When a baby has a blank stare, it is important to note that it is based on the overall condition. If the baby’s gaze is often dull, to determine the baby’s intelligence, you can do the intelligence scale to rule out congenital mental retardation and other conditions. In addition, there are also cases of thinness and malnutrition, which can be relieved by strengthening nutrition. If the staring is only transient, it is necessary to exclude occasional physical discomfort, such as transient dizziness, epileptic seizures, etc., and to confirm the diagnosis with an electroencephalogram (EEG), ct of the brain, or magnetic resonance imaging (MRI). If the staring is only occasional and the baby is normal in all other aspects such as speech and behavior, it may just be a common phenotype and not a disease state,. It is recommended not to worry too much, pay attention to observation and deal with any problems at any time.
