Find support (specialists)

Although more and more research supports the efficacy of the ketogenic diet and exogenous ketones; these interventions do not work for everyone. Moreover, the ketogenic diet is not suitable for everyone (see contra-; absolute contraindications). Below you will find mainly Dutch-speaking professionals and some international options. We plan to expand the overview in the future.

Additional Information: Neurological Conditions

The overview above primarily focuses on personal guidance in the field of metabolic psychiatry (e.g., depression, bipolar disorder, ASD, ADHD). However, ketogenic therapy is also applied in various neurological conditions, including epilepsy, migraine, Parkinson’s disease, and dementia. Below are several relevant references; this section will be further expanded in the future.

Epilepsy and Narcolepsy

Ketogenic therapy has been an established treatment for medication-resistant epilepsy for decades. In the Netherlands, the following centers of expertise are active:

SEIN - Stichting Epilepsie Instellingen Nederland: www.sein.nl
SEIN applies ketogenic therapy in epilepsy care and also experimentally investigates the use of ketogenic therapy in narcolepsy.
Erasmus MC - Sophia Children’s Hospital: www.erasmusmc.nl
The ketogenic diet is offered as a treatment option for children with epilepsy through the Department of Pediatrics.

Broader Neurology

To the best of my knowledge, there is currently one center in the Netherlands that specifically focuses on a holistic approach to neurological conditions:

Wardell’s - This team of neurologists has experience with integrative approaches, including lifestyle interventions, for conditions such as migraine and Parkinson’s disease. They are also open to supporting individuals with other neurological conditions. One of the physicians is additionally specialized in rheumatology.

Dementia

Ketogenic therapy in dementia is a widely discussed and actively researched topic in the scientific literature. In the Netherlands, clinical guidance in this area is still limited, and a considerable amount of misinformation circulates.

Dr. Mary T. Newport is an important international source of accessible knowledge. She is a retired physician and author of several books on ketogenic therapy in neurodegenerative diseases. More information can be found at:

Practical Information

Research into ketogenic interventions is promising. For some individuals, the effects can be life-changing. But it doesn't work for everyone, and we currently cannot predict who will benefit and who won’t. There is no one-size-fits-all protocol. Personalization is essential. Still, I’ve included some general information below. I receive questions about “what to do” almost daily, and I as a scientist I am not allowed to give personal advice.
