Three months of midlife exercise lifted mood, not pattern-separation, in the NeuroFit RCT

What the research found
Study (randomized controlled trial). Sahand Farmand and colleagues report in npj Aging (doi 10.1038/s41514-026-00439-w) on 52 previously inactive UK adults aged 45–65 (BMI 20–30). Twenty-seven did three weekly online classes (aerobic, resistance, combined) for 12 weeks versus 25 controls. The primary outcome, mnemonic pattern separation, did not change (β = 0.33, p = 0.26). Depressive symptoms on PHQ-9 fell (β = −1.18, adjusted p = 0.011) even in people without depression, and an in-vitro hippocampal-progenitor assay shifted. Small trial; mood change is not a dementia result. Educational exercise notes, not medical advice.
Evidence level: Clinical trial. This is among the stronger kinds of evidence, but one study rarely settles a question.
