Affective DisordersAffective Disorders
Depression has a prevalence ranging from 5% to 20%
Current drug treatments are costly, only partly effective and present side-effects limit their therapeutic potential

ExerciseExercise
Exercise increases BDNF in the hippocampus BDNF influences serotonergic system Serotonergic system is intimately linked to depression 5-HT1A receptors are reduced in depressed patients
