What Researchers Did
Researchers investigated the therapeutic effect of hyperbaric oxygen treatment on cognitive function in patients with Alzheimer's disease (AD) and amnestic mild cognitive impairment (aMCI).
What They Found
One course of hyperbaric oxygen treatment significantly improved cognitive function, as assessed by MMSE and MoCA, in AD patients after 1-month follow-up. This treatment also significantly improved MMSE scores at 3-month follow-up and MoCA scores at 1- and 3-month follow-up in aMCI patients, and ADL scores improved in AD patients after 1- and 3-month follow-up.
What This Means for Canadian Patients
Canadian patients with Alzheimer's disease or amnestic mild cognitive impairment might potentially benefit from hyperbaric oxygen treatment to improve cognitive function and daily living activities. However, this therapy is not yet a standard treatment and requires further validation before widespread clinical adoption.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada, nor did it involve Canadian researchers or participants.
Study Limitations
The study's limitations include a relatively small sample size and the absence of a fully randomized, placebo-controlled design for all comparisons.
