Understanding Epilepsy and Absent Seizures

Epilepsy is a neurological disorder affecting over 250,000 Australians. It’s characterised by recurrent seizures due to unusual electrical activity in the brain. There are multiple types of epilepsy, each with unique seizure types and symptoms. Among them, absent seizures, also known as petit mal seizures, are commonly associated with childhood epilepsy but can affect adults as well. Knowing the signs can make a significant difference in early detection and management.

Types of Epilepsy:

  1. Generalized Epilepsy: Seizures affect both brain hemispheres and can include absent, tonic-clonic (grand mal), and myoclonic seizures.

  2. Focal Epilepsy: Seizures originate from one brain area, leading to focal or partial seizures that may be simple or complex.

  3. Unknown Type: When seizure origin is unclear, the epilepsy may be classified as unknown until further diagnostics.

Absent Seizures: What to Look For Absent seizures can be subtle and are often mistaken for daydreaming. These seizures, usually lasting 10–20 seconds, can occur multiple times daily and often go unnoticed. Here are the common signs:

  • Sudden Staring: The person may suddenly stop what they’re doing and stare blankly, unresponsive to the environment.

  • Loss of Awareness: They lose awareness temporarily, typically not remembering the episode.

  • Automatic Movements: Repetitive motions like lip-smacking, blinking, or small hand gestures may accompany the episode.

  • Quick Recovery: Following the seizure, the person resumes activities as if nothing happened, often unaware of the lapse.

Epilepsy Australia and Epilepsy Action Australia offer resources and support for those affected. If you observe these symptoms, consider a medical consultation, as prompt intervention can help manage epilepsy effectively. Educating ourselves about the signs of epilepsy, especially absent seizures, can lead to early diagnosis and support for affected individuals, fostering better understanding and care across our communities.
