Perisylvian syndrome is a rare neurological disease characterized by damage to the sylvian fissure (lateral sulcus), an area in the brain involved in language and speech. . The main symptoms are difficulty chewing and swallowing, low muscle tone in the face and tongue, speech and language development disorders, and epile
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]
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.

Watershed stroke symptoms are due to the reduced blood flow to all parts of the body, specifically the brain, thus leading to brain damage. Initial symptoms, as promoted by the American Stroke Association, are FAST, representing F = Facial weakness (droop), A = Arm weakness (drift), S = Speech difficulty (slur), and T = Time to act (priority of intervention).
Wernicke's area, more precisely defined, spans the posterior part of the superior temporal gyrus (STG) and extends to involve adjacent areas like the angular gyrus and parts of the parietal lobe reflecting a more intricate neuroanatomical network than previously understood.
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
In 1949, the idea that WE lesions are a result of a disruption to the blood-brain barrier was introduced. [53] Large proteins passing into the brain can put neurological tissue at risk of toxic effects. The blood-brain barrier junctions are typically found to have WE lesions located at that region of the brain. [53]
