Dr Barry Sterman was one of the pioneers of neurofeedback and is known for his groundbreaking work on the functioning of the human brain. 
After completing his doctorate in psychology and neuroscience at the University of California Los Angeles in 1963, Barry Sterman began his research. Among other things, he investigated the effect of a substance made from rocket fuel on cats on behalf of NASA. Almost all the cats suffered epileptic seizures, except those whose brains had previously been trained to produce more SMR rhythms. One of Sterman's co-workers, who also suffered from epilepsy, agreed to the experiment of training her brain with rewarding feedback on the desired EEG activity and was thus able to reduce her seizures. This self-experiment was published in 1972 and is considered the birth of clinical neurofeedback.

With this discovery, Barry Sterman paved the way for neurofeedback in its current form. His discoveries and tireless work have not only expanded our understanding of the brain, but have also enabled numerous applications in medicine.
Barry passed away last December at the age of 87. We remember him and his legacy with the greatest respect and appreciation.

This case study investigates how an intervention with ILF-neurofeedback training (ILF-NFT) can affect the symptoms of an eight-year-old patient with Dravet syndrome (DS), a rare and severely debilitating form of epilepsy.

Background

Dravet syndrome (DS) is a rare and severe form of epilepsy that occurs in one in 40,000 epilepsy patients (Dhamija et al. 2014). Dravet syndrome is caused by the mutation of a gene responsible for the coding of sodium channels in the central nervous system. This genetic mutation is associated with severe neurological impairments in several areas of the brain (Wheless et al. 2020).  Particularly challenging for DS patients are the frequent epileptic seizures, which are largely resistant to treatment. Sleep disorders are also a significant challenge in DS. In addition, DS is characterized by a high degree of heterogeneity in the EEG. According to the international consensus on the diagnosis and treatment of DS, treatment options are limited. (Bureau/ Bernardina 2011). As a result, seizure remission can only rarely be achieved, which is why persistent developmental disorders and sleep problems are likely (Wheless et al. 2020).

Clinically, the core symptoms in particular are treated as part of a DS disorder. However, despite the numerous pharmacological treatment options, there is still no sufficiently effective treatment for DS patients to reduce neurodevelopmental disorders, sleep disorders and epileptic seizures (Moore 2022; Lyons et al. 2020).

Case Study

This case study presents an 8-year-old DS patient who presented with febrile seizures at the age of 5 months with increasing seizure frequency, up to 3 times per week and a seizure duration of up to 30 minutes. In the course of her illness, the epileptic seizures were increasingly triggered not only by fever, but also by low temperatures, physical activity and sensory stimulation. Until the start of ILF neurofeedback therapy, the patient had increasing sleep problems and was awake for two to four hours a night five nights a week.

During a neuropsychological examination in a Danish epilepsy hospital, the girl's mental development was assessed as delayed by around one year. The girl had tried various pharmacological therapies, which had already caused initial damage to her liver function. The use of benzodiazepines also increased the frequency of lethargic moods.

Methods

ILF neurofeedback training was started in December 2019. Since then, the patient has trained almost daily for approx. 30 minutes per session. The NeuroAmp II and Cygnet software are used for this.

Results

The results of the case study consist primarily of the parents' observations, including their records of seizures in the digital app, which they share with the Danish Epilepsy Hospital. After the first three training sessions, there was a clear improvement in sleep, and the waking phases during the night also became significantly shorter. With regard to the epileptic seizures, it was found that they could be reduced both in frequency and intensity. In general, the girl has developed positively since starting ILF-NFT. Her cognitive and motor skills are also developing well, even if they are not age-appropriate.

We are delighted to announce that the Annual Conference for Applied Neurofeedback is back for a second year!

Taking place from 7-8 June in Bucharest, Romania, this networking event promises to be once again a platform for knowledge exchange, collaboration and innovation. Leading international experts, such as Siegfried Othmer and Roxana Sasu, will share their knowledge and present and discuss various topics in the field of Neurofeedback. The conference will offer a wide range of presentations, workshops and panel discussions - suitable for everyone, whether you are an expert in the field or someone curious about the potential of Neurofeedback.

Experts, researchers and enthusiasts will come together to explore the latest advances in this rapidly growing field. In addition, the conference offers ample networking opportunities. Attendees will have the chance to connect with like-minded professionals, exchange ideas and foster collaborations.
