Prevalence survey of major neurological disorders in Sicily: results of a pilot study

A pilot study on the prevalence of neurological disorders in Sicily was carried out with a protocol nerve previously used in Italy. A screening questionnaire was administered to 1,601 subjects of a community, designed to identify patients with cerebrovascular diseases, epilepsy, extrapyramidal syndromes, peripheral neuropathies, migraine and intracranial neoplasms. Of 262 subjects who were identified as likely to be suffering from neurological illness, 248 (94.6%) were examined by a neurologist. Of these, 8.9% were found to be normal, 46.8% were suffering from non-neurological diseases, 44.3% had one or more neurological diseases (prevalence of 6.8%). This pilot study proved to be a good starting-point for a future major survey.
