Patient's question:
The child is 2 years old. Sometimes, when they are crying or startled, they may immediately experience apnea, followed by gasping for breath. The lips may also turn purple. In severe cases, the child may become fully extended, with the head, neck, and arms stretching to the right, unresponsive to calls, and sometimes their eyes may roll back or they may have.Doctor's answer:
Hello, the situation of the child seems quite complex. The child suddenly experiences breath-holding due to crying, which is common in children under 3 years old. In medicine, this is called "breath-holding syndrome." The child's brain nerve tissue has not yet fully developed, and the central nervous system function is extremely unstable. Therefore, when the child cries uncontrollably or is startled, the temporary high excitement of the cerebral cortex can cause the subcortical centers to temporarily lose control, leading to dysfunction of the central nervous system. The child may then immediately stop breathing, appearing as if they are not breathing at all. Subsequently, the lips may turn purple, and in severe cases, the child may become fully extended, with the head, neck, and arms stretching to the right, unresponsive, and sometimes the eyes may roll back or the whole body may convulse.Advice: If this occurs, parents should not panic.
