Plan for Today
• Explain difference between apathy & depression
• Discuss why apathy is such a problem in Parkinson’s disease – the what, why, when & how
• Explain why some treatments for depression actually worsen apathy
• Tips for improving apathy

Apathy vs. Depression
THESIS: Depression = Mood disorder Apathy = Motivational disorder signature of PD progression
Depression Apathy
Motivation – from the Latin “movere”, to move
![Page 8: PD ExpertBriefing Apathy or Depression: Which One Is It?](https://reader030.fdocuments.us/reader030/viewer/2022012708/61a89cf2b835f835fa009cec/html5/thumbnails/8.jpg)
Disorder of motivation
What is Apathy ?
Difficulty initiating activity Low activity levels Less interested in trying out or learning new things Lack of effort or reduced productivity Not completing tasks that were started Lack of interest in socializing Not concerned about issues that used to be important Needing someone to remind or prompt
Examples of apathetic behavior:
![Page 9: PD ExpertBriefing Apathy or Depression: Which One Is It?](https://reader030.fdocuments.us/reader030/viewer/2022012708/61a89cf2b835f835fa009cec/html5/thumbnails/9.jpg)
Cognitive Loss of interest, curiosity
Apathy
Behavioral Reduced initiative; Needs others
to structure activities
Emotion Reduced emotional reactivity,
reward
(Marin, 1991)
(Marin, 1991)
Motivation: To move, activate, energize, from Latin, ‘movere’
Lack of motivation; Failure to initiate goal-directed behavior
Apathy as a Syndrome
![Page 10: PD ExpertBriefing Apathy or Depression: Which One Is It?](https://reader030.fdocuments.us/reader030/viewer/2022012708/61a89cf2b835f835fa009cec/html5/thumbnails/10.jpg)
Apathy: Why is it important?
In many neurologic diseases (AD, stroke, PD), apathy is associated with:
• Reduced daily functioning (ADL’s & IADL’s)
• Increased caregiver stress/distress • Poor illness outcome • Poor treatment compliance • Worse rehabilitation outcome
![Page 11: PD ExpertBriefing Apathy or Depression: Which One Is It?](https://reader030.fdocuments.us/reader030/viewer/2022012708/61a89cf2b835f835fa009cec/html5/thumbnails/11.jpg)
Average Time Spent in Various Activities by People with Parkinson’s with & without Apathy

Apathy Group Not Apathy Group
Beata Ferencz, 2009 Master’s thesis – UF & U. Maastricht
![Page 12: PD ExpertBriefing Apathy or Depression: Which One Is It?](https://reader030.fdocuments.us/reader030/viewer/2022012708/61a89cf2b835f835fa009cec/html5/thumbnails/12.jpg)
Measuring Apathy in PD
MDC Consensus panel, Leentjens et al., 2008), recommend #2 & #6
1. Apathy Evaluation Scale (AES) 2. Apathy Scale (AS) 3. Lille Apathy Rating Scale (LARS) 4. Apathy subscale from FrSBe 5. Item 7 from Brief Neuropsychiatric Inventory 6. Item 4 from UPDRS
![Page 13: PD ExpertBriefing Apathy or Depression: Which One Is It?](https://reader030.fdocuments.us/reader030/viewer/2022012708/61a89cf2b835f835fa009cec/html5/thumbnails/13.jpg)
• 14 item scale, modified from Marin • Are you interested in learning new things? • Does someone have to tell you what to do each day? • Are you indifferent to things?
• 3 Versions: Self-‐report, clinician raBng, family raBng • Reasonable psychometrics
• Criterion validity -‐ novelty toy task • Test-‐retest
Apathy Scale Starkstein et al., 1992
Ferencz, et al., 2012 Most widely used in PD
![Page 14: PD ExpertBriefing Apathy or Depression: Which One Is It?](https://reader030.fdocuments.us/reader030/viewer/2022012708/61a89cf2b835f835fa009cec/html5/thumbnails/14.jpg)
33 item semi-structured interview tapping 9 domains, items are scored yes-not except 1st three items; takes 20 minutes to administer
9 DOMAINS 4 Composite Subscales
Everyday productivity Interests
Taking initiative Novelty seeking
Voluntary actions Emotional responses
Concern Social life
Self-awareness
Intellectual Curiosity Emotion Action Initiation (AI) Self-Awareness (SA)
TOTAL SCORE -36 (normal) to +36 (abnormal)
Lille Apathy Rating Scale (LARS) Sockeel et al., 2006
![Page 15: PD ExpertBriefing Apathy or Depression: Which One Is It?](https://reader030.fdocuments.us/reader030/viewer/2022012708/61a89cf2b835f835fa009cec/html5/thumbnails/15.jpg)
0= normal 1= more passive 2= less initiative/disinterest 3= routine events affected 4= withdrawn, total lack
Easy, but it lacks right mix of sensitivity/specificity Correlates with AS, but has mediocre ROC, miss too many folks at 0 and 1
Bottom Line: Don’t use
N=301 Idiopathic PD
Kirsch-Darrow et al., 2009)
Assessing Apathy using Item 4 from the UPDRS
UPDRS = unified parkinson’s disease rating scale

Our Recommendation
MDC Consensus panel, Leentjens et al., 2008), recommend #2 & #6, also 3
1. Apathy Evaluation Scale (AES) 2. Apathy Scale (AS) 3. Lille Apathy Rating Scale (LARS) 4. Apathy subscale from FrSBe 5. Item 7 from Brief Neuropsychiatric Inventory 6. Item 4 from UPDRS
![Page 17: PD ExpertBriefing Apathy or Depression: Which One Is It?](https://reader030.fdocuments.us/reader030/viewer/2022012708/61a89cf2b835f835fa009cec/html5/thumbnails/17.jpg)
Prevalence-Incidence of Apathy in PD
• Prevalence/incidence depends on how apathy is assessed – estimates range from 12% to 70% across studies
• Tricky, since no formally recognized diagnostic criteria
for apathy
• Recent meta-analysis: almost 40% across 23 studies; apathy associated with lower MMSE, higher UPDRS, older age (den Brok et al. 2015)
![Page 18: PD ExpertBriefing Apathy or Depression: Which One Is It?](https://reader030.fdocuments.us/reader030/viewer/2022012708/61a89cf2b835f835fa009cec/html5/thumbnails/18.jpg)
B. Presence of at least 1 symptom from each of 3 domains must be present for at least 4 weeks
A. Lack of motivation relative to previous level of functioning or societal norms
Proposed Apathy Diagnostic Criteria Starkstein & Leentjens, 2008; adapted from Marin, 1991
1. Diminished goal-directed behavior
2. Diminished goal-directed Cognition
3. Diminished emotion reactivity
e.g., requires others to structure activity, lack of effort
e.g., lack of interest in new experiences, decreased curiosity
e.g., emotional blunting, decreased physiological reactivity
![Page 19: PD ExpertBriefing Apathy or Depression: Which One Is It?](https://reader030.fdocuments.us/reader030/viewer/2022012708/61a89cf2b835f835fa009cec/html5/thumbnails/19.jpg)
D. Symptoms not due to reduced level of consciousness or direct physiological effects of substance (meds, drug abuse, etc.)
C. Symptoms cause clinically significant distress or impairment in social, occupational, & other
areas of functioning
Proposed Diagnostic Criteria continued Starkstein & Leentjens, 2008; adapted from Marin, 1991

Depression in PD
Depressive Disorders Mood Fluctuations
• e.g. major depression,
dysthymia • last from weeks to years • can occur at any stage of
illness
• e.g. shifts from dysphoric to euphoric
• change many times daily • occurs mostly in patients who
have developed motor fluctuations
![Page 21: PD ExpertBriefing Apathy or Depression: Which One Is It?](https://reader030.fdocuments.us/reader030/viewer/2022012708/61a89cf2b835f835fa009cec/html5/thumbnails/21.jpg)
Diagnosing Depression
• Clinical interview • Depression Scales
• Self-Rating (Beck; Geriatric Depression Scale) • Clinician Ratings (Hamilton, MADRS)
• DSM-V criteria • Structured Clinical Interview (SCID)
![Page 22: PD ExpertBriefing Apathy or Depression: Which One Is It?](https://reader030.fdocuments.us/reader030/viewer/2022012708/61a89cf2b835f835fa009cec/html5/thumbnails/22.jpg)
1. Sad mood 2. Diminished Interest/ Pleasure 3. Weight/appetite loss or gain 4. Insomnia or hypersomnia 5. Slowing or agitation 6. Fatigue/decreased energy 7. Feelings of worthlessness/guilt 8. Indecision/poor concentration 9. Recurring thought of death

At least 2 weeks in dura5on, disrup5ve , change
DiagnosBc Criteria for Major Depression
At least 5 of 9 symptoms, including either or both 1 & 2
![Page 23: PD ExpertBriefing Apathy or Depression: Which One Is It?](https://reader030.fdocuments.us/reader030/viewer/2022012708/61a89cf2b835f835fa009cec/html5/thumbnails/23.jpg)
Diagnosis of Depression in PD Can Be Difficult
• Features of PD itself (e.g. bradykinesia, fatigue, insomnia, weight loss, flat affect, concentration problems) can be confused with signs and symptoms of depression
• Syndromic criteria as outlined by DSM may not apply in PD
• Currently available depression rating scales were not designed specifically for use in PD

Why It Is Important to Distinguish Apathy & Depression
Relates to treatment • Use of SSRI’s, common medication for
depression, may actually worsen apathy!!
• Retrospective study at UF, N=181 people with Parkinson’s 42% with apathy, 17% with co-occurring depressive symptoms, only 2% had depression only
• Use of SSRI’s, but not other antidepressants associated with increased apathy
![Page 27: PD ExpertBriefing Apathy or Depression: Which One Is It?](https://reader030.fdocuments.us/reader030/viewer/2022012708/61a89cf2b835f835fa009cec/html5/thumbnails/27.jpg)
Apathy in PD: What We Know
• Distinct from depression • Largely dopaminergic related • Associated with psychophysiological blunting to
emotional pictures (SCR, startle, ERP) • Associated with worsening motor symptoms in medically
managed PD and worsening cognitive status • Associated with older age
![Page 28: PD ExpertBriefing Apathy or Depression: Which One Is It?](https://reader030.fdocuments.us/reader030/viewer/2022012708/61a89cf2b835f835fa009cec/html5/thumbnails/28.jpg)
Neural Systems Underlying Apathy
• Dopaminergic depletion in brain’s motivation circuitry (mesolimbic, D2)
• Mesolimbic • Mesocortical • Nigro-striatal
Evidence: • Worse apathy if taken off dopa meds • Especially dopamine (D2) agonists • Neuroimaging – decreased binding of dopamine in ventral striatum • DBS - reduction of dopa-meds results in increased apathy; tx with dopa agonists improves this

Apathy is an intrinsic part of Parkinson’s disease
• Apathy common in PD, disBnct from depression • Occurs in both demented and non-‐demented PD
• Best cogniBve predictors of apathy in non-‐demented PD are “frontal” tasks such as the Stroop
• Associated with physiologic blunBng to emoBonal pictures • Related to disease severity and age.

• Relatively few randomized clinical trials – these are ‘gold standard’ • Most studies involve increasing some variant of dopamine • Only a few have made “apathy” the main focus; for most, apathy is
secondary
Pharmacologic
1. Dopamine agonists • Pramipexole vs. Ropinirole (Julez et al., 2015)*
• Piribedil (D2-D3) • Rotigotine (aka Neupro®)
2. Methylphenidate 3. Rivastigmine (Exelon® patch)- (Devos et al, 2014)*

Cognitive Training
• Studies in normal aging (ACTIVE TRIAL; VITAL) and mild cognitive impairment; improvements and generalization • Changes in dopamine D1 receptors following working memory training (Klingberg et al., 2009) • Tasks: computer based programs; video games, crossword puzzles, bingo, cards, etc.
• Parkinson’s Disease: Several studies in Parkinson’s disease. Improvement in processing speed; trends for apathy. (Pena et al., 2014)

Bottom Line Apathy is a motivational disorder whereas Depression is a mood disorder Tip: Sadness, guilt, worrisomeness, hopelessness all point to depression. Not apathy. Tip: Decreased initiation, loss of ‘get up and go’ may point to apathy. Apathy worsens with disease progression and is associated with dopaminergic depletion in the brain’s motivational circuits. It has impact on daily activities, treatment outcomes and caregiver distress.

Bottom Line
Treatment approaches are pharmacologic and behavioral • Tip: Make sure patient is on optimal doses of dopa
medications, particularly dopamine agonists (if possible)
• Tip: Avoid SSRI’s if possible • Tip: KEEP MOVING; Use some variant of behavioral
activation and goal setting! • Even if patient cannot do own goal setting, keeping
active (behavioral activation) is critical There is great individual variability – what is not
variable is to keep moving…
