Brief Summary

Ischemic cerebrovascular disease will cause serious harm to the life and safety of patients, and the treatment prognosis is poor. Numerous clinical trials have demonstrated that probiotics can improve cognitive function in people under multimodal. We have previously found that Lactobacillus acidophilus administration could improve cognitive impairment in MCAO and BCAS mice. Therefore, Based on the above research background and the basis of previous studies, we believe that the administration of Lactobacillus acidophilus solid drink (pure Lactobacillus acidophilus strain) can improve the cognitive function of patients with cerebral ischemia through the "brain-gut axis".

Outcome Measures

Primary Outcomes (2)

  • Mini-mental State Examination (MMSE, 0-30) scale

    Higher scale scores mean better cognitive function.

    Three months.

  • Montreal Cognitive Assessment (MoCA, 0-30) scale

    Higher scale scores mean better cognitive function.

    Three months.

Study Arms (2)
