The psychomotor overexcitability is one of Dabrowski's supersensitivities common in gifted children. It is characterized primarily by high levels of energy. Children with this OE (overexcitability) seem to constantly on the move. Even as infants they need less sleep than other children, and as adults, they are able to work long hours without tiring.
Children with this OE also may be misdiagnosed as ADHD. While they can be active, they are quite capable of focused concentration unless they are insufficiently mentally stimulated. The lack of mental stimulation can be a problem for these children in school.
