The cognitive and psychological sequelae of uncomplicated aneurysm surgery.

Neuropsychological course after surgery for intracranial aneurysms. A prospective study and a critical review

“…Although the results of Ogden et al (1993) and the current study are consonant with those reported by Maurice-Williams et al (1991) and Richardson (1991) in so far as the signs of postoperative cognitive dysfunction were generally modest for the sample as a whole, the two former studies, both based on larger samples, suggest a higher occurrence and a longer phase of improvement.…”

“…Similarly, Richardson (1991) found only small changes of cognitive results in a sample of 32 aneurysm patients submitted to neuropsychological assessment at six weeks and six months after surgery. At variance with the results of Maurice-Williams et al (1991). however, Richardson (1991) found that pronounced impairment persisted by six months on verbal fluency and object naming tasks, and that digit span remained unchanged.…”

“…While a few prospective case studies and studies of small groups of patients with unusual sequelae have been published, only three previous studies of representative samples of aneurysm patients appear to have provided detailed results of prospective, repeated, neuropsychological assessments 1 . Maurice-Williams et al, (1991) examined 27 patients and are the first to present results of neuropsychological assessment undertaken preoperatively as well as of early (before discharge) and delayed (at 12 months) postoperative assessments. Most of the tests showed little change by one year after surgery compared to the preoperative and early postoperative assessments.…”

Patient information after ruptured intracranial aneurysm

“…On the contrary, other studies could not find any relationship between side of aneurysm and postoperative performance (De Santis et al. 1989, Maurice‐Williams et al. 1991, Tidswell et al.…”

“…The location of the aneurysm and how this relates to outcome is discussed in the literature, Clinchot et al 1997) found that right-sided lesions were associated with longer rehabilitation and motor impairment. On the contrary, other studies could not find any relationship between side of aneurysm and postoperative performance (De Santis et al 1989, Maurice-Williams et al 1991, Tidswell et al 1995. Anterior communicating artery (AcoA) aneurysmal SAH has been found, in several studies, to be associated with changes in personality, intellectual function, memory and conceptual learning, and with poor social adjustment (Sengupta et al 1975, Okawa et al 1980, Stenhouse et al 1991.…”
