Enhancing Brain and Mental Health Through Respiratory Training: Clinical Applications in Cancer and Neurodegenerative Disease Care for Patients and Caregivers (Breathing Study)

NCT ID: NCT06788886Sponsor: Mayo ClinicLast updated: 2026-06-10

Summary

This clinical trial studies the effect of respiratory training for enhancing brain and mental health among patients with multiple sclerosis (MS) and cancer (along with their caregivers). The relationship between respiration, cardiovascular effects in the brain, mental health, and neurophysiological mechanisms are significant for patient populations facing complex health challenges, such as those with cancer and neurodegenerative disease, and their caregivers. By measuring oxygen delivery to brain tissues and cerebrospinal fluid flow, this trial may help researchers investigate the potential benefits of respiratory training for patients with MS and cancer and their caregivers.

Detailed description

PRIMARY OBJECTIVE: I. To evaluate the immediate and long-term effects of improved respiratory function on local tissue oxygen delivery and cerebral circulation, by comparing control and training groups. SECONDARY OBJECTIVE: I. To identify key biological aspects of breathing related to brain health and mental well-being, our research explores how respiratory function can improve clinical symptoms related to fatigue and emotional states. EXPLORATORY OBJECTIVE: I. To establish a clinically applicable support tool that uses effective breathing practice to help patients, and their caregivers better navigate their clinical treatment. OUTLINE: Participants are assigned to 1 of 3 studies. STUDY 1: Participants are randomized to 1 of 2 groups. GROUP 1: Participants engage in breathing self-practice routines using a mobile app over 30 minutes daily for 4 months on study. Participants may participate in real-time online breathing sessions with instructors weekly on study. Participants may also participate in in-person breathing sessions with instructors monthly on study. At month 4, participants are randomized to 1 of 2 subgroups. SUBGROUP 1: Participants engage in breathing self-practice routines using a mobile app over 30 minutes daily for an additional 2 months on study. Participants may participate in real-time online breathing sessions with instructors weekly on study. Participants may also participate in in-person breathing sessions with instructors monthly on study. Participants also undergo MRI scans throughout the study. SUBGROUP 2: Participants discontinue breathing self-practice routines for the additional 2 months on study. Participants also undergo MRI scans throughout the study. GROUP 2: Participants engage in walking self-practice routines using a mobile app over 30 minutes daily for 4 months on study. Participants may also participate in in-person group walking session with other participants weekly on study. At month 4, participants are randomized to 1 of 2 subgroups. SUBGROUP 3: Participants engage in walking self-practice routines using a mobile app over 30 minutes daily for an additional 2 months on study. Participants may also participate in in-person group walking session with other participants weekly on study. Participants also undergo MRI scans throughout the study. SUBGROUP 4: Participants engage in walking self-practice routines using a mobile app over 30 minutes daily for an additional 2 months and also engage in breathing self-practice routines using a mobile app over 30 minutes daily for 2 months on study. Participants may also participate in in-person group walking session with other participants weekly on study. Participants may participate in real-time online breathing sessions with instructors weekly on study. Participants may also participate in in-person breathing sessions with instructors monthly on study. Participants also undergo MRI scans throughout the study. STUDY 2: Cancer patients and their caregivers engage in breathing self-practice routines using a mobile app over 30 minutes daily for 4 months on study. Participants may participate in real-time online breathing sessions with instructors weekly on study. Participants may also participate in in-person breathing sessions with instructors monthly on study. Participants also undergo MRI scans throughout the study. STUDY 3: MS patients engage in breathing self-practice routines using a mobile app over 30 minutes daily for 4 months on study. Participants may participate in real-time online breathing sessions with instructors weekly on study. Participants may also participate in in-person breathing sessions with instructors monthly on study. At month 4, participants are randomized to 1 of 2 subgroups. SUBGROUP 5: MS patients engage in breathing self-practice routines using a mobile app over 30 minutes daily for an additional 2 months on study. Participants may participate in real-time online breathing sessions with instructors weekly on study. Participants may also participate in in-person breathing sessions with instructors monthly on study. Patients also undergo MRI scans and blood sample collection throughout the study. SUBGROUP 6: MS patients discontinue breathing self-practice routines for the additional 2 months on study. Patients also undergo MRI scans and blood sample collection throughout the study.

Outcome measures

Primary

Changes in respiratory function correlated with brain activity
Assessed using advanced imaging techniques (such as MRI) and physiological analyses. The approach to data analysis will involve a detailed examination of the MRI data collected from each participant. Respiratory data will be correlated with neuroimaging findings to provide a comprehensive view of how respiratory patterns may influence brain activity.
Time frame: Baseline up to 6 months

Secondary

Change in QOL - PHQ-9
Time frame: Baseline up to 6 months
Change in QOL - GAD-7
Time frame: Baseline up to 6 months
