Article Synopsis
- Mindfulness-based stress reduction (MBSR) improves executive functioning and mindfulness traits in adults with autism spectrum disorder (ASD), while both MBSR and social support/education (SE) reduce depression and anxiety levels.
- A study with 78 adults assigned to MBSR or SE showed unique changes in brain connectivity linked to improved mental health outcomes; MBSR specifically decreased connectivity in areas related to anxiety and working memory.
- The results suggest that while both approaches are effective, MBSR offers additional benefits, though more research with larger samples is needed to confirm these findings.
Research studying aging in adults with autism spectrum disorder (ASD) is growing, but longitudinal work is needed. Autistic adults have increased risk of dementia, altered hippocampal volumes and fornix integrity, and verbal memory difficulties compared with neurotypical (NT) adults. This study examined longitudinal aging in middle-age adults with ASD versus a matched NT group, and compared findings with cross-sectional age effects across a broad adult age range.

The participants completed the Behavior Rating Inventory of Executive Function-2 (BRIEF-2) and Adverse Childhood Experiences (ACEs) questionnaires. Seven-minute resting-state fMRI scans were collected.

However, the neural mechanisms of symptom alleviation, and benefit of MBSR beyond education/support groups are unknown. Maladaptive forms of self-reflection are linked to ASD, depression, and anxiety.

There has been increasing interest in the use of neuromodulation techniques aimed at targeting brain regions such as the lateral prefrontal and subcortical regions associated with dysregulation of eating behaviors.
Recent Findings: Invasive brain stimulation techniques have demonstrated promising results in treating severe and enduring anorexia nervosa and morbid obesity.
