If ADHD is making it hard to stay with a task, manage distractions, or slow down impulsive reactions, it is understandable to look beyond the usual options and ask what else might help. Neurofeedback is one approach you may come across. It is designed to work with patterns of brain activity, but the word “neurofeedback” can describe several different technologies, and the evidence is not the same for all of them.
That distinction matters when you are considering neurofeedback for ADHD. Most ADHD research has studied EEG-based training, where brain activity is measured and you receive real-time feedback while learning to change certain patterns. IASIS Microcurrent Neurofeedback is different: it is passive and uses very low-intensity electrical pulses through scalp sensors. This article explains how these approaches differ, what a session may involve, what current ADHD research actually shows, and the questions worth asking before you decide whether neurofeedback belongs in your care plan.
What Neurofeedback Does During an ADHD Session
Traditional EEG neurofeedback is a form of biofeedback. Sensors placed on the scalp record electrical brain activity, and software turns that information into visual or auditory feedback. You might watch a video, listen to a sound, or interact with a simple display that changes when the measured brain activity moves toward a target pattern.
The goal is repeated practice. Over a series of sessions, the feedback is intended to help you become better at regulating the brain activity being measured. ADHD protocols have commonly focused on frequency-band training, such as theta-beta training, or slow cortical potential training. Researchers have studied these approaches because attention, inhibition, and self-regulation involve networks in the brain that can be measured indirectly through EEG.
This does not mean there is one “ADHD brainwave” that can diagnose the condition or predict how you will respond. ADHD is diagnosed from symptoms, development, history, and functioning across settings. Brainwave findings vary between individuals, so neurofeedback should be considered in the context of a proper ADHD assessment, not used as a diagnostic shortcut.
Not All Neurofeedback Is the Same
Before comparing results or deciding whether a program makes sense, check which technology is actually being used. The term neurofeedback is sometimes applied to approaches that work quite differently from the EEG training used in most ADHD trials.
The two approaches below illustrate why that distinction matters:
IASIS uses a passive microcurrent protocol, so the practical experience is different from conventional EEG training. You are not being asked to learn a brainwave pattern through a screen or sound. This difference is also important when reading claims online: evidence for one form of neurofeedback does not prove that every device or protocol produces the same result.
What the Evidence Shows for ADHD
The evidence for neurofeedback in ADHD is mixed, and the most careful reviews do not support presenting it as a proven stand-alone treatment. A 2025 systematic review and meta-analysis in JAMA Psychiatry examined 38 randomized clinical trials involving 2,472 participants aged 5 to 40. When the researchers focused on outcomes rated by people who were probably unaware of the treatment assignment, they found no meaningful overall improvement in core ADHD symptoms. A small positive effect appeared in trials that used established standard neurofeedback protocols, and a small improvement was found for processing speed, but the overall conclusion remained cautious.
Canadian guidance is similarly restrained. The Canadian ADHD Practice Guidelines state that there is insufficient evidence to recommend neurofeedback as a standard treatment for ADHD. That does not mean every individual will have the same experience. It means the research cannot currently support promises that neurofeedback will reliably reduce ADHD symptoms, replace established care, or work for a predictable percentage of patients.
It is also important to separate the evidence on conventional EEG neurofeedback from the evidence on IASIS. A small published pilot study of IASIS Microcurrent Neurofeedback followed 20 adults receiving the intervention for depression, anxiety, PTSD risk, and quality of life. The study reported improvements in several measures, but it had no control group and did not study ADHD. The authors also called for randomized trials and broader testing. For ADHD specifically, that means the IASIS evidence base is still limited.
A useful way to interpret all of this is to keep the claim proportional to the evidence. Neurofeedback may be explored as a complementary option for some patients, but it should not be sold as a cure or positioned as a substitute for a comprehensive ADHD treatment plan.
What to Expect With IASIS Microcurrent Neurofeedback
If you are considering IASIS, the process should begin with a neurofeedback consultation, not a predetermined package. Your history, current symptoms, previous treatments, medications or therapy, goals, and expectations all matter. A consultation should also cover how neurofeedback may fit with the rest of your care and what would count as a meaningful response.
During an IASIS session, small sensors are placed on the scalp and the system delivers very low-intensity signals according to the protocol. The treatment is passive, so you do not have to play a game, watch a feedback display, or consciously try to change your brainwaves. A typical session lasts about 20 to 30 minutes.
The number of sessions should be individualized. A short session does not mean you can know the outcome after one visit, and an early subjective change is not the same as proof that ADHD symptoms have improved. Agreeing in advance on what you will track makes it easier to decide whether continuing is worthwhile.
Questions to Ask Before You Start
Neurofeedback often involves a series of appointments, so it helps to understand the plan before you begin. Ask questions that clarify exactly what is being offered and how progress will be judged. Useful questions include:
- Which type of neurofeedback or neuromodulation is being used, and how is it different from standard EEG neurofeedback?
- What research applies to this exact protocol for ADHD, instead of evidence about neurofeedback in general?
- What symptoms or day-to-day functions will we track before and during treatment?
- How will this fit with medication, behavioural strategies, psychotherapy, school or workplace accommodations, or other parts of my ADHD care?
- How many sessions are being proposed, and when will we reassess whether the plan is helping?
- What short-term effects or unwanted symptoms should I report, and who will review them?
If you have not had a formal ADHD assessment, start there. Difficulties with concentration, restlessness, sleep, anxiety, depression, substance use, thyroid problems, medication effects, and other conditions can overlap with ADHD symptoms. A qualified clinician can help clarify the diagnosis and discuss established treatment options before you decide where neurofeedback fits.
How to Judge Whether Neurofeedback Is Helping
The most useful measure is not whether a session felt relaxing. It is whether the problems that led you to seek care are changing in daily life. Before your first session, choose a few concrete outcomes that matter to you. You might track how often you abandon tasks, how long you can stay focused on routine work, how often you lose important items, or how much prompting you need to finish a sequence of steps.
For a child or teen, feedback from more than one setting can be especially useful because ADHD symptoms often look different at home and at school. For an adult, a partner, family member, or workplace pattern may provide another perspective. The goal is not to turn everyday life into a research project. It is to have enough information to notice meaningful change instead of relying only on a good or bad day.
Set a review point with the clinician. If there is no meaningful improvement in the outcomes you chose, that is a reason to reassess the plan before adding more sessions. If you do notice improvement, consider whether other changes, such as medication adjustments, sleep, therapy, exercise, or reduced stress, happened at the same time. That gives you a more realistic picture of what may be helping.
How We Can Support Your Next Step
If focus problems are affecting your work, school, routines, or relationships, it can help to look at the wider picture instead of treating neurofeedback as an isolated decision. At our Toronto and Oakville clinics, our care is built around functional and precision medicine, with physician-led consultation and individualized treatment planning. We consider your health history, current symptoms, medications, previous treatments, lifestyle factors, and goals before recommending a plan. If you already have an ADHD diagnosis or are receiving established ADHD care elsewhere, we can discuss how IASIS Microcurrent Neurofeedback may fit alongside that care without positioning it as a replacement.
Neurofeedback is one part of our broader approach. Our services include functional medicine, hormone and thyroid care, IV nutrient therapy, longevity and disease-prevention care, pain management, and regenerative medicine. Those services can be relevant when concerns such as fatigue, brain fog, stress, hormone or thyroid issues, pain, or recovery are part of the overall health picture. The goal is not to assume that another health issue is causing ADHD symptoms. It is to make sure concentration and cognitive concerns are considered in context, especially when more than one factor may be affecting how you feel and function.
At Upper Room Clinic, we can help you review whether IASIS is appropriate for your goals, explain what the protocol involves, and decide what you want to track if you move forward. A useful next step is a consultation where you can bring your questions, current treatment plan, and concerns about focus or cognitive performance. From there, we can recommend a path that stays proportionate to the evidence and coordinated with the rest of your care.
