Depressive Disorder: Understanding Depression and Its Impact on Daily Functioning

Overview:

Depressive disorder, which is commonly known as depression, is a widespread mental health condition that impacts millions of individuals globally. The condition is marked by a continuous sense of melancholy, lack of enthusiasm, and a range of emotional and physical difficulties [1][3]. Depression is not just another emotion or a response to common life occurrences. Indeed, it is a mood disorder that has a significant impact on an individual’s emotions, thoughts, and actions [1].

Depression is often described as living in a black hole or having a feeling of impending doom. Some people feel lifeless, empty, and apathetic, while others might feel intensely sad, tearful, and overwhelmed by despair. It can also manifest physically, causing chronic pain or other physical problems that do not respond to treatment.

The exact cause of depression is not known, but it is likely due to a combination of genetic, biological, environmental, and psychological factors. Depression can occur at any age, but often begins in adulthood. It is much more common in women, though men can also suffer from depression.

Depression typically involves a range of symptoms. Some of the most common symptoms of depression include:

Persistent feelings of sadness, tearfulness, emptiness or hopelessness
Loss of interest or pleasure in most or all normal activities
Sleep disturbances, including insomnia or sleeping too much
Tiredness and lack of energy, so that even small tasks take extra effort
Changes in appetite — often reduced appetite and weight loss, but also overeating and weight gain in some people
Anxiety, agitation, or restlessness
Slowed thinking, speaking, or body movements
Feelings of worthlessness or guilt, fixating on past failures or blaming oneself for things that are not one’s responsibility
Trouble thinking, concentrating, making decisions, and remembering things
Frequent thoughts of death, suicidal thoughts, suicide attempts, or suicide
Unexplained physical problems, such as back pain or headaches

To be diagnosed with depression, symptoms must be present most of the day, nearly every day for at least two weeks. However, the severity, frequency, and duration of symptoms will vary depending on the individual and their particular illness.

Depression is a chronic illness that usually requires long-term treatment, like diabetes or high blood pressure. But don’t get discouraged. Most people with depression feel better with medication, psychotherapy, or both. Lifestyle changes can also be an essential part of treatment. Regular physical activity and regular sleep can help manage symptoms of depression.

It’s important to remember that if you’re suffering from depression, it’s not a sign of weakness or something you can just “snap out of.” Depression is a medical condition that requires treatment, and there’s nothing to be ashamed of. With the right treatment plan, most people with depression can achieve significant improvement and enjoy a better quality of life.

Types of Depression:

Depression encompasses various forms, including major depressive disorder and persistent depressive disorder (dysthymia) [2]. Major depressive disorder is characterized by symptoms of depression that persist for at least two weeks and interfere with daily functioning, such as work, sleep, study, and eating [2]. On the other hand, persistent depressive disorder involves milder symptoms of depression that last for an extended period, typically at least two years [2]. Both forms of depression can significantly impact an individual’s quality of life, Mental Well-being and require professional attention and treatment.

Depression is a complex condition that can take several forms. Here are some of the most common types of depression:

Major Depressive Disorder (MDD): This is what most people think of when they hear “depression.” MDD is characterized by persistent feelings of sadness, loss of interest in activities, changes in appetite, sleep disturbances, and sometimes thoughts of death or suicide. These symptoms must be present for at least two weeks for a diagnosis of MDD.
Persistent Depressive Disorder (Dysthymia): This is a chronic form of depression that lasts for at least two years. While the symptoms may not be as severe as those of MDD, they are persistent and can significantly impact a person’s quality of life.
Postpartum Depression: This type of depression occurs in women after giving birth. It’s characterized by feelings of extreme sadness, anxiety, and exhaustion that can make it difficult for new mothers to complete daily care activities for themselves or for their babies.
Seasonal Affective Disorder (SAD): This is a type of depression that’s related to changes in seasons. SAD begins and ends at about the same times every year. Most people with SAD experience symptoms starting in the fall and continue into the winter months, sapping their energy and making them feel moody.
Bipolar Disorder: While not a type of depression, depression is a significant part of bipolar disorder, which involves periods of extremely low moods that meet the criteria for major depression (called “bipolar depression”) and periods of extremely high moods (called “mania” or “hypomania”).
Premenstrual Dysphoric Disorder (PMDD): This is a severe form of premenstrual syndrome (PMS). It’s characterized by severe depression, irritability, and tension before menstruation.
Atypical Depression: This type of depression includes symptoms that are different than those of typical depression. People with atypical depression may experience a mood lift in response to positive events, significant weight gain or increase in appetite, excessive sleep, a heavy feeling in the arms or legs, and sensitivity to rejection.
Psychotic Depression: This is a type of severe depression that includes some form of psychosis, such as having disturbing false fixed beliefs (delusions) or hearing or seeing upsetting things that others cannot hear or see (hallucinations).

Each type of depression has different symptoms and may require different treatment approaches. It’s important to talk to a healthcare provider for an accurate diagnosis if you’re experiencing symptoms of depression.

Symptoms and Causes:

The core symptoms of depression include a persistent feeling of sadness and a loss of interest or pleasure in activities that were once enjoyed [1][3]. Individuals with depression may experience a range of additional symptoms, such as changes in appetite and weight, sleep disturbances, fatigue, difficulty concentrating, feelings of worthlessness or guilt, and recurrent thoughts of death or suicide [3].

The causes of depression are multifactorial and can vary from person to person. It is believed that a combination of genetic, biological, environmental, and psychological factors contributes to the development of depression [3]. Certain life events, such as trauma, the loss of a loved one, relationship difficulties, or financial problems, can also trigger or exacerbate depressive episodes. Furthermore, imbalances in brain chemicals called neurotransmitters, such as serotonin, norepinephrine, and dopamine, are associated with depression [3].

Depression Symptoms in Different Age Groups:

Depression can affect individuals of all ages, including children, teenagers, and older adults. However, the symptoms may manifest differently depending on the age group [1][3].

In children and teenagers, depression symptoms may include irritability, social withdrawal, changes in appetite and sleep patterns, difficulty concentrating, academic decline, and physical complaints such as headaches or stomachaches [1][3]. It is essential for parents, caregivers, and educators to be vigilant about these signs and seek appropriate professional help to support the mental well-being of young individuals.

In older adults, depression symptoms may sometimes be overlooked or mistaken for normal ageing processes or other health conditions. They may experience persistent sadness, loss of interest in previously enjoyed activities, significant weight loss or gain, memory difficulties, sleep disturbances, and even physical pain that does not respond to treatment [3]. Recognizing and addressing depression in older adults is crucial for their overall well-being and quality of life.

When to Seek Medical Assistance:

If you or someone you know is experiencing symptoms of depression, it is important to seek medical assistance. Depression is a treatable condition, and early intervention can lead to better outcomes. Here are some indicators of when to consider reaching out to a healthcare professional [1][3]:

Products & Services:

Numerous products and services are available to support individuals with depression. These include various forms of therapy, such as cognitive-behavioural therapy (CBT), interpersonal therapy (IPT), and psychodynamic therapy. Medications, such as antidepressants, may also be prescribed in certain cases to help manage symptoms [3]. Additionally, support groups, self-help resources, and online platforms can provide valuable information and assistance.

Research and Education:

Ongoing research plays a vital role in understanding the complexities of depressive disorders and developing innovative treatments. Researchers strive to uncover the underlying causes, identify effective interventions, and reduce the stigma surrounding mental health conditions. Education about depression, its symptoms, and available treatments is also essential in increasing awareness, promoting early detection, and fostering a supportive environment for those affected.
