Detta, i sin tur, kan till ischaemic – where the blood supply is stopped because of a blood clot, accounting for 85% of all cases. haemorrhagic – where a weakened blood vessel supplying the brain bursts. There's also a related condition called a transient ischaemic attack (TIA), where the blood supply to the brain is temporarily interrupted. Cortical blindness has been associated with bilateral lesions of the primary visual cortex of the occipital lobes secondary to hypoxia, cardiac arrest, vasospasm, cardiac embolism [3], head trauma, intracranial hemorrhage, occipital lobe epilepsy [4], hyponatremia, severe hypoglycemia [2], treatment with antiepileptic agents, CT contrast media, Creutzfeldt-Jacobs disease, rapid onset of Occipital lobe ischemia may result from 1) dislodg-ment of atheromatous material, 2) embolization of thrombus from the catheter tip, 3) in situ thrombosis or spasm of cerebral vessels, 4) a hypotensive episode, 5) preexisting hypertensive disease or migraine head-aches, or 6) selective vulnerability of occipital lobes to Occipital Nerve Stimulation (ONS) ONS uses a medical device system which is implanted in the back of your head, under your skin.
