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
Prognosis and treatment are determined by location and size of the hemorrhage. [5] Subarachnoid hemorrhage is most commonly caused by the rupture of an aneurysm, usually at the base of the brain. Prior to rupture, Diffuse hemorrhage from the alveoli in the lungs; symptoms include headache, diplopia or blurred vision.
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.
Symptoms: Headache, confusion, paralysis [1] Usual onset: Rapid [2] Causes: Head injury, bleeding disorder, blood vessel malformation [1] Diagnostic method: Medical imaging (CT scan) [1] Differential diagnosis: Subdural hematoma, subarachnoid hemorrhage, traumatic brain injury, [1] transient ischemic attack seizure, intracranial abscess, brain ...
If treatment is not received, this bleeding can cause long-term problems such retinal detachment or scarring in addition to impairing eyesight. The underlying pathology originates in the brain and usually involves an intracranial hemorrhage, such as a subarachnoid hemorrhage (SAH), or several types of elevated intracranial pressure.
The most common cause of a subarachnoid hemorrhage is an aneurysm rupture due to the weakened blood vessel walls and increased wall stress. [48] The neurologic symptoms are produced by the blood mass effect on neural structures, from the toxic effects of blood on the brain tissue, or by the increasing of intracranial pressure. [49]
Subarachnoid hemorrhage is an extremely serious condition in which a neural membrane is breached and the brain itself is compromised. The onset is sudden, described as "the worst headache of one's life," and many grave symptoms follow.
