Objective To prospectively compare recovery outcomes, presentation with NIH stroke scale and modified ranking scale (MRS) in the study population with follow up at discharge.

Background Earlier studies suggested lacunar stroke has a better prognosis compared to other strokes, but recent studies show prognosis of lacunar stroke is simiar or worse when compared to large strokes.

Design/Methods We prospectively collected demographic information, admission NIH stroke scale, and modified ranking scale with serial measurements during hospitalized course in single tertiary care hospital in six-month period(n=74). We also collected information on discharge disposition between lacunar and non-lacunar stroke groups. Two groups adjusted for sex and race. Independent t-test is used for comparing continuous variables and chi-square test for comparing categorical variables.

Results There were 30 lacunar stroke patients and 44 non-lacunar stroke patients with mean age of 60 years for lacunar stroke patients and 70 for non-lacunar stroke patients. Mean admission NIH stroke scale was 11 in the non-lacunar group with MRS of 0.4 compared to 6 (p= 0.009) and 1(p=0.006), respectively in the lacunar group. Discharge NIH and MRS values were 7 and 2.3 respectively for the non-lacunar group compared to 4(p=0.03) and 2.2(p=0.88) for the lacunar group. ΔNIH (admit-discharge) is 4 and 2 for non-lacunar and lacunar group, respectively. ΔMRS (admit-discharge) is –1.9 and –1.3 for non-lacunar and lacunar group, respectively. Discharge to home was 46.7% & 37% (p=0.03) in non-lacunar group and lacunar group, respectively. Discharge to Skilled nursing facility was 13.3% and 18.5%(p=0.03) in non-lacunar group and lacunar group, respectively.

Conclusions Despite the relatively small volume of infarct associated with lacunar stroke compared to typically large infarcts seen with non-lacunar stroke, we found that the outcome was similar if not worse in terms of recovery for lacunar type stroke based upon prospective information collected in our six-month database extending from May 2021 to November
