“…Whereas Adams et al ,32 Hori and Sazuki,33 Fortuny et al ,34 and Stenhouse et al 6 have all reported that postoperative vasospasm was a significant predictor of residual cognitive impairment at variable periods of follow up, Ogden et al ,2 Barbarotto et al ,13 and Hütter and Gilsbach5 failed to find any association between vasospasm and cognitive function. The predictive value of postoperative lesions on imaging for lasting cognitive impairments has also been controversial.…”

Objectives-To determine the frequency and severity of neuropsychological impairments associated with aneurysmal subarachnoid haemorrhage, and associated with repair of intracerebral aneurysms. Methods-Two groups of patients who underwent repair of intracerebral aneurysms were studied: patients with unruptured aneurysms (n=20) and patients with ruptured aneurysms (n=27). All patients were administered a battery of standardised neuropsychological tests about 3 months after surgery. A subset of 12 patients with unruptured aneurysms were administered the battery both before and after elective repair of the aneurysm(s). A subset of six patients with ruptured aneurysms were given the test at both 3 months and 1 year after surgery. Results-As previously reported for patients with ruptured aneurysms, patients with both ruptured and unruptured aneurysms performed, as a group, significantly below published norms on many of the neuropsychological tests after surgery. However, there were significant diVerences between preoperative and postoperative performance in the unruptured aneurysm group only on a few tests: measures of word fluency, verbal recall, and frontal lobe function. Performance of patients with ruptured aneurysms was significantly below that of patients with unruptured aneurysms only on a few tests of verbal and visual memory. In addition, group diVerences compared with published norms reflected severely impaired performance by a minority of patients, rather than moderately impaired performance in a majority of patients. Conclusions-Although patients who undergo repair of ruptured aneursyms perform, as a group, below published norms on many neuropsychological tests, significant impairments are seen in a minority of patients. Some of the impairments are associated with subarachnoid haemorrhage, whereas others (found in patients who underwent repair of unruptured aneurysms) are due to general eVects of neurosurgery and perioperative management. Finally, some of the postoperative deficits are merely a reflection of premorbid weaknesses. (J Neurol Neurosurg Psychiatry 2000;69:608-615)

“…Disability included mild in 10%, partial in 18.8%, moderate in 8.6%, moderately severe in 1.4%, severe in 2.9%, extremely severe in 2.9%, and vegetative state in 1.4%. Overall 74% of patients returned to work after 4 months, 83% of previously unemployed patients returned to baseline, and 25% were disabled 17 . In this study good outcome were observed in 40 cases among them 22 cases (42.3%) were able to return premorbid activities.…”

Introduction:Aneurysms resemble bubbles or focal dilation of arteries that occur at weak points of the artery wall (figure-1). There are many factors for its formation. These factors include genetic predisposition, the anatomy of the artery and its branches, 'wear-andtear' on the wall of the arteries due to blood flow, artery disease and cigarette smoking 1 . Aneurysms are the most common at circle of Willis in the central skull base. Approximately 80% of aneurysms arises from anterior circulation of the brain, while 20% form posterior circulation of the brain 1.2 .It is uncommon to diagnose an aneurysm before it has ruptured and most people with aneurysms are unaware that they have an aneurysm until it bursts. Overall 3.6-6% of normal population has aneurysm, among them 1.4-1.9 % rupture in a year. Women have more tendencies to rupture. There is seasonal variation of rupture 3 .
