Her husband suffered an MI while the extended family was on a cruise celebrating their 40th wedding anniversary. The auditory hallucinations occur at night. Ruth feels guilty, because as a RN, she believes she should have “seen this coming.” She reports being “down,” poor appetite and has lost 4 pounds over 45 days, difficulty concentrating resulting in errors at work, insomnia, and fatigue. Bereavement leads to adverse mental and physical outcomes Associated increased mortality in the surviving conjugal partner when compared to married persons of the same age Highest relative risk of mortality occurred 7 – 12 months after spousal loss Also associated with anxiety, substance use, suicide Symptoms seen: Marked functional impairment Morbid preoccupation with worthlessness Psychotic symptoms Psychomotor retardation Psychosis Rosenzweig AS, Pasternak R, et al.

Investigate if hallucinations Never assume patient is compliant with therapy In fellowship, taught to use an objective depression scale (there are quite a few Center for Epidemiologic Studies-Depression Scale) is quantitative so can trend it Review PHQ-9, GDS, Cornell Have high degree of sensitivity and specificity USPSTF states sufficiency in “asking 2 simple questions: 1. Over the past 2 weeks, have you felt down, depressed, or hopeless? 2. Over the past 2 weeks, have you felt little interst in doing things?” Recommends screening adults for depression when staff-assisted depression care supports are in place to assure accurate diagnosis, treatment, and followup (Grade B recommendation) There may be considerations supporting screening for depression in an individual patient (Grade C recommendation) Positive screen should trigger full diagnostic interview and examination Cornell Scale for Depression in Dementia – caretaker or family member rates severity of symptoms: mood-related signs Behavioral disturbances Physical signs Cyclic functions Ideational disturbances Geriatric Depression Scale – patient answers subjective questions and validated in many studies Looks at attitudes and cognition Less focus on vegetative symptoms Depression is a prodrome Again: depression is linked to cognitive impairment, especially if first episode of depression ever Depression leads to disturbance in executive function; can have “pseudodementia” Use MMSE or Montreal Cognitive assessment (MOCA) Take a Medical History Medication side-effects Drug or alcohol abuse Infection Endocrinopathy (e.g. hypothyroidism) Malignancy Nutritional disorders Sleep disorders (don’t miss sleep apnea) Acyclovir ACE-I B Blocker CCB Corticosteroids Digoxin H2-receptor blockers Interferon alpha L-dopa Methyldopa and clonidine Patten SB, Love EJ.

Dew et al. J Affect Disord 2001;65:155-166 Psychotherapy is under-prescribed (avoid in the demented because of lack of efficacy) Effective for non-psychotic MDD and in dysthymia Several approaches are evidence-based Cognitive Behavior Therapy (CBT) Problem Solving Therapy (PST) Interpersonal Therapy (IPT) Adequacy of treatment Duration of treatment Dosage of medication Solo therapy versus dual therapy Behavioral factors Personality disorder Psychosocial stressors Compliance Education provided Diagnosis Missed medical conditions Nonadherence (33-81%) facilitated by: Preference for different treatment (e.g. no medications) Complexity of medication regimen Cost (e.g. too expensive so skip doses) Side effects (e.g. too severe) Cognitive impairment (i.e. noncompliance) Patterns: underuse, overuse, altered use Recognition and treatment is poor-missed in 50% of the ambulatory population Among those treated, treated “inappropriately”: Inappropriate use of medications Too low doses for fear of side effects Too short duration Inadequate followup (don’t see often enough) Delusional depression is more prevalent in older depressives vs younger depressives Associated with: Hypochondriasis Delusional relapses Worse response to monotherapy Longer hospitalizations Higher relapse rates Optimize current therapy Switch therapy to new agent Augment with additional medication or co- prescribe ECT Switch Augmentation Slower Quicker Simpler, less costly More complex, Avoids drug-drug interaction Reduces SE Introduce “different mechanism” costly Risks drug-drug interaction Can increase SE Avoids loss of earlier partial response Venlafaxine when ANXIETY is prominent Bupropion when APATHY is prominent Mirtazapine when INSOMNIA/ANXIETY are prominent Aripiprazole is atypical antipsychotic approved for major depressive disorder and bipolar disorder Challenging in treating depressed older adults who have not responded to multiple trials of antidepressant medications Elderly with psychotic symptoms who failed antidepressant therapy often do respond to ECT Some studies suggest that ECT is in fact the SUPERIOR treatment in late life compared to midlife Underused! Some indications: Antidepressant intolerance and/or nonresponse Prior positive response to ECT Psychosis Catatonia Mania Profound weight loss Relative contraindications: Cardiac: Recent MI, unstable angina, uncompensated CHF, arrhythmias, severe valvular disease Neurologic: intracranial lesions “increase” risk, recent CVA Major concern of patients (transient retrograde amnesia) ECT may improve depression-impaired cognition but exacerbate impaired cognition of dementia Preparation: Education Pre-screen to establish baseline Monitor memory throughout treatment Decrease treatment frequency when pronounced The diagnosis of late-life depression is as valid as any other significant medical disorder. MDD in seniors is associated with psychiatric and medical morbidity, increased utilization of health care, and increased mortality. Late-life depression is treatable but may be refractory to a single intervention. Late-life depression often coexists with cognitive impairment.
