Working Memory Training May Ease Depression
A new meta-analysis in *Translational Psychiatry* finds that working memory training not only improves cognitive performance but also reduces depressive symptoms. This strengthens the case for integrating cognitive exercises with emotional regulation work for neurodivergent students.
The link between working memory and emotional regulation is well-documented, particularly for individuals with ADHD. Both functions compete for resources in the brain's dorsolateral prefrontal cortex, a region critical for executive control. Deficits in working memory can directly impair the ability to process and manage emotional responses effectively. Working memory training is a form of cognitive remediation, a therapeutic approach designed to improve cognitive functions like attention, memory, and problem-solving that are often impaired in depression. The goal of these interventions is to improve daily functioning at school or work, which can in turn help alleviate depressive symptoms. Neuroimaging studies reveal that working memory training can induce structural and functional changes in the brain. The training has been shown to alter brain activation patterns and connectivity within the fronto-parietal network, a key neural system for working memory. In adolescents with ADHD, training has increased activity in frontal and parietal regions, with these changes correlating to clinical improvements. A specific modality, emotional working memory training (eWMT), directly targets the ability to manage emotional information. A meta-analysis covering 16 studies and 883 people found that eWMT significantly reduced both depression and anxiety. The training also enhanced the use of cognitive reappraisal, a key emotional regulation strategy. These findings support established coaching strategies for neurodivergent students that aim to reduce cognitive load. Techniques like breaking large assignments into smaller steps, using checklists, and providing clear, structured routines directly support working memory challenges. Integrating cognitive exercises with other evidence-based supports can create a more robust intervention. Mindfulness activities, visual schedules, and sensory-friendly spaces help students with self-regulation. These tools help manage the cognitive and emotional demands of a learning environment.
