Question

What causes neonatal limb tremors?

Answer

Neonates’ brain nervous systems are still in the developmental stage, which may result in an immature cerebral cortex and a higher excitability of central nervous system cells. This limb tremor phenomenon usually diminishes over time. However, if the tremors persist and are severe, it is advisable to seek professional medical examination by a doctor to determine the specific cause and receive appropriate treatment. Additionally, if the neonate also exhibits symptoms such as diarrhea and vomiting, there may be electrolyte imbalances such as potassium, calcium, and magnesium deficiencies, which can also lead to slight limb tremors. In such cases, a blood electrolyte test should be conducted for diagnosis, and appropriate electrolytes should be supplemented based on the test results.
