Brain aging is associated with molecular, cellular and structural changes that are robust on the group-level, yet show substantial inter-individual variability. Here we show that deviations in gene expression from normal age-dependent trajectories predict risk for major mental illnesses and neurodegenerative disorders. These results suggest that older molecular brain aging is a common feature of severe mental illnesses and neurodegeneration.
