My name is Marie-Hélène Marion and I am a consultant neurologist, specialis
ed in Parkinson’s disease and in the use of Botulinum toxin (also called Botox) in Neurology.

My training

I studied medicine at the University of Clermont-Ferrand in the heart of the beautiful volcanic region of Auvergne. Then went to Paris to study Neurology as an “ Interne des Hopitaux de Paris” in the most prestigious departments of that time and in parallel studied Neuro-pharmacology (how the drugs work in the brain)

Then I started to have itchy feet and went to London to specialize in movement disorder as a research fellow under Professor David Marsden for 2 years. His passion for Parkinson’s disease, Dystonia and the all field of involuntary movement was contagious and never left me since.

I went back to Paris in September 1986 to work as a Chef de Clinique and pioneer in France the use of Botulinum toxin in Neurology

Then in 1998 I crossed again the channel to follow my Australian husband and worked for 12 years at St George’s hospital, in London, running Movement disorders clinics and various Botulinum toxin clinics. At St George’s I still run a clinic specialized in excessive sweating, in particular facial sweating and hands sweating, and a clinic for voice disorders and severe bent neck.

My private Practice

I stopped my clinical activity on the 1 st October 2023 , being replaced by Dr Fahd Baig and Dr Laure Tourame.    

I have founded the London BTX centre, which is dedicated to the Botox treatment of focal dystonia, (Blepharospasm, Cervical dystonia, Jaw dystonia, Writer’s cramp, Musician’s cramp), Hemifacial spasm, Facial palsy, Tremor, Bruxism and excessive sweating.A special mention for patients with voice disorders who are seen in a joint clinic, unique in London, with an ENT-voice specialist (Ms Lucy Hicklin) and a neurologist (MH Marion).

Movements disorders clinics are also set up for parkinsonian patients and related disorders, with the possibility of offering full assesment of the condition and therapeutic advices customised to the age of the patient, the stage of the disease and the type of complications.

Academic interests

In parallel, I pursue academic projects in the movement disorders field and published this year on Parkinson’s disease and also on complex cervical dystonia with my junior colleagues at St George’s Hospital. I recently organized the British Neurotoxin Network (BNN)  which gathered all the clinicians over UK who are running Botox services for neurological conditions.

I am a regular invited speaker in international meetings on the field of movement disorders and organised workshops on the use of Botox treatment in neurology, as European expert in the field.
