Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical study is to investigate if lifestyle changes can help prevent cognitive decline and reduce depressive symptoms in people between the ages of 50 and 80 with depressive symptoms or a diagnosis of major depression, but without signs of cognitive decline.

The main questions it aims to answer are:

* Does regular physical activity improve mood and memory in people who are depressed or have depressive symptoms?
* Does cognitive training help prevent mental difficulties in people at risk of cognitive decline?
* Do changes in diet and lifestyle alter the composition of the gut microbiota and immuno-related infiammatory factors?

Researchers will compare three different treatment groups to see which intervention is most effective in improving mental and cognitive health.

The participants:

* Will take part to online sessions on healthy eating based on the Mediterranean diet
* Some will do regular exercise, supervised by a personal trainer
* Others will do weekly cognitive training in small groups at the hospital
* They will provide blood and fecal samples and complete cognitive tests and clinical questionnaires at the beginning, at the end of the treatment (12 weeks), and after 3 months.
