Practical management of behavioral problems in mucopolysaccharidoses disorders

Area of Science:

• Biochemistry
• Genetics
• Neurology

Background:

• Mucopolysaccharidosis (MPS) disorders stem from lysosomal enzyme deficiencies, leading to cellular glycosaminoglycan (GAG) accumulation.
• Excessive GAG storage causes diverse somatic and neurological symptoms, including behavioral and sleep disturbances.
• These neurological issues are primary symptoms in MPS I, II, III, and VII, significantly impacting patients and families.

Purpose of the Study:

• To review current understanding of behavioral and sleep problems in MPS disorders.
• To outline optimal management strategies for these neurological manifestations.
• To consolidate expert insights from an international panel on MPS treatment.

Main Methods:

• Literature review of MPS-related behavioral and sleep issues.
• Synthesis of expert opinions from a dedicated international meeting.
• Focus on management approaches for neurological symptoms in MPS.

Main Results:

• Behavioral problems (hyperactivity, attention deficits, frustration) and sleep disturbances are common primary neurological symptoms in MPS.
• GAG accumulation in neurons is the underlying cause of these neurological manifestations.
• Effective management is crucial due to the significant burden these symptoms place on families.

Conclusions:

• Behavioral and sleep problems are significant neurological manifestations of MPS disorders.
• Expert consensus highlights the need for tailored management strategies.
• Addressing these symptoms is vital for improving the quality of life for MPS patients and their families.
