Abstract:
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.

Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and narrowing...
