Reappraisal of Lhermitte's sign in multiple sclerosis.

Lhermitte's sign (LS) is strongly linked to multiple sclerosis (MS). Our aim is to reassess its frequency, natural history, various characteristics and neuroradiological correlation in a cohort of MS patients attending our specialized MS clinic and to propose a working definition. Consecutive patients with CDMS and normal controls were interviewed using a structured questionnaire.

The aim of this controlled cross sectional study was to investigate the prevalence, pattern and severity of autonomic dysfunction in Iraqi MS patients and to correlate them with patient`s age, disease course, duration and severity.
