Understanding depression
As a youth or young adult, we may be experiencing some
changes or transitions in our lives, such as advancing our studies,
searching for job opportunities, stepping into the workforce, or forming new
relationships.
Some of these events or transitions may cause us to feel sad or tired
every now and then. The persistent low mood and lack of interest in
enjoyable activities may actually be symptoms of 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 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.
Premenstrual dysphoric disorder
Premenstrual dysphoric disorder is a severe form of premenstrual syndrome (PMS). Sadness and other depressive symptoms arise due to hormonal fluctuations associated with the menstrual cycle. These symptoms can get in the way of day-to-day functioning.
Disruptive Mood Dysregulation Disorder (DMDD)
Disruptive Mood Dysregulation Disorder (DMDD) is a condition that affects children and adolescents. Intense irritability and frequent temper outbursts are key symptoms. These behaviors go beyond typical moodiness and can interfere with daily life at home, school, and in social settings.
Causes
Depression is caused by a combination of biological, psychological, and environmental factors.
Biological
Hereditary/genetic
factors
Depression can run in families,
indicating hereditary or genetic factors. 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 one’s moods. Hormonal imbalances can also make someone vulnerable to depression.
Biological
Existing conditions
Some conditions may also increase the risk of depression, e,g. cancer, stroke, arthritis, or heart disease.
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.
Environmental
Stressful or traumatic events can cause
people to suffer from depression. Some examples of
such events include experiencing stress from school
or work, relationship problems or conflicts with
family.
Social circumstances may also make us more
vulnerable to depression, affecting those who feel
lonely, or suffer from a chronic illness.
One social factor is social media. The use of
social media has also been linked to depression when
used in an unhealthy manner and when it exposes us
to unrealistic comparisons.

pitfalls of cyberspace while enjoying online
activities is important. Find out more about cyber

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 the following 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
Symptoms of PMDD appear most of the time before one's period. They often begin in the week or two before menstruation and start to ease up a few days after the period begins. To meet the diagnosis for PMDD, at least five symptoms must be present, and it should include one or more from each of the following groups:
Group A
(Mood related symptoms)
- Sadness and despair
- Irritability and anger
- Anxiety
- Extreme mood swings
Group B
(Physical/behavioural symptoms)
- Food cravings or binge eating
- Feeling overwhelmed
- Cramps, bloating, breast tenderness, joint and muscle pain
- Decreased interest in usual activities
- Difficulty in concentrating
- Low energy or fatigue
- Having too much or too little sleep
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 consent, 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 administered to
assess for the presence and severity of depression.
Treatment
Depression is treatable. 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
seek 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 occur,
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 vital to know that medication alone may
not completely cure depression. However, to aid 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 listen and
understand without passing judgement can be a
tremendous 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 fellowship where
participants learn first-hand accounts 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 about 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 a group of muscles is tensed as we breathe in and relaxed as we breathe out.
-
Guided imagery
Use guided imagery such as imagining ourselves at the beach, feeling the warm breeze on our skin.
-
Mindfulness
Consider mindfulness where we train our mind
to pay attention to the present moment without judging
our experiences.
Practise good sleep hygiene
Poor sleep hygiene has been found to worsen
depressive symptoms such as poor sleeping habits, making
it a vicious cycle.
Learn how to adopt practical sleep
tips for a good night’s rest.
Manage unhelpful thoughts
Sometimes, unhelpful thinking patterns may
make a bad situation appear much worse than it actually
is. For example, we may overgeneralise and think, “I
have failed once, I will fail again for sure”.
Identify such negative thoughts to manage them
more positively by using the My
Positivity Guide. Reframe them and focus on the
things we love.
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.
