The Traditional ViewThe Traditional View
Medical Education - MD perspective Medical literature, clinical experience
Disorders - signs & symptoms Evaluation - history, PE, Lab Therapy - studies of medical
outcome
![Page 3: Quality of Life & Epilepsy Quality of Life & Epilepsy Orrin Devinsky, M.D.](https://reader033.fdocuments.net/reader033/viewer/2022052317/56649e9e5503460f94b9ffeb/html5/thumbnails/3.jpg)
QOL: QOL: A Different ViewA Different View
QOL - Defined by patient not MD Should patient’s perspective be
filtered through “objective medical lens”? - NO
QOL is about listening, changing perspective, and using the patients’ view as the ultimate measure of outcome
![Page 4: Quality of Life & Epilepsy Quality of Life & Epilepsy Orrin Devinsky, M.D.](https://reader033.fdocuments.net/reader033/viewer/2022052317/56649e9e5503460f94b9ffeb/html5/thumbnails/4.jpg)
QOL: QOL: Relevance to Epilepsy?Relevance to Epilepsy?
QOL issues most relevant to chronic disorders, problems beyond disease symptoms
Epilepsy is the paradigm of such a disorder
Seizures are infrequent,AED effects & psychosocial problems are chronic

Epilepsy & The Epilepsy & The IndividualIndividual
Seizures Premonitory, ictal, postictal effects Frequency, clustering, duration,
intensity Fear, stigma
AEDs Social: Independence, self-esteem,
education, employment, driving

A Case StudyA Case Study
29 y.o. woman monthly CPS, rare GTCs Routine 6 mo. Checkup: complains of some
tiredness, blurred vision, nausea Exam - mild nystagmus, tremor Labs - slightly elevated LFTs
MD’s perspective - doing great Woman’s perspective - doing poorly; not
driving, underemployed, fearful of seizures, troubled by AEs

PGE and Behavior:Absence Epilepsy
(Wirrell et al, 1997)
56 absence epilepsy v. 61 JRA patient Pts with absence epilepsy had more
academic, personal, and behavioral disorders (p<.001)
Those with ongoing seizures had worse outcomes
![Page 8: Quality of Life & Epilepsy Quality of Life & Epilepsy Orrin Devinsky, M.D.](https://reader033.fdocuments.net/reader033/viewer/2022052317/56649e9e5503460f94b9ffeb/html5/thumbnails/8.jpg)
Cognitive & Behavioral Cognitive & Behavioral Changes in Epilepsy: Changes in Epilepsy:
Diagnosis Diagnosis Must diagnose to treat Cognitive-behavioral disorders are
often overlooked - “under appreciated” Not spontaneously reported Not asked about by MD/RN Noted, but considered minor Noted, but considered untreatable
![Page 9: Quality of Life & Epilepsy Quality of Life & Epilepsy Orrin Devinsky, M.D.](https://reader033.fdocuments.net/reader033/viewer/2022052317/56649e9e5503460f94b9ffeb/html5/thumbnails/9.jpg)
Seizure Burden: Seizure Burden: The Great LieThe Great Lie
Are complex partial seizures bad? Memory - long-term consequences Personality changes Affective changes Psychosis
Are tonic-clonic seizures bad? You bet!
![Page 10: Quality of Life & Epilepsy Quality of Life & Epilepsy Orrin Devinsky, M.D.](https://reader033.fdocuments.net/reader033/viewer/2022052317/56649e9e5503460f94b9ffeb/html5/thumbnails/10.jpg)
Epilepsy & Progressive Epilepsy & Progressive Cognitive/Behavioral Cognitive/Behavioral
DeclineDecline Does it occur? If so, how often? Who is at greatest risk? Different Pathogenic Factors
postictal & interictal effects different seizure types extratemporal foci medications
![Page 11: Quality of Life & Epilepsy Quality of Life & Epilepsy Orrin Devinsky, M.D.](https://reader033.fdocuments.net/reader033/viewer/2022052317/56649e9e5503460f94b9ffeb/html5/thumbnails/11.jpg)
Epilepsy: Progressive Epilepsy: Progressive Cognitive DeclineCognitive Decline
Tuberous Sclerosis (Gomez)
Relation of Seizure and MR Of 140 pts with Szs - 89 MR Of 19 pts w/o Szs - none MR Age of seizure onset and MR related:
MR in 72/79 with seizures before age 1y MR in 6/25 with seizures after age 4 y
? Role of CNS pathology vs. Seizures ? Younger brain protected or at risk

Why Measure Quality of Why Measure Quality of LifeLife
An eye-opening study - Croog et al, 1982, NEJM Captopril vs. propranolol Dogma - beta-blockers are safer than
ACE inhibitors Patients on ACE-inhibitors had better
QOL -- less sedation, depression and sexual dysfunction
![Page 13: Quality of Life & Epilepsy Quality of Life & Epilepsy Orrin Devinsky, M.D.](https://reader033.fdocuments.net/reader033/viewer/2022052317/56649e9e5503460f94b9ffeb/html5/thumbnails/13.jpg)
AEDs and QOLAEDs and QOL
AEDs effects on QOL Dose related Idiosyncratic Individual sensitivity Cognitive & Behavioral effects
Hard to measure - executive & social function
“Taking meds”, “Being sick” Balance vs. Seizures effects on QOL
![Page 14: Quality of Life & Epilepsy Quality of Life & Epilepsy Orrin Devinsky, M.D.](https://reader033.fdocuments.net/reader033/viewer/2022052317/56649e9e5503460f94b9ffeb/html5/thumbnails/14.jpg)
QOL and Endocrine QOL and Endocrine IssuesIssues
Endocrine effects on seizure control
Epilepsy-related effects on fertility, pregnancy outcome, parenting
Genetic factors AED effects on libido, endocrine
function, development
![Page 15: Quality of Life & Epilepsy Quality of Life & Epilepsy Orrin Devinsky, M.D.](https://reader033.fdocuments.net/reader033/viewer/2022052317/56649e9e5503460f94b9ffeb/html5/thumbnails/15.jpg)
QOL and QOL and NeuroprotectionNeuroprotection
How do we weigh progressive decline in cognitive and behavioral function?
How do we identify those patients at risk for the Gower’s effect (seizures beget seizures)?
What are the risks of neuroprotection?

QOL & EpilepsyQOL & Epilepsy
Inventories (QOLIEs, Liverpool) now commonly used in research
We need to bring QOL into the office, into our patient’s lives
