Presentation
Hemi-anopsia was the presenting symptom in 4 (57%) of the 7 patients with occipital stroke. Table 2. [ahajournals.org]
Several predictors of the delayed AIS diagnosis were identified in the present study. Efforts to target these predictors can reduce diagnostic delays and optimize the management of AIS in children. [ncbi.nlm.nih.gov]
Most of the patients presented with motor involvement (79%) and seizures (45%). Patients presented less frequently with consciousness impairment (15%) and headache (10%). [journals.sagepub.com]
No identifiable RFs was present in 54 (9%). [onlinelibrary.wiley.com]

For all 42 cases, the most frequent etiologies were infections (38.1%, n = 16), iron deficiency anemia (16.7%, n = 7), and moyamoya syndrome (11.9%, n = 5). [ncbi.nlm.nih.gov]
Sickle cell anemia may cause cerebral ischemia linked with the irregularly shaped blood cells. Sickle shaped blood cells clot more easily than normal blood cells, obstructing blood flow to the brain. [columbianeurosurgery.org]

Only two complications were noted: asymptomatic intracerebral hemorrhage and mucosal bleeding. Five patients developed malignant middle cerebral artery infarctions. [reliasmedia.com]
It is likely that the total incidence of perinatal stroke is much higher than these quoted statistics since some children who are asymptomatic in the newborn period are later identified as having a presumed neonatal stroke by imaging when they present [pediatricneurologybriefs.com]

- Hypotension
Hypertension or postural hypotension may have been a precipitating factor. Hypotension may occur because of shock (circulatory collapse). Increased ICP may occur because of tissue edema or clot formation. [nurseslabs.com]

Other causes Any factor that impairs systemic perfusion (eg, carbon monoxide toxicity, severe anemia or hypoxia, polycythemia, hypotension) increases risk of all types of ischemic strokes. [merckmanuals.com]
Other childhood cerebrovascular disorders that were excluded included transient ischemic attack without infarction, hypotensive watershed injury, reversible hypertensive leukoen-cephalopathy, diffuse hypoxic encephalopathies, and asymptomatic infarction [jkns.or.kr]
Decreased perfusion of the brain occurs when blood flow to it is partially or completely restricted (e.g., compression of arterial flow in near-hanging or near-strangulation), when blood pressure is very low (e.g., hypotensive or hemorrhagic shock), or [internationalbrain.org]

- Seizure
Younger children were more likely to present with seizures at stroke ictus, and acute symptomatic seizures were predictive of later RSS and epilepsy in CAIS. [ncbi.nlm.nih.gov]

Neglected tumours may reach large proportions. More examples of dermatofibrosarcoma protuberans How is dermatofibrosarcoma protuberans diagnosed? The absence of symptoms often leads to a delay in diagnosis of d ermatofibrosarcoma protuberans. [dermnetnz.org]
Consequently, patients frequently tend to neglect their problem and presentation can be late. Most patients have this tumor either as a stable lesion or growing over years. [ncbi.nlm.nih.gov]
Not surprisingly, this tumor's indolent behavior was often the cause for initial neglect. Therefore, in many cases, treatment was sought only after the onset of symptoms. [acsjournals.onlinelibrary.wiley.com]
