Neurofeedback is a form of biofeedback that uses real-time electroencephalogram (EEG) monitoring to teach the brain to self-regulate its own electrical activity. By providing immediate feedback about brain wave patterns, neurofeedback gives individuals – and their brains – the information needed to shift toward more regulated, functional states. It is non-invasive, does not involve medication, and has no systemic side effects.

As part of Synchrony Brain Health’s neuroscience-informed care model, neurofeedback is used as a component of integrated treatment for a range of conditions including PTSD, anxiety, ADHD, depression, and sleep disorders. This article explains how neurofeedback works, what the research supports, and what people can expect from the experience.

What Is Neurofeedback?

Neurofeedback (also called EEG biofeedback or neurotherapy) is a research-supported brain training modality that applies the principles of operant conditioning – learning through feedback and reward – to neural activity.

In a neurofeedback session, EEG sensors placed on the scalp detect the brain’s electrical activity in real time. This information is processed by specialized software and fed back to the client – typically as changes in a video, audio, or other media that the client watches or listens to. When the brain produces the desired electrical patterns, the feedback signal continues or intensifies; when it drifts away from the target, the signal pauses or dims. Through hundreds of thousands of such feedback iterations across a course of sessions, the brain learns to produce and sustain more regulated patterns.

The process is fundamentally one of self-regulation training. The brain receives information about its own activity – information it does not normally have conscious access to – and uses that information to learn. The training is gradual and cumulative; sessions build on one another over the course of a treatment protocol.

How Does Neurofeedback Training Work?

The EEG Assessment

Before neurofeedback training begins, an initial EEG assessment establishes a baseline of the individual’s brain wave patterns. In many protocols, this involves a quantitative EEG (qEEG) brain map – a comprehensive recording of brain electrical activity across multiple scalp locations, analyzed to identify regions and frequencies showing dysregulation compared to normative databases.

The qEEG assessment provides a neurological picture that helps guide individualized treatment planning – identifying which brain regions and frequencies are targeted for training.

The Training Session

A typical neurofeedback training session works as follows:

  1. EEG sensors are placed on the scalp at specific locations corresponding to the target training region
  2. The client is seated comfortably and watches a screen (or listens to audio)
  3. The neurofeedback software monitors brain wave activity in real time
  4. When the brain produces the targeted pattern – for example, increased alpha waves in a region showing too much beta – the screen brightens, the audio continues, or another feedback signal is delivered
  5. When the brain drifts away from the target pattern, the feedback signal pauses or changes
  6. Through thousands of such feedback loops in a single session, the brain gradually learns to produce and sustain the desired patterns

This is operant conditioning applied directly to neural activity. The brain learns – through immediate, accurate feedback – to produce states that support more regulated functioning.

Brain Wave Types and Their Significance

Understanding brain wave categories helps clarify what neurofeedback is training:

Wave Type Frequency Associated States
Delta 0.5–4 Hz Deep sleep, restorative processes
Theta 4–8 Hz Drowsiness, creative reverie, trauma-related overactivation when excessive
Alpha 8–12 Hz Calm alertness, relaxed focus, mind-body bridge
Beta 12–30 Hz Active thinking, focused attention, problem-solving
High Beta 20–30+ Hz Anxiety, hyperarousal, rumination when excessive

Different conditions are associated with characteristic dysregulations in these patterns. ADHD, for example, is frequently associated with excess slow-wave activity (theta) in the frontal lobes relative to fast-wave activity (beta) – producing the inattentive, easily distracted presentation characteristic of the condition. Anxiety and PTSD are often associated with excess high-beta activity, reflecting the persistent hyperarousal of the stress response.

Neuroplasticity – The Brain’s Ability to Change

Neurofeedback works because of neuroplasticity – the brain’s inherent capacity to reorganize and adapt based on experience. Every time the brain receives feedback that a particular pattern is “desired,” it strengthens the neural pathways associated with that pattern. Over a course of training, these pathway changes become more consolidated – producing lasting shifts in how the brain regulates itself. Neuroplasticity is not limited to childhood; the adult brain retains significant capacity for functional change throughout the lifespan, which is why neurofeedback can be effective for adults as well as children.

What Conditions Does Neurofeedback Address?

Neurofeedback has been studied across a range of conditions. The strength of the evidence varies by condition, and honest representation of that variation is important.

Strongest evidence base:

  • ADHD – Meta-analyses and multiple randomized controlled trials support neurofeedback as an effective intervention for attention, impulsivity, and hyperactivity. A 2019 meta-analysis by van Doren et al. found significant, lasting improvements in ADHD symptoms with neurofeedback training.

Well-supported by research:

  • PTSD and trauma-related conditions – Studies demonstrate that neurofeedback can reduce hyperarousal, improve sleep, and support emotional regulation in people living with PTSD
  • Anxiety disorders – Research supports neurofeedback’s effects on reducing anxiety symptom severity and physiological markers of arousal
  • Sleep disorders – Neurofeedback protocols targeting specific wave patterns associated with sleep onset and maintenance show promise

Emerging research:

  • Depression – Growing evidence for neurofeedback as an adjunct in treating depressive symptoms
  • Traumatic brain injury (TBI) – Research suggests potential benefits for cognitive and emotional symptoms following TBI

It is important to note that neurofeedback is not FDA-cleared as a standalone treatment for these conditions. Neurofeedback devices are FDA-registered as biofeedback instruments. The research base uses the terms “evidence-based” and “research-supported” – which is accurate – rather than “FDA-approved,” which is not.

What to Expect in Neurofeedback Sessions

Neurofeedback sessions are notably comfortable – many clients describe them as the most relaxing part of their treatment week.

  • Sensor placement: Small, non-invasive EEG sensors are placed on the scalp using conductive gel or cap. There is no electrical current applied to the scalp – sensors only detect, not emit.
  • Session duration: Typically 30 to 60 minutes
  • Session experience: Clients sit comfortably, often watching a video or listening to music that serves as the feedback medium. The feedback occurs automatically through subtle changes in brightness, sound, or visual appearance.
  • Downtime: None. Clients drive themselves to and from sessions and can return to all normal activities immediately.
  • Number of sessions: Most protocols recommend 20 to 40 sessions for optimal results, though some individuals notice changes earlier. The brain learns gradually; consistency and the full course of training are associated with better outcomes.
  • Maintenance: Some individuals pursue periodic maintenance sessions after an initial training course to sustain gains.

Neurofeedback vs. Medication

Neurofeedback and psychiatric medication operate through fundamentally different mechanisms and should be understood as complementary rather than competing approaches.

Psychiatric medications manage symptoms at a neurochemical level – modulating neurotransmitter availability or receptor sensitivity. They work while they are being taken and typically require ongoing use to maintain effects.

Neurofeedback trains the brain at a functional level – building self-regulatory capacity through learning. The goal is for improvements to persist beyond the training period, representing a learned skill of the nervous system.

Many individuals at Synchrony Brain Health use neurofeedback alongside medication as part of a comprehensive treatment plan. Neurofeedback does not replace medication and should never be used to justify stopping prescribed medication without clinical consultation. Medication changes should always be made in partnership with a prescribing clinician.

Is Neurofeedback Evidence-Based?

Yes – with appropriate nuance. Neurofeedback has a substantial and growing research base, and it is appropriately described as an evidence-based approach. At the same time, the field continues to evolve, and the quality of evidence varies across conditions and protocols.

Key research highlights:

  • ADHD: Multiple meta-analyses support efficacy. The van Doren et al. (2019) meta-analysis found significant improvements in attention and hyperactivity/impulsivity, with effects that were maintained at follow-up.
  • PTSD: Studies including work by van der Kolk and colleagues support neurofeedback’s effects on trauma symptoms, particularly when integrated with other trauma-focused approaches.
  • Alpha-theta training: Research supports alpha-theta neurofeedback protocols for anxiety and trauma-related conditions.

The International Society for Neuroregulation and Research (ISNR) maintains evolving guidelines for neurofeedback practice and evidence standards. Synchrony Brain Health’s neurofeedback services align with current clinical standards.

Frequently Asked Questions

How many neurofeedback sessions does it take to see results?

Most individuals begin to notice shifts in how they feel – in sleep quality, emotional regulation, focus, or anxiety levels – after 10 to 20 sessions, though individual responses vary. A full initial training course of 20 to 40 sessions is typically recommended for lasting results. The brain learns gradually; patience and consistency with the full protocol produce the most durable outcomes.

Does neurofeedback work for adults?

Yes. While neurofeedback has been extensively studied in children and adolescents (particularly for ADHD), research supports its effectiveness in adults across a range of conditions. The brain remains neuroplastic throughout the lifespan, meaning adults can learn and benefit from neurofeedback training just as children can.

Is neurofeedback covered by insurance?

Coverage varies by insurer and plan. Some insurers cover neurofeedback for ADHD or other specific conditions when provided by a licensed clinician with appropriate documentation. It is advisable to contact your insurance provider directly to ask about coverage for neurofeedback or EEG biofeedback.

Can neurofeedback be done at home?

Consumer-grade EEG and biofeedback devices exist for home use, but they differ significantly from the clinical-grade systems used in professional neurofeedback practice – in terms of sensor quality, signal accuracy, software sophistication, and the clinical oversight that guides protocol selection. Home devices may offer some benefit as adjuncts, but are not equivalent to clinical neurofeedback and should not be used as substitutes for professional treatment.
