The baby’s frequent convulsions in sleep need to be combined with the baby’s age and other accompanying medical conditions for the best comprehensive analysis. 1.If it is a full-term baby or a premature baby, consider neonatal ischemic-hypoxic encephalopathy or hemorrhagic encephalopathy. The neonate’s cerebral cortex is not yet well developed, so the limb activities are mainly controlled by the subcortical center, thus there will be involuntary and purposeless shaking of the limbs. 2, the larger baby sleep twitching suggests the possibility of calcium deficiency. Low blood calcium leads to spasmodic convulsions due to hyperexcitability of nerves and muscles. The child twitches during sleep, if only occasionally, without fever, can exclude the twitching caused by febrile convulsions as well as epileptic twitching. If the child has calcium deficiency and low blood calcium, calcium and vitamin D can be given to the child, which has a significant therapeutic effect on the child’s night terrors, night cries, pillow rubbing, occipital baldness, loss of appetite, indigestion, developmental delay and other symptoms. 3, epilepsy and partial encephalopathy is also one of the causes of pediatric convulsions. If children have repeated convulsions, no fever, and no abnormalities are found in the examination, epilepsy should be considered first. Children are found to have nighttime convulsions combined with symptoms, most of which are pathological, it is best to go to the hospital for examination in a timely manner and not to delay the condition.
