About Stella Chadwick
Stella Chadwick is the Founder and Clinical Director of Brainstorm Health, a specialist practice supporting children with complex neuroimmune and neurodevelopmental conditions.
This includes autism, PANS, PANDAS, and ADHD, as well as children with behavioural difficulties, learning differences, and other presentations where the underlying biology has not yet been fully explained – with or without a formal diagnosis.
She has been doing this work for more than thirteen years. In that time, Brainstorm Health has supported over 3,500 families.
The work
Stella’s clinical focus is the biology behind why a child’s functioning changes. Immune activation, recurrent infection, gastrointestinal dysfunction, autonomic dysregulation, micronutrient insufficiency – in complex children, these are not separate problems.
They are interconnected, and addressing them properly requires someone who can see the whole picture.
Her approach is grounded in careful, longitudinal assessment.
She looks for patterns across multiple systems, works within a structured clinical framework, and is honest with families about what is realistic and what takes time.
She remains closely involved in the most complex cases and provides clinical oversight across the whole practice, leading a team of nine specialist practitioners who work within her shared clinical methodology. Where cases require it, she works alongside medical professionals including paediatricians and specialist consultants.

Who comes to Brainstorm Health
Most families find their way here because something about their child’s presentation doesn’t fully add up.
Some are watching their child lose ground – slowly, or suddenly, for reasons that have never been properly investigated. Others are still looking for an explanation for difficulties that were present from the very beginning.
Many have already seen multiple clinicians and are still without clear answers – and many do not yet have a diagnosis, or have one that doesn’t fully account for what they are seeing at home.
A label is not a prerequisite. What these children share is not a diagnosis but a complexity – one that sits at the intersection of neurology, immunity, and gut health, and that requires a different kind of clinical thinking to unravel.
That is exactly the kind of complexity this practice was built for.
