Cerebrovascular Disease and Stroke conditions
Anterior Spinal Artery OcclusionAnterior Spinal Artery Occlusion causes ischemia to the anterior two-thirds of the spinal cord, leading to motor paralysis with preserved dorsal column sensation.Charcot-Bouchard MicroaneurysmCharcot-Bouchard microaneurysms are small vessel dilations linked to chronic hypertension that can rupture, causing intracerebral hemorrhage in deep brain regions.Intraparenchymal HemorrhageIntraparenchymal hemorrhage is bleeding within brain tissue often caused by hypertension, leading to sudden neurological deficits and increased intracranial pressure.Ischemic Stroke (Anterior Cerebral Artery)Ischemic stroke of the anterior cerebral artery causes contralateral leg weakness and sensory loss due to infarction in the medial frontal and parietal lobes.Ischemic Stroke (Anterior Inferior Cerebellar Artery)Ischemic stroke of the anterior inferior cerebellar artery causes lateral pontine syndrome with ipsilateral facial paralysis and hearing loss due to brainstem infarction.Ischemic Stroke (Anterior Spinal Artery)Ischemic Stroke (Anterior Spinal Artery) involves infarction of the anterior two-thirds of the spinal cord causing motor paralysis and loss of pain and temperature sensation below the lesion.Ischemic Stroke (Basilar Artery)Ischemic stroke of the basilar artery causes brainstem dysfunction with symptoms like locked-in syndrome due to impaired blood flow in the posterior circulation.Ischemic Stroke (Lenticulostriate Artery)Ischemic stroke involving the lenticulostriate artery causes sudden motor deficits due to small vessel occlusion affecting the basal ganglia and internal capsule.Ischemic Stroke (Middle Cerebral Artery)Ischemic stroke of the middle cerebral artery causes contralateral hemiparesis and sensory loss, often affecting the face and arm more than the leg.Ischemic Stroke (Posterior Cerebral Artery)Ischemic stroke of the posterior cerebral artery causes infarction in the occipital lobe, leading to visual field deficits and possible thalamic sensory loss.Ischemic Stroke (Posterior Inferior Cerebellar Artery)Ischemic stroke of the posterior inferior cerebellar artery causes lateral medullary syndrome with vertigo, dysphagia, and ipsilateral limb ataxia.Saccular (Berry) AneurysmSaccular Berry aneurysm is a rounded outpouching of a cerebral artery wall, often at vessel bifurcations, that can rupture causing subarachnoid hemorrhage.Subarachnoid HemorrhageSubarachnoid hemorrhage is bleeding into the brain's subarachnoid space, often caused by ruptured aneurysms and presenting with sudden severe headache.Transient Ischemic Attack (TIA)Transient Ischemic Attack (TIA) causes temporary neurological deficits due to brief cerebral ischemia without permanent infarction, often signaling stroke risk.
