The scope of neurosurgery for elderly people.

Patients treated by a single neurosurgeon over a period of 17 years have been reviewed in order to assess the volume and nature of neurosurgical work performed on patients aged over 65 years. Based on this data we report: (1) The age distribution of the principal neurosurgical conditions, drawing attention to those conditions which are over- and under-represented in elderly patients. (2) A steady increase in the number of patients over 65 admitted over the last 15 years. (3) The numbers and types of neurosurgical operations carried out on elderly patients at the present time compared with 10 years ago. (4) The outcome of first-time surgery for intracranial meningiomas in 144 patients analysed by age. It is clear that a large and increasing proportion of neurosurgical work is carried out on persons over the age of 65. Age by itself appears to be no bar to a good outcome after a major neurosurgical operation provided that the surgery is elective and is not accompanied by a diffuse neurological disturbance.
