Clinical presentation varies depending on location, acuity, and severity of<unk> . More gradual onset of symptoms or<unk>  allows for compensatory collateral<unk>  system to develop
Symptoms are variable and may not all be present
Headache 74-92%
Usually progresses during a period of hours or days to severe aching or throbbing over the entire cranium, bifrontally, or at the vertex.
Pain at the vertex of the cranium is infrequent but more specific.
Coughing, bending over, or head movements tend to worsen headaches.
Seizures 35-50%
Usually focal convulsions
Papilledema 28-45%
Focal neurologic sequelae
Occurs hours to days after headache in about half of patients
dizziness) 25-71%
Encephalopathy

Although presentation can be highly variable, neuro deficits can be correlated with the location of the occlusion
