Verbal dyspraxia in treated galactosemia

Area of Science:

• Metabolic disorders
• Neurodevelopmental disorders
• Pediatric medicine

Background:

• Galactosemia is a rare genetic disorder of carbohydrate metabolism.
• Newborns with galactosemia present with life-threatening symptoms upon milk ingestion.
• Early dietary management improves acute outcomes, but long-term effects are less understood.

Purpose of the Study:

• To investigate the prevalence of specific speech disorders in children treated for galactosemia.
• To explore potential correlations between speech deficits and clinical parameters in galactosemia patients.

Main Methods:

• Speech characteristics of 24 galactosemia patients were assessed.
• Data on age at diagnosis, neonatal symptom severity, and biochemical control were collected.
• Correlation analysis was performed between speech disorders and clinical/cognitive measures.

Main Results:

• Fifty-four percent of patients exhibited verbal dyspraxia, a specific speech disorder.
• The occurrence of verbal dyspraxia was not associated with age at diagnosis, initial illness severity, or metabolic control.
• A potential link was observed between severe verbal dyspraxia and lower IQ scores.

Conclusions:

• Verbal dyspraxia is a significant and common finding in individuals with galactosemia.
• This specific speech disorder appears independently of traditional treatment efficacy metrics.
• The findings highlight an association between a rare metabolic disorder and a distinct neurodevelopmental speech impairment.
