Understanding Depression
Understanding depression is an important element in the treatment of clinical depression. The Diagnostic and Statistical Manual (DSM-5), the primary resource for psychologists and psychiatrists, makes clear that Depression is not just sadness.
Depression is a clinically significant condition, with biological causes and effects, that can dramatically decrease quality of life, and have significant consequences on anyone suffering from it.
Types of Depression
There are many types of depression, all of which have been researched and defined by psychologists, and described in the DSM-5.
1. Major Depression (or Major Depressive Disorder) is a condition in which you deal with intrusive and distressing symptoms more days than not, for most of the hours in those days. Symptoms include feeling down; no longer taking pleasure in most activities (anhedonia); disturbances in sleep, appetite, and activity level; difficulty concentrating, and thoughts of suicide. Not all symptoms have to be present to meet criteria for Major Depression, and there are different levels of severity. Mild Depression is the least severe, Moderate Depression is more significant, and Severe Depression involves the most acute symptoms, often including suicidal ideation.

Mental Health Professionals and their Roles in treating depression
Depression Treatment: Finding the Right Professional
Finding the right professional to treat your depression can feel daunting, but it does not need to be. The most important elements to look for when finding a therapist include valid licensure or supervision by somebody with a valid license (an absolute must), some demonstration of competence (i.e. look at their education and experience), and a sense that you can feel comfortable with them. Many therapists will provide a free introductory phone call so you can ask some questions and get some sense of who they are, and whether they will be a good fit for you personally. Sometimes you won’t be able to get this clarified until you sit with them for a session or two. If you are somebody who needs a lot of accountability, perhaps you look for a more direct therapist. On the other hand, if you prefer having a lot of space to make your own decisions, you may be looking for a therapist who asks really great questions that help you clarify your own thought processes. It may help to watch this video to get some ideas on how to effectively go through this process.
Medication Options for Treating Depression
There are more and more medication options for treating depression, as evidenced by commercials and ads on TV and the internet. It can be tricky to know which medication options are right for you. As a psychologist, I do not have medical training, and therefore can only give a high-level overview of the types of medication. If you are seeking medication treatment for depression, you will want to schedule an appointment with your general practitioner or a mental health prescriber (i.e. psychiatrist, clinical nurse practitioner, etc.).
1. Selective Serotonin Reuptake Inhibitors (SSRIs) are the most commonly prescribed medication for depression. These include Prozac (fluoxetine), Zoloft (sertraline), Celexa (citalopram) and other names that you may recognize. They work by allowing more serotonin (a “feel-good” chemical) to be present in your brain.

Psychotherapy Approaches in treating Depression
Individual vs. Group Therapy for depression
Group therapy is therapy with one therapist (sometimes two) and several other people who are dealing with (usually) similar issues to yours. Some group therapy is designed to be merely supportive (i.e. a support group), where you listen to each other and provide sympathy and empathy. Other groups are more process-oriented, where the trained group therapist works to help uncover patterns that emerge within the group, generally mirroring issues that likely occur in real life. As these patterns are pointed out, group members work through the issues that are causing them, providing invaluable practice for working through issues with friends and family. Other types of groups can also be helpful, including dialectical behavioral therapy (DBT), specifically designed for skill-building, chemical dependency groups for supporting abstinence or harm-reduction, or others. Group therapy can be quite helpful on its own, or in tandem with individual therapy. In ideal circumstances, your individual and group therapist communicate with each other to help maximize results for their clients.

Lifestyle Changes for Depression Management
- Healthy eating is a powerful way to decrease depression symptoms. Our brains and bodies are inextricably linked, and when one or the other suffers, the other is bound to struggle as well. The better you eat (a balanced diet of lean proteins, tons of fruits and veggies, healthy grains, and minimal healthy fats and sugars), the better your body feels. The better your body feels, the more likely your brain is to respond healthily to stressors. In fact, the National Institute of Health (NIH) has noted that “the most well-established example of mind-body interaction is the link between psychological stress and psychological ill-health.” Simply put, if you feel physically terrible, you are far more likely to struggle with negative emotions.
- Exercise also helps promote positive mental health and reduce mental illness. While the most profound mitigating effect of exercise was found for anxiety, there is a significant positive impact of exercise on symptoms of depression as well. The Mayo Clinic indicates that “working out and other forms of physical activity can ease symptoms of depression and anxiety and make you feel better.” Something as simple as walking for 5-10 minutes a day can make a substantial difference in your psychological wellbeing.
- Getting outside on a regular basis is also a great way to decrease your symptoms of depression. Studies are quite clear in establishing an inverse correlation between exposure to sunlight (even behind cloud cover) and depression. In a meta-analysis of many studies examining this issue, the NIH found that “sunlight provided protection against a wide range of diseases–not only physical disease but mental disorders.” It can be challenging to force yourself outside when you’re depressed, but it is clear that the effort will very likely pay off, either in the short term, the long term, or both.
Implementing Healthy Habits
- Linking: By linking an activity that you really enjoy (e.g. watching your favorite TV show or listening to music) with an activity that is hard to make yourself do (e.g. going for a walk, folding laundry), you can begin to establish a positive association in your brain with the previously undesirable activity.
- Accountability: Many people find that challenging activities are easier to face when they have told somebody they are planning to do it. Or if they plan to do the activity WITH somebody in their lives. Going for a walk is another great example. Suddenly exercise (groan) becomes time with friends (yay!).
- Working downhill: Most of us save the “worst” task on our to-do list for last. Right? Unfortunately, this only contributes to the dread and anxiety associated with the task. Try flipping the list by doing the most dreaded activity first, when you have the most energy. Suddenly, surprise! You’ve actually created energy for yourself by getting that knocked out, and you are more prepared to tackle the rest of what you’ve lined up for yourself.
FAQs on Anxiety
- Response: Response is the first step in healing from Depression. It involves the first decrease in symptoms, or the first moment in which you “feel better.” Response is the first step toward a higher, more long-lasting level of improvement.
- Remission: Remission is the state of being free of depressive symptoms. You have moved from having moments where you feel better to having days in a row where you do not feel depressed. You may describe a sense of wellbeing that feels entirely different from Depression.
- Recovery: Recovery is the period of time where you’ve been in remission for at least four months, and you can observe both good days and bad days. You are certainly feeling better than when you were depressed, and you may be implementing new skills and strategies to maintain this level of wellbeing. This is no walk in the park; it’s real life, with real ups and downs.
- Relapse: Relapse is a return of a full slate of depressive symptoms prior to reaching four months of remission. Take heart: you have already gotten there once, and you can get there again. Keep applying the strategies that helped you achieve Remission the first time.
- Recurrence: Recurrence is the appearance of another depressive episode after you’ve attained full Recovery. Again, this is disheartening, but not disastrous. After reaching Recovery at least once, you can return to the skills and strategies that have worked in the past.
- Persistent low, depressed mood
- Loss of pleasure in previously enjoyable activities
- Low energy or fatigue
The drug of choice for depression is more accurately a category of choice, and that is SSRIs (Selective Serotonin Reuptake Inhibitors). This category includes Prozac (fluoxetine), Zoloft (sertraline), Celexa (citalopram) and other names you’ve heard on commercials, social media, or from friends. These drugs allow serotonin (a feel-good chemical) to stay in the brain longer, promoting a higher sense of well-being.
- Acute: Acute treatment is the early part of therapy, where are you working to establish relief from the daily symptoms of depression. It’s hard work, but you get glimmers of hope when you achieve moments or days of remission.
- Continuation: Continuation is the stage of treatment wherein you are working to establish habits that prevent a relapse into symptoms of depression. You and your therapist have found skills and strategies that work for you, and your job is to turn to build these into your daily life.
- Maintenance: Maintenance is the stage of treatment where you are working to prevent recurrence of depression. Your effective habits are well-established, and you know how to respond to triggers or stressors that are likely to bring on symptoms of depression.
Alternative and Complementary Treatments in depression
- Acupuncture is a traditional Chinese medicine wherein trained practitioners use their knowledge of the body and qi (a naturally occurring energy within the body) to precisely insert tiny needles into the very top surface of the skin. The result is often a mitigation of a targeted symptom, whether psychological or physical.
- Biofeedback is a treatment taught by trained professionals, wherein you learn to monitor your own vital systems (i.e. heart rate, breathing) to calm those systems, also easing the symptoms of anxiety and/or depression that accompany their rise.
- Herbal Remedies are another type of traditional Chinese medicine wherein practitioners administer carefully dosed ground dried herbs for ingestion. The goal is, again, to decrease psychological or physical discomfort.
- Massage/Reflexology are both forms of body work that can provide physical relief of tense muscles, which can also aid in promoting relaxation and a higher level of wellbeing.
- Meditation is an alternative intervention that more and more therapists are incorporating into traditional psychotherapy. It involves intentional quiet time, often with a focus on breath. Regular meditation practices have been demonstrated to have a positive impact on psychological distress.
Potential benefits and Risks of depression
Brain Stimulation Therapies in depression
- Electroconvulsive Therapy (ECT) is a medical procedure used for treatment-resistant depression or bipolar disorder. ECT happens in a hospital, while you are asleep. A trained physician, or team of practitioners, applies electrodes to your head, which send controlled electrical impulses that trigger a very brief seizure. The seizure stimulates the neurons and chemicals in your brain in a way that helps disrupt the patterns associated with your mental illness. After a few minutes, you wake up with no memory of the procedure. Generally, ECT is done two or three times a week for about six to 12 treatments total. The American Psychiatric Association (APA) reports that ECT provides symptom mitigation for up to 80% of patients that undergo the procedure.
- Vagus Nerve Stimulation involves an initial surgery to implant a small device (called a pulse generator) next to one of the two vagus nerves (a large nerve running from your brain to your stomach) in your body. After recovery from surgery, your doctors work to figure out the optimal frequency for stimulating your vagal nerve. The most common pattern is a 30-second stimulation every five minutes.
- Repetitive Transcranial Magnetic Stimulation (rTMS) is a procedure that uses electromagnetic pulses to stimulate your brain. Like ECT and VNS, rTMS is done by a doctor who holds an electromagnetic coil next to your head. You will hear/feel the pulses as “tapping,” and you’ll have to wear earplugs because the machine is quite noisy. Each procedure takes 30-40 minutes, and you generally undergo the procedure five days a week for about a month.
Effectiveness and Side Effects of depression
- ECT is generally quite effective, with the APA reporting symptom mitigation in up to 80% of individuals that go through it. However, on the day of the procedure, it is not uncommon to experience nausea, headache, confusion, fatigue, and temporary memory loss. If you are in the majority of people who experience relief from psychological symptoms, these temporary side effects may be a small price to pay for feeling better.
- Vagus Nerve Stimulation is a long-term treatment, so relief does not usually come quickly. A study in Biological Psychiatry showed that 27% of people undergoing VNS saw improvement in their depressive symptoms. Aside from the long duration of treatment prior to substantial improvement, the side effects are minimal and usually involve minor discomfort during the procedure itself.
- rTMS can be quite effective for depression, with studies generally showing that 50-60% of people who undergo the treatment report some improvement, and 30% of that group experience complete remission. The primary side effects during and right after treatment include headaches (treatable with OTC medication) and lightheadedness. Unfortunately, the improvement noted following rTMS is not always permanent, and the procedure may need to be repeated.
Brain stimulation therapies are often used when more traditional psychotherapy, or talk therapy, has proven ineffective. Sometimes depression that has not responded to other interventions is referred to as “treatment-resistant.” When this occurs, in a minority of cases, you may want to talk to your physician about somewhat more invasive brain stimulation techniques.
