Background and Objectives: Acute ischemic stroke is a major cause of disability and mortality. Cerebrolysin, a neuropeptide with neuroprotective and neurotrophic properties, may enhance post-stroke recovery. This study evaluated the impact of adding Cerebrolysin to standard therapy on clinical outcomes in patients with acute ischemic stroke. Materials and Methods: This non-randomized prospective observational study included 143 adults with acute ischemic stroke at Kovai Medical Center and Hospital, Coimbatore (April 2016–May 2018). Participants were divided into two groups: the standard therapy group (n = 70) and the adjuvant therapy group (n = 73), which received Cerebrolysin (30 mL IV daily for 14 days) in addition to standard care. Stroke severity and functional outcomes were evaluated using the National Institutes of Health Stroke Scale (NIHSS) and Barthel Index (BI) at baseline and Day 14. A p < 0.05 was considered statistically significant. Results: Stroke severity improved in both groups, but the adjuvant group demonstrated significantly greater reductions in NIHSS scores from 9.90 ± 2.90 to 3.40 ± 1.40 compared to the standard group, which improved from 10.10 ± 2.80 to 4.80 ± 1.30 (t = 6.19, p < 0.001). Additionally, 43.84% of patients in the adjuvant group shifted to minor stroke severity versus 25.71% in the standard group. Both groups showed significant improvements across all domains of the BI, which assesses activities of daily living (ADL); however, the gains were consistently greater in the adjuvant group (p < 0.001). A higher proportion of patients in the Cerebrolysin group achieved slight dependency (38.36%) or full independence (16.44%), compared to 20% and 5.71% in the standard group, respectively. Conclusions: This prospective observational study suggests that adding Cerebrolysin to standard therapy was associated with greater neurological recovery and functional independence in acute ischemic stroke patients. However, the short follow-up, single-center setting, and lack of randomization limit generalizability. Larger multicenter randomized trials with longer follow-up are needed to confirm these findings.
