Symptoms of central nervous development delay mainly include motor dysfunction, sensory dysfunction and cognitive dysfunction.
1. Motor dysfunction: babies with central nervous development delay are lagging behind children of the same age in all aspects of movement, which mainly manifests in the poor development of gross movements such as lifting up, sitting, crawling and standing, and fine movements such as grasping objects with fingers and stacking blocks.
2. Sensory dysfunction: Sensory dysfunction is mainly manifested by unresponsive or slow response to the stimulation of the surrounding environment, visual dysfunction, and poor concentration.
3. Cognitive dysfunction: Cognitive dysfunction usually becomes more obvious after school age. Parents can clearly feel the difference in cognition between their children and children of the same age, which may be due to speech impairment or low numerical ability.
When delayed central nervous development is detected, prompt medical treatment should be sought.
