Tiaobu Xinshen Recipe () Improved Mild Cognitive Impairment of Alzheimer's Disease Patients with Xin (Heart) and Shen (Kidney) Deficiency.

Objective: To observe the intervention effects of Tiaobu Xinshen Recipe (, TXR) on patients with mild cognitive impairment caused by Alzheimer's disease (MCI-AD).

Methods: Totally 88 MCI-AD patients with syndrome of Xin (Heart) and Shen (Kidney) deficiency were assigned to the experimental group (47 cases, treated with TXR) and the control group (41 cases, treated with donepezil hydrochloride) using a random number table. Final recruited qualified patients were 44 cases in the experimental group and 39 cases in the control group. The therapeutic course was 12 weeks. Neuropsychological scales [mini mental state examination (MMSE) and Montreal cognitive assessment (MoCA)], and Chinese medicine (CM) dementia syndromes scales were performed in all patients, and results were compared between groups or intra-group before and after treatment.

Results: MMSE and MoCA scores of the two groups were increased after treatment compared with those before treatment (P<0.05). But there was no statistical difference in MMSE or MOCA scores after treatment between the two groups (P>0.05). CM dementia syndrome score was significantly decreased after treatment in the experimental group compared with the control group (P<0.01). Visual spatial and executive function scores and delayed recall scores of the two groups were increased compared with those before treatment (P<0.01).

Conclusion: TXR could effectively improve cognitive impairment of MCI-AD patients with syndrome of Xin and Shen deficiency.
