DETECTION OF METABOLIC DISORDERS AMONG SELECTIVELY SCREENED PEOPLE WITH IDIOPATHIC MENTAL-RETARDATION

Fifth-eight people receiving residential or other services for idiopat hic mental retardation were evaluated for evidence of metabolic diseas e. Five (8%) demonstrated persistent urinary organic acid abnormalitie s on at least three occasions, which pointed towards specific genetic metabolic defects. Instigation of specific treatment programs may have improved the quality of life for one of these participants. Appropria te genetic counseling was provided but could have been instigated much earlier had these investigations been performed as part of a routine workup for idiopathic mental retardation. This pilot study suggests a need for evaluation of other similar populations with idiopathic menta l retardation.
