Background and Purpose We aimed to evaluate factors associated with neurological worsening among patients with lacunar or non‐lacunar infarction admitted within 3 hours and between 3 and 24 hours after stroke onset. Methods All patients admitted to Haukeland university hospital between 2006 and 2016 with acute cerebral infarction on MRI and admission within 24 hours were included. Repeated National Institute of Health Stroke Scale (NIHSS) scoring was performed in all patients whenever possible. Neurological worsening during the hospital stay was defined as NIHSS score increase ≥3 compared to NIHSS score on admission. Results In patients with lacunar infarction admitted within 3 hours of onset, neurological worsening was associated with low NIHSS score on admission, low body temperature, and leukoaraiosis, whereas only internal carotid artery stenosis or occlusion was associated with neurological worsening in non‐lacunar infraction. For patients admitted 3‐24 hours after onset, neurological worsening was associated with low body temperature, high systolic blood pressure, and short time from onset to admission in patients with lacunar infarction, whereas high systolic blood pressure, high NIHSS score on admission, middle cerebral artery occlusion, and high blood glucose were associated with neurological worsening in patients with non‐lacunar infarction (all P  < 0.05). Conclusions Lacunar infarctions with minor neurological deficits within 3 hours of stroke onset are at high risk of neurological worsening especially if concomitant low body temperature and leukoaraiosis.
