The objective of this observational study is to understand the long-term effects of traditional Chinese medicine (TCM) intervention on patients with cerebral infarction onset within \<48 hours and comorbid diabetes. The primary question it aims to address is:
Can long-term TCM intervention for the treatment of ischemic cerebrovascular disease comorbid with diabetes improve patients' neurological deficits and self-care ability? Participants receiving TCM intervention (universal treatment combined with syndrome-specific treatment) as part of routine cerebrovascular disease management will undergo follow-up assessments at 30 days, 90 days, 6 months, and 12 months within 1 year to evaluate neurological status (e.g., mRS score, NIHSS score) and quality of life indicators.
