Aneurysm surgeons are familiar with the fact that some patients with a good neurological recovery after a major SAH and aneurysm operation demonstrate a diffuse encephalopathy with emotional or psychological disturbances, which may interfere with their capacity for work and social reintegration. Such disturbances after severe head trauma have been quite extensively studied.4,5,12–14,17,20,23–26 Consequently, it is known that posttraumatic encephalopathy after severe head trauma often results in adverse effects to the cognitive apparatus, causing memory disorders, spatial disorganization, disturbances in reasoning, abstraction, and concept formation, perception difficulties, or other indications of cognitive impairment.
To our knowledge, no similar study has focused on patients who have made a good neurological recovery after rupture and subsequent operation of an intracranial aneurysm, although some studies have touched on the problem.18,21,22 The present study was undertaken to establish the quality of life, to elucidate adaptive patterns in such patients, and to establish the degree and extent of any persistent cognitive impairment found.
