FNON – Understanding Networks for Neuromodulation
From my own experience, I’m increasingly convinced that if you understand neurological networks and their interrelationships – and optimize the affected networks – you’ll always be successful!
We see so many amazing cases in practice; I share just a small selection of them on Instagram. If you want to see thousands of amazing cases, follow Petros Kattou – the creator of FNON.
By the way, I have ridiculously few followers for the kind of content I share!

It’s not that I need any more patients—we’re doing well and are booked up for a long time—but many patients who would urgently need it simply don’t know about it because it’s such a new technology that even most doctors have never heard of it.
In the cases that didn’t work, I hadn’t properly understood the underlying disorder.
Yesterday, this really struck me again:
An MS patient reported persistent brain fog and dizziness—despite our treatment.
Upon further, more intensive questioning, it turned out that it was something completely different:
Instead of brain fog, it was a dissociation between “doing” and “inner experience,” which had developed during her last MS relapse.
Thanks to neuromodulation, she could now play the piano in concert with the orchestra again, at least motorically. However, it feels to her as if it’s not her playing, which is extremely distressing for her, and she calls this state then brain fog.
Her reported persistent dizziness, upon closer examination, turns out to be a peculiar disturbance of peripheral vision: the periphery of her visual field blurs, and she describes this as vertigo.
I fell for her “brain fog” and “dizziness” – actually, it was a sloppy history-taking process, but these things happen in a practice with limited appointment time.
That’s why I just treated her executive centers and vertigo areas—and that’s why we had no success:
if you want to classify “playing concerts as a pianist with multiple sclerosis with an orchestra” as “therapeutic failure.” – than you are just as critical as me!
When I gained a better understanding of the actual manifestation of her symptoms yesterday through a re-analysis and more in-depth questioning, and we then treated the associative centers for “self-awareness” and the thalamic center for peripheral vision” (Corp gen. lat) with neuromodulation, her symptoms improved promptly and for the first time.
I had a similar experience with chronic progressive MS
Initially, apart from moderate initial successes, I hadn’t seen any lasting improvements with neuromodulation in this form of MS.
Until Petros, with a new stimulation device (Newronika), made it possible to treat not only the brain but also the spine.
That’s when we finally saw real improvements, and today I realize that chronic progressive MS is no longer a brain disease but a spinal disease.
Because of this, we now have a patient in the office almost every week or even more often who climb out of their wheelchair and take a few tentative steps. It’s become so commonplace that no one in our office even thinks to make a video about it anymore!
Petros, with his brilliant mind, understands the brain and its “networks” in a way that no one else does
Three years ago, he told me on the phone: “Heli, when I look at a patient, the affected networks in the patient’s brain light up immediately. I only see networks in the brain.”
I didn’t understand it at all back then: “Connectome” and “Trajectome” – these are the connections between various brain regions that are functionally intertwined and must work together correctly to provide the corresponding functions.

Disrupted Connectomes Trigger Discomfort
If these aren’t broken—but merely disrupted—the entire connectome no longer functions correctly.
This can be easily visualized as a microphone positioned too close to an amplifier, resulting in loud feedback noise. Nothing is broken, only a functional disturbance in the sense of a “disruption.”
This is how, for example, PTSD works, where the “protective networks” feed back, and like the “microphone feedback,” they transmit constant stress to the brains “Salient Networks” which then again trigger disturbance of motoric centers.
Dystonia and some tremors are also caused by disruptions in various “striato-cerebellar-thalamo-cortical” networks.
Initially, it took me ages to remember this, but now I’m more familiar with these connections, and to that extent, even more “outlandish” illnesses suddenly become treatable!
when you understand this, “permanent illnesses or limitations” suddenly become treatable
Dr. Rayess Balance Problem since Childhood
Last Sunday I was able to see Dr. Adel Rayess – who gave us a training on spinal manipulation in Vienna – and I could eliminate a balance disorder that had been present for 40 years (injured as a child by a stone thrown at his neck).

The next day I helped a child who had been in a wheelchair for seven years with Louis Barr syndrome (ataxia-telangiectasia) to simply stand up and walk.
The video doesn’t yet have parental permission, but I’m sure I’ll get it and then post it on Instagram.
all based on Network understanding: FNON
Simply because, thanks to Petros, I can better understand not only the affected brain areas but also the “Functional Network Architecture and its treatment with neuromodulation” = FNON.
understanding: not yet good – but better. And it gets better with every training session with Petros!
Currently: Petros will be in Vienna for a training session in June and is also accepting international patients.
