Elevated Serum Galectin-1 and Galectin-3 Levels in Children With Specific Learning Disorder: A Case Control Study.

Area of Science:

• Neuroscience
• Developmental Biology
• Immunology

Background:

• Specific learning disorder (SLD) is a neurodevelopmental condition with poorly understood pathogenesis.
• Neuroinflammation, indicated by galectin-1 and galectin-3 levels, is linked to learning and memory processes.
• Investigating neuroinflammatory markers may elucidate SLD etiology.

Purpose of the Study:

• To determine if serum galectin-1 and galectin-3 levels are associated with specific learning disorder (SLD) in children.
• To explore the potential role of neuroinflammation in the development of SLD.

Main Methods:

• A case-control study involving 42 treatment-naive children with SLD and 42 age- and sex-matched controls.
• Psychiatric examinations were used for SLD diagnosis and to exclude attention-deficit hyperactivity disorder (ADHD).
• Serum levels of galectin-1 and galectin-3 were quantified using venous blood samples.

Main Results:

• No significant differences in age, sex, or body mass index (BMI) between SLD and control groups.
• Children with SLD exhibited significantly higher serum galectin-1 levels compared to controls (p=0.019).
• Children with SLD also showed significantly higher serum galectin-3 levels than controls (p=0.003).

Conclusions:

• Elevated serum galectin-1 and galectin-3 in children with SLD suggest a potential role for neuroinflammation in SLD pathogenesis.
• Galectin-1 and galectin-3 may be involved in other learning-related mechanisms contributing to SLD etiology.
• These findings highlight neuroinflammation as a potential factor in specific learning disorders.
