5 Causes of Severe Depression – Insights from Lyte Psychiatry, Best Psychiatrist in Arlington & Dallas, TX

Depression isn’t just feeling “sad” or having a rough week—it’s a serious mental health condition that affects how you think, feel, and function. And for many, it can show up without warning, disrupting life at school, work, and home.

At Lyte Psychiatry, we work with both adults and adolescents across Arlington and Dallas, offering personalized evaluations and treatment for people battling depression—mild, moderate, and severe. If you or someone you love is stuck in a deep emotional fog, know that you’re not alone, and more importantly—help is within reach.

Let’s explore 5 common causes of severe depression, based on the latest science and clinical insights.

1. Genetics & Family History

Depression often runs in families. If one or both of your parents experienced depression or another mood disorder, your risk increases. But genes aren’t fate—they’re just one piece of the puzzle.

🧬 A study published by Harvard Health confirms that people with a first-degree relative (parent or sibling) with depression are 2 to 3 times more likely to develop it themselves.

2. Trauma & Childhood Adversity

Experiencing trauma—especially at a young age—can fundamentally change how the brain processes stress and emotion. This includes physical, emotional, or sexual abuse, neglect, bullying, or unstable home environments.

Trauma can quietly sit in the background for years before surfacing as depression, anxiety, or PTSD later in life. That’s why we take trauma-informed care seriously at Lyte Psychiatry.

3. Chronic Stress & Life Events

Stressful life transitions—like losing a job, divorce, financial strain, or the death of a loved one—can trigger episodes of severe depression. The brain and body are deeply connected, and prolonged stress can lead to burnout, emotional exhaustion, and mood collapse.

According to the National Institute of Mental Health (NIMH), situational factors often serve as the tipping point for depressive episodes, especially in those already at risk.

4. Hormonal & Medical Factors

Depression isn’t just emotional—it can also be physiological. Conditions like thyroid imbalances, chronic pain, autoimmune diseases, or hormonal shifts (like postpartum or perimenopause) can affect mood regulation.

🩺 This is why our psychiatric evaluations at Lyte Psychiatry include a whole-person approach—we consider both mind and body before making any diagnosis or treatment recommendation.

5. Brain Chemistry & Neurotransmitter Imbalance

Low levels of key brain chemicals like serotonin, dopamine, and norepinephrine are strongly linked to clinical depression. These imbalances affect mood, energy, motivation, and sleep—creating a snowball effect that can lead to severe symptoms.

Modern psychiatry now uses a combination of talk therapy, medication, and lifestyle changes to restore balance—and hope.
