Epilepsy Quiz Answers

  1. B = Facial Angio fibroma

Explanation/Comment: Patient is a suffering from Tuberous Sclerosis, a neuro cutaneous syndrome where epilepsy is the main feature with multisystem involvement.

  • 2.– B = Clobazam

Explanation/Comment: A major problem in the management of seizures is that many of the commonly used anticonvulsants can precipitate or worsen acute attacks.

  • 3.– C = Lamotrigine

Explanation/Comment: The most pronounced decline in serum concentrations is seen for AEDs that are eliminated by glucuronidation (UGT), in particular lamotrigine where the effect may be profound.

  • 4.– D

Explanation/Comment: Epilepsy is considered to be resolved for individuals who had an age-dependent epilepsy syndrome but are now past the applicable age or those who have remained seizure-free for the last 10 years, with no seizure medicines for the last 5 years.

Reference: Robert S. Fisher, Carlos Acevedo, Alexis Arzimanoglou, Alicia Bogacz, Helen Cross, Christian E. Elger, et al. A practical clinical definition of epilepsy. Epilepsia, 55(4):475–482, 2014. http://dx.doi.org/10.1111/epi.12550.

  • 5.– C = Lamotrigine

Explanation/Comment: Gabapentin and Lamotrigine are established level A AED's for elderly.

Epilepsia. 2013 Mar;54(3):551–63. http://dx.doi.org/10.1111/epi.12074. Epub 2013 Jan 25.

  • 6.– C = CJD

Explanation/Comment: EEG shows typical short-interval periodic sharp wave complexes of Creutzfeldt-Jakob disease (CJD).

Ref: Wieser HG, Schindler K, Zumsteg D. EEG in Creutzfeldt-Jakob disease. Clin Neurophysiol. 2006 May;117(5):935–51. Epub 2006 Jan 25.

  • 7.– C Phenytoin

Explanation/Comment: Patients with Stevens–Johnson syndrome and toxic epidermal necrolysis exhibited slower metabolism, or drug clearance; in these patients, there was also a stronger association with the CYP2C.

Ref: Chung WH, Chang WC, Lee YS, et al. Genetic variants associated with phenytoin-related severe cutaneous adverse reactions. JAMA 2014; 312:525–534.

  • 8.– A

Explanation/Comment: Pregnant women on AED should undergo a serum alfa fetoprotein and level II ultrasound at 14–18 weeks of gestation to rule out NTD's.

Reference: Jerome Engel Jr, Timothy A. Pedley, Jean Aicardi. Epilepsy: A Comprehensive Textbook. Lippincott Williams & Wilkins, 2008.

  • 9.– A = Elementary visual hallucinations of occipital seizures are prolonged, slowly developing and last for hours.

Explanation/Comment: Elementary visual hallucinations of occipital seizures are brief for seconds to 3 minutes; develop fast within seconds to 3 minutes. They usually start in the periphery of a hemifield and often march to other seizure symptoms or convulsions. These features may help guide the clinician.

  • 10.– C = OIRDA

Explanation/Comment: Occipital Intermittent rhythmic delta activity. Intermittent rhythmic delta activity is a typical EEG pattern that was originally described by W.A. Cobb in 1945 (J Neurol Neurosurg Psychiatr 1945;8:65–78). OIRDA) is considered good prognostic factor in typical absences.

Reference: Guilhoto LM, Manreza ML, Yacubian EM. Occipital intermittent rhythmic delta activity in absence epilepsy. Arq Neuropsiquiatr. 2006 Jun; 64(2A):193–7. Epub 2006 Jun 9. Occassionally it may be seen in other conditions too.
