Intellectual disability: A potentially treatable condition.

Area of Science:

• Neuroscience
• Genetics
• Developmental Biology

Background:

• Genomic applications have improved the diagnosis of monogenic causes of intellectual disability (ID).
• Understanding neuronal processes underlying cognitive impairment is advancing.
• Rare disease communities are forming to seek targeted treatments for children.
• Current ID treatments primarily address metabolic disorders, showing improved outcomes.

Purpose of the Study:

• To explore potential treatment strategies for a wider range of genetic intellectual disabilities.
• To discuss how novel therapies could alter neurodevelopmental trajectories.
• To position intellectual disability as a treatable condition amenable to precision medicine.

Main Methods:

• Review of current and emerging therapeutic strategies for intellectual disability.
• Discussion of substrate modification, enzyme replacement therapy, gene therapy, and molecular therapies.
• Analysis of the potential impact of these strategies on neurodevelopmental outcomes.

Main Results:

• Genomic advancements facilitate specific diagnoses of intellectual disability.
• Emerging therapies offer potential to modify neurodevelopmental outcomes beyond metabolic disorders.
• Intellectual disability is increasingly viewed as a treatable condition.

Conclusions:

• Intellectual disability, particularly genetic forms, may become treatable through advanced therapeutic approaches.
• Precision medicine offers a promising framework for developing targeted intellectual disability treatments.
• A shift in perspective is needed to consider intellectual disability a condition manageable with targeted interventions.
