Interoception in people with functional seizures.

Takeaway

  • People with functional seizures (FS) are typically less interoceptive than healthy controls, and interoceptive deficits are associated with increased dissociation and seizure frequency.

Why this matters

  • Epilepsy is commonly misdiagnosed; FS which resemble epileptic seizures but are not caused by ictal epileptiform activity may account for up to 20% of epilepsy diagnoses in the USA.

  • Dissociation is an important aspect of FS and it is therefore predicted that interoception – a sensation and perception of the body ‘from within’ – may be impaired in people with FS.
