Lifestyle changes to prevent memory problems in older adults with depression

Lifestyle Interventions to Prevent cOgnitive Deficits in Subjects With Depressive Symptoms: From mEchanisms to Clinical pRactice

NA · IRCCS Centro San Giovanni di Dio Fatebenefratelli · NCT07009223

This trial will test whether a Mediterranean-style diet, regular supervised exercise, or weekly cognitive training can help prevent memory decline and improve mood in people aged 50–80 with depressive symptoms or major depression but no cognitive impairment.

What this trial studies

This interventional study enrolls adults aged 50–80 with major depressive disorder or depressive symptoms but without signs of cognitive decline and randomizes them to one of three lifestyle interventions: online Mediterranean diet education, supervised regular physical activity, or weekly cognitive training. Participants undergo behavioral programs plus scheduled clinical and cognitive testing, and provide blood and stool samples for inflammatory markers, metabolome analysis, and gut microbiota profiling. Investigators will compare mood and cognitive outcomes across the three groups and link clinical changes to biological measures to explore underlying mechanisms. Some sessions are delivered online while exercise supervision and biological sampling require in-person visits at the coordinating center.

Who should consider this trial

Good fit: Ideal candidates are adults 50–80 years old with a DSM-5 diagnosis of major depressive disorder or measurable depressive symptoms (PHQ-9 or GDS-15 ≥ 5), who can provide informed consent and have no cognitive impairment.

Not a fit: People with diagnosed dementia, existing cognitive impairment, active gastrointestinal, autoimmune, or chronic inflammatory disorders, or recent use of antibiotics or anti-inflammatory drugs are excluded or unlikely to benefit from the interventions.

Why it matters

Potential benefit: If successful, these accessible lifestyle approaches could reduce depressive symptoms, slow or prevent cognitive decline, and improve daily functioning and quality of life.

How similar studies have performed: Prior trials show that exercise, Mediterranean-style diets, and cognitive training can each benefit mood or cognition, but combined mechanistic studies linking these interventions to gut microbiota and inflammation remain relatively uncommon.
