Keywords:
1. Introduction
1.1. The Evolving Landscape of Aesthetic Medicine and Holistic Patient Care
1.2. Psychological Dimensions in Aesthetic Patients: The Pervasiveness of Anxiety and Body Image Concerns
1.3. Neurofeedback as an Emerging Non-Invasive Therapeutic Modality
1.4. Objectives of the Current Literature Review
- Elucidate neurofeedback mechanisms and protocols for anxiety reduction.
- Characterize the psychological landscape of aesthetic patients, focusing on anxiety and body image concerns.
- Assess neurofeedback efficacy in anxiety disorders via recent RCTs and meta-analyses.
- Explore neurofeedback integration as a complementary or alternative therapy in aesthetic care, emphasizing psychological screening.
- Identify literature gaps and propose future research to optimize patient outcomes.
2. Methodology
2.1. Search Strategy and Database Selection
2.2. Inclusion and Exclusion Criteria
- Peer-reviewed original research, systematic reviews, meta-analyses, and RCTs.
- Studies on neurofeedback (EEG-NF, fMRI-NF, or biofeedback) for anxiety disorders (GAD, SAD, PD, PTSD) in adults.
- Articles on psychological factors, anxiety, depression, body image, or BDD in aesthetic patients or cosmetic procedure populations.
- Published from June 2015 to June 2025, in English.
- Non-peer-reviewed articles, editorials, opinion pieces, or conference abstracts.
- Studies primarily on pediatric populations, unless directly relevant to adult mechanisms or neurofeedback principles.
- Studies on other mental health conditions where anxiety was not a primary outcome or significant comorbidity.

2.3. Data Extraction and Synthesis Approach
3. Findings
3.1. Fundamentals of Neurofeedback: Mechanisms, Modalities, and Protocols for Anxiety
3.1.1. Core Principles of Brainwave Regulation and Operant Conditioning
3.1.2. Neurofeedback Modalities and Brainwave Frequencies in Anxiety
- Delta (1–4 Hz): Deep sleep, unconsciousness.
- Theta (4–8 Hz): Creativity, meditation, linked to depression/anxiety.
- Alpha (8–13 Hz): Alert peacefulness, meditation; lower (8–10 Hz) for recall, upper (10–13 Hz) for cognitive performance.
- Sensorimotor Rhythm (SMR, 13–15 Hz): Mental alertness, physical relaxation.
- Beta (15–20 Hz): Thinking, focus; high beta (20–32 Hz) linked to anxiety.
- Gamma (32–100 Hz): Learning, problem-solving.
3.1.3. Neurofeedback Protocols for Anxiety Disorders
| Protocol Type | Target Frequency/Ratio | Brain Region (Common) | Mechanism/Rationale for Anxiety | Key Outcomes/Evidence |
|---|---|---|---|---|
| Alpha Training | Enhance Alpha (8–11 Hz) | Occipital, Parietal, Frontal (O1, O2, C3, F3, F4, P3, P4, Pz) | Promotes calm attentiveness, reduces anxiety | Decreases state/trait anxiety in GAD after 10 sessions, persisting 1 month (Hou et al., 2021). |
| Alpha/Theta (AT) Training | Enhance Theta (4–7 Hz) over Alpha (8–11 Hz) | Pz (Parietal) | Facilitates deep relaxation, stress reduction | Reduces anxiety, beneficial for PTSD (Peniston & Kulkosky, 1991). |
| SMR Training | Enhance SMR (12–15 Hz) | Cz (Central) | Promotes mental alertness, physical relaxation | Greater immediate state anxiety reduction in GAD vs. AT (Daneshvar et al., 2025). |
| Beta Training | Reduce High Beta (20–32 Hz) | Frontal (F3, F4) | Decreases worry, restlessness | Improves attention, reduces hyperactivity in anxiety (Arns et al., 2017). |
