Learning Objectives At the conclusion of this activity, participants will be better able to: • Assess the impact of acute and residual symptoms of cognitive dysfunction in MDD on patient function, quality of life, risk for relapse, and long-term outcomes • Identify patients who might benefit from new pharmacologic treatment options
Cognitive Symptoms in MDD • Among the core symptom domains included in the diagnostic criteria for a major depressive episode1 • >30% of patients who otherwise respond to antidepressant therapy report residual cognitive symptoms (forgetfulness, inattentiveness, mental slowing, apathy, and word-finding difficulty)2 • Prevalence: • Among all adults with MDD: 30% - 40%1 • Among MDD patients >65 years: 50% - 60%2 1. Poletti S, et al. J Affect Disord. 2014;156:144-149. 2. Fava M, et al. J Clin Psychiatry. 2006;67:1754-1759.
Cognitive Symptoms in MDD (cont’d) • May predate onset of MDD episode • Distinct neurobiology • Heritable • Some deficits may improve with antidepressant therapy • Differences in antidepressant effects on cognition • Often persist after treatment • Impact quality of life and functional outcomes Trivedi M, Greer TL. J Affect Disord. 2014;152:19-27.
4 Key Domains of Cognitive Function in MDD The Diagnostic and Statistical Manual of Mental Disorders (5th ed.;DSM–5; American Psychiatric Association [APA], 2013.
Cognitive Symptoms in Measures of Workplace Performance Cognitive Measures Account for More Variability in Workplace Functioning Than Total Depression Severity N=260; HAM-D17 = Hamilton Depression Scale. McIntyre RS, et al. Compr Psychiatry. 2015;56:279-282.
Decline in Gray Matter Volume in Patients with MDD Compared to Healthy Controls • 3-year prospective study comparing 38 patients with 30 healthy controls • Significant decline in gray matter density was noted in the hippocampus, amygdala, ACC, and DMPFC • Threshold was set at P<.001 Frodl TS, et al. Arch Gen Psychiatry. 2008;65:1156-1165.
Association Between Cognitive Function, Disability, and QoL in Patients Treated for Depression Cognitive dysfunction group had significantly greater impairments on the SDS Conclusion: correlation between objectively measured cognitive dysfunction and poorer patient-reported quality of life and disability Kurlander JL, et al. ECNP 2013. Poster P.1.j.006.
Determinants of Cognitive Symptoms in Depression • Patient’s current age/age at onset • Depression severity at onset • Childhood adversity • Level of educational attainment • Frequency/duration of depressive episodes • MDD subtype • Medical/psychiatric comorbidity • Remission status • Treatment McIntyre RS, et al. Compr Psychiatry. 2015;56:279-282.
Measurement of Cognitive Impairment—Clinical Trials • Domains measured/measurement tools utilized vary across trials • Objective testing: neuropsychologic battery • Mini-Mental State Examination, Montreal Cognitive Assessment not sensitive enough for use in MDD • Subjective tests for clinical use • Perceived Deficits Questionnaire (PDQ) • MGH Cognitive and Physical Functioning Questionnaire (CPFQ) • British Columbia Cognitive Complaint Inventory (BC-CCI)
Consistency of Cognitive Impairment in MDD: Meta-analysis • Significant deficits in executive function, memory, and attention • 700 MDD and 700 control subjects (24 studies) • Significant deficits in executive function and attention • 270 unmedicated MDD and 270 controls (8 studies) “Cognitive impairment represents a core feature of depression that cannot be considered an epiphenomenon that is secondary to mood symptoms…” Rock PL, et al. Psychol Med. 2014;44:2029-2040.
Raising the Bar: Evolving Treatment Goals for MDD Cognitive remission 2014 Improved QoL Functional remission ~2010 Improved function Remission ~2000 Response Symptom reduction Before 1990 QoL = quality of life. McIntyre RS. J Clin Psychiatry. 2013;74:14-18.
*Percentages are reported as the remaining percent of those with each symptom at baseline that continued to have the symptom at exit. Response was defined as ≥50% reduction in QIDS-SR16. Presence of symptoms was indicated by a QIDS-SR16 domain score ≥1. McClintock SM, et al. J ClinPsychopharmacol. 2011;31:180-186. What Does Failure to Remit Look Like in Those Who Respond to an Antidepressant?

MDD-Related Cognitive Dysfunction Tends to Be Persistent • Up to to 50% of individuals with MDD have a suboptimal therapeutic response1 • Among individuals deemed responsive to antidepressant therapy (n=267), cognitive problems, lack of energy, and sleeping difficulties were present for nearly half the time during remissions (39% to 44%) and most of the time (85% to 94%) during depressive episodes over 3 years of follow-up2 1. Baune BT, et al. Psychiatry Res. 2010;176:183-189. 2. Nierenberg AA, et al. Psychol Med. 2010;40:41-50.
Traditional Antidepressants: Effects on Cognition • Any improvements in cognition were secondary to improvements in mood symptoms • To date, no conventional antidepressant has shown significant improvements in cognitive symptoms • MDD patients who achieve remission of other symptoms often have persistent cognitive deficits • Some antidepressants worsen cognitive deficits • Study limitations: small sample sizes; lack of replication; not always placebo-controlled; cognitive function not primary endpoint; largest studies conducted in the elderly, or in populations with large age range McIntyre RS, et al.

Investigational Compounds With Potential Procognitive Effect • Modafinil • Considered an effective augmentation strategy for both acute unipolar or bipolar depressive episodes1 • 4-week, open-label study in 35 patients with a history of MDD2 • Partial response of depressive symptoms; some improvement of cognitive function • Donepezil • Available evidence to date does not suggest a clear benefit as adjunctive therapy to antidepressants for cognitive enhancement3 • Clinical trial to assess cognitive improvement for a large sample of cognitively impaired MDD patients with combined treatment of antidepressant/donepezil is ongoing 1.

Targeting Cognitive Deficits in MDD: Cognitive Remediation • Potential aim: to exercise specific pathways with the goal of remediating specific areas of cognitive function • Methods: using behavioral strategies to improve a range of neuropsychologic domains, such as memory and executive functioning • Techniques: cognitive control training sessions, computer games, group discussion, homework, application to real-life situations Bowie CR, et al. J NervMent Dis. 2013;201:680-685.

Measurement-Based Care for MDD • Systematically use measurement tools to monitor progress and guide treatment choices • Regularly scheduled visits • Time-efficient, validated tools • Regularly monitoring symptom improvement, side effects, medication adherence • Use a treatment algorithm with established critical decision points

Summary • Cognitive symptoms of MDD are especially difficult to treat and frequently persist even when patients are otherwise responsive to an antidepressant • Traditional antidepressants frequently failed to adequately address cognition • New multimodal antidepressants appear to be particularly efficacious in targeting the residual symptoms of MDD, particularly in regard to cognitive deficits, with favorable side-effect profiles • However, not all patients may be candidates for these therapies; individualization of therapy is key
Summary (cont’d) • Alternative approaches—especially cognitive therapy—may be helpful • The goal of MDD remains: remission of all symptoms, including cognition • It is critical to continuously monitor therapeutic response and make adjustments accordingly • A number of validated instruments have been developed to facilitate monitoring of response • As with any chronic disease, the patient-provider relationship is paramount for good outcomes
