Neurological aspects of adult phenylketonuriaJ Pietz
Department of Pediatric Neurology, University of Heidelberg, Germany
Curr Opin Neurol 11:679-88. 1998..Magnetic resonance imaging shows white matter abnormalities. However, in single patients, progressive neurological symptoms occurred. Thus, the long-term prognosis of treated phenylketonuria is still under discussion...
Children with developmental language delay at 24 months of age: results of a diagnostic work-upAnke Buschmann

Characterization of white matter alterations in phenylketonuria by magnetic resonance relaxometry and diffusion tensor imagingPeter Vermathen
Department Clinical Research, Unit for MR Spectroscopy and Methodology, University Berne, Bern, Switzerland
Magn Reson Med 58:1145-56. 2007..Intramyelinic edema combined with vacuolization is a likely cause of the WM alterations. Correlations between diffusivity and Phe concentrations confirm vulnerability of WM to high Phe concentrations...
