Aromatic l-amino acid decarboxylase (AADC) deficiency is a rare genetic disease that affects the nervous system.
How do doctors treat AADC deficiency?
AADC deficiency is very rare, with only about 100 people with the disease described in studies. This means that it is very difficult for doctors to predict whether available treatments will be of help to some patients, all patients, or only a few patients. It is also difficult to predict the effect that medications you may use for other problems will have on this disease.
Medications used for AADC deficiency are aimed at increasing dopamine and serotonin in the brain. These are two important neurotransmitters (cell signaling molecules in the brain) that people with AADC deficiency cannot make enough of.
Medications that block the actions of dopamine or interact with serotonin receptors should be avoided by people with AADC deficiency.
Certain types of anti-emetics, medications intended to help with nausea or vomiting like ondansetron, and granisetron, are also not suitable because they interact with serotonin receptors. Although there is no clinical data as yet, these medications may cause severe side effects in AADC deficiency patients, because these people do not make enough serotonin.
Keeping a record of your child’s medication
It’s important to discuss your child’s medications with your doctor before making any changes. Because AADC deficiency is a rare disease, not all medical professionals may be aware of its symptoms and causes.
It’s also a good idea to specify those medications that your child has not responded to (or has responded poorly to) in these records, in case of an emergency or if your child must be treated by someone other than their primary care physician.
