What type of seizure is characterized by brief lapses in consciousness?

Absence seizures are characterized by brief lapses in consciousness that typically last only a few seconds. During these episodes, the individual may appear to be staring off into space or momentarily disengaged from their surroundings. Often, they are not aware that a seizure has occurred, and they can quickly resume normal activity once it concludes.

These seizures are most commonly seen in children, but they can occur at any age. They differ significantly from other types of seizures. For example, clonic seizures involve rhythmic jerking movements, tonic seizures involve sustained muscle contractions, and grand mal seizures (or generalized tonic-clonic seizures) encompass both tonic and clonic phases, leading to a full-body convulsion. Understanding these distinctions is essential for recognition and management of the various seizure types in clinical practice.
