 Depression

Overview

Depression is a common mental illness that affects millions of people around the world. It’s more than just feeling down or sad, it’s a serious condition with both physical and psychological symptoms. Symptoms of depression can include changes in mood, loss of interest in activities that used to bring pleasure, fatigue, difficulty concentrating, thoughts of suicide and worthlessness, changes in appetite and sleep, and physical aches and pains.

Depression is caused by a combination of psychological, social, and biological factors, including genetics, early life experiences, and medical conditions. Treatment for depression typically combines therapies—such as talk therapy, cognitive-behavioral therapy, interpersonal therapy, or psychodynamic therapy—and medication.

Major depression

Major depression, also called major depressive disorder (MDD), is a serious mental health issue that can lead to a general decline in feelings of well-being, energy, and enthusiasm. It also impairs the ability to work, interact with family and friends, and enjoy life in general. Major depression is characterized by a persistent sad, anxious, or empty mood that lasts for at least two weeks and is accompanied by feeling hopeless, guilty, and worthless. Other physical and psychological symptoms may also be present.

Major depression is a very serious condition that can have several associated complications, including an increased risk for suicide, a decline in overall physical health, and an impaired ability to function in daily life. Treatment for major depression typically includes medication, talk therapy, or a combination of both.

Persistent depressive disorder

Persistent depressive disorder, also known as dysthymia, is a type of chronic depression characterized by a low, persistent, or persistent-relapsing mood for at least two years for adults and one year for children and adolescents. Other associated symptoms of persistent depressive disorder include a loss of interest in normal activities, difficulty sleeping or concentrating, fatigue, changes in appetite, poor self-esteem, and feelings of guilt or hopelessness. 

Persistent depressive disorder can be challenging to diagnose and can lead to a decreased quality of life. It is typically treated with a combination of talk therapy, such as cognitive-behavioral therapy (CBT) and other forms of psychotherapy, along with medication. It is important to note that each person with persistent depressive disorder should receive individualized treatment and support tailored to their own needs.

Perinatal depression

Perinatal depression is a depressive disorder that occurs during pregnancy or in the first 12 months postpartum. It is more than just the “baby blues” and can greatly interfere with a mother's ability to care for herself and her baby. Symptoms may include low mood, lack of energy, loss of motivation, difficulty concentrating, insomnia, and suicidal thoughts. 

Treatment of perinatal depression typically involves support as well as evidence-based psychotherapies such as cognitive-behavioral therapy (CBT) and interpersonal therapy (IPT) and may also involve medications. Self-care is also important, such as maintaining a healthy diet and exercise routine, getting adequate sleep, and talking openly with supportive family members or friends. Support groups and professional counseling can also help women cope with the stress of being a new mother.

Seasonal affective disorder

Seasonal affective disorder (SAD) is a form of depression that is recurrently experienced during the same season every year. It is most commonly experienced during the darker, winter months, though it can occur in the summer as well. Symptoms typically include decreased energy, social withdrawal, sleeping too much, and hopelessness. Other symptoms may include changes in appetite, concentration difficulties, and feelings of worthlessness. 

Treatment of SAD typically involves lifestyle changes, with light therapy being a common choice. Cognitive-behavioral therapy (CBT) is often used to help people identify and modify their negative, mood-influencing thoughts and behaviors. Antidepressant medications may also be prescribed to help affected individuals cope. Self-care strategies can also be an important part of managing SAD, such as regular exercise, minimizing alcohol, and getting proper nutrition and sleep. Psychological or emotional support from family and friends can also be helpful.

 Symptoms of psychosis

Psychotic depression is a severe form of depression that includes symptoms of psychosis. Psychosis is marked by abnormal or delusional thinking and distorted perceptions of reality. Symptoms of psychotic depression can include delusions, hallucinations, disorganized thoughts, speech, behavior, and extreme suicidal ideation. Often, people who experience psychotic depression also experience paranoia, persecutory delusions, and auditory or visual hallucinations. 

Treatment for psychotic depression is similar to other forms of depression, but may include additional interventions like antipsychotic medications and psychological counseling. Other therapies that are commonly used to treat psychotic depression include cognitive-behavioral therapy (CBT), interpersonal therapy (IPT), and dialectical behavior therapy (DBT).

Medications that are typically used to treat psychotic depression include atypical antipsychotics, tricyclic antidepressants, and MAO inhibitors. In addition, psychotherapy and other therapeutic interventions can be important components of the treatment plan. Proper assessment of the patient is essential in order to identify the underlying cause of psychotic depression and the appropriate treatment plan.

Signs and Symptoms

Depression is a mental health disorder often characterized by prolonged and intense feelings of guilt, sadness, hopelessness, worthlessness, and emptiness. Other common signs and symptoms of depression include: 

• Loss of interest in activities previously enjoyed

• Feelings of hopelessness, guilt, shame, or worthlessness

• Changes in appetite (usually weight loss)

• Changes in sleep patterns (like insomnia)
