Module 3: Depression in Older Adults > Lecture Notes
- There are an estimated 430,000 adults aged 65+ with one or more
serious mental health conditions in metropolitan New York City
- This
population includes individuals with long-term psychiatric conditions,
and those with late life diagnoses such as depression and anxiety,
cognitive impairment (e.g., dementia and Alzheimer's disease) or
substance abuse disorders
- The most prevalent mental health conditions among older
adults are:
- Depression
- Dementia
- Paranoia
- Anxiety
- Depression in older adults is a significant public health
problem
- Depression
is one of the most common (and most well-researched) mental disorders
in older adults: Prevalence ranges from 1% in physically well
individuals to 50% in those living with medical illness
- Over 2
million individuals over the age of 65 (or 5% of the 34 million older
adults in the United States) suffer from some form of depressive illness
- Among community dwelling older adults, an estimated:
- 27 % experience significant depressive symptoms
- .1 - 1.8% experience major depressive
disorder
- 20 % experience significant anxiety symptoms
- Most common diagnosis: Major
Depressive Disorder
- Prevalence
rates differ according to residence: 1-3% in community settings; 5-9%
in primary care; 12-30% in institutional settings (Unutzer et al., 1997)
- Rates
of depression are significantly higher among medically ill or frail
elders (10-43%) (Steffans et al., 2000); Rates are also higher among
women and Latinos, and they increase with age
- Depression
affects overall functioning: For example, elders who are depressed take
longer to recover from hip fracture or a stroke and medical hospital
stays among older adults who are depressed is often twice as long as
those who are not depressed; Untreated depression can lead to greater
disability
- Older adults are more likely to complain about
problems with memory and problem-solving than feelings of
depression. This may lead physicians and other professionals
to
assume that they have dementia (pseudodementia) instead of depression.
- Depression
can be persistent, intermittent or recurrent, and result in significant
physical and psychological comorbidity and functional impairment
- Depression
is also the most common psychological consequence of caregiving for
elder family members; Among caregivers for older adults with dementia,
depression rates are as high as 52%, nearly 3x the rate among
non-caregivers of the same age (Tennstedt, 1999)
- Depression is a
spectrum disorder and ranges from subsyndromal depression (mild or
subclinical depression) to dysthymia and major depression.
- Subsyndromal,
or mild depression is a level of depression that does not meet the
criteria for dysthymia or major depression as defined in the Diagnostic
Manual of Mental Disorders (DSM IV-TR).
- High rates of
subsyndromal depression are reported among elders. An
estimated
13%-27% of community-dwelling elders and as many as 50% of nursing home
residents suffer from mild depression.
- Elders may be depressed without verbally expressing
feelings of depression; this is known as "masked depression."
- Elders with "masked depression" may:
- Complain of vague physical pain, bodily discomfort, sleep
disturbance, and problems of memory,
- Show signs of apathy, and
- Withdraw from others without expressing mood changes.
Dysthymia
Diagnosis of Dysthymic Disorder
Summarized from the Diagnostic and Statistical Manual of Mental
Disorders- Fourth Edition
- A person has depressed mood for most of the time almost every
day for at
least two years. Children and adolescents may have irritable mood, and
the time frame is at least one year.
- While depressed, a person experiences at least two of the
following symptoms:
- Either overeating or lack of appetite.
- Sleeping too much or having difficulty sleeping.
- Fatigue, lack of energy.
- Poor self-esteem.
- Difficulty with concentration or decision making.
- Feeling hopeless.
- A person has not been free of the symptoms during the
two-year time period (one-year for children and adolescents).
- During the two-year time period (one-year for children and
adolescents) there has not been a major depressive episode.
- A person has not had a manic, mixed, or hypomanic episode.
- The symptoms are not present only during the presence of
another chronic disorder.
- A medical condition or the use of substances (i.e.,
alcohol, drugs, medication, toxins) do not cause the symptoms.
- The person's symptoms are a cause of great distress or
difficulty in functioning at home, work, or other important areas.
Diagnosis of Major Depressive Disorder, Single Episode
Summarized from the Diagnostic and Statistical Manual of Mental
Disorders- Fourth Edition
- The person experiences a single major depressive
episode:
- For
a major depressive episode a person must have experienced at least five
of the nine symptoms below for the same two weeks or more, for most of
the time almost every day, and this is a change from his/her prior
level of functioning. One of the symptoms must be either (a) depressed
mood, or (b) loss of interest.
- Depressed mood. For children and adolescents, this may
be irritable mood.
- A significantly reduced level of interest or pleasure
in most or all activities.
- A
considerable loss or gain of weight (e.g., 5% or more change of weight
in a month when not dieting). This may also be an increase or decrease
in appetite. For children, they may not gain an expected amount of
weight.
- Difficulty falling or staying asleep (insomnia), or
sleeping more than usual (hypersomnia).
- Behavior that is agitated or slowed down. Others should
be able to observe this.
- Feeling fatigued, or diminished energy.
- Thoughts of worthlessness or extreme guilt (not about
being ill).
- Ability to think, concentrate, or make decisions is
reduced.
- Frequent thoughts of death or suicide (with or without
a specific plan), or attempt of suicide.
- The person's symptoms do not indicate a mixed episode.
- The person's symptoms are a cause of great distress or
difficulty in functioning at home, work, or other important areas.
- The person's symptoms are not caused by substance use
(e.g., alcohol, drugs, medication), or a medical disorder.
- The
person's symptoms are not due to normal grief or bereavement over the
death of a loved one, they continue for more than two months, or they
include great difficulty in functioning, frequent thoughts of
worthlessness, thoughts of suicide, symptoms that are psychotic, or
behavior that is slowed down (psychomotor retardation).
- Another disorder does not better explain the major
depressive episode.
- The person has never had a manic, mixed, or hypomanic
episode (unless
an episode was due to a medical disorder or use of a substance).
Biomedical risk factors:
- Chronic physical illness and conditions
- Chronic physical pain
- Neurological or cognitive deficits
- Poor nutrition
Psychological and social risk factors:
- Multiple losses (e.g. loss of loved ones, loss of social
roles, and financial decline)
- Adverse life events and stress (e.g. bereavement, forced
retirement, trauma),
- Social isolation and lack of social support
- Lack of socioeconomic resources and income (poverty)
- Societal oppression and discrimination
- Past history of depression or alcohol and other substance
abuse
- Medical
conditions that produce depressive symptoms include: Parkinson's
disease, Alzheimer's disease and dementia, rheumatoid arthritis,
thyroid dysfunction, diseases of the adrenal glands, strokes, heart
disease, hypothyroidism, vitamin deficiencies, cancer, HIV disease, and
chronic infection
- Medication interactions can also produce symptoms of
depression
- It
is important to distinguish between symptoms related to medical
conditions or medications, depression, delirium or dementia, and
changes related to normal aging
- Psychological comorbidities include
anxiety, substance abuse and eating disorders, borderline personality
disorder and somatization (Stephanis & Stephanis, 1999)
- 1 out of 3 people with depression suffer from some form of
substance abuse or dependence
- Life
events that can trigger depression (i.e., the death of a spouse or
partner, loss of status, and chronic health problems) can also lead to
substance abuse
- Social workers should be aware that alcohol and
medications that are prescribed for conditions such as insomnia,
anxiety and chronic pain can be used by elders as a way to counteract
feelings of depressionw
- More
women than men suffer from depression and anxiety disorders.
Women are more likely than men to express feelings of
sadness.
Men, on the other hand, are more likely than are women to mask feelings
of depression with alcohol and drugs.
- Changes in hormone levels during menopause can impact
depression in women.
- Men
tend to be affected by financial and work-related stressors while women
are more reactive to events occurring in their social networks.
- Older minorities are less likely to receive mental health
services.
- The
recognition, definition, experiences and expression of depressive
symptoms differ among people of different races and
ethnicity.
Mental health services have not been sensitive enough to these
differences.
- It is important to understand how culture and
ethnicity affect emotional disorders. The ways in which people present
symptoms are often influenced by culture. Professionals must be careful
of using terms such as 'depression', 'sadness' and 'anxiety' in
eliciting or describing clients' symptoms because clients may have
other ways of expressing symptoms of depression.
- The way in which
different racial and ethnic groups interpret and present symptoms of
illness may be a factor in the varied levels of depression.
- Ethnic elders are underrepresented in epidemiological
studies.
- African
American, Asian American and some Latino groups report physical
symptoms of depression while non-Hispanic whites frequently report
dysphoria.
- Common symptoms:
- Overwhelming or persistent sadness, anxiety,
"empty" mood
- Depressed affect: Loss of interest or pleasure in common
activities
- Decreased energy, fatigue
- Eating changes or problems; Unintentional weight gain or
loss
- Change in sleep patterns, or sleep disturbances :
- Difficulty falling asleep (initial insomnia)
- Multiple awakenings throughout the night (middle insomnia)
- Early morning awakening (terminal insomnia)
- Feelings of hopelessness, worthlessness, helplessness
- Abnormal thoughts, excessive or inappropriate guilt
- Irritability, agitation, frequent outbursts of temper or
crying
- Difficulty concentrating and memory loss
- Thoughts of suicide or death; Suicidal plans or actual
attempt
- Importance
of differential diagnosis that rules out depressive episodes based on
co-occurring medical conditions or substance use disorders
- Commonly used assessment instruments with older adults
include:
- Geriatric Depression Scale (GDS; Sheikh &
Yesavage, 1986)
- Center for Epidemiological Studies Depression Scale
(CES-D; Mojtabai & Olfson, 2004)
- Hamilton Depression Rating Scale (HAM-D; Hamilton, 1960;
Rapp et al., 1990)
- Beck Depression Inventory-II (BDI-II; Beck, Steer
& Brown, 1996)
- Primary Care Evaluations of Mental Disorders (PRIME-MD;
Spitzer, et al., 1995)
- Approximately
60% of all people who die by suicide suffer from major depression (if
alcoholics are included, the rate rises to 75%) (AFSP.org, 2007)
- Suicide
rates are higher in individuals over 65 than in any other age group
(primarily among white men); Risks include depression, multiple losses
and bereavement, social isolation, physical illness,
alcoholism
and drug abuse, race/ethnicity (white elders higher rates than elders
of color) and gender (males much higher rates)
- Suicide attempts are most likely to be successful after age
50 (Gelles, 2005)
- "Slow suicide": subtle, often undiagnosed, attempts to end
one's life (e.g., self-starvation, medication overdose, etc.)
- Treatment:
Take a proactive
and direct role, focus on resolving current crisis,
remove any immediate dangers (e.g., guns, stockpiled
medications)
and make short-term safety contract with suicidal individual; Involve
others in individual's immediate social network by informing of suicide
risk and safety plans
- Signs of suicidal intent (NOTE: Take ALL suicidal thoughts seriously,
but assess for lethality by looking for the following):
- History of suicidal attempts, or family history of suicide
- A suicide plan (the more specific and feasible the plan,
the higher the lethality)
- Stockpiling medications
- Sudden change of will or funeral plans
- Giving away possessions
- Sudden calm or peacefulness after long period of anxiety,
agitation or depression
- Verbalizations about desire to die, or worthlessness of
life (less frequent in older adults)
- Early screening, case management and collaboration with all
involved in medical treatment is essential to appropriate management
- Use of integrated, interdisciplinary, geriatrically-trained
health-care team is best practice with this population
- Evidence-based
treatments include cognitive-behavioral, psychoeducation, interpersonal
psychotherapy, integrated team treatment and problem-solving approaches
as adjuncts to psychopharmacological antidepressants (i.e., SSRIs and
tricyclics)
- Other promising treatments include exercise, cognitive
bibliotherapy, reminiscence and mindfulness-based
interventions;
ECT has been found to be helpful in cases where older adults are
suicidal and unresponsive to medication and psychosocial treatments
- Depression
is often a familial illness: Provide opportunities for support and
respite for family members of depressed elders, and for caregivers who
are themselves depressed
- Communicate empathy and compassion through verbal and
non-verbal encouragement
- Encourage and elicit expression of feelings, no matter how
difficult they may be to hear
- Reflect content and feelings, and seek clarification of
client concerns
- Mirror rate and volume of elder's speech; Use simple,
concise and direct language
- Respect client's defenses as a survival mechanism
- Assess for depression and suicidality; Explore possible
biological and psychological/social factors in depression
- Emphasize client strengths and positive self-statements
- Introduce short-term, manageable goals and tasks
- Use reality-testing and reminiscence tentatively -- may be too vulnerable
- Seek out supervision and monitor your own responses to the
work; Make a self-care plan
- Be patient and expect recovery to be slow and intermittent
- Avoid:
- Cajoling, or trying to talk client out of depression
- Giving advice or being unduly directive
- Extensive probing or questioning, use of "why" questions
- Blaming client for being depressed
