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.

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 .
Reversible cerebral vasoconstriction syndrome (RCVS, sometimes called Call-Fleming syndrome) is a disease characterized by a weeks-long course of thunderclap headaches, sometimes focal neurologic signs, and occasionally seizures. [1] Symptoms are thought to arise from transient abnormalities in the blood vessels of the brain. [1]
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 ...
Sneddon's syndrome is a progressive, noninflammatory arteriopathy leading to the characteristic skin condition and to cerebrovascular problems, including stroke, transient ischemic attack (TIA), severe but transient neurological symptoms thought to be caused by cerebral vasospasm, coronary disease and early-onset dementia.
Middle cerebral artery syndrome is a condition whereby the blood supply from the middle cerebral artery (MCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the lateral aspects of frontal, temporal and parietal lobes, the corona radiata, globus pallidus, caudate and putamen.
[15] [16] [17] These children are at significant risk of cognitive impairment and poor educational outcomes. [18] Thalassemia major: is an autosomal recessive genetically inherited form of hemolytic anemia, characterized by red blood cell (hemoglobin) production abnormalities. Children with this disorder are at increased risk for silent stroke ...
Depending on the type and severity of encephalopathy, common neurological symptoms are loss of cognitive function, subtle personality changes, and an inability to concentrate. Other neurological signs may include dysarthria, hypomimia, problems with movements (they can be clumsy or slow), ataxia, tremor. [6]
