These pathologies, including alternating hemiplegia (AHC) , remain largely unknown and require international scientific mobilization, which is why the symposium was created.
It takes place annually and has become a key moment for:
Presenting research advances 🔬
Sharing new therapeutic approaches 💊
Strengthening international collaborations 🤝
Giving a voice to families and associations involved on a daily basis 👩‍👧‍👦
Why is this event so important?
ATP1A3 diseases mainly affect children and cause severe symptoms: hemiplegic seizures, motor disorders, cognitive difficulties, dystonic episodes…
For families, each scientific advance represents a concrete hope.
The symposium allows for:
to advance the understanding of these complex diseases,
to accelerate research projects ,
to encourage the emergence of new therapeutic approaches ,
to increase the international visibility of these rare diseases.
