Depression

Medically reviewed: February 6, 2026 Updated: February 6, 2026

Depression is more than feeling sad—it’s a treatable mental health condition that can affect mood, sleep, energy, and daily functioning.

Key Facts About Depression

  • Depression can affect emotions, thinking, physical health, and daily functioning—not just mood. 1
  • Evidence-based treatments include psychotherapy, medication, or a combination depending on severity and history. 3-5
  • Depression can present as irritability, numbness, or physical symptoms—not only sadness. 1
  • If depression includes thoughts of suicide or self-harm, urgent support is available (call/text 988 in the U.S.). 1

Depression (often called major depressive disorder or clinical depression) is a medical condition that can change how you feel, think, and act. It can affect your energy, sleep, appetite, concentration, and relationships—not just your mood.1

Depression is common and treatable. Many people improve with evidence-based therapy, medication, or a combination—especially when treatment is matched to symptom severity, safety needs, and co-occurring conditions (like anxiety, trauma symptoms, or substance use).3-5

What depression can look like (it’s not always “sadness”)

Depression can show up differently from person to person. Some people feel deeply sad; others feel numb, irritable, or “shut down.” Depression can also include:

  • Loss of interest in things you used to enjoy
  • Feeling slowed down, exhausted, or unmotivated
  • Harsh self-criticism, guilt, or hopelessness
  • Physical symptoms such as headaches or stomach problems with no clear cause1

Common types of depressive disorders

  • Major depression: symptoms most of the day, nearly every day, for at least 2 weeks, with meaningful impact on life.1
  • Persistent depressive disorder: a longer-lasting pattern (often 2 years or more), sometimes less intense but still impairing.1
  • Seasonal affective disorder (SAD): depression that follows a seasonal pattern, often worse in winter months.1
  • Perinatal depression: depression during pregnancy or after childbirth that is more serious than short-term “baby blues.”1

Why depression happens (most of the time it’s “multiple causes”)

Depression usually doesn’t have just one cause. It’s often influenced by a mix of biological factors, family history, life experiences, ongoing stress, and health conditions. Sleep disruption, chronic stress, and substance use can also worsen symptoms and make recovery harder.1

Why a careful assessment matters

Some symptoms of depression can overlap with other conditions, including bipolar disorder. If someone has ever had periods of unusually high energy, very little sleep without feeling tired, or risky behavior, it’s important to evaluate for bipolar disorder because treatment plans can differ.1


At Advanced Health and Education in Eatontown, New Jersey, our clinical team creates individualized depression treatment plans that may include cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT), and medication management. Whether you need residential stabilization, a partial hospitalization program (PHP), or a step down to intensive outpatient care, we match treatment intensity to where you are right now.

Signs & Symptoms of Depression

Depression can affect emotions, thoughts, body, and behavior. Symptoms vary, but they usually last long enough and feel intense enough to interfere with daily life.

  • Persistent low mood

    Feeling sad, empty, or “down” most of the day, nearly every day.

  • Loss of interest or pleasure

    Activities you used to enjoy feel pointless or uninteresting.

  • Sleep disruption

    Trouble falling asleep, waking too early, or sleeping much more than usual.

  • Low energy or fatigue

    Feeling drained, slowed down, or exhausted even with rest.

  • Appetite or weight changes

    Eating much more or less than usual, with weight changes.

  • Difficulty concentrating

    Trouble focusing, remembering, or making decisions.

  • Guilt or worthlessness

    Harsh self-criticism or feeling like a burden.

  • Hopelessness

    Belief that things won’t improve, even when others are supportive.

  • Irritability or anger

    Feeling “on edge,” snapping easily, or increased frustration.

  • Physical aches/pains

    Headaches, stomach issues, or body pain without a clear medical cause.

  • Withdrawal/isolation

    Avoiding people, responsibilities, and routines.

  • Thoughts of death or suicide

    Passive or active thoughts; seek immediate help if you can’t stay safe.

Causes & Risk Factors

Depression usually develops from a combination of factors rather than one single cause.

Family history & genetics

Having relatives with depression can increase vulnerability, though it doesn’t guarantee you’ll develop it.

Chronic stress

Long-term stress can affect sleep, mood regulation, and coping capacity.

Trauma or major life events

Loss, abuse, relationship changes, or other stressful events can raise risk.

Medical conditions

Some health problems and medications can contribute to depression symptoms.

Substance use

Alcohol and drugs can worsen mood symptoms and interfere with treatment.

How Depression Is Diagnosed

Diagnosis is typically based on a clinical evaluation, not a single lab test.

  1. Clinical interview - A clinician asks about symptoms, how long they’ve lasted, and how they affect life.
  2. Screening tools - Questionnaires may help measure symptom severity and track progress over time.
  3. Medical review - Sometimes medical causes (like thyroid issues) are considered and ruled out.
  4. Safety assessment - Providers assess for self-harm risk and create a plan if safety is a concern.
  5. Evaluation for co-occurring conditions - Anxiety, PTSD, substance use, and bipolar symptoms can change treatment planning.

Levels of Care for Depression

The right level of care depends on safety, symptom severity, and how much depression is disrupting day-to-day life.
