Aromatic L-amino acid decarboxylase (AADC) deficiency is a rare, severe, genetic neurological disorder, that normally presents in childhood.1

The rare nature of the disease and symptom overlap with other, more commonly encountered neurological conditions means that it is often misdiagnosed, and patients do not receive the most appropriate support.1

Use the resources on this site to learn more about the signs and symptoms of AADC deficiency, as well as the steps required for diagnosis, to help ensure that patients are given an accurate diagnosis as early as possible.
