If your kid is diagnosed with epilepsy, ADHD, or some neurological disorder, probably neurostimulation for kids has been mentioned during the talk with your doctor. It certainly sounds like a complex technology. For many parents, a first reaction is fear. However, this is a real and viable pediatric treatment method these days. Knowing the basics will help you frame relevant questions.
You should know this before the next doctor’s visit.
What Is Neurostimulation?
Neurostimulation aims at altering brain or nervous system functioning through electrical stimuli. It can be considered similar to a pacemaker, only this one is for the brain. Instead of maintaining heartbeat, it balances irregular brain signals.
Two main types can be distinguished:
- Invasive neurostimulation — the patient undergoes an operation to have a device implanted somewhere inside the brain or its vicinity
- Non-invasive neurostimulation — performed from outside of the scalp without surgery, like tDCS means that apply a mild current to the skull externally
The most suitable way will totally be dependent on your kid’s health status, age, and how their brain reacts to other therapies.
Common Types and Their Functions
Vagus Nerve Stimulation (VNS)
VNS is the most popular and well-researched type in children. A tiny gadget implanted under the skin of the chest delivers soft electric signals up the vagus nerve to the brain.
Parents, keep the below in mind:
- Cleared by FDA to be used in kids from 4 years of age
- Majorly given to patients with epilepsy resistant to drugs
- Seizure rate reduction with time is seen by the majority
- Some parents noticed kids’ improved mood as a bonus
Deep Brain Stimulation (DBS)
DBS consists of implanting electrodes deep into the brain, most commonly in the thalamus. It is considered for pediatric patients having very severe epilepsy not responding to medication or suffers from movement disorders such as dystonia.
Points for parents:
- This is a surgery that takes place under general anesthesia
- The implant emits signals periodically, independent of brain activity
- Is viewed as a last resort after trying all other treatments
- Presents all risks involved with any brain operation
Responsive Neurostimulation (RNS)
RNS is an innovative device that adapts its operation. It always examines brain activity and stimulates only on detecting the earliest pre-seizure signals.
Features:
- Compared with DBS, this one is more selective since it will only stimulate when necessary
- More than half of patients enjoy a seizure drop of at least 50%
- Initially created for grown-ups, now introduced in pediatric therapy too
- Parents will need a remote monitor at home for data sharing with team
Transcranial Direct Current Stimulation (tDCS)
Researchers have shown interest in tDCS, a painless method related to brain stimulations that could be effective in ADHD and learning difficulties treatment. It gives a very weak electrical current through the scalp with the help of electrodes outside the skull to slightly change the activity of the brain areas involved.
Different features:
- No surgery or implants are required
- Primarily prescribed in ADHD, problems in learning, and headache
- Investigations have demonstrated shedding of symptoms associated with inattentiveness and impulsivity in kids
- Generally mild side effects, occasional headaches mainly
- Still quite a new field, expert advice is a must
Non-invasive devices like from tDCS Devices make it easier and safer to begin with brain stimulation in families thinking of the alternatives besides medication.
What Conditions Can Neurostimulation Help?
Neurostimulation is no longer limited to epilepsy. Here is where the evidence currently stands:
| Condition | Best-Studied Method | Evidence Level |
|---|---|---|
| Drug-resistant epilepsy | VNS, RNS, DBS | Strong |
| Dystonia | DBS | Strong |
| ADHD | tDCS | Growing |
| Chronic migraine | Non-invasive neuromodulation | Moderate |
| Learning difficulties | tDCS | Early stage |
If your child has tried two or more medications without success, neurostimulation is typically the next conversation to have with a specialist.
What About Safety and the Brain of a Child?
It is the main and only question for parents and it cannot be omitted from the discussion.
Children are not just smaller adults. Their brains mature, hence stimulation of these brains may have different outcomes than in adults. Most devices were made keeping adults in mind and later were adapted for kids, thus challenges exist:
- The electrodes and gadgets must fit a small child’s head correctly
- Children live longer so multiple device replacements might be necessary
- Long-term impact on brain maturation is still unknown
- Children below five need thorough observations and dose adjustments
Safety in case of tDCS is considered in general to be mild in children. Most commonly, headache is the only side effect and this usually goes away quickly.
Risks from VNS, DBS or RNS include the potential complications of surgery in general: infection, bleeding, and issues with the device. However, safety records for VNS usage in pediatric epilepsy are quite impressive given that it has been used for decades.
Shortly speaking, safety data for well-established uses are robust. For novel or off-label uses of younger children, there is a scarcity of studies. That is precisely where a specialist is indispensable.
What To Ask the Doctor
It will really make a difference if you come prepared to the consultation. Here are the crucial questions you should bring:
- Has my child definitely used up all other treatment possibilities?
- Which exact brain area would be affected and what would be the expected result?
- Are there any studies of effects and side-effects in children of my child’s age and condition?
- What are the side effects, how often do they occur, and when do I need to be worried?
- How long will it take for positive effects to become apparent?
- If it fails, what is the next step?
If your child’s device would be implanted, you should refer also to:
- How often will the battery need to be changed and what does the procedure involve
- Does my child have to avoid certain physical activities?
- What kind of data collection is required and at what intervals?
Parents’ Role in Neurostimulation-Related Treatments
It is not like a spectator stands there and watches while neurostimulation treatment happens; it is parents’ role to make their involvement count for the outcome.
- Keep an accurate diary of seizures, mood and behavior changes, etc. between visits
- Communicate with the school, especially teachers, and medical staff, inform them about the device and the protocol
- Become competent in using the remote monitor in case of RNS implanted device as it helps doctors in fine tuning
- Ask for special arrangements of school during the use of the wearable / home-based devices
Changing the Picture rapidly
Use of neurostimulation for children is a dynamic area. Coming from the experiment, it has turned to be a standard part of care in epileptic many pediatric centers. Non-invasive methods are going beyond clinics to homes and thus families dealing with ADHD and migraine have options other than medications.
The first major step would be to find a practitioner team that specializes in pediatric neurostimulation, even more than in general neurology. It is the developing brain that is different from adult brain and hence require specialist attention. Neurostimulation can be a significant change in children’s life if used with right guidance and support.
