Can new technology bring hope to children who have drug-resistant epilepsy?
More than 500,000 children in Canada and the USA have epilepsy. About a third of those children continue to have seizures despite taking anti-seizure medications, also known as pediatric drug resistant epilepsy (DRE). Surgery may be one option for them, but what if there is another option that is less invasive or more effective? What if new technology can bring hope to children who have DRE?

ABOUT SEIZING HOPE Families with children suffering from pediatric drug resistant epilepsy (DRE) face complex realities. In a world guided by the promises of technology, the goal of Seizing Hope is to raise awareness about the options offered by different technologies specifically for the brain in complement or as an alternative to treatment with medication. As the directors and producers of this mini-documentary, we want to empower and improve decision-making by exploring values and priorities through the lens of the families and doctors who care for them. We compiled the stories of four families with children who have pediatric DRE to shed light on their hope, trust, and empowerment journey.
The views and research presented in this documentary represent a multi-year neuroethics project funded by the National Institute of Mental Health of the USA National Institutes of Health, BRAIN Initiative.

Infographic resources for pediatric Drug Resistant Epilepsy
Ask yourself, “would pamphlets or posters be a good means of sharing information for blinded patients?”. Hopefully your response falls somewhere along the spectrum of, “of course not” to “that’s not ideal”. And you’d be right; when creating a resource for a particular group, it’s essential that their needs be considered to ensure the information is shared in a meaningful and functional way. This is true in all domains, be it websites, videos, or printed resources. If the resource is inaccessible to the group you wish to share your research with, then its usefulness is limited to academic discussion and it will not be effective in the real world.
Despite efforts to elucidate guidelines on how to best engage with the public, research shows that many patient education resources aren’t very palatable to the average person. Issues with technical jargon, lack of visual aids, and incomplete information all contribute to the inaccessibility of an educational resource. These issues can be compounded when sharing findings on complex topics such as neurotechnological treatments for pediatric drug resistant epilepsy (DRE). Ultimately, when creating resources from one’s research, the main concern should be that it is readable, understandable, and useful to those who look to access those resources (1).
The reading age for a text is measured by its readability, which is a proxy score on how easily it can be read and processed by the reader. Readability commonly assesses the use of familiar words, density of syllables, and length of sentences to determine its score. The American Medical Association (AMA) suggests that all patient resources be written at or below 7th grade reading level, the average American reading level (2). However, studies on resources curated for ophthalmology, lung cancer, and dementia found that nearly all patient education materials produced exceeded these AMA recommendations, leading to materials that were beyond the general populations ability to interpret (3,4,5). In areas where patient’s may be suffering from cognitive deficits, such as epilepsy, clarity in written resources is paramount. Yet patient education websites for epilepsy surgery show no greater care for readability than other fields, with the majority written at an excessively difficult reading level (6). This pattern of low readability suggests that presently available patient resources are not accessible to the common patient, and may be contributing to lower levels of health literacy.
While readability is an excellent way to assess whether your audience can read your resource, it doesn’t quite capture whether they can comprehend the information it is sharing. The Patient Education Materials Assessment Tool (PEMAT) developed by the Agency for Healthcare Research Quality measures understandability in terms of content, word choice and style, use of numbers, organization, layout and design, and use of visual aids (7). These metrics are useful for determining how well patients can process a resource’s information and identify the key messages. Applying these measures to current resources reveals how short of the mark they fall in communicating information to patients. In a review of diabetes education materials, only 16% met criteria for understandability (8). Neurosurgery resources were similarly rated with a notable lack of summaries, main messaging, and visual aids (9). This finding is corroborated by another study on epilepsy decision-making, which notes more than half of reviewed patient education materials lacked visual aids entirely (6). Taken together, it’s clear that much improvement is needed to promote clearer communication of research findings to patients.
The final piece of the patient resource puzzle is ensuring the information a resource is sharing is useful to the reader.Meaning, can they apply they information they learned to benefit their healthcare journey? The idea of usefulness aligns well with the PEMAT measure of actionability: “consumers of diverse backgrounds and varying levels of health literacy can identify what they can do based on the information presented” (7). In practice, patient education resources fall short once again, with only 1 diabetes resource meeting criteria for actionability, and the majority of neurosurgery resources failing to identify next steps or tools to help patients take action (8,9). Usefulness is also limited by inclusion of all relevant information, and in cases where decision-making is needed it is important for patients to be aware of all relevant risks and benefits to make informed healthcare decisions. Yet, nearly half of reviewed resources for epilepsy surgery neglected to touch on risks and benefits, with some providing biased information in one way or the other (e.g. discussing risks or benefits but not both) (6). It is startling to see that the vast majority of carefully crafted patient resources are not proving to be useful to the patients they serve.
A Neuroethical approach to Patient Education Resources
So, how do we make patient resources that are more engaging for patients? An excellent case study in this area are the infographic resources curated alongside research on decision-making for pediatric drug resistant epilepsy.
The large NIH funded project “Informing Choice for Neurotechnological Innovation in Pediatric Epilepsy Surgery” has several arms of research consisting of clinical trials,media analysis, youth interviews, family interviews, caregiver interviews, and genetic testing interviews (10-15). Though the methods for each arm of research varied, the methodology for creating patient-centered infographics stayed consistent.
In neuroethics, the patient’s rights, privacy, and voice are held in high esteem, and the NIH in particular has stated that engagement with the public in research is key. Bidirectional dialogue is encouraged to ensure that patients can engage with the research, and researchers can stay abreast of public desires, concerns, and health literacy (16). This bidirectional dialogue was employed in the development of the infographics, seeking patient and caregiver input at various stages throughout the process to guarantee the patient voice was incorporated and to ensure the resulting infographics were readable, understandable, and useful.
Infographic development process
A value-guided iterative approach was used for the development of all the infographics. The key findings of the research were extracted and summarized, informative headers and take-home messages were drafted. A word document was created with the information in plain text within a table, to resemble the proposed infographic layout, and was then reviewed by caregivers and research collaborators to ensure accuracy and understandability. Once through this initial process, the infographic was prepared, refined by the researchers, and sent to caregivers for review via a short 15-minute survey. The survey gathered information about clarity of main points, conciseness, engagement, visual appeal, and usefulness.
The survey also gauged respondent’s prior knowledge, willingness to share the infographic, and preferred format to engage with the resource. With feedback in hand, the final version of the infographic was designed and uploaded to the study’s page with a QR code included in the design to allow for further feedback and refinement in the future.
On the sample infographic included to the side you can see the clear title, summary, research design, and action item (highlighted in red).
Readability was ensured through simple language use informed by PEMAT measures and feedback from caregivers. Understandability was ameliorated through the use of clear design, layout, and imagery. Nesting topics underneath key themes to retain a sense of cohesion. Both risks and benefits were addressed to better inform the reader of all relevant information and the take home messages summarize the useful pieces of information the reader can take away to apply in their healthcare journey.
Now that we have a framework for how to create and improve patient education materials, future researchers will be able to follow in our footsteps and create patient resources that are accessible. Such accessibility in the form of readability, understandability, and usefulness are highly important, as many North Americans do not possess high levels of health literacy (17,18). Health literacy comprises all the necessary skills to access, process, and comprehend health information in order to make informed healthcare decisions (19). Researchers have amassed a wealth of data on health, healthcare, and treatment options that have the potential to greatly impact the lives of many suffering with health conditions. In order to unlock that potential, patient voices need to be acknowledged and incorporated when creating resources. In this way we can bridge a crucial gap between bench and bedside, creating a more equitable and accessible healthcare system for all.

This blog post discusses some of the key findings from a poster presentation for the 2021 annual meeting of the American Academy of Neurology (abstract here) and published in the Journal of Child Neurology (2021, paper here).
Neurotechnologies that can change certain functions of the brain may help children with a type of epilepsy that responds poorly to anti-seizure medication (drug-resistant epilepsy). However, there are important differences in the way that parents and doctors make treatment decisions about them.
For parents and caregivers of children with drug-resistant epilepsy (1), treatment choice goes beyond just the direct effect of the treatment on the child’s seizures. They also consider their child in context of the world and their overall quality of life (2). For doctors, treatment choice focuses on the evidence of effectiveness and the seizures themselves (3,4). Understanding both the shared and different decision-making priorities for these groups requires deeper insight into the values that drive them.
The promise and uncertainty of neurotechnologies
Neurotechnologies use innovative techniques to alter brain activity in two main ways: electrical stimulation (i.e., neuromodulation) or the removal of diseased tissue. Modern examples include responsive neurostimulation and laser interstitial thermal therapy. These treatments are gaining in popularity because of their perceived benefits, such as reversibility and limited invasiveness.
Given the special developmental needs of children, we wanted to better understand the trade-offs of benefit and risk. We talked to parents and doctors caring for children with drug-resistant epilepsy across Canada and the USA. We asked them to identify the most important factors they consider when weighing novel neurotechnologies against traditional neurosurgery.
For parents, quality of life is key
When asked about new forms of neurotechnology to treat their child’s epilepsy, parents highlight the benefits including – but also beyond – seizures. Specifically, parents identify quality of life as a crucial factor. This includes life factors such as independence and freedom from the side effects of medication.
“Can they [our child] hold down a job? Can they have a house? Can they get married and have a life? To me, that was important,” said one parent.
Doctors mainly discuss seizure freedom as a measure of success. As one doctor stated, it’s important to consider multiple factors, including quality of life, but that “the big [measure] is seizure control, decreased seizure frequency, and then seizure freedom.”
Not all information is equal
For doctors, scientific evidence is the main factor in considering a new procedure, and to prioritize safety and trust. Introducing novel treatments is therefore challenging (5), because they lack clear evidence while they are being studied, especially in children.
Parents struggle to meet all kinds of information needs. They describe spending hours learning online from a range of sources–from academic articles to blog posts. The credibility and readability of these online resources varies greatly, and they report that reliable sources of information are sometimes difficult to identify.
One parent commented, “[Once the information is] on the internet …we have to decipher whether it’s real.”
Many parents suggest that it would be helpful to receive objective materials directly from hospitals or epilepsy centers.
Preserving trust for novel treatment decisions
Novel treatments disrupt conventional decision-making paradigms. Understanding the different ways medical professionals and parents approach treatment decisions can ease the experience of choosing treatment.
Parents maintain a high degree of trust in their doctors and medical team. Incorporating the different perspectives of families, young patients, and physicians preserves trust and supports inclusive clinical practice.

Dr. Nir Lipsman (Assistant Professor, Division of Neurosurgery, Department of Surgery, University of Toronto) presented “Hacking the mind: How technology is changing the way we view our brain and ourselves” at the 2021 Brain Awareness Week – Annual Distinguished Neuroethics Lecture, held on March 16, 2021.
Overview: As it advances, our relationship with brain technology will change. In this lecture, Dr. Nir Lipsman will discuss how our knowledge of brain circuitry, and how it can go wrong, has informed our understanding of human behaviour. We will then discuss the implications of more sophisticated, precise and less intrusive brain technology, on that relationship, and what it could all mean for the next generation of brain therapy and beyond…
