Major Depressive Disorder:
Still Undertreated Despite Growing Awareness

Depression is one of the most talked-about mental health conditions of our time, yet nearly a third of people who have it receive no treatment at all. In Virginia and across the country, the gap between how many people need care and how many actually receive it remains wide. This article explains what major depressive disorder (MDD) actually is, why it so often goes untreated, and what evidence-based options exist today.

What Is Major Depressive Disorder?

Major depressive disorder is a mood disorder with biological, psychological, and social dimensions. It is not sadness caused by a hard week, and it is not a character flaw or a sign of weakness. It is a medical condition that changes how the brain functions and how a person experiences the world.

A diagnosis of MDD requires five or more of the following symptoms to be present for at least two weeks, with at least one being depressed mood or loss of interest:

• Persistent depressed mood most of the day, nearly every day
• Loss of interest or pleasure in almost all activities (anhedonia)
• Significant changes in appetite or weight
• Insomnia or sleeping too much
• Physical slowing or agitation noticeable to others
• Fatigue or loss of energy nearly every day
• Feelings of worthlessness or excessive guilt
• Difficulty concentrating or making decisions
• Recurrent thoughts of death or suicidal ideation

Depression can arise without any obvious external trigger. A person can have a stable job, a loving family, and every reason to feel okay, and still be experiencing a depressive episode. This is part of why it is so misunderstood.

How Common Is It?

Major depressive disorder affects roughly 1 in 6 U.S. adults over the course of a lifetime and is the leading cause of disability worldwide in the 15 to 44 age group. Rates rose sharply during the COVID-19 pandemic and have not fully returned to pre-pandemic levels. Women are diagnosed at roughly twice the rate of men, though this gap likely reflects differences in help-seeking behavior as much as actual prevalence.

The Anxiety-Depression Overlap

One of the most clinically important and underappreciated facts about MDD is how commonly it occurs alongside anxiety. Studies suggest that nearly three quarters of people with major depressive disorder also experience significant anxiety symptoms. This overlap matters because it affects how depression presents and how it should be treated.

People with anxious depression often have more severe symptoms, a more chronic course, and a greater risk of relapse than those with depression alone. They may also be less likely to seek help because the anxiety component keeps them from taking action. If you have been told you have anxiety but still feel persistently low, flat, or hopeless, it is worth asking whether depression is also part of the picture.

Why Does It Go Untreated?

Several factors contribute to the treatment gap:

• Stigma: Despite decades of awareness campaigns, many people still feel shame about having depression or fear how others will perceive them if they seek help.
• Misattribution: Depression is often attributed to situational stress, burnout, or laziness rather than recognized as a medical condition. See our article on burnout vs. depression for how to tell them apart.
• Access barriers: Finding a psychiatrist who is accepting new patients, has availability within a reasonable time, and accepts your insurance can be genuinely difficult in many parts of Virginia. Telehealth has helped close this gap substantially.
• Minimizing symptoms: Many people with depression tell themselves they should be able to push through it, or that others have it worse, and delay seeking care for years.

What Actually Works?

Antidepressant Medication

SSRIs (selective serotonin reuptake inhibitors) and SNRIs (serotonin-norepinephrine reuptake inhibitors) are first-line pharmacological treatments for MDD. They are effective for moderate to severe depression and have a well-established safety profile. Finding the right medication often requires some adjustment, and most antidepressants take several weeks to reach their full effect. Bupropion, mirtazapine, and other classes may be used depending on the clinical picture.

Psychotherapy

Cognitive Behavioral Therapy (CBT) is the most extensively studied psychotherapy for depression and has strong evidence for mild to moderate MDD. Behavioral Activation, Interpersonal Therapy (IPT), and Acceptance and Commitment Therapy (ACT) are other evidence-based approaches. For many people, therapy plus medication outperforms either treatment alone.

Lifestyle and Supportive Measures

Regular physical exercise has been shown to reduce depressive symptoms with effect sizes comparable to antidepressants in mild to moderate depression. Sleep hygiene, nutrition, social connection, and reducing alcohol use all play supporting roles. These are not replacements for treatment when depression is moderate to severe, but they are meaningful contributors to recovery.

When First-Line Treatments Are Not Enough

Roughly a third of people with MDD do not achieve full remission with the first antidepressant tried. When this happens, options include augmentation strategies, switching medications, or in some cases referral for specialized treatments such as transcranial magnetic stimulation (TMS). A thorough evaluation helps identify which path makes sense.
