This pilot randomized controlled intervention study compared six months of intensive musical instrument training with psychomotor interventions in people with mild cognitive impairment (MCI), using matched healthy controls as a reference. Global cognition improved modestly, reaching marginal significance only in the music group; both interventions were associated with domain-specific cognitive and sensorimotor gains. Hippocampal gray matter volume remained stable in all groups. Hippocampal functional connectivity declined in healthy controls but remained stable in both intervention groups, a pattern consistent with possible functional neural maintenance.
Key findings
- Global cognitive improvement was modest and reached marginal significance only in the music-training group.
- Both interventions were associated with complementary domain-specific cognitive and sensorimotor gains.
- Hippocampal gray matter volume remained stable across the MCI intervention groups and healthy controls.
- Hippocampal functional connectivity declined in healthy controls but remained stable in both intervention groups.
Why it matters
The findings suggest that structured activities combining cognitive challenge, movement, and engagement may be relevant to cognitive and sensorimotor functioning in early MCI. The differing connectivity patterns also raise the possibility of functional neural maintenance, although the study does not establish that either intervention caused this effect. Larger controlled studies are needed to clarify the magnitude and durability of potential benefits.
What to keep in mind
The study is described as a pilot, and the reported cognitive improvement was modest; the abstract calls for larger controlled trials.
