Can concussion cause non epileptic seizures?
Traumatic brain injury (TBI) is common in psychogenic nonepileptic seizures (PNES). A possible connection is seen in maladaptive symptom modelling. Effects of mild brain injury can include disruption of functional connectivity. This disruption might temporarily fascilitate dissociation and PNES development.
What to do if you have a seizure after a concussion?
