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. [2]
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.

The most frequent presenting signs and symptoms of primary CNS vasculitis were focal neurological defecits (seen in 63% of cases), headaches (51%) and cognitive impairment (41%). [4] Other presenting symptoms include aphasia or other difficulties with speech (35-43%), ataxia , visual field deficits, acute or subacute encephalopathy (which may ...
Signs are typically the same as in other dementias, but mainly include cognitive decline and memory impairment of sufficient severity as to interfere with activities of daily living, sometimes with presence of focal neurological signs, and evidence of features consistent with cerebrovascular disease on brain imaging (CT or MRI). [4] [5]
[7] [8] The incidence is much higher in the elderly, especially those who are 85 or older, who are 9.6 times more likely to have an intracerebral hemorrhage as compared to those of middle age. [8] It accounts for 20% of all cases of cerebrovascular disease in the United States, behind cerebral thrombosis (40%) and cerebral embolism (30%). [9]
Symptoms of SAH include a severe headache with a rapid onset (thunderclap headache), vomiting, confusion or a lowered level of consciousness, and sometimes seizures. [10] CT scan has 100% sensitivity of detecting SAH at 6 to 24 hours after symptoms onset. [3] The diagnosis is generally confirmed with a CT scan of the head.
Signs and symptoms [ edit ] The most frequently observed problems related to a cerebral arteriovenous malformation (AVM) are headaches and seizures , cranial nerve afflictions including pinched nerve and palsy , [ 2 ] [ 3 ] backaches, neckaches, and nausea from coagulated blood that has made its way down to be dissolved in the cerebrospinal fluid .
Aging: the prevalence of silent stroke rises with increasing age with a prevalence rate of over twenty percent of the elderly increasing to 30%-40% in those over the age of 70. [13] Anemia: children with acute anemia caused by medical conditions other than sickle cell anemia with hemoglobin below 5.5 g/dL. are at increased risk for having a ...
