Botulinum toxin in Neurology
Dr Marie-Helene Marion’s visionary impact of Neurotoxin on Dystonia Treatment.

Sharing clinical skills
Dr Marie-Helene Marion pioneered the treatment with botulinum toxin injection for dystonia, in 1986, in France, and founded the London BTX centre in 2007.
This centre has been dedicated to the treatment of different focal dystonias (blepharospasm, oro-mandibular and tongue dystonia, cervical dystonia, Meige syndrome, writer’s cramp), and also the use of toxin in facial palsy, hemifacial spasm and hyperhidrosis.
Her long clinical experience, learnt from treating complex dystonic patients, in particular working in a Neuro-ENT clinic at St George’s hospital, London, has taught her the importance of a detailed clinical analysis of the abnormal movement, in order to devise the protocol of injections for individual patients. She has been promoting best practice in botulinum toxin treatment in neurology, and founded the British Neurotoxin Network, 12 years ago.
She stopped seeing patients in October 2023, but she enjoys speaking at conferences, sharing her clinical research, and teaching young injectors at workshops. She is also educating patients with her blog (www.infodystonia.com,with 1000 visitors a month).
Dr Marion has continued to publish, please find the up to date Dr Marion’s publications.

My name is Marie-Helene Marion
I am a French neurologist working in London as a Botulinum Toxin Specialist. I am also specialised in the treatment of movement disorders, including Parkinson’s disease and dystonia.
I am aware that most of my patients have rare disorders, for which the diagnosis is not made or have been delayed for many years. I hope that the information available on this website and on my blog will contribute to an increase awareness, and therefore an early diagnosis and treatment for these conditions. But of course reading information on internet will never replace the benefit of a consultation, where questions are answered in details, following a long interview and a clinical examination.
My interest in movement disorders started in 1981 when I first came to London to study under the late Prof David Marsden. Since that time, I have been working in the field of Parkinson’s disease, being involved in developing continuous infusion techniques and focal dystonia, being the pioneer in France in 1986 for using Botulinum toxin in the treatment of focal dystonia. My experience over the years in these fields has taught me that despite the complexity and the therapeutic challenges, there is always place for hope and that a small improvement can have a big impact on the quality of life of the patient.
