Does Diet & Exercise Affect Brain Ageing?

According to de Lucia and colleagues (2020), yes they do.

People with certain variants of genes that play a key role in brain ageing seem to respond better to a healthy lifestyle.

Some versions of the SIRT1 gene are affected by amount of exercise and some variants of the GRB10 gene by whether people eat a Mediterranean
diet.
