The pattern of cognitive deficits in the chronic state after subarachnoid hemorrhage

  • B. O. Hütter


In connection with the first attempts to exclude an intracranial aneurysm from circulation, already Goldflam (1923) found that SAH leads to specific neuropsychological and psychopathological symptoms, but not to an impairment of general intelligence. A report from Logue et al. (1968) stems from the early days of aneurysm surgery, even before the introduction of the operating microscope and modern intensive care management. Despite the oftentimes drastic consequences of surgery and the untreatable secondary complications, the authors found a normal level of intelligence in the surviving patients. Also in many later studies, substantial cognitive deficits in patients after SAH were found, but in all studies the average intelligence quotient (IQ) was in the normal range (Hütter, Gilsbach and Kreitschmann, 1995; Hütter and Gilsbach, 1993; Säveland et al., 1992; 1986; Ljunggren et al., 1985; Auer, Gallhofer and Auer, 1985; Sengupta, Chinu and Brierley, 1975). In a follow-up study by Sengupta, Chinu and Brierley (1975), as well as in a study by Auer, Gallhofer and Auer (1985), unremarkable IQ mean values were found in the Wechsler Intelligence Test in patients after aneurysm rupture. On the other hand, a large number of patients in both samples complained of decreased general performance capacity, increased irritability and a substantial loss of initiative.
