Depression is a mental health disorder that results in a constant feeling of sorrow and a loss of interest in once-enjoyed activities. It is usually classified in the category of mood disorders. It can affect a person’s thoughts, behavior, feelings, and sense of well-being. 

Depression is a common mental health condition, affecting an estimated 280 million people worldwide. It is more common in women than in men. Depression can occur at any age, but it is most common in adults aged 25–44.

Depression can be mild, moderate, or severe and can last for weeks, months, or even years. Mild or moderate depression is, to some extent, manageable, but severe depression does not usually end well and may take the person down the suicidal trail, also known as major depressive disorder with suicidal thoughts in medical terms. To simplify it for our enlightened readers, it is commonly known as suicidal depression. There are different patterns of depressive episodes, including: 

1. Single episode depressive disorder: It means that this person had a single and only episode of depression, likely to never happen again.

2. Recurrent depressive disorder: It means that this person has previously had repeated depressive episodes, with the minimum number being two.

3. Bipolar disorder: People with bipolar disorder experience alternating periods of depression and mania. During mania, people may feel euphoric, irritable, or have increased energy and activity levels. They may also talk more than usual, have racing thoughts, feel very good about themselves, need less sleep, be easily distracted, or engage in impulsive or reckless behaviors.


The level of suicidal tendencies depends on the presence and severity of depression symptoms. The symptoms, if persisted for more than 2 weeks, are considered an alarming sign. Moreover, if a person shows five or more symptoms, it is advised to discuss them with a nearby clinical psychologist, who might well catch the root cause of the issue and be able to timely counsel them. Some of the generic symptoms are given below:

  • Feeling sad, hopeless, or empty. 
  • Thoughts about dying or suicide
  • Not enjoying things that you used to enjoy.
  • Losing or gaining a significant amount of weight without trying.
  • Having trouble sleeping or sleeping too much.
  • Slow or agitated psychomotor skills (Moving more slowly or more quickly than usual)
  • Feeling tired all the time.
  • Feeling like you are worthless or that you have done something wrong, even if you haven’t.
  • Having trouble thinking clearly or concentrating on tasks.
  • Having thoughts of death or suicide, or making plans to hurt yourself.

How does the brain depression mechanism work inside the brain?

Just to quench your curiosity, the mechanism of depression inside our brain works like so: 

Our brain nerves don’t physically touch each other. Instead, they communicate with each other through chemicals called neurotransmitters. The right amount of these chemicals is needed to pass messages accurately from one nerve to the next. If there’s not enough of a certain neurotransmitter, the message may not be passed correctly, which can lead to depression. Serotonin and norepinephrine are two of the most common neurotransmitters that are out of balance in people with depression. 

A person with depression may have completely different thoughts and feelings during a depressive episode than they do when they are not depressed. Hence, the chemical imbalance leads to different thought patterns than a normal rational man would have. Hence, the chemical imbalance in brain makes them see suicide as their only best option and they forget about consequences.


Suicide is the deliberate act of bringing about one’s own death. It is the tenth most common cause of mortality in the US, making it a critical public health concern. Numerous things, such as mental health issues, substance misuse, and upsetting life events, might lead to suicide. 

Warning signs of suicide include: 

  • Abrupt mood swings from intense sadness/irritability to shared calmness 
  • Changes in behavioral patterns become impulsive.
  • Looking for ways to harm oneself.  
  • Having marks of cuts or bruises on their body 
  • Talking about death directly or indirectly
  • Giving away possessions. 
  • Saying unexpected goodbyes
  • Put an end to life. 


Usually, people around the person who has depression are unaware of the actual hell the depressed person is going through. They are completely unaware and usually show carelessness as to whether the depression can be real or if it can be this severe to lead to ending one’s own life? Or does depression cause suicide? This carelessness and apathy on the part of family members, friends, and partners leads to suicide by the depressed person since they feel lonely.

People with depression may not realize that their depression is treatable and that there are people who can help them. They may feel hopeless, like there is no way out. They may also feel like they are burdening others with their problems. However, it is important to remember that Depression is a serious condition, and it is important to seek help if you are experiencing it. 

Here are reasons and evidence to support the connection between depression and suicide:

1. Hopelessness and Despair:

Persistent feelings of emptiness come from a place of loneliness and despair, simply being without purpose, which occurs due to depression. Hence, leading to suicidal thoughts.

2. Contributing to Impaired Judgment:

Depression interferes with a person’s ability to judge and discern what’s good for them. This usually happens due to an imbalance of chemicals in the brain, which interferes with their ability to think about their past happy moments and about their future when in an episode of depression. Hence, they only see suicide as their best chance at living.

3. Suicidal Ideation: 

Suicidal ideation, which precedes suicide attempts, is highly correlated with depressive symptoms such as feelings of worthlessness, hopelessness, and on-going unhappiness.

4. High Prevalence of Depression Among Suicide Victims:

Numerous studies have shown a strong association between depression and suicide. A significant percentage (50%, according to the WHO) of individuals who die by suicide have a history of depression or other mood disorders.

5. Comorbidity with Other Risk Factors:

Depression commonly co-occurs with other suicide risk factors, such as substance abuse, long-term physical illness, or a traumatic past, which increases the risk.

6. Effectiveness of Treatment:

Evidence shows that when depression is dealt with, suicidal thoughts vanish like they never existed. When psychotherapy, medications, and lifestyle changes are incorporated, it ends depression and ultimately sways suicidal thoughts away.  This suggests a strong connection between depression and suicide.

7. Improved Mental Health Treatment: 

There has been a commensurate decline in suicide rates in areas where mental health treatment and awareness have improved. This suggests that treating depression and other mental health conditions can have a favorable effect on preventing suicide. E.g., in the organized and educated West, suicide rates were significantly declining when people started paying attention to them.

8. Psychological Autopsies:

Psychological autopsies are frequently carried out following a suicide to comprehend the subject’s mental state prior to passing away. Investigations like this frequently turn up evidence of prior untreated or inadequately treated depression, which provides huge evidence on depression and suicide’s interlinkage.


  • A person’s family history of suicide might also persuade them to commit suicide. 
  • Apart from depression, other mental health conditions like bipolar disorder, schizophrenia, and borderline personality disorder can also lead to suicide risk.
  • Throughout life, many significant losses, like relationship crisis, financial issues, unemployment, or family problems, can lead to an increase in suicidal thoughts and behaviors.
  • Substance abuse and addiction can impair judgment and increase impulsivity, making individuals more prone to suicidal actions.
  • Feelings of despair and risk of contributing to suicide can be further exacerbated by chronic physical illnesses, severe pain, or terminal diagnoses. 
  • Impulsive suicidal actions may occur easily when firearms or lethal things are easily accessible to them. 
  • Individuals with a history of suicide attempts before are at a higher risk of future attempts or completing suicide.
  • Suicidal tendencies are more frequent in people with feelings of loneliness, lack of social support, and isolation. 
  • Cultural or religious beliefs that stigmatize mental health issues or suicide can inhibit help-seeking behavior and increase feelings of shame, elevating risk.

Around 800,000 suicides were reported worldwide in 2015, and 78% of all completed suicides worldwide occurred in low- and middle-income countries, according to a study published on Pubmed called Epidemiology of Suicide and the Psychiatric Perspective, which presented real data gathered from various resources on suicide’s causes. Globally, 1.4% of premature deaths are caused by suicide. According to research, depression accounted for 30% of all global mortality from non-natural causes at the start of the twenty-first century.


Suicide is a major symptom of depression as well as its consequence. The statistics given below are evidence of the fact that Depression is the leading cause of suicide. To know more about how many suicides are caused by depression, Secondary research data has also been provided:

  1. According to the World Health Organization, every year, around 700,000 people commit suicide. 
  2. For people aged 15 to 29, suicide is the fourth most common cause of death. 
  3. WHO predicts that by the year 2030, depression will be the leading cause of disability worldwide (World Federation for Mental Health, 2012).
  4. An estimated 3.8% of the population, including 5% of adults (4% of men and 6% of women) and 5.7% of those over 60, experience depression. 
  5. Around 280 million people worldwide suffer from depression.  
  6. Women are around 50% more likely than men to experience depression. More than 10% of pregnant and recently delivered women experience depression globally. 

A survey conducted by the Center for Suicide Prevention in Canada revealed the following statistics:

  1. According to the Canadian Medical Association Journal (2013), 5-8.2% of the population of Canada experiences a major depressive episode in a given year.
  2. The probability of suicide over the course of one’s life is 2.2-15% for those with untreated depression.
  3. Of all suicides, at least 50% involve depression.
  4. The risk of suicide is 25 times higher for people with depression than for the general population (American Association of Suicidology, 2014).
  5. There is evidence that serious depression affects 50–80% of elderly people who commit suicide.
  6. According to the Mood Disorders Society of Canada (2013), just one-third of depressed people seek treatment.

Depression makes a person vulnerable enough and out of their minds to make them see death as their only escape.

Examples of strategies to improve life skills and foster resilience include skill development, mobile apps, and self-help resources.
