Same symptoms as ischemic stroke, but unconsciousness, headache, nausea, stiff neck, and seizures are more often in brain hemorrhages than ischemic strokes: Complications: Coma, persistent vegetative state, cardiac arrest (when bleeding is in the brain stem or is severe), death: Types
Brain herniation is associated with hyperventilation, extensor rigidity, pupillary asymmetry, pyramidal signs, coma and death. [10] Hemorrhage into the basal ganglia or thalamus causes contralateral hemiplegia due to damage to the internal capsule. [7] Other possible symptoms include gaze palsies or hemisensory loss. [7]
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]
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.
Traumatic brain injury is defined as damage to the brain resulting from external mechanical force, such as rapid acceleration or deceleration, impact, blast waves, or penetration by a projectile. [10] Brain function is temporarily or permanently impaired and structural damage may or may not be detectable with current technology. [11]
The fibrous sutures specifically allow the deformation of the skull during birth [3] and absorb mechanical forces during childhood [6] They also allow the necessary expansion during brain growth. [3] In the very first years of life the sutures serve as the most important centers of growth in the skull. [3]

Symptoms of chronic subdural hematomas are usually delayed more than three weeks after injury. [1] If the bleeds are large enough to put pressure on the brain, signs of increased intracranial pressure or brain damage will be present. [3] Other symptoms of subdural hematoma can include any combination of the following: [7]
