Depression is one of the most common mental health disorders in the world impacting over 300 million people worldwide (that's about the population of the United States of America!), and while 3-5% of adults in the US suffer from depression at any given time, many people may not know the signs and symptoms of clinical depression. It's also important to note that depression is the leading cause of disability worldwide. #depression #symptoms #mentalhealth #mentalhealthblog
|Depression is one of the most common mental health disorders in the world impacting over 300 million people worldwide (that's about the population of the United States of America!), and while 3-5% of adults in the US suffer from depression at any given time, many people may not know the signs and symptoms of clinical depression. It's also important to note that depression is the leading cause of disability worldwide.
​In this third article in a series focusing on depression, we will explore both the symptoms and causes of depression. Other posts from this series include:

Symptoms

Each diagnosis of depression will have a different set of symptoms, and a person will experience a diagnosis of depression that is unique to them. However, most individuals experience symptoms in four main areas: physical, emotional, behavioural, and with their thoughts. ​Some of the common symptoms in each area include:
Physical
  • aches & pains with the absence of physical exercise
  • headaches
  • loss or change of appetite/diet
  • significant weight loss/gain
  • sleeping issues
  • increase in physical ailments & feeling tired
  • digestion problems

Emotional
  • irritable, frustrated, angered easily
  • overwhelmed, indecisive
  • feelings of guilt or disappointment
  • lacking in confidence
  • despair, overwhelming sadness
  • hopelessness
  • extreme sadness & unhappiness

Behavioural
  • reckless
  • isolation, withdrawal from friends/family
  • unmotivated, unfocused
  • loss of interest in usual & enjoyable activities
  • reliance on substances
  • self-harm/suicide attempts

Thoughts
  • "I'm a failure"
  • "I'm worthless"
  • negative thoughts outweigh positive thoughts
  • catastrophizing (thinking the worst will happen)
  • suicidal thoughts/ideation

If you or someone you know is experiencing symptoms that could be associated with depression, reach out for more help from a doctor or mental health professional for proper diagnosis and support.

Causes

The cause of a diagnosis of clinical depression may overlap in three areas: biological, psychological and environmental. Although it can be helpful to read information (like this blog post) or take online tests to find out if the symptoms and concerns you're experiencing may relate to a diagnosis of depression, it's important to have an assessment administered by a doctor or mental health professional and receive an official diagnosis and to discuss treatment options.

If you are concerned about yourself or someone else, grab a pen and paper and write down any of the symptoms listed earlier that you or your loved one has been experiencing for more than two weeks and for most days. Also write down any possible causes from the following list, and bring your concerns with you to your next doctors appointment.

Biological
  • family history, genetic link to depression
  • imbalance of neurotransmitters serotonin and norepinephrine
  • side-effect of medication
  • women have increased risk of developing depression (biology, hormones)

Psychological
  • ​experiences of trauma
  • personality traits (perfectionists, low self-esteem, worriers, self-critical)

Environmental
  • ​grief and loss (death, job loss, retirement)
  • social isolation
  • relationship conflict
  • health issues/chronic illness
  • high levels of stress over prolonged periods
  • experiences of abuse
  • drug & alcohol use

Love this post because depression and anxiety are so common. That anxiety eworkbook is an amazing idea, too! Sometimes I struggle with my anxiety and I really have to fight myself.

Great post.

This is such a great resource. So many times individuals with depression may be unaware of what is causing their symptoms because they are not ones that are commonly thought of as being "depression" related. Thank you for taking the time to provide such a thorough guide and great printables!

So true, Ghastly Girl! I really do feel like 'knowledge is power' and in the case of mental health issues, it can really empower someone to make changes for the better if they know more about what could be happening for them. Thanks so much for your comment!
