Overview

Full-pressure external counterpulsation (ECP) demonstrated significant cognitive and functional improvements compared to low-pressure treatment in patients with mild cognitive impairment due to Alzheimer disease. The study involved 190 participants over a 12-month period.

Background

Alzheimer disease (AD) is a leading cause of cognitive decline and disability among older adults. Mild cognitive impairment (MCI) due to AD represents an early stage where interventions may be beneficial. External counterpulsation (ECP) has emerged as a non-invasive treatment modality.

Data Highlights

Outcome Measure	Full-Pressure ECP	Low-Pressure Treatment
VADAS-cog Score Improvement	9.95 points	5.22 points
ADAS-cog 14 Score Improvement	6.16 points	2.74 points
Activities of Daily Living Score Change	+2.57 points	-0.49 points
Mini-Mental State Examination Improvement	1.68 points	0.19 points

Key Findings

Full-pressure ECP resulted in a 9.95-point improvement in VADAS-cog scores compared to 5.22 points in the low-pressure group.
At 12 months, the full-pressure group showed a 9-point improvement from baseline, while the low-pressure group showed a 3-point decline.
Activities of daily living scores improved by 2.57 points in the full-pressure group, contrasting with a decline of 0.49 points in the low-pressure group.
63% of patients in the full-pressure group had improved or stable scores on both VADAS-cog and ADCS-ADL scales.
No serious device-related adverse events were reported, with mild skin irritation being the most common issue.

Clinical Implications

The findings suggest that full-pressure ECP may be a viable treatment option for improving cognitive function and daily living activities in patients with early Alzheimer disease. Clinicians should consider the potential benefits of ECP in managing mild cognitive impairment due to Alzheimer disease.

Conclusion

Full-pressure external counterpulsation shows promise as a treatment for cognitive and functional decline in early Alzheimer disease, warranting further investigation into its long-term efficacy and safety.
