Insular lesions and smoking cessation after first-ever ischemic stroke: A 3-month follow-up

Little is known about biological factors involved in post-stroke smoking cessation. A recent retrospective study has indicated a possible association between unilateral insular lesions of various origin and a rapid disruption of nicotine addiction. Given the above, the aim of the present prospective...

Description
Summary:Little is known about biological factors involved in post-stroke smoking cessation. A recent retrospective study has indicated a possible association between unilateral insular lesions of various origin and a rapid disruption of nicotine addiction. Given the above, the aim of the present prospective study was to assess a relationship between post-stroke smoking cessation and lesion localization. Eighty-seven patients with first-ever, unilateral, ischemic stroke who had been active smokers at stroke onset were examined during hospitalization and at 3-month follow-up. No association was found between any specific lesion localization (the insula, operculum, striatum, thalamus, internal capsule, brainstem) and smoking status at the 3-month follow-up visit. Patients with lacunar circulation strokes (LACS) were more likely to be non-smokers at the follow-up examination. No sudden disruption of nicotine addition was observed in patients with insular or other stroke locations. Concluding, post-stroke smoking cessation may not be associated with insular lesions.
