] Hypertension (high blood pressure) is the most important contributing risk factor for stroke and cerebrovascular diseases as it can change the structure of blood vessels and result in atherosclerosis .

Intraventricular hemorrhage (IVH), also known as intraventricular bleeding, is a bleeding into the brain's ventricular system, where the cerebrospinal fluid is produced and circulates through towards the subarachnoid space. It can result from physical trauma or from hemorrhagic stroke.
Overall, the development of post-stroke depression can play a significant role in a patient's recovery from a stroke. The severity of post-stroke depression has been associated with severity of impairment in activities of daily living (ADLs). By effectively treating depression, patients experience a greater recovery of basic ADLs such as ...
