Aneurysms seizures

Moyamoya seems to be mainly confined to the Japanese and other Asians, and in most cases the cause is unknown (Bruno et al. 1988 Chiu et al. 1998). Some cases are familial (Kitahara et al. 1979) others appear to be caused by a generalized fibrous disorder of arteries (Aoyagi et al. 1996), and a few may result from a congenital hypoplastic anomaly affecting arteries at the base of the brain, or associated with Down s syndrome (Cramer et al. 1996). The syndrome may present in infancy with recurrent episodes of cerebral ischemia and infarction, mental retardation, headache, epileptic seizures and, occasionally, involuntary movements. In adults, subarachnoid or primary intracerebral hemorrhage are also common owing to rupture of collateral vessels. There have also been a few reports of associated intracranial aneurysms (Iwama et al. 1997) and also of cerebral arteriovenous malformations. 

Arteriovenous malformations present most commonly with signs consistent with a space-occupying lesion or seizures and consist of an abnormal fistulous connection(s) between one or more hypertrophied feeding arteries and dilated draining veins (Clatterbuck et al. 2005) (Fig. 7.5). The blood supply is derived from one cerebral artery or, more often, several, sometimes with a contribution from branches of the external carotid artery. Arteriovenous malformations vary from a few millimeters to several centimeters in diameter. Approximately 15% are associated with aneurysms on their feeding arteries. Some grow during life but a few shrink or even disappear, and some are multiple. These fistulae occur in or on the brain, or in the dura of the intracranial sinuses. 

Headache may be the only symptom in SAH or there may be accompanying symptoms that may also be seen with other causes of sudden-onset headache and so are not diagnostic. Patients are often irritable and photophobic. Loss of consciousness occurs in around half the patients but may only be brief. Nausea and vomiting are less common. Partial or generalized seizures occasionally occur at the onset period since these do not occur in perime-sencephalic hemorrhage or in thunderclap headache, their presence is a strong indicator of aneurysmal rupture (Pinto et al. 1996). 

Copper deficiency Copper imbalance causes health disorders that include arthritis, fatigue, adrenal burnout, insomnia, scoliosis, osteoporosis, heart disease, cancer, migraine headaches, seizures, fungal and bacterial infections, gum disease, tooth decay, skin and hair problems, and female organ conditions including uterine fibroids and endometriosis. Copper deficiency is associated with atherosclerosis and other cardiovascular conditions, aneurysms, gout, and anemia. - - ...
