Without proper treatment, patients with ruptured aneurysms have limited functional survival. It has been estimated that only 18 percent are functional survivors at 10 years and 8 percent are disabled, the rest die (Vinas and Wilner, 2008). Thus, it can be said that aneurysms of brain have potential to cause death, debility and deformity.
The risk factors can be inherited or acquired (Vega et al, 2002). The disease can occur as familial clustering with no other hereditary disease in the family. The cause for this is not yet known. Research has shown that the incidence of brain aneurysms is about 8-9 percent in those with more than one relative suffering from either an aneurysm or subarachnoid hemorrhage (Vega et al, 2002). Also, there are reports that siblings of affected individuals have higher chances of developing subarachnoid hemorrhage due to aneurysms. Thus it can be said that aneurysm has generic and hereditary links. It has been proposed that certain hereditary connective tissue disorders are associated with the development of aneurysms because of weakening of the vascular walls (Vinas and Wilner, 2008). Some research has shown that 10- 15 percent of patients with autosomal dominant condition polycystic kidney disease develop intracranial aneurysms (Vega et al, 2002). However another connective tissue disorder Marfans syndrome which was incriminated in the development of brain aneurysms is no longer found to be associated with aneurysms (Vega et al, 2002). Other conditions which have been reported to be associated with brain aneurysms are fibromuscular dysplasia, coarctation of aorta and pheochromocytoma. It has been thought that the elevated blood pressure in these conditions is the cause for the development of aneurysms. Other inherited risk factors which have been incriminated in the development of aneurysms include alpha-glucosidase deficiency, Noonans syndrome, tuberous sclerosis, Klineflters syndrome, alpha-1

From a few minutes to the next few hours of the initial incident, a space-occupying effect would become apparent with blood filling, distorting, and compressing of the surrounding tissue (Chakrabarty and Shivane, 2008). An increased intracranial pressure would be seen, including brain stem compression.
As the author of the essay puts it, the split-brain patient’s two hemispheres are separated in that their left hemisphere does not recognize what the left hemisphere is doing. Notably, each hemisphere functions differently since it is conscious of its own, and both the right and left hemispheres may be conscious simultaneously distinct.
(Pearce, 2011) .In many cases the dilation stretches out from a local area but it can also involve the whole circumference (Reed D, Reed C, Stemmermann and Hayashi, 1992). Aneurysms forms when blood pressure passes through a degraded or injured part of artery thus causing the vessel to bulge outward eventually forming a balloon like extension.
The force of blood pumped from the heart towards the arteries for supply to the entire body causes balloon-like swellings at the weakened areas, which is known as an aneurysm (National Institute of Health, 2011).
Diagnosis at present is based on the clinical history, and the physical examination findings of the examiner. Confirmation of the diagnosis is made easier by the more sensitive, specific and accurate imaging techniques of our times. In its pathogenesis, articles have shown no sole explanation for its occurrence.
Population based studies have indicated that the incidence of SAH in the United Kingdom is around 10 cases per 100,000 of population on an annual basis. The traditional treatment of SAH used to be neurosurgical clipping which involved surgically opening up the cranium in
s out the function of sending the information from one hemisphere of the brain to the other one which will be responsible for the carrying out of that activity. There are certain activities that can be done by both the hemispheres and it is the function of the corpus callosum to
An example related to lifestyle has been given whereby two populations of the elderly were studied by researchers. The tow population included sedentary and active. The findings were that the cognitive was greatly influenced. Exercise was observed to influence executive function positively and quantitative skills were positively affected.
