Each of the following is related to this patient's seizure disorder EXCEPT one. Which is the EXCEPTION?
Patient case: Crown preparation in a patient with epilepsy and autism
Patient: Male, 27 years old
Chief Complaint: Accompanied by his mother, who requests a crown for a fractured upper front tooth.
Background: Autism spectrum disorder and generalised tonic-clonic epilepsy. Last seizure four months ago. Takes levetiracetam. Communicates in short phrases and repeats them; sensitive to bright light and loud sound.
Vital Signs: BP 118/74 mmHg · HR 78 bpm
Findings: Tooth #8 has a large failing composite with a fracture line. Heavy wear on the anterior teeth. Rest of the dentition intact.
Show answer and explanation
Correct answer: A. Repetitive verbal phrases and echolalia
- A. CORRECT as the exception. Repetitive speech and echolalia are features of AUTISM SPECTRUM DISORDER, not of the seizure disorder. They belong to the restricted, repetitive patterns of behaviour that define ASD, and they are present between episodes as a stable communication style. Attributing them to epilepsy conflates the two diagnoses this patient carries.
- B. Orofacial trauma during a seizure is common and clinically important: fractured teeth, tongue and cheek lacerations, and TMJ injury. It is one reason to protect the airway and clear the mouth but never to force anything between the teeth.
- C. Loss of consciousness with tonic then clonic phases is the definition of a generalised tonic-clonic seizure.
- D. Post-ictal confusion, drowsiness and headache follow a generalised seizure and can last from minutes to hours — relevant to whether you can safely discharge a patient after an office episode.
