Abstract
Background
In the below case report, we describe the development of psychotic and catatonic symptoms in an individual with Arginine-Glycine-Amindinotransferase (AGAT) deficiency, requiring creatine supplementation.
Basic Procedures and Main Findings
We have conducted a literature review and to our knowledge this is the first documented instance of psychiatric symptoms of this kind developing in an individual with AGAT deficiency.
Principal Conclusions
This case provides clinical support for the role of brain creatine metabolism in the development of psychotic and catatonic symptoms.
