Summary
Toddlers with language delays show altered sleep brainwave patterns and sleep spindle development. These neurophysiological differences in early childhood may help identify atypical neurodevelopmental trajectories.
Area of Science:
- Neuroscience
- Developmental Psychology
- Sleep Medicine
Background:
- Sleep is vital for early language acquisition.
- Sleep disturbances are prevalent in children with neurodevelopmental disorders.
- Analyzing sleep microarchitecture in toddlers can reveal neurophysiological markers for early detection of developmental delays.
Conclusions:
- Atypical sleep EEG connectivity and sleep spindle development are detectable in toddlers aged 12-36 months.
- These findings provide insights into the neurophysiological underpinnings of neurodevelopmental disorders.
- Early identification of sleep abnormalities may aid in understanding and intervening in atypical neurodevelopmental trajectories.
