New Study Links Synaptic Dysfunction to Childhood Dementia, Paving Way for Novel Therapies
Researchers from Flinders University have published a study in Nature Communications revealing that synaptic dysfunction is a key factor in childhood dementia, specifically in Sanfilippo syndrome. This rare genetic condition leads to fatal brain damage, with children losing cognitive skills, speech, and mobility after early developmental milestones. The study found that hyperactive synaptic circuits in the brain tissue of affected children contribute to cognitive decline. Using human stem cell-derived cortical neurons, the researchers demonstrated that excitatory synapses become abnormally active, mirroring symptoms seen in children with the condition. The study suggests that synaptic imbalances are not just a byproduct of degeneration but an early driver of the disease.
