Objective: The ageing process in our society has a particular influence in general medical as well as in neurosurgical interests. It seems that the proportion of further diseases while primary neurological or neurosurgical diagnosed is rising. Is there an influence of rising mean age in therapy of spontaneous subarachnoid haemorrhage? Are diagnostic or therapeutic methods influenced as well? Is there a change of outcome due to possible influencing?

Methods: In the period of 1983 to 1999 the distribution of age, sex, outcome and angiographic findings were compared in 1653 patients diagnosed with spontaneous subarachnoid haemorrhage.

Results: While significant increasing of mean age from 50.05 to 56 years, proportion of elderly patients (≥65 years) rose from 12.8% to 23.6%. Although proportion of fatal outcome could be decreased from 26.6% to 16.6%, proportion of fatal ends in elderly patients (≥65 years) rose in both sexes from 3.8% to 15.1%. Total proportion of angiographies without detected bleeding source decreased to 18.5%. Among the elderly patients (≥65 years) this decrease had the major impact in female patients with less than 10%.

Conclusions: In our opinion presented results are influenced by rising mean age of society. Further a possible influence is represented by the greater awareness in diagnostics and greater indications in subarachnoid haemorrhage.
