TYPES OF DEPRESSION
Depressive disorders come in
different forms, just as is the case with other illnesses such as heart disease. This pamphlet
briefly describes three of the most common types of depressive disorders. However, within these
types there are variations in the number of symptoms, their severity, and persistence.
Major
depression is manifested by a combination of symptoms (see symptom list)
that interfere with the ability to work, study, sleep, eat, and enjoy once pleasurable
activities. Such a disabling episode of depression may occur only once but more commonly occurs
several times in a lifetime.
A less severe type of depression, dysthymia, involves long-term, chronic
symptoms that do not disable, but keep one from functioning well or from feeling good. Many
people with dysthymia also experience major depressive episodes at some time in their lives.
Another
type of depression is bipolar disorder, also called manic-depressive
illness. Not nearly as prevalent as other forms of depressive disorders, bipolar disorder is
characterized by cycling mood changes : severe highs (mania) and lows (depression). Sometimes
the mood switches are dramatic and rapid, but most often they are gradual. When in the depressed
cycle, an individual can have any or all of the symptoms of a depressive disorder. When in the
manic cycle, the individual may be overactive, overtalkative, and have a great deal of energy.
Mania often affects thinking, judgment, and social behavior in ways that cause serious problems
and embarrassment. For example, the individual in a manic phase may feel elated, full of grand
schemes that might range from unwise business decisions to romantic sprees. Mania, left
untreated, may worsen to a psychotic state.
SYMPTOMS OF DEPRESSION AND MANIA
Not
everyone who is depressed or manic experiences every symptom. Some people experience a few
symptoms, some many. Severity of symptoms varies with individuals and also varies over time.
Depression
- Persistent sad, anxious, or "empty" mood
- Feelings of hopelessness, pessimism
- Feelings of guilt, worthlessness, helplessness
- Loss of interest or pleasure in hobbies and activities that were once enjoyed, including
sex
- Decreased energy, fatigue, being "slowed down"
- Difficulty concentrating, remembering, making decisions
- Insomnia, early-morning awakening, or oversleeping
- Appetite and/or weight loss or overeating and weight gain
- Thoughts of death or suicide; suicide attempts
- Restlessness, irritability
- Persistent physical symptoms that do not respond to treatment, such as headaches, digestive
disorders, and chronic pain
MANIA
- Abnormal or excessive elation
- Unusual irritability
- Decreased need for sleep
- Grandiose notions
- Increased talking
- Racing thoughts
- Increased sexual desire
- Markedly increased energy
- Poor judgment
- Inappropriate social behavior
CAUSES OF DEPRESSION
Some types
of depression run in families, suggesting that a biological vulnerability can be
inherited. This seems to be the case with bipolar disorder. Studies of families in which members
of each generation develop bipolar disorder found that those with the illness have a somewhat
different genetic makeup than those who do not get ill. However, the reverse is not true: Not
everybody with the genetic makeup that causes vulnerability to bipolar disorder will have the
illness. Apparently additional factors, possibly stresses at home, work, or school, are involved
in its onset.
In
some families, major depression also seems to occur generation after generation. However, it
can also occur in people who have no family history of depression. Whether inherited or not,
major depressive disorder is often associated with changes in brain structures or brain
function.
People
who have low self-esteem, who consistently view themselves and the world with pessimism
or who are readily overwhelmed by stress, are prone to depression. Whether this represents a
psychological predisposition or an early form of the illness is not clear.
In
recent years, researchers have shown that physical changes in the body can be accompanied by
mental changes as well. Medical illnesses such as stroke, a heart attack, cancer, Parkinson's
disease, and hormonal disorders can cause depressive illness, making the sick person apathetic
and unwilling to care for his or her physical needs, thus prolonging the recovery period. Also,
a serious loss, difficult relationship, financial problem, or any stressful (unwelcome or
even desired) change in life patterns can trigger a depressive episode. Very often, a
combination of genetic, psychological, and environmental factors is involved in the onset of a
depressive disorder. Later episodes of illness typically are precipitated by only mild stresses,
or none at all.
Depression in Women
Women
experience depression about twice as often as men. Many hormonal factors may contribute to
the increased rate of depression in women-particularly such factors as menstrual cycle changes,
pregnancy, miscarriage, postpartum period, pre-menopause, and menopause. Many women also
face additional stresses such as responsibilities both at work and home, single parenthood, and
caring for children and for aging parents.
A
recent NIMH study showed that in the case of severe premenstrual syndrome (PMS), women with a
preexisting vulnerability to PMS experienced relief from mood and physical symptoms when their
sex hormones were suppressed. Shortly after the hormones were re-introduced, they again
developed symptoms of PMS. Women without a history of PMS reported no effects of the hormonal
manipulation.
Many
women are also particularly vulnerable after the birth of a baby. The hormonal and physical
changes, as well as the added responsibility of a new life, can be factors that lead to
postpartum depression in some women. While transient "blues" are common in new mothers, a
full-blown depressive episode is not a normal occurrence and requires active intervention.
Treatment by a sympathetic physician and the family's emotional support for the new mother are
prime considerations in aiding her to recover her physical and mental well-being and her ability
to care for and enjoy the infant.
Depression in Men
Although
men are less likely to suffer from depression than women, 3 to 4 million men in the
United States are affected by the illness. Men are less likely to admit to depression, and
doctors are less likely to suspect it. The rate of suicide in men is four times that of women,
though more women attempt it. In fact, after age 70, the rate of men's suicide rises, reaching a
peak after age 85.
Depression
can also affect the physical health in men differently from women. A new study shows
that, although depression is associated with an increased risk of coronary heart disease in both
men and women, only men suffer a high death rate.
Men's
depression is often masked by alcohol or drugs, or by the socially acceptable habit of
working excessively long hours. Depression typically shows up in men not as feeling hopeless and
helpless, but as being irritable, angry, and discouraged; hence, depression may be difficult to
recognize as such in men. Even if a man realizes that he is depressed, he may be less willing
than a woman to seek help. Encouragement and support from concerned family members can make a
difference. In the workplace, employee assistance professionals or worksite mental health
programs can be of assistance in helping men understand and accept depression as a real illness
that needs treatment.
DEPRESSION IN THE ELDERLY
Some
people have the mistaken idea that it is normal for the elderly to feel depressed. On the
contrary, most older people feel satisfied with their lives. Sometimes, though, when depression
develops, it may be dismissed as a normal part of aging. Depression in the elderly, undiagnosed
and untreated, causes needless suffering for the family and for the individual who could
otherwise live a fruitful life. When he or she does go to the doctor, the symptoms
described are usually physical, for the older person is often reluctant to discuss feelings of
hopelessness, sadness, loss of interest in normally pleasurable activities, or extremely
prolonged grief after a loss.
Recognizing
how depressive symptoms in older people are often missed, many health care
professionals are learning to identify and treat the underlying depression. They recognize that
some symptoms may be side effects of medication the older person is taking for a physical
problem, or they may be caused by a co-occurring illness. If a diagnosis of depression is made,
treatment with medication and/or psychotherapy will help the depressed person return to a
happier, more fulfilling life. Recent research suggests that brief psychotherapy (talk therapies
that help a person in day-to-day relationships or in learning to counter the distorted negative
thinking that commonly accompanies depression) is effective in reducing symptoms in short-term
depression in older persons who are medically ill. Psychotherapy is also useful in older
patients who cannot or will not take medication. Efficacy studies show that late-life depression
can be treated with psychotherapy.
Improved
recognition and treatment of depression in late life will make those years more
enjoyable and fulfilling for the depressed elderly person, the family, and caretakers.
Depression in Children
Only
in the past two decades has depression in children been taken very seriously. The depressed
child may pretend to be sick, refuse to go to school, cling to a parent, or worry that the
parent may die. Older children may sulk, get into trouble at school, be negative, grouchy, and
feel misunderstood. Because normal behaviors vary from one childhood stage to another, it can be
difficult to tell whether a child is just going through a temporary "phase" or is suffering from
depression. Sometimes the parents become worried about how the child's behavior has changed, or
a teacher mentions that "your child doesn't seem to be himself." In such a case, if a visit to
the child's pediatrician rules out physical symptoms, the doctor will probably suggest that the
child be evaluated, preferably by a psychiatrist who specializes in the treatment of children.
If treatment is needed, the doctor may suggest that another therapist, usually a social worker
or a psychologist, provide therapy while the psychiatrist will oversee medication if it is
needed. Parents should not be afraid to ask questions: What are the therapist's qualifications ?
What kind of therapy will the child have? Will the family as a whole participate in therapy ?
Will my child's therapy include an antidepressant? If so, what might the side effects be?
The
National Institute of Mental Health (NIMH) has identified the use of medications for
depression in children as an important area for research. The NIMH-supported Research Units on
Pediatric Psychopharmacology (RUPPs) form a network of seven research sites where clinical
studies on the effects of medications for mental disorders can be conducted in children and
adolescents. Among the medications being studied are antidepressants, some of which have been
found to be effective in treating children with depression, if properly monitored by the child's
physician.
DIAGNOSTIC EVALUATION AND TREATMENT
The
first step to getting appropriate treatment for depression is a physical examination by a
physician. Certain medications as well as some medical conditions such as a viral infection can
cause the same symptoms as depression, and the physician should rule out these possibilities
through examination, interview, and lab tests. If a physical cause for the depression is ruled
out, a psychological evaluation should be done, by the physician or by referral to a
psychiatrist or psychologist.
A
good diagnostic evaluation will include a complete history of symptoms, i.e., when they
started, how long they have lasted, how severe they are, whether the patient had them before
and, if so, whether the symptoms were treated and what treatment was given. The doctor should
ask about alcohol and drug use, and if the patient has thoughts about death or suicide. Further,
a history should include questions about whether other family members have had a depressive
illness and, if treated, what treatments they may have received and which were effective.
Last,
a diagnostic evaluation should include a mental status examination to determine if speech
or thought patterns or memory have been affected, as sometimes happens in the case of a
depressive or manic-depressive illness.
Treatment
choice will depend on the outcome of the evaluation. There are a variety of
antidepressant medications and psychotherapies that can be used to treat depressive disorders.
Some people with milder forms may do well with psychotherapy alone. People with moderate to
severe depression most often benefit from antidepressants. Most do best with combined treatment
: medication to gain relatively quick symptom relief and psychotherapy to learn more effective
ways to deal with life's problems, including depression. Depending on the patient's diagnosis
and severity of symptoms, the therapist may prescribe medication and/or one of the several forms
of psychotherapy that have proven effective for depression.
Electroconvulsive
therapy (ECT) is useful, particularly for individuals whose depression is
severe or life threatening or who cannot take antidepressant medication. ECT often is effective
in cases where antidepressant medications do not provide sufficient relief of symptoms. In
recent years, ECT has been much improved. A muscle relaxant is given before treatment, which is
done under brief anesthesia. Electrodes are placed at precise locations on the head to deliver
electrical impulses. The stimulation causes a brief (about 30 seconds) seizure within the
brain. The person receiving ECT does not consciously experience the electrical stimulus. For
full therapeutic benefit, at least several sessions of ECT, typically given at the rate of three
per week, are required.
Medications
There
are several types of antidepressant medications used to treat depressive disorders. These
include newer medications-chiefly the selective serotonin reuptake inhibitors (SSRIs) - the
tricyclics, and the monoamine oxidase inhibitors (MAOIs). The SSRIs-and other newer medications
that affect neurotransmitters such as dopamine or norepinephrine - generally have fewer side
effects than tricyclics. Sometimes the doctor will try a variety of antidepressants before
finding the most effective medication or combination of medications. Sometimes the dosage must
be increased to be effective. Although some improvements may be seen in the first few weeks,
antidepressant medications must be taken regularly for 3 to 4 weeks (in some cases, as many as
8 weeks) before the full therapeutic effect occurs.
Patients
often are tempted to stop medication too soon. They may feel better and think they no
longer need the medication. Or they may think the medication isn't helping at all. It is
important to keep taking medication until it has a chance to work, though side effects may
appear before antidepressant activity does. Once the individual is feeling better, it is
important to continue the medication for at least 4 to 9 months to prevent a recurrence of the
depression. Some medications must be stopped gradually to give the body time to adjust.
Never stop taking an antidepressant without consulting the doctor for
instructions on how to safely discontinue the medication. For individuals with bipolar
disorder or chronic major depression, medication may have to be maintained indefinitely.
Antidepressant
drugs are not habit-forming. However, as is the case with any type of medication
prescribed for more than a few days, antidepressants have to be carefully monitored to see if
the correct dosage is being given. The doctor will check the dosage and its effectiveness
regularly.
For
the small number of people for whom MAO inhibitors are the best treatment, it is necessary
to avoid certain foods that contain high levels of tyramine, such as many cheeses, wines, and
pickles, as well as medications such as decongestants. The interaction of tyramine with MAOIs
can bring on a hypertensive crisis, a sharp increase in blood pressure that can lead to a
stroke. The doctor should furnish a complete list of prohibited foods that the patient should
carry at all times. Other forms of antidepressants require no food restrictions.
Medications
of any kind - prescribed, over-the counter, or borrowed -
should never be mixed without consulting the doctor. Other health professionals who may
prescribe a drug - such as a dentist or other medical specialist - should be told of the
medications the patient is taking. Some drugs, although safe when taken alone can, if taken with
others, cause severe and dangerous side effects. Some drugs, like alcohol or street drugs, may
reduce the effectiveness of antidepressants and should be avoided. This includes wine, beer, and
hard liquor. Some people who have not had a problem with alcohol use may be permitted by their
doctor to use a modest amount of alcohol while taking one of the newer antidepressants.
Antianxiety
drugs or sedatives are not antidepressants. They are sometimes prescribed along with
antidepressants; however, they are not effective when taken alone for a depressive disorder.
Stimulants, such as amphetamines, are not effective antidepressants, but they are used
occasionally under close supervision in medically ill depressed patients.
Questions
about any antidepressant prescribed, or problems that may be related to the
medication, should be discussed with the doctor.
Lithium
has for many years been the treatment of choice for bipolar disorder, as it can be
effective in smoothing out the mood swings common to this disorder. Its use must be carefully
monitored, as the range between an effective dose and a toxic one is small. If a person has
preexisting thyroid, kidney, or heart disorders or epilepsy, lithium may not be recommended.
Fortunately, other medications have been found to be of benefit in controlling mood swings.
Among these are two mood-stabilizing anticonvulsants, carbamazepine (Tegretol®) and
valproate (Depakote®). Both of these medications have gained wide acceptance in
clinical practice, and valproate has been approved by the Food and Drug Administration for
first-line treatment of acute mania. Other anticonvulsants that are being used now include
lamotrigine (Lamictal®) and gabapentin (Neurontin®): their role in the
treatment hierarchy of bipolar disorder remains under study.
Most
people who have bipolar disorder take more than one medication including, along with
lithium and/or an anticonvulsant, a medication for accompanying agitation, anxiety, depression,
or insomnia. Finding the best possible combination of these medications is of utmost importance
to the patient and requires close monitoring by the physician.
Side Effects
Antidepressants
may cause mild and, usually, temporary side effects (sometimes referred to as
adverse effects) in some people. Typically these are annoying, but not serious. However, any
unusual reactions or side effects or those that interfere with functioning should be reported to
the doctor immediately. The most common side effects of tricyclic antidepressants, and ways
to deal with them, are:
- Dry mouth-it is helpful to drink sips of water; chew sugarless gum; clean teeth
daily.
- Constipation-bran cereals, prunes, fruit, and vegetables should be in the diet.
- Bladder problems-emptying the bladder may be troublesome, and the urine stream may
not be as strong as usual; the doctor should be notified if there is marked difficulty or
pain.
- Sexual problems-sexual functioning may change; if worrisome, it should be discussed
with the doctor.
- Blurred vision-this will pass soon and will not usually necessitate new glasses.
- Dizziness-rising from the bed or chair slowly is helpful.
- Drowsiness as a daytime problem-this usually passes soon. A person feeling drowsy or
sedated should not drive or operate heavy equipment. The more sedating antidepressants are
generally taken at bedtime to help sleep and minimize daytime drowsiness.
The
newer antidepressants have different types of side effects:
- Headache-this will usually go away.
- Nausea-this is also temporary, but even when it occurs, it is transient after each
dose.
- Nervousness and insomnia (trouble falling asleep or waking often during the night)
- these may occur during the first few weeks; dosage reductions or time will usually resolve
them.
- Agitation (feeling jittery) - if this happens for the first time after the drug is
taken and is more than transient, the doctor should be notified.
- Sexual problems-the doctor should be consulted if the problem is persistent or
worrisome.
HERBAL THERAPY
In
the past few years, much interest has risen in the use of herbs in the treatment of both
depression and anxiety. St. John's wort (Hypericum perforatum), an herb used extensively
in the treatment of mild to moderate depression in Europe, has recently aroused interest in the
United States. St. John's wort, an attractive bushy, low-growing plant covered with yellow
flowers in summer, has been used for centuries in many folk and herbal remedies. Today
in Germany, Hypericum is used in the treatment of depression more than any other antidepressant.
However, the scientific studies that have been conducted on its use have been short-term and
have used several different doses.
Because
of the widespread interest in St. John's wort, the National Institutes of Health (NIH)
conducted a 3-year study, sponsored by three NIH components-the National Institute of Mental
Health, the National Center for Complementary and Alternative Medicine, and the Office of
Dietary Supplements. The study was designed to include 336 patients with major depression of
moderate severity, randomly assigned to an 8-week trial with one-third of patients
receiving a uniform dose of St. John's wort, another third sertraline, a selective serotonin
reuptake inhibitor (SSRI) commonly prescribed for depression, and the final third a placebo (a
pill that looks exactly like the SSRI and the St. John's wort, but has no active ingredients).
The study participants who responded positively were followed for an additional 18 weeks.
At the end of the first phase of the study, participants were measured on two scales, one for
depression and one for overall functioning. There was no significant difference in rate of
response for depression, but the scale for overall functioning was better for the antidepressant
than for either St. John's wort or placebo. While this study did not support the use of St.
John's wort in the treatment of major depression, ongoing NIH-supported research is examining a
possible role for St. John's wort in the treatment of milder forms of depression.
The
Food and Drug Administration issued a Public Health Advisory on February 10, 2000. It stated
that St. John's wort appears to affect an important metabolic pathway that is used by many drugs
prescribed to treat conditions such as AIDS, heart disease, depression, seizures, certain
cancers, and rejection of transplants. Therefore, health care providers should alert their
patients about these potential drug interactions.
Some
other herbal supplements frequently used that have not been evaluated in large-scale
clinical trials are ephedra, gingko biloba, echinacea, and ginseng. Any herbal supplement should
be taken only after consultation with the doctor or other health care provider.
PSYCHOTHERAPIES
Many
forms of psychotherapy, including some short-term (10-20 week) therapies, can help
depressed individuals. "Talking" therapies help patients gain insight into and resolve their
problems through verbal exchange with the therapist, sometimes combined with "homework"
assignments between sessions. "Behavioral" therapists help patients learn how to obtain more
satisfaction and rewards through their own actions and how to unlearn the behavioral patterns
that contribute to or result from their depression.
Two
of the short-term psychotherapies that research has shown helpful for some forms of
depression are interpersonal and cognitive/behavioral therapies. Interpersonal therapists focus
on the patient's disturbed personal relationships that both cause and exacerbate (or increase)
the depression. Cognitive/behavioral therapists help patients change the negative styles of
thinking and behaving often associated with depression.
Psychodynamic
therapies, which are sometimes used to treat depressed persons, focus on resolving
the patient's conflicted feelings. These therapies are often reserved until the depressive
symptoms are significantly improved. In general, severe depressive illnesses, particularly those
that are recurrent, will require medication (or ECT under special conditions) along with, or
preceding, psychotherapy for the best outcome.
HOW TO HELP YOURSELF IF YOU ARE DEPRESSED
Depressive
disorders make one feel exhausted, worthless, helpless, and hopeless. Such negative
thoughts and feelings make some people feel like giving up. It is important to realize that
these negative views are part of the depression and typically do not accurately reflect the
actual circumstances. Negative thinking fades as treatment begins to take effect. In the
meantime:
- Set realistic goals in light of the depression and assume a reasonable amount of
responsibility.
- Break large tasks into small ones, set some priorities, and do what you can as you can.
- Try to be with other people and to confide in someone; it is usually better than being alone
and secretive.
- Participate in activities that may make you feel better.
- Mild exercise, going to a movie, a ballgame, or participating in religious, social, or other
activities may help.
- Expect your mood to improve gradually, not immediately. Feeling better takes time.
- It is advisable to postpone important decisions until the depression has lifted. Before
deciding to make a significant transition - change jobs, get married or divorced-discuss it with
others who know you well and have a more objective view of your situation.
- People rarely "snap out of" a depression. But they can feel a little better day-by-day.
- Remember, positive thinking will replace the negative thinking that is part of the
depression and will disappear as your depression responds to treatment.
- Let your family and friends help you.
HOW FAMILY AND FRIENDS CAN HELP THE DEPRESSED PERSON
The
most important thing anyone can do for the depressed person is to help him or her get an
appropriate diagnosis and treatment. This may involve encouraging the individual to stay with
treatment until symptoms begin to abate (several weeks), or to seek different treatment if no
improvement occurs. On occasion, it may require making an appointment and accompanying the
depressed person to the doctor. It may also mean monitoring whether the depressed person
is taking medication. The depressed person should be encouraged to obey the doctor's orders
about the use of alcoholic products while on medication. The second most important thing is to
offer emotional support. This involves understanding, patience, affection, and encouragement.
Engage the depressed person in conversation and listen carefully. Do not disparage feelings
expressed, but point out realities and offer hope. Do not ignore remarks about suicide. Report
them to the depressed person's therapist. Invite the depressed person for walks, outings, to the
movies, and other activities. Be gently insistent if your invitation is refused. Encourage
participation in some activities that once gave pleasure, such as hobbies, sports, religious or
cultural activities, but do not push the depressed person to undertake too much too soon. The
depressed person needs diversion and company, but too many demands can increase feelings of
failure.
Do
not accuse the depressed person of faking illness or of laziness, or expect him or her "to
snap out of it." Eventually, with treatment, most people do get better. Keep that in mind, and
keep reassuring the depressed person that, with time and help, he or she will feel better.
WHERE TO GET HELP
If
unsure where to go for help, check the Yellow Pages under "mental health," "health," "social
services," "suicide prevention," "crisis intervention services," "hotlines," "hospitals," or
"physicians" for phone numbers and addresses. In times of crisis, the emergency room doctor at a
hospital may be able to provide temporary help for an emotional problem, and will be able to
tell you where and how to get further help.
Listed
below are the types of people and places that will make a referral to, or provide,
diagnostic and treatment services.
- Family doctors
- Mental health specialists, such as psychiatrists, psychologists, social workers, or mental
health counselors
;
- Health maintenance organizations
- Community mental health centers
- Hospital psychiatry departments and outpatient clinics
- University - or medical school-affiliated programs
- State hospital outpatient clinics
- Family service, social agencies, or clergy
- Private clinics and facilities
- Employee assistance programs
- Local medical and/or psychiatric societies
