Scientists Test New Method That Can Help Diagnose AADC Deficiency

Scientists have discovered a new technique to measure the activity of the aromatic-L-amino acid decarboxylase (AADC) enzyme to help diagnose AADC deficiency. The assay, which uses liquid chromatography-tandem mass spectrometry, was detailed in a study, “Biochemical diagnosis of aromatic-L-amino acid decarboxylase deficiency (AADCD) by assay of…

New Treatments Needed to Improve Quality of Life in AADC

Aromatic l-amino acid decarboxylase (AADC) deficiency has a significant negative effect on patients, their families, and the healthcare system, according to a new review paper that called it “a debilitating disease that significantly impacts quality of life for individuals and caregivers.” The review found that people with AADC deficiency…

Europe Awaits Proposed New Framework for Sharing Health Data

The European Commission is expected to propose a new governing framework for health data next month, called the European Health Data Space (EHDS), with the aim of connecting national health systems to facilitate secure and efficient transfer of data across systems in different European nations. The move is expected to…

Patients With Neurotransmitter Disorders Report Anxiety Troubles

Anxiety and distractibility are among the most common problems reported by people living with AADC deficiency and other disorders that affect neurotransmitter production, according to a new study. Results also highlighted that children with these conditions often view their quality of life more favorably than their parents do. “A…

Report Describes Sisters With Very Mild AADC Deficiency

Two sisters with unusually mild cases of aromatic L-amino acid decarboxylase (AADC) deficiency were described in a recent report. “Our patients may show the most attenuated [mild] type of AADC deficiency. This indicates the importance of ruling out the possibility of AADC deficiency in patients who present with similar…
