Review the diagnostic criteria for depression
Increase awareness of the prevalence and consequences of untreated depression in the older adult
Depression is under-recognized and undertreated in the older adult
Many older adults who die by suicide (up to 75%) suffer with depression and most visited a physician within a month before death
Untreated depression can delay recovery or worsen the outcome of other medical illnesses via increased morbidity or mortality
Depression is NOT a part of normal aging
DSM-IV-TR Definition
Five or more of the following must have been present during the same 2-week interval and represent a change from baseline functioning
One(1) of the symptoms must be depressed mood or loss of interest or pleasure
DSM-IV-TR (“core symptoms”; occur most of the day nearly every day)
Depressed mood
Loss of interest in all or almost all activities or pleasure (anhedonia)
Appetite change or weight loss
Insomnia or hypersomnia
Psychomotor agitation or retardation
DSM-IV-TR
Loss of energy or fatigue
Feelings of worthlessness or excessive guilt
Difficulty with thinking, concentration, or decision making
Recurrent thoughts of death or suicide
Depression without sadness
Lack of feeling or emotion
Prominent cognitive compliants
prominent somatic compliants
Multiple primary care visits without resolution of problem
Social withdrawal,avoidance of social intraction
For Major Depression, these symptoms
Produce social impairment
Are not related to substance abuse
Are not related to bereavement
Types of Depressive Disorders (DSM-IV)
Mild episode of major depression
Moderate episode of major depression
Severe episode of major depression
Severe episode of major depression with psychotic features
Minor depression is common
15% of older persons
Causes
use of health services, excess disability, poor health outcomes, including
mortality
Major depression is not common
1%–2% of physically healthy community dwellers
Elders less likely to recognize or endorse depressed mood
Classical major depression is less frequent:
M.d.d about 1-2%
Dysthymic disorder 2%
Depressive symptoms 15-25%
Medically ill
Disabled and institutionalized elderly
Spousal death
Older adult with malignancies,neurologic and endocrine: one half of post strok,onefourth of cancer inpatients, one third of MI
-
Alcohol or substance abuse
Current use of a medication associated with a high risk of depression
Hearing or vision impairment severe enough to affect function
History of attempted suicide
History of psychiatric hospitalization
Medical diagnosis or diagnoses associated with a high risk of depression
change of environment
New stressful losses (loss of autonomy, privacy, functional status, body part, family member or friend)
Personal or family history of depression or mood disorder

Pt often unconcerned
Pt denies/unaware of deficits
Not depressed
Can experience pleasure

Psychiatric disorders:
Medical illness especial neurological disease
Goals of therapy: improve mood, function, and quality of life
Goals of treatment of an acute depressive episode are to achieve recovery and prevent future episodes of depression
The intended outcome should be complete resolution of symptoms, not simply a reduction in depressive symptoms.
Three phases of treatment are generally required to achieve these goals.
Acute Phase (reverse current episode)
Duration: about 3 months: Goal is complete recovery from signs and sx of acute episode
Continuation Phase (prevent a relapse)
Duration: 4-6 months: Goal is to prevent relapse as sx continue to decline and functionality improves
Maintenance Phase (prevent future recurrence)
Duration: 3 months or longer: Goal is to prevent recurrence of a new depressive episode
Pharmacotherapy
Psychotherapy
Electroconvulsive therapy (ECT)
Patients should be monitored for response to treatment by:
Observation for resolution of signs and symptoms of depression
Also monitor patients carefully for side effects and interactions with other medications
50-60% improve with antidepressants
Age related change influence pharmakietic:
Longer time for response
More side effects
Depends :
Psychiatric co morbidity
Medical illness
But , drug of choice
SSRIS
Sertraline:25-50mg daily
Fluoxetine:10 mg
Citalopram :10mg
Less intraction :sertraline and citalopram
Fluoxetine increase nortriptyline,verapamil,B blokers
Better tolerated than tricyclics
SIADH at high doses and sexual side effects
Interact with CYP-450 isoenzymes by inhibition
Can increase the anticoagulant effect of warfarin
Do not discontinue abruptly; taper the dose
,
Antidepressants (SSRIs continued)
Nausea and diarrhea might occur
Fluoxetine is not a preferred drug for use in the elderly due to a prolonged half life (4-6 days; metabolite 9.3 days) and potential for many drug interactions . It might also induce anxiety, sleep disturbance, and/or agitation
Paroxetine is also not favored due to anti-cholinergic properties and other effects noted with fluoxetine
TCA : nortriptyline.desipramine
Caution: cardiac .prostatic,glaucoma,cognitive,falling risk
10-25mg
Potential for anticholinergic and sedative effects
Avoid in pts. who are prone to constipation, orthostatic hypotension, glaucoma, or who have BPH
May cause ventricular conduction delays and heart block
May be fatal in overdose
SNRI: Velnafaxin 37/5mg_75mg up 112.5-225mg
Caution :hypertention
Side effects:nausea,(slow titration)
special for chronic pain
Cognitive-behavioral
Interpersonal
Short-term psychodynamic
Life review, reminisce
Problem solving
Supportive
Bereavement therapy
Behavioral
Dialectical-behavioral therapy
Risk factors for suicide:
depression older age
physical illness living alone (single, divorced, or separated and without children) male gender drug abuse or alcoholism having a personal or family history of suicide attempt severe anxiety or stress specific plan with access to firearms or other means.
In older adults, depression is:
Common (especially “minor” depression)
Associated with morbidity
Difficult to diagnose because of atypical presentation, more somatic concerns, overlap with symptoms of other illnesses
Differential diagnoses include other medical illnesses, dementia, bereavement
Suicide is a serious concern in depressed older patients, particularly older white males
Treatment (acute & preventive) should be individualized and may include:
Pharmacotherapy
Psychotherapy
ECT
Choice of antidepressant should be based on comorbidities, side-effect profiles, patient sensitivity, potential drug interactions
