Most people understand that the body can be trained. Regular exercise builds strength, endurance, and physical resilience. But what about the brain?
The brain is also trainable — and the field of neuroscience has given us a powerful, evidence-based tool to do it: neurofeedback therapy.
At Neo Clinics in Girona, neurofeedback is one of our most sought-after brain health treatments, helping patients improve focus, reduce anxiety, sleep better, and achieve levels of mental performance that medication and conventional therapy alone rarely deliver. This guide explains exactly what neurofeedback is, how it works, and who benefits most from it.
What Is Neurofeedback?
Neurofeedback — also known as EEG biofeedback — is a non-invasive brain training technique that uses real-time monitoring of the brain’s electrical activity to teach the brain to regulate itself more effectively.
The brain communicates through electrical signals, and these signals produce distinct patterns of activity — called brainwaves — that correspond to different mental states. Delta waves dominate during deep sleep. Theta waves are associated with daydreaming and light relaxation. Alpha waves reflect a calm, focused state. Beta waves characterise active, alert thinking. And gamma waves are linked to peak cognitive performance and insight.
In people with anxiety, ADHD, depression, or sleep disorders, these brainwave patterns are dysregulated — too much activity in some frequencies, too little in others, in ways that directly produce the symptoms the patient experiences.
Neurofeedback works by giving the brain real-time information about its own activity — feedback — and rewarding it when it produces healthier, more balanced patterns. Over a course of sessions, the brain learns to self-regulate, producing the desired patterns consistently without requiring the technology to maintain them. This is neuroplasticity — the brain’s ability to rewire itself — harnessed as a therapeutic tool.
How Does a Neurofeedback Session Work?
A neurofeedback session at Neo Clinics is comfortable, non-invasive, and straightforward:
1. Small sensors are placed on your scalp using a soft cap or gel — no needles, no electrical current
2. The sensors pick up the brain’s electrical activity in real time
3. This activity is fed into specialised neurofeedback software, which translates it into visual or audio feedback — often a game, a film, or a tone
4. When your brain produces the target brainwave patterns (for example, calm alpha waves rather than anxious high-beta), the feedback is positive — the film plays smoothly, the game progresses
5. When your brain drifts back toward dysregulated patterns, the feedback pauses or dims
6. Through this process, your brain gradually learns — without any conscious effort on your part — which states feel rewarding and how to produce them more consistently
The process is entirely unconscious and automatic. You don’t need to “try” to produce the right brainwaves — the feedback system does the teaching. Most patients find sessions genuinely relaxing and often describe them as meditative.
What Conditions Does Neurofeedback Treat?
Neurofeedback has been studied for decades and has a growing evidence base across a range of conditions:
ADHD and Attention Difficulties
Neurofeedback has one of its strongest evidence bases in ADHD. The characteristic brainwave signature of ADHD — excess theta waves and insufficient beta waves in the frontal cortex — is precisely the pattern that neurofeedback targets and corrects.
Multiple systematic reviews and meta-analyses have found that neurofeedback produces significant, lasting improvements in attention, impulse control, and behavioural regulation in children and adults with ADHD. Importantly, these improvements are maintained after treatment ends — unlike medication, which provides benefit only while being taken.
For patients who prefer to avoid stimulant medications, or whose ADHD is incompletely controlled by medication, neurofeedback offers a powerful and durable alternative.
Anxiety and Stress
Anxiety is characterised by excessive high-frequency beta and high-beta brainwave activity — the brain is literally running too hot, too fast. Neurofeedback trains the brain to increase calming alpha activity and reduce hyperactive beta, producing a state of relaxed alertness that becomes the new default.
Patients with generalised anxiety disorder, social anxiety, and panic disorder consistently report meaningful reductions in anxiety symptoms following a course of neurofeedback — often with results that outlast those achieved with medication alone.
Depression and Mood Instability
Depression is associated with reduced left frontal alpha activity and dysregulated activity in the networks involved in emotional regulation. Neurofeedback targeting these patterns can improve mood, motivation, and emotional resilience, and is often used as a complement to other treatments including rTMS therapy.
Sleep Disorders
Sleep quality is profoundly affected by brainwave patterns. Insomnia, non-restorative sleep, and circadian rhythm disorders all reflect underlying dysregulation in the brain’s sleep-wake systems. Neurofeedback protocols targeting increased delta and theta activity and reduced arousal-state beta consistently improve sleep onset, duration, and quality.
Peak Performance — Cognitive and Athletic
Neurofeedback is increasingly used outside clinical populations — by executives, professionals, musicians, and athletes — for cognitive enhancement and peak performance optimisation. Training the brain toward optimal alpha-theta or SMR (sensorimotor rhythm) states has been shown to improve:
- Executive function and decision-making under pressure
- Creative thinking and problem-solving
- Emotional regulation and resilience
- Focus and sustained attention
- Pre-performance anxiety management
- Athletic coordination and reaction time
The use of neurofeedback in elite sport is now well established — research with Olympic archers, golfers, and footballers has demonstrated measurable improvements in performance metrics following neurofeedback training.
Traumatic Brain Injury and Post-Concussion Syndrome
Neurofeedback has shown promising results in patients with TBI and persistent post-concussion symptoms including cognitive difficulties, headaches, mood dysregulation, and sleep disturbance.
Autism Spectrum Disorder
Neurofeedback is used as a complementary therapy for ASD, with evidence supporting improvements in attention, emotional regulation, and social functioning in some individuals.
Is Neurofeedback Safe?
Yes. Neurofeedback is entirely non-invasive — no electrical current enters the brain, no medication is administered, and no surgical procedure is involved. The sensors simply listen to what the brain is already doing.
Side effects are minimal and temporary. Some patients experience mild fatigue or a slightly altered mental state immediately after sessions, particularly in the early stages of treatment, as the brain begins to adjust to new patterns. These effects typically resolve within an hour and diminish as treatment progresses.
Neurofeedback has been used safely in children as young as four years old and in elderly patients.
How Many Sessions Are Needed?
A standard course of neurofeedback consists of 20–40 sessions, typically delivered two to three times per week. Each session lasts approximately 30–45 minutes.
The number of sessions required varies based on the condition, its severity, and the individual’s neuroplastic response. Most patients begin to notice improvements — better sleep, reduced anxiety, improved focus — within the first 8–12 sessions.
At Neo Clinics, we monitor your progress with periodic qEEG assessments throughout your course to track objective changes in your brainwave patterns and adjust the protocol as needed.
Neurofeedback at Neo Clinics, Girona
At Neo Clinics, neurofeedback is always preceded by a qEEG brain scan — a comprehensive map of your brain’s electrical activity at baseline. This allows us to identify precisely which patterns are dysregulated and design a neurofeedback protocol that targets exactly what needs to change in your specific brain.
This diagnostic-first approach is what separates genuinely effective neurofeedback from the generic protocols used by some providers. Your brain is unique, and your training should reflect that.
Neurofeedback is often combined with rTMS therapy at Neo Clinics for a comprehensive, multi-modal brain health programme that addresses both the neurological drivers and the functional consequences of mental health conditions and cognitive challenges.
