A silent lacunar infarction (SLI) is one type of silent stroke which usually shows no identifiable outward symptoms, and is thus termed "silent". Because stroke is a clinical diagnosis (that is, it is defined by clinical symptoms), there is debate about whether SLI are considered to be strokes, even though the pathophysiology is presumably the ...
Symptoms of a brainstem stroke frequently include sudden vertigo and ataxia, with or without weakness. Brainstem stroke can also cause diplopia, slurred speech and decreased level of consciousness. A more serious outcome is locked-in syndrome. [citation needed]
Pediatric stroke is a stroke that occurs in children or adolescents. Stroke affects an estimated 2.5 to 13 per 100,000 children annually. [1] The signs and symptoms of stroke in children, infants, and newborns are different from those in adults. The causes and risk factors of stroke in children are also different from those in adults.

The neurologic signs and symptoms must last longer than 24 hours or the brain infarction is demonstrated, mainly by imaging techniques. [45] Transient ischemic attack (TIA) also called a mini-stroke. This is a condition in which the blood flow to a region of the brain is blocked, but blood flow is quickly restored and the brain tissue can fully ...
Claude's syndrome is a form of brainstem stroke syndrome characterized by the presence of an ipsilateral oculomotor nerve palsy, contralateral hemiparesis, contralateral ataxia, and contralateral hemiplegia of the lower face, tongue, and shoulder. Claude's syndrome affects oculomotor nerve, red nucleus and brachium conjunctivum. [1]
Symptoms of cerebral infarction can help determine which parts of the brain are affected. If the infarct is located in the primary motor cortex, contralateral hemiparesis is said to occur. With brainstem localization, brainstem syndromes are typical: Wallenberg's syndrome, Weber's syndrome, Millard–Gubler syndrome, Benedikt syndrome or others.
Some patients will maintain their memory while developing the behavioral disorders while others will show signs of declarative anterograde amnesia with no signs of behavioral disorders. [4] This seems to be related to the location of the hemorrhages for each individual patient. Particularly, whether the infarct is anterior or bilateral. [5]
The most common neurological manifestations of DADA2 are secondary to vasculitis. Fifty-one percent of patients present with neurologic disease, typically in the form of lacunar stroke. [2] In some patients, stroke can be the first indication of disease. [13] Approximately 50% of patients have some form of immunologic or hematologic disease. [2]
