Clinical and imaging risk factors for early neurological deterioration and long-term neurological disability in patients with single subcortical small infarction.

Introduction: This study aims to evaluate the clinical and imaging risk factors for early neurological deterioration (END) and long-term neurological disability in patients with Single subcortical small infarction (SSSI).

Methods: We retrospectively included SSSI patients hospitalized. Outcomes were defined as modified Rankin Scale (mRS) score > 2 at follow-up and the occurrence of END during hospitalization.
