Understanding depression
At this stage of our lives, we may also inevitably
experience some form of loss, for example, loss of health, spouse, family
members, or loss of income and independence. Some of these events may cause
us to feel sad or tired every now and then.
Having such feelings of sadness once in a while is a normal
experience, but if our mood is low over an extended period, we could be
suffering from depression.
What is depression?
Common misconceptions:
Some common depressive disorders include:
Major depression
Major depression is also known as major
depressive disorder, classic depression, or unipolar
depression.
People with major
depression experience sadness to a degree that it
affects functioning.
Persistent depressive disorder (Dysthymia)
Dysthymia or persistent depressive
disorder is a milder form of major depression that
lasts for two years or more.
Although persistent depressive disorder may
not be as intense as major depression, it can still
strain relationships and make daily tasks
difficult.
Causes
Depression is caused by a combination of biological, psychological, and environmental factors.
Biological
Biological causes refer to some
illnesses that we might face as we age.
For example, there are some conditions that
might increase the risk of depression, such as
cancer, stroke, arthritis, or heart disease.
Biological
Hereditary/genetic
factors
Depression can run in families, which
could be a sign that it may be inherited and be due
to family genes.
Hence, some may be born with a higher risk of
developing depression. But having a relative with
depression does not necessarily mean someone is
vulnerable to depression.
Biological
Chemical imbalance
Another possible cause of depression is
a chemical imbalance in the brain which affects our
moods.
Hormones that are out of balance can also put
us at a higher risk of depression.
Environmental
Stressful or traumatic events can cause
us to suffer from depression. This includes
relationship problems, worries over finances, loss
of employment, or grief from the death of a loved
one.
Social circumstances also play a part. If we
have lost a spouse, are living alone, feel lonely,
and have few or no friends, then we may be more at
risk of depression.
Psychological
Psychological causes may also play a
part in depression because of an individual’s
biological factors and early life experiences.
People who are perfectionists, easily affected
by criticism, and prone to anxiety may be more
likely to suffer from depression.
Signs and symptoms
A person who experiences five or more of these symptoms for more than two weeks may have a depressive illness.

The signs and symptoms can be managed with early treatment.
The following depressive disorder also has its individual symptoms:
Symptoms of Dysthymia occur for at least two years. They include having a depressed mood and at least two of these symptoms:
Low self-esteem
Having too much or
too little sleep
Feelings of hopelessness
Low energy or fatigue
Poor appetite or overeating
Poor concentration or
difficulty
making decisions
These signs and symptoms are typically severe enough that
they affect day-to-day functioning.
Early treatment from a healthcare professional
helps to manage the signs and symptoms better.
Diagnosis
To diagnose depression, a healthcare professional would conduct a
detailed clinical interview in which he/she would ask about the individual’s
past medical and psychiatric history, family history, current symptoms, and the
impact on his/her functioning.
With the patient’s permission, the healthcare professional may also
request to speak with a family member to gather more information. A standardised
questionnaire, physical examination, and blood tests may be carried out to check
whether depression is present, and how serious
it is.
Treatment
Depression can be treated. When depression is
recognised and treated, a person’s quality of life can be greatly improved.
Treatment may consist of drug (antidepressant medication) and/or non-drug
therapy. Often, a combination of both medication and psychotherapy is used. Patients
may also be taught effective ways to deal with life stresses.
Medication
Medications like
antidepressants have mood-altering properties that
aim to normalise the biochemical imbalances in the
brain.
Medicine is prescribed based on the
individual’s needs. There is no ‘one size fits all’
antidepressant. Some people respond better to one
medicine than another.
With antidepressants,
improvement does not usually show immediately. It
takes about one to three weeks before changes
happen, with some symptoms improving earlier in
treatment than others. For example, energy levels
may improve before feeling a lift in
mood.
To give the medication time to work, it should
be continued for at least 6 months (or longer) after
symptoms are less severe or no longer affecting
day-to-day function.
Continuing or stopping
medication must be advised by a healthcare
professional. For those with several bouts of
depression, long-term treatment may be necessary to
prevent further depressive episodes.
It is important to know that medication alone
may not completely cure depression. However, to help
in recovery, it is effective in treating its
symptoms together with psychotherapy.
Non-drug therapy
Psychotherapy
Psychotherapy involves talking
things through with a healthcare professional.
Talking to someone who can really listen
and understand without passing judgement can be
a great relief, helping in the solving of
problems and the coping of life’s stressors.
Cognitive behavioural therapy (CBT)
Cognitive behavioural therapy (CBT)
is a form of psychotherapy found to be effective
in treating depression.
It helps in recognising and changing
negative thinking and behavioural patterns.
Electro-convulsive therapy (ECT)
Electro-convulsive therapy (ECT)
involves the use of electric current and is only
prescribed to those with severe depression who
have not responded to treatment or are highly
suicidal.
It involves passing a very small electric
current through the brain. The procedure is
carried out under general anaesthesia, taking
just a few minutes, while the patient is asleep.
Learn to better manage depression with these tips:
Support networks
Support groups offer the company of people
in similar situations, where participants hear
first-hand stories of how others cope with depression. A
support system can also be made up of people we trust,
friends, parents, relatives or colleagues that will
support us in times of need.
Reaching
out to connect and share our thoughts and
feelings can help us feel understood, explore new
perspectives, and find different ways to resolve our
difficulties.
Exercise
Exercise not only improves our health but releases endorphins (‘feel good’ hormones) that can elevate our mood. Check out these exercise ideas to stay active.
Learn relaxation audio exercises and guided imagery
-
Deep breathing exercises
Pick up deep breathing exercises as a method of relaxation.
-
Progressive muscle relaxation
Practise progressive muscle relaxation where we tense a group of muscles as we breathe in and relax them as we breathe out.
-
Guided imagery
Use guided imagery where, for example, we imagine ourselves at the beach feeling the warm breeze on our skin.
-
Mindfulness
Consider mindfulness meditation where we train our mind
to pay attention to the present moment without judging
our experiences.
Practise good sleep hygiene
Hygiene refers to conditions or practices
that help maintain health and prevent disease. Poor
sleep hygiene has been found to worsen symptoms of
depression, such as poor sleeping habits, which could
make getting quality sleep harder to achieve.
Learn how to adopt practical sleep
tips for a good night’s rest.
Manage unhelpful thoughts
Sometimes, unhelpful thinking patterns may
make a negative situation appear much worse than it
actually is. For example, we may overgeneralise and
think, “Things will always be bad and will never change”.
When we have such negative thoughts, we can use My
Positivity Guide to reframe such thoughts by
focusing on the good things around us.
Set realistic goals
Setting and accomplishing goals can be an
overwhelming task when one has depression.
Use the SMART goal framework: Specific,
Measurable, Achievable, Realistic, Timely to set
reasonable and achievable goals.
Break down tasks into smaller chunks and affirm
ourselves regularly.
Refrain from drinking
Avoid drowning our sorrows in alcohol as it depresses mood. It may give immediate relief, but it is only temporary.
Depression self-assessment
tool
Depression affects the body, mood, and
thoughts to a point of dysfunction, impacting an individual’s ability to
function at work, at school, and at home.
The Patient Health Questionnaire (PHQ-9) is a set of 9 questions
that those aged 12 and above can use to assess if they
might be suffering from depression. It helps one take stock of where
they are at, so they can make a plan to feel better soon.
Please note this is a self-assessment and not a medical
diagnosis.
