Electrocortical Indices of Default Mode Network-Related Activity in ADHD and Modulation Through Mindfulness-Based Cognitive Therapy.

Brain Topography June 26, 2026 Poppy L A Schoenberg, Reza M Zargar, Sevket Hepark

Research suggests that ADHD is characterized by dominant Default-Mode Network (DMN) and diminished Task Positive Network (TPN) activity, which has been linked to detrimentally affecting attention and executive task-dependent functioning. Interventions targeting this DMN-TPN interplay may be clinically important in ameliorating ADHD symptoms. This hypothesis was explored using frequency and...

Mapping neural effects of mindfulness-based cognitive therapy in ADHD using EEG microstates and machine learning models.

Frontiers in Psychiatry 2025 Reza Meynaghizadeh Zargar, Sevket Hepark, Poppy L A Schoenberg

Mindfulness-based cognitive therapy (MBCT) is one of the promising treatments with no known side effects for neuropsychiatric conditions such as Attention-deficit/hyperactivity disorder (ADHD). However, the mechanism of action underlying MBCT is not clearly understood. Here, we applied resting-state EEG microstate analysis and machine learning modeling to characterize brain network dynamics in...

The Feasibility, Effectiveness, and Process of Change of Mindfulness-Based Cognitive Therapy for Adults With ADHD: A Mixed-Method Pilot Study.

Journal of Attention Disorders April 2020 Lotte Janssen, Alicia M De Vries, Sevket Hepark et al.

Objective: Mindfulness-Based Cognitive Therapy (MBCT) is a promising psychosocial intervention for adult ADHD. The feasibility and effectiveness of an adapted MBCT program is explored, together with the possible process of change. Method: Mixed-method study with 31 ADHD patients participating in an adapted MBCT program. Self-report questionnaires on ADHD symptoms, executive functioning,...

Mindfulness-Based Cognitive Therapy Versus Treatment as Usual in Adults with ADHD: a Trial-Based Economic Evaluation

Mindfulness March 23, 2019 L. Janssen, Janneke Grutters, Melanie P. J. Schellekens et al.

ADHD has a considerable economic impact. The aim of this study is to conduct a trial-based economic evaluation of mindfulness-based cognitive therapy (MBCT) added to treatment as usual (TAU) versus TAU in adults with ADHD. A Dutch economic evaluation with a time horizon of 9 months was conducted from the societal perspective in the intention-to-treat (ITT) sample. Costs were assessed with a...

The Efficacy of Adapted MBCT on Core Symptoms and Executive Functioning in Adults With ADHD: A Preliminary Randomized Controlled Trial.

Journal of Attention Disorders February 2019 Sevket Hepark, Lotte Janssen, Alicia M De Vries et al.

The aim of this study was to examine the effectiveness of mindfulness as a treatment for adults diagnosed with ADHD. A 12-week-adapted mindfulness-based cognitive therapy (MBCT) program is compared with a waiting list (WL) group. Adults with ADHD were randomly allocated to MBCT ( n = 55) or waitlist ( n = 48). Outcome measures included investigator-rated ADHD symptoms (primary), self-reported...

Mindfulness-based cognitive therapy v. treatment as usual in adults with ADHD: a multicentre, single-blind, randomised controlled trial.

Psychological Medicine January 2019 Lotte Janssen, Cornelis C. Kan, Pieter J Carpentier et al.

There is a high need for evidence-based psychosocial treatments for adult attention-deficit hyperactivity disorder (ADHD) to offer alongside treatment as usual (TAU). Mindfulness-based cognitive therapy (MBCT) is a promising psychosocial treatment. This trial investigated the efficacy of MBCT + TAU v. TAU in reducing core symptoms in adults with ADHD. A multicentre, single-blind, randomised...

Mindfulness based cognitive therapy versus treatment as usual in adults with attention deficit hyperactivity disorder (ADHD).

BMC Psychiatry September 15, 2015 Lotte Janssen, Cornelis C. Kan, Pieter J Carpentier et al.

Adults with attention deficit hyperactivity disorder (ADHD) often present with a lifelong pattern of core symptoms that is associated with impairments of functioning in daily life. This has a substantial personal and economic impact. In clinical practice there is a high need for additional or alternative interventions for existing treatments, usually consisting of pharmacotherapy and/or...
