Different Types of Depression

Depression affects millions of Americans. In fact, it’s one of the most common mental health conditions we treat at our Vancouver, WA practice. There are several major depression types, each with its own characteristics and challenges.

So if you’ve been feeling persistently sad, hopeless, or disconnected from life, you’re not alone. And more importantly, there is help available.

You might wonder if what you’re experiencing is “real” depression or just a rough patch. Or you may feel confused about why you can’t simply “snap out of it.” These are concerns we hear every day, and we want you to know that your feelings are valid.

Our goal at Strong Mind Psychiatry is to help you recognize the signs so you can take the first step toward feeling like yourself again.

Main Types of Depression

Major Depressive Disorder (MDD)

Often called major depression, MDD is perhaps the most well-known form of depression. This type of depression involves persistent feelings of sadness, hopelessness, and a loss of interest in activities you once enjoyed.

What makes major depression different from ordinary sadness is its severity and duration. These symptoms persist for at least two weeks and significantly interfere with daily life. Going to work, maintaining relationships, and taking care of basic needs can all become extremely difficult.

Persistent Depressive Disorder (PDD) or Dysthymia

PDD is a long-term form of depression. Previously known as dysthymia, this condition involves a chronically depressed mood that lasts for at least two years in adults.

While the symptoms may not be as intense as major depression, the ongoing nature of PDD can be equally challenging. The reality is that chronic low-grade depression is not something you have to accept as your baseline.

Bipolar Depression

Bipolar depression is a part of bipolar disorder, sometimes called manic-depressive illness. This condition involves cycles of depression alternating with periods of elevated mood called mania or hypomania. During depressive episodes, a person with bipolar disorder experiences symptoms similar to major depression. 

Bipolar depression requires different treatment approaches than other types of depression. Standard antidepressants alone can sometimes trigger manic episodes in people with bipolar disorder.

Seasonal Affective Disorder (SAD)

SAD is a type of depression that follows a seasonal pattern, typically beginning in late fall and continuing throughout winter. It’s particularly relevant for those of us living in the Pacific Northwest.

As the days grow shorter and we receive less natural sunlight, some people experience significant shifts in their mood and energy levels.

Postpartum Depression

While many new mothers experience the ‘baby blues,’ which involve mood swings and crying spells that resolve within a couple of weeks, postpartum depression is more severe and longer-lasting.

Significant hormonal changes occur after childbirth, and some mothers are more vulnerable to these shifts.

Premenstrual Dysphoric Disorder (PMDD)

PMDD is a severe form of premenstrual syndrome that causes significant depression, irritability, and tension before menstruation.

While many women experience some mood changes before their period, PMDD symptoms are much more intense and can seriously disrupt daily life. If monthly mood changes are significantly affecting your quality of life, you don’t have to simply endure them.

Disruptive Mood Dysregulation Disorder (DMDD)

DMDD is primarily diagnosed in children and adolescents. It involves severe and recurrent temper outbursts that are out of proportion to the situation. Between outbursts, the child’s mood is persistently irritable or angry most of the day, nearly every day.

This diagnosis was developed to more accurately describe children who were previously being diagnosed with bipolar disorder, but didn’t quite fit that profile.

What Causes Depression?

Depression is not a personal weakness or something you can simply will away. It’s a complex condition with multiple contributing factors:

Brain Changes

Depression involves changes in brain chemistry and function. Neurotransmitters, which are chemical messengers in the brain, play a significant role in regulating mood. Imbalances in neurotransmitters like serotonin, norepinephrine, and dopamine are associated with depression.

Brain imaging studies have also shown structural differences in the brains of people with depression. Certain areas of the brain involved in mood regulation may be smaller or function differently.

Genetics

Depression tends to run in families. If you have a parent or sibling with depression, you’re at higher risk of developing the condition yourself.

However, genetics alone don’t determine whether you’ll become depressed. They simply increase vulnerability.

Life Experiences

Stressful or traumatic life experiences can trigger depression, especially in people who are already vulnerable.

Childhood trauma, abuse, loss of a loved one, relationship problems, financial difficulties, and major life transitions can all contribute to the development of depression.

Overall Health

Physical health and mental health are closely connected. Certain medical conditions, including thyroid disorders, chronic pain, heart disease, and diabetes, are associated with higher rates of depression.

Sleep problems, lack of physical activity, poor nutrition, and substance use can all affect mood. Some medications can also contribute to depressive symptoms.

Signs to Watch For

While symptoms vary depending on the type of depression, there are some common signs that indicate professional evaluation may be needed:

• Persistent sadness that doesn’t lift. You might feel empty, hopeless, or like nothing matters anymore.
• Loss of interest in activities you used to enjoy. You might also withdraw from friends and family, preferring to be alone.
• Changes in sleep and appetite. You might sleep much more than usual or struggle with insomnia. Some people lose their appetite and lose weight, while others eat more and gain weight.
• Fatigue and low energy that make even simple tasks feel overwhelming. You might feel like you’re moving through molasses.
• Difficulty concentrating or making decisions. Reading a book, following a conversation, or completing tasks at work becomes challenging.
• Feelings of worthlessness and excessive guilt. When negative thoughts about yourself become relentless.

Treatment Options for Depression

• Medication: Antidepressant medications can be highly effective for many forms of depression. For bipolar depression, mood stabilizers are typically used instead of (or in addition to) antidepressants.
• Lifestyle Modifications: Healthy lifestyle habits support mental health and can enhance the effectiveness of other treatments. While these changes alone may not cure depression, they create a foundation of recovery.
• Advanced Treatments: For treatment-resistant depression, additional options exist. Transcranial magnetic stimulation (TMS) uses magnetic fields to stimulate nerve cells in the brain, and Electroconvulsive therapy (ECT) is a safe and effective option for severe depression.
• Psychotherapy: Also called talk therapy, psychotherapy provides a safe space to explore the factors contributing to your depression and develop coping strategies.

Tips for Coping With Depression

While professional treatment is essential for clinical depression, there are also strategies you can use to support your recovery and manage symptoms day to day:

• Maintain structure in your daily life to provide a sense of normalcy and purpose.
• Stay connected with others, even when you want to withdraw. It’ll help combat the isolation that depression creates.
• Avoid alcohol and drugs. While substances might provide temporary relief, they often make depression worse in the long run.
• Engage in activities that have brought you joy in the past even if they don’t feel appealing right now.
• Be patient with yourself, as recovery from depression takes time and progress isn’t always linear.

When to Speak With a Professional

You should consider speaking with a mental health professional if your symptoms have lasted more than two weeks. If depression is interfering with your ability to take care of yourself, maintain relationships, or work, professional help is warranted.

Many people minimize their symptoms or convince themselves they’re “not bad enough” to warrant professional attention. We at Strong Mind Psychiatry want to challenge that thinking.

If you’re having thoughts of suicide or self-harm, please reach out for help right away. Contact the Suicide and Crisis Lifeline by calling or texting 988. If you’re in immediate danger, call 911 or go to your nearest emergency room.

Strong Mind Psychiatry Can Help

Reaching out for help isn’t easy. Depression often tells you that nothing will help or that you don’t deserve to feel better. Those thoughts are symptoms of the illness, not reality. Effective treatment exists, and you deserve to experience it.

At our Vancouver, WA practice, we understand the different types of depression and how to treat them effectively. We take the time to thoroughly evaluate each patient for accurate diagnosis and personalized treatment planning.

If you’re struggling with any form of depression, we encourage you to take the next step. Contact our office today to schedule an evaluation. We offer in-person and virtual appointments.
