Effective treatment can help shorten the length of a depressive
episode, reduce the severity and prevent long-term problems such as
social phobias and poor self-esteem.
Most individuals
suffering from depression are successfully treated by their family
doctor. A smaller number attend a psychiatrist and a few people with
more severe forms of depression may require treatment in hospital.
Treatment may
involve psychotherapy, drug therapy or a combination of both,
depending on the cause, type and severity of the illness. In certain
cases electroconvulsive therapy (ECT) may be necessary.
Psychotherapy involves talking to a
therapist about day-to-day relationships (interpersonal
psychotherapy); how to change a negative way of thinking into
positive thinking (cognitive psychotherapy) and how to change a type
of behaviour (behavioural therapy). A diary may be kept to record
sleep and mood patterns and to chart appetite and concentration
difficulties.
During a
depressive episode, it is believed that the levels of certain
chemicals in the brain called neurotransmitters (noradrenaline and
serotonin) are reduced. Some antidepressants used in the
treatment of depression act to combat this reduction in
neurotransmitters.There are three main groups of anti-dpressants:
tricyclic antidepressants (TCADs); selective serotonin reuptake
inhibitors (SSRIs) and monoamine oxidase inhibitors (MAOIs). Lithium,
which is more commonly used for the treatment of maia may be used to
treat severe and recurrent depression. It is important to note that
all of these drugs have side effects, which you should discuss with
your doctor.
Drug treatment can
take up to three to four weeks before any effects are felt and is
normally prescribed for six to nine months. However, it may be
continued for a further six months after the symptoms of depression
have been resolved to prevent the depression recurring. If
depression does return it is important to speak to your GP as a
longer duration of therapy may be considered.
ECT
involves delivering an electrical impulse to the brain through
electrodes, which are placed at specific points on the head. It is
given under light anaesthesia. ECT is effective against severe
depression and is useful in people who are unable to continue with
work or social activities, people who have failed to respond to
courses of antidepressants and in those who refuse fluids.
