The causes of sleepwalking in 10-year-old children are mainly divided into physiological and pathological reasons. 1. Physiological reasons: it may be because the brain function of a 10-year-old child is not yet fully developed, if the child is frightened during the day, mental overstress and other reasons caused by the cerebral cortex activity abnormality, then the child sleepwalking may occur. 2. Pathological reasons: Some children may have suffered trauma, infection or epilepsy in the brain, leading to sleepwalking symptoms. Therefore, if a child’s sleepwalking symptoms recur, he or she should go to the hospital for a detailed examination to determine the cause of the illness and take appropriate treatment as prescribed by the doctor.
