4.5.6. Depressive Disorders

One of the most widely prevalent and recognized of all mental disorders is depression. Depression covers a variety of negative moods and behavioural changes. Depression can refer to a symptom or a disorder. In day-to-day life, we often use the term depression to refer to normal feelings after a significant loss, such as the break-up of a relationship, or the failure to attain a significant goal.

Depression is a mental health condition that can manifest in various forms, affecting how a person feels, thinks, and behaves. It is common to associate feelings of sadness with depression, particularly after going through a tough time, such as a breakup or failing at something important like a job or an exam. However, depression is not just a brief bout of sadness; it can last for weeks, months, or even longer. Major depressive disorder, specifically, is defined as a prolonged period of feeling sad or losing interest in activities that one previously found enjoyable.

Imagine a time when you felt down after not making the sports team you wanted to join. While that sadness might have lifted after some time and with support from friends, a person with major depression may feel that sadness persistently, like carrying a heavy backpack every day. No matter what they do, that weight doesn’t seem to lessen.

Major depressive disorder is defined as a period of depressed mood and/or loss of interest or pleasure in most activities, together with other symptoms which may include change in body weight, constant sleep problems, tiredness, inability to think clearly, agitation, greatly slowed behaviour, and thoughts of death and suicide.

Symptoms of major depressive disorder can vary but tend to cluster around emotional, physical, and cognitive experiences. Common emotional symptoms include persistent sadness and loss of enjoyment in activities that once brought happiness. Physical symptoms can include changes in appetite and sleep patterns, where someone might eat more or less than usual, or experience insomnia or oversleeping. Cognitive symptoms might manifest as trouble concentrating or making decisions, and in severe cases, thoughts about self-harm or suicide might arise.

Think of someone you know who was incredibly lively and active and suddenly seemed to withdraw from activities and friends. They might not want to play sports anymore, might stop attending family gatherings, or could appear tired all the time despite having enough sleep. This can be likened to a favorite movie that suddenly stops playing halfway through; the story feels incomplete and troubling because something is wrong.

Genetic make-up, or heredity is an important risk factor for major depression and other depressive disorders. Age is also a risk factor. For instance, women are particularly at risk during young adulthood, while for men the risk is highest in early middle age. Previous suicidal attempts are the strongest risk factors.

Various factors can increase the likelihood of someone developing depression. Genetics can play a significant role, as the disorder can run in families, suggesting a hereditary component. Age also affects the risk, with different time periods in life presenting unique pressures that can lead to depression. Women are statistically more prone to experience depression earlier in life due to societal and hormonal factors, whereas men often see higher rates of depression as they reach middle age. Additionally, a history of suicidal behavior can be an alarming warning signal indicating higher risks for future depressive episodes.

Imagine your family's history; if many people in your family have had struggles with depression, that might feel like an inherited concern. Think of it like having a family tree where certain diseases seem to intertwine, showing branches that need nurturing to prevent further decline. Similarly, societal pressures and personal experiences can pile on stresses, making certain ages particularly prone to feelings of despair.

Bipolar I disorder involves both mania and depression, which are alternately present and sometimes interrupted by periods of normal mood. Manic episodes rarely appear by themselves; they usually alternate with depression.

Bipolar disorder is a condition characterized by extreme mood swings. In Bipolar I disorder, individuals undergo episodes of mania, which can manifest as abnormally elevated mood, energy, or irritability, followed by depressive episodes where they feel severely low. During manic phases, a person may feel invincible, take risks without thinking, and have racing thoughts, whereas during depressive phases, they may struggle to get out of bed or feel hopeless. The alternating nature of these episodes can create havoc in relationships and day-to-day functioning.

Think of a rollercoaster ride where one minute you are at the top of a hill, feeling exhilarated and ready to face the world, while on the next dip, you feel like you are plummeting into darkness. That fluctuation can be dizzying and exhausting, making it difficult for friends and family to keep up with your changing moods.

Often, suicidal behaviour indicates difficulties in problem-solving, stress management, and emotional expression. Suicidal thoughts lead to action only when those thoughts feel like the only escape from distress.

Suicidal thoughts can arise as a dark response to intense emotional pain. When someone feels trapped by their circumstances—unable to see a way out—these thoughts may become more pronounced. It's crucial for individuals to recognize that help is available and that acting on these thoughts is not the only solution. Communities, mental health initiatives, and open conversations about feelings play an essential role in prevention, making it key to address mental health stigma and provide support.

Consider someone trying to navigate through a dense forest during a storm. They might feel lost and overwhelmed, thinking there is no way out. However, if they are able to call for help or follow a guiding light out of the chaos, they can find their way back to safety. In the same way, talking about mental struggles is vital; it can help bring clarity and hope amidst life's storms.
