What type of encephalopathy presents with lethargy and hypotonia?

Moderate encephalopathy is characterized by symptoms such as lethargy and hypotonia. In this stage of encephalopathy, the infant may appear less alert and exhibit decreased muscle tone. The lethargy suggests a compromised level of consciousness, where the infant is more difficult to arouse than usual, and hypotonia indicates there is reduced muscle strength or resistance to passive movement.

These signs reflect a moderate level of brain dysfunction, which can arise from various underlying issues, including metabolic disturbances or hypoxia. In contrast, mild encephalopathy would typically present with only subtle changes in behavior or tone, while severe encephalopathy might be accompanied by more profound neurological deficits, such as seizures or significant unresponsiveness. Mild hypoglycemia is not classified as encephalopathy and generally presents with symptoms like weakness or irritability rather than the specific findings of lethargy and hypotonia associated with moderate encephalopathy.
