Patients with malnutrition will have symptoms of low function of various systems, which are manifested in the neurological system, such as slow reaction, memory loss, conditioned reflexes not easily established, depression or irritability. After receiving timely nutritional treatment, the growth and development of the brain and the function of the nervous system can be gradually restored, and the subsequent impact on growth and learning is not significant if good eating habits can be maintained.
However, in patients who maintain malnutrition for a long time or are already in severe malnutrition at the time of diagnosis, their mental and behavioral development will be affected, and they need cognitive restoration treatment during hospitalization, and because the brain development may have been affected, even if the malnutrition has been corrected, certain long-term effects are likely to remain.
