Depression symptoms can vary from mild to severe and can include:
- Despondent mood or sadness
- Inability to think coherently or concentrate
- Decreased interest or pleasure in activities you once enjoyed
- Difficulty making even simple decisions
- Changes in appetite
- Weight gain or loss unrelated to dieting
- Sleeping too little or sleeping too much
- Fatigue or low energy
- Increase in purposeless physical activity (pacing, handwringing, rocking)
- Slowed movements and speech (observable by others)
- Feelings of worthlessness or guilt
- Suicidal ideation
Symptoms must last at least two weeks for a diagnosis of depression.
The four most common types of depression are: major depression, persistent depressive disorder, bipolar disorder, and seasonal affective disorder.
Major depression is a state where the individual’s mood and demeanour are persistently dark, causing them to lose interest in activities once found pleasurable. Common symptoms are insomnia or excessive sleep, changes in weight unrelated to diet, and feelings of worthlessness or guilt. Often, the individual has thoughts about suicide or death. Most commonly treated with psychotherapy and medication, and in some cases electroconvulsive therapy may be effective.
Persistent depressive disorder refers to a “low” mood that has spanned at least two years, though it may not have been classified as major depression. Many individuals with PDD can carry out their day to day lives, but they experience a persistent, underlying feeling of sadness. They may experience sleep issues, unexplained weight gain or loss, and hopelessness.
Individuals with bipolar disorder—once known as manic-depressive disease—experience periods of depression (lows) as well as periods of high energy or activity (highs). Manic and depressive episodes are at opposite ends of the spectrum. For example, where depression is low self-esteem and energy, manic is grandiose ideas and unnaturally high self-esteem. While being manic is associated with positive feelings, it is still emotion out of balance and often includes self-destructive behaviour leading to depression. Individuals with bipolar disorder can manage their illness with medications that stabilize their moods, and coupled with psychotherapy can lead active, fulfilling lives.
Seasonal affective disorder (SAD) is as its name implies, tied to the change in seasons. It mainly afflicts people as days get shorter in the fall and winter. An individual with SAD experiences changes in mood related to changes in the body’s natural rhythms and the impact of changes in light on chemical messengers like serotonin and melatonin. One of the most effective and least invasive treatments is light therapy, where the individual sits close to an intense light source. Psychotherapy and medication may also be included in the treatment plan.
Depression types unique to women
Women are at higher risk for general depression than their male counterparts. Additionally, women are at risk for two different types of depression influenced by reproductive hormones—perinatal depression and premenstrual dysphoric disorder (PMDD).
Perinatal depression includes both major and minor depressive episodes occurring during pregnancy or in the first 12 months after delivery (commonly referred to as postpartum depression) — one in seven women who give birth experience perinatal depression. Its effects can be devastating for the woman, her infant, and her family. Treatment includes counselling and medication.
PMDD is a severe form of premenstrual syndrome or PMS. PMDD symptoms generally begin shortly after ovulation and end once menstruation begins. Selective serotonin reuptake inhibitors (SSRIs), such as fluoxetine (Prozac) and sertraline (Zoloft), may be effective in reducing symptoms.
The benefits of online therapy may outweigh the face-to-face experience. One person explains: I would rather watch an entire streaming series than see only a few in high definition. In other words, the benefit of online allows me to meet regularly and consistently, at my convenience. In the end it is all about finishing well!
