What was studied

An analysis of 1,107 participants from the PROTECT cohort using musical questionnaires and averaged cognitive scores.

What it contributes

Some musical activities were associated with selected cognitive measures.

Where the evidence stops

Despite the title’s reference to trajectories, this analysis does not estimate cognitive slopes. Selection and retrospective musical reports limit interpretation; it cannot show that returning to a band preserves cognition.
