What are clinical manifestations in absence seizures?

Staring spells: Clinical features are subtle and may be mistaken for staring or inattention because they only last a few seconds. These include staring into space which could be associated with eye twitching, or twitching around mouth. Often seen in children or young adults. Unlike almost all other types of seizures, children often immediately go back to whatever they were doing. They tend to respond to treatment.
