Summary
Motor deficits in lacunar stroke patients can progress, particularly in those with diabetes or severe initial motor impairment. This progression is linked to poorer functional outcomes post-stroke.
Area of Science:
- Neurology
- Stroke Medicine
- Clinical Neuroscience
Background:
- Lacunar infarction can lead to progressive neurological deficits.
- Predictors and underlying causes of lacunar stroke progression remain unclear.
Purpose of the Study:
- To investigate the clinical characteristics of motor deficit progression in lacunar stroke patients.
- Identify factors associated with the progression of motor deficits following lacunar infarction.
Main Methods:
- Evaluated 92 patients with first-ever supratentorial lacunar strokes.
- Defined progressive lacunar infarction by motor deficit worsening between admission and the following day.
- Compared progressive versus stable lacunar infarction groups.
Main Results:
- 27% of patients experienced motor deficit progression.
- Diabetes mellitus and admission motor deficit severity independently predicted progression.
- Progressive infarction was associated with larger infarct size and worse functional outcome at discharge.
Conclusions:
- Progression of motor deficits in lacunar stroke correlates with poorer functional outcomes.
- Diabetes and initial motor deficit severity are potential predictors of motor deficit progression.
