Depression
Depression (major depressive disorder) is a
common and serious medical illness that negatively affects how you feel, the way you think and how you act. Fortunately, it is
also treatable. Depression causes feelings of sadness and/or a loss of interest
in activities once enjoyed. It can lead to a variety of emotional and physical
problems and can decrease a person’s ability to function at work and at home.
Causes
The
causes of depression are not fully understood and may not be down to a single
source. Depression is likely to be due to a complex combination of factors that
include:
·
depressed
woman
·
Depression
has a wide range of causes and potential treatments.
·
genetics
·
biological
- changes in neurotransmitter levels
·
environmental
·
psychological
and social (psychosocial)
Symptoms
Although depression may occur only
once during your life, people typically have multiple episodes. During these episodes, symptoms
occur most of the day, nearly every day and may include:
·
Feelings
of sadness, tearfulness, emptiness or hopelessness
·
Angry
outbursts, irritability or frustration, even over small matters
·
Loss
of interest or pleasure in most or all normal activities, such as sex, hobbies
or sports
·
Sleep
disturbances, including insomnia or sleeping too much
·
Tiredness
and lack of energy, so even small tasks take extra effort
·
Reduced
appetite and weight loss or increased cravings for food and weight gain
·
Anxiety,
agitation or restlessness
·
Slowed
thinking, speaking or body movements
·
Feelings
of worthlessness or guilt, fixating on past failures or self-blame
·
Trouble
thinking, concentrating, making decisions and remembering things
·
Frequent
or recurrent thoughts of death, suicidal thoughts, suicide attempts or suicide
·
Unexplained
physical problems, such as back pain or headaches
For
many people with depression, symptoms usually are severe enough to cause
noticeable problems in day-to-day activities, such as work, school, social
activities or relationships with others. Some people may feel generally
miserable or unhappy without really knowing why.
Types
Unipolar
and bipolar depression
If
the predominant feature is a depressed mood, it is called unipolar
depression. However, if it is characterized by both manic and depressive
episodes separated by periods of normal mood, it is referred to as bipolar
disorder (previously called manic depression).
Major depressive
disorder with psychotic features
This
condition is characterized by depression accompanied by psychosis. Psychosis
can involve delusions - false beliefs and detachment from reality, or
hallucinations - sensing things that do not exist.
Postpartum
depression
Women
often experience "baby blues" with a newborn, but postpartum
depression - also known as postnatal depression - is more severe.
Major depressive
disorder with seasonal pattern
Previously
called seasonal affective disorder (SAD), this condition is related to the
reduced daylight of winter - the depression occurs during this season but lifts
for the rest of the year and in response to light therapy.
Risk Factors for Depression
Depression
can affect anyone—even a person who appears to live in relatively ideal
circumstances. Several factors can play a role in depression:
Biochemistry: Differences in certain chemicals
in the brain may contribute to symptoms of depression.
Genetics: Depression can run in families.
For example, if one identical twin has depression, the other has a 70 percent
chance of having the illness sometime in life.
Personality: People with low self-esteem, who
are easily overwhelmed by stress, or who are generally pessimistic appear to be
more likely to experience depression.
Environmental
factors:
Continuous exposure to violence, neglect, abuse or poverty may make some people
more vulnerable to depression.
Complications
Depression
is a serious disorder that can take a terrible toll on you and your family.
Depression often gets worse if it isn't treated, resulting in emotional,
behavioral and health problems that affect every area of your life. Examples of
complications associated with depression include:
·
Excess
weight or obesity, which can lead to heart disease and diabetes
·
Pain
or physical illness
·
Alcohol
or drug misuse
·
Anxiety,
panic disorder or social phobia
·
Family
conflicts, relationship difficulties, and work or school problems
·
Social
isolation
·
Suicidal
feelings, suicide attempts or suicide
·
Self-mutilation,
such as cutting
·
Premature
death from medical conditions
Treatment
Depression is a
treatable mental illness.
There are three components to the management of depression:
Support- Ranging from discussing
practical solutions and contributing stresses, to educating family members.
Psychotherapy- Psychotherapy, or “talk
therapy,” is sometimes used alone for treatment of mild depression; for
moderate to severe depression, psychotherapy is often used in along with
antidepressant medications. Cognitive behavioral therapy (CBT) has been found
to be effective in treating depression. CBT is a form of therapy focused on the
present and problem solving. CBT helps a person to recognize distorted thinking
and then change behaviors and thinking.
Drug treatment- Antidepressants are drugs
available on prescription from a doctor. Drugs come into use for moderate to
severe depression, but are not recommended for children, and will be prescribed
only with caution for adolescents.
Electroconvulsive
Therapy - Electroconvulsive
Therapy (ECT) is a medical treatment most commonly used for patients with severe
major depression or bipolar disorder who have not responded to other
treatments. It involves a brief electrical stimulation of the brain while the
patient is under anesthesia. A patient typically receives ECT two to three
times a week for a total of six to 12 treatments. ECT has been used since the
1940s, and many years of research have led to major improvements. It is usually
managed by a team of trained medical professionals including a psychiatrist, an
anesthesiologist and a nurse or physician assistant.
Medication: Brain chemistry may contribute to
an individual’s depression and may factor into their treatment. For this
reason, antidepressants might be prescribed to help modify one’s brain
chemistry. These medications are not sedatives, “uppers” or tranquilizers. They
are not habit-forming. Generally antidepressant medications have no stimulating
effect on people not experiencing depression.
Prevention
There's
no sure way to prevent depression. However, these strategies may help.
·
Take
steps to control stress, to increase your resilience and boost your
self-esteem.
·
Reach
out to family and friends, especially in times of crisis, to help you weather
rough spells.
·
Get
treatment at the earliest sign of a problem to help prevent depression from
worsening.
·
Consider
getting long-term maintenance treatment to help prevent a relapse of symptoms.
