A pilot study investigating the association between sleep and cognitive function among adolescents

Area of Science:

• Neuroscience
• Developmental Psychology
• Sleep Medicine

Background:

• Adolescence is a critical period for cognitive development.
• Sleep patterns undergo significant changes during adolescence.
• The interplay between sleep and cognitive function in adolescents requires further investigation.

Purpose of the Study:

• To examine the association between sleep characteristics and cognitive performance in adolescents.
• To explore potential gender-specific differences in cognitive function related to sleep.

Main Methods:

• A sample of 98 adolescents (aged 10-16 years) participated.
• Sleep habits were assessed using a structured questionnaire.
• Cognitive functions, including attention and memory, were evaluated using the Cambridge Neuropsychological Automated Battery (CANTAB), focusing on the attention-switching task (AST) and pattern recognition memory (PRM) task.

Main Results:

• Significant gender differences were observed in attention-switching task (AST) measures (latency, congruent, and incongruent conditions).
• No significant gender differences were found in the pattern recognition memory (PRM) task.
• A significant correlation was found between sleep duration and AST switching cost, and between sleep duration and AST latency.

Conclusions:

• Gender influences cognitive function in adolescents.
• Insufficient sleep is linked to impaired attention and accuracy in adolescents.
• These findings highlight the importance of adequate sleep for optimal cognitive development during adolescence.
