Brain Gray Matter Changes Associated with Mindfulness Meditation in Older Adults: An Exploratory Pilot Study using...

Area of Science:

• Neuroscience
• Cognitive Psychology
• Gerontology

Background:

• Mindfulness-based interventions (MBIs) are known to affect gray matter in healthy adults.
• It is unclear if MBIs induce similar changes in older adults with health complaints.
• This study investigates MBIs' impact on older adults experiencing sleep disturbances.

Purpose of the Study:

• To examine the effect of a standardized MBI on gray matter in older adults with sleep disturbances.
• To explore potential structural brain changes associated with mindfulness meditation in this demographic.

Main Methods:

• An exploratory, single-group, pilot longitudinal study was conducted over six weeks.
• Participants were six older adult volunteers (mean age 66.5) with sleep disturbances.
• Gray matter changes were assessed using voxel-wise analysis pre- and post-intervention.

Main Results:

• A significant increase in gray matter was observed in the precuneus, potentially linked to the default mode network.
• Significant gray matter decreases were also noted, possibly related to MBI-induced improvements in sleep-related brain architecture.

Conclusions:

• Mindfulness meditation practice is associated with detectable alterations in cerebral gray matter in older adults.
• These findings suggest MBIs may influence brain structure in ways relevant to sleep complaints.
