Caregiver depression: Addressing a growing mental health issue
I see symptoms of depression among people who are caring for loved ones at home all the time, and I consider it a major public health problem. The statistics that we have indicate one in four U.S. households provide care for aging loved ones, and some studies indicate as many as half of these caregivers experience some degree of depression.
I consider [caregiver depression] a major public health problem
What are the signs?
Depression occurs among caregivers
about 10 times more often than in the general population. About
60 percent of caregivers present with some symptoms of depression,
and 30 to 40 percent of them are considered to have major depression.
The following are the nine classic symptoms a physician looks
for when considering a diagnosis of depression. A major depressive
episode is present if five or more of the following nine symptoms
are present during the same two-week period. At least one of the
five symptoms must be either a depressed mood or loss of interest
or pleasure.
-
Persistent sadness or unhappiness
-
Fatigue or loss
of energy
-
Loss of interest in previously enjoyable
activities
-
Irritability or agitation
-
Sudden change in appetite or weight
-
Disruption of normal sleep pattern
-
Feelings of worthlessness or excessive or inappropriate
guilt
-
Difficulty thinking clearly or concentrating
-
Thoughts of suicide or death
Aging caregivers are often difficult to diagnose because they
may not present with these typical symptoms of depression. They
may visit their doctor with complaints of backaches or headaches
and general fatigue. Experts estimate primary care physicians miss
between 30 and 50 percent of the cases of depression among their
aging caregiver patients.
Depression is a significant risk factor
for chronic medical conditions such as heart disease, cancer and diabetes.
What are the long-term consequences?
In addition to the personal anguish
depressed individuals experience, high rates of depressive symptoms put
people at serious risk with their physical health as well. Depression
is a significant risk factor for chronic medical conditions such as heart
disease, cancer and diabetes. One study found that older caregiving spouses
who reported strain due to caregiving experience a 63 percent higher mortality
rate than older spouses who were not caregivers.
Depression is the second highest risk factor for death among heart
patients, second only to a weak ejection fraction. Thirty to 50 percent
of heart patients suffer from depression, and they are six times more
likely to die than heart disease patients who are not depressed.
Patients who are being cared for by depressed individuals are also
at risk. They may not be given medications regularly, and they are more
likely to be placed in nursing homes and other institutionalized settings,
which costs society an estimated $200 billion each year.
What factors influence caregiver depression?
Research
has shown us that certain patient characteristics increase the caregiver's
risk of depression. Those who care for people younger than 65 years
old who suffer from multiple medical problems resulting in their inability
to perform two or more activities of daily living such as feeding themselves
or personal hygiene are at the greatest risk. Additional risk factors
include angry or aggressive behavior on the part of the patient.
Treatment
The good news is that effective treatment is available. Counseling
and/or medication is effective in treating 90 percent of those suffering
depression, but early intervention is important. The longer and more
severe the depression, the greater the health risk to the individual
and the less likely they will recover.
Family members should be alert to signs of depression among the caregivers in their families and urge people to seek treatment as soon as possible
What to do?
Oftentimes, caregivers don't seek help for their depression
because they assume it is a natural consequence of caring for chronically
ill loved ones and can't be helped. Family members should be alert to
signs of depression among the caregivers in their families and urge
people to seek treatment as soon as possible.
Respite programs that give family members a break from their caregiving
responsibilities helps as well. Families should come up with a plan
to regularly relieve caregivers so they have time to take care of themselves
and enjoy other activities. Research has found that caregivers who use
adult day care services decreased their own care-related stress and
depressive symptoms significantly.
Several programs are aimed at primary care physicians who may be best
positioned to recognize and treat caregivers. Tools such as the scale
developed by Dr. Prigerson can be helpful in identifying those most
at risk.
There are also several national programs directed at supporting those
who care for patients at home. The U.S. Department of Health and Human
Services and the Robert Wood Johnson Foundation has funded a demonstration
project in three states that issues monthly cash allowances for Medicaid
recipients to hire their own caregivers, including members of their
families and friends.
Public policy decision makers are grappling with ways to support and
sustain those who are the backbone of our long-term care systemfamily
and informal caregivers who take care of loved ones at home.
