Mood Disorders

What are mood disorders?

Mood disorders are psychiatric conditions that cause significant and persistent disruptions in a person’s emotional state. These disorders affect mood regulation, often leading to prolonged periods of sadness, hopelessness, elation, or irritability that interfere with daily functioning, relationships, and physical health. Common mood disorders include depressive disorders, bipolar disorders, cyclothymic disorder, and substance-induced mood disorder. Because these conditions can increase the risk of self-harm or suicide, early diagnosis and treatment are vital to improving safety, stability, and long-term quality of life.

Signs & symptoms

The way mood disorders present can vary depending on the type, but they typically involve ongoing changes in mood, energy, or ability to function. Depressive symptoms can cause persistent sadness and loss of interest, while bipolar disorders often feature shifting periods of elevated energy or mania followed by depression. Symptoms may appear gradually, last for weeks or longer, and often worsen during stressful life events. Without treatment, mood disorders can impair work, relationships, and physical health, and may increase the risk of substance use or suicidal thoughts.

  • Persistent sadness, hopelessness, or emptiness
  • Irritability, agitation, or unpredictable shifts in mood
  • Loss of interest in previously enjoyable activities
  • Difficulty concentrating or making decisions
  • Feelings of worthlessness, guilt, or low self-esteem
  • Racing thoughts or rapid speech during manic episodes
  • Impulsivity or risky decision-making
  • Sleep disturbances (sleeping too little or too much)
  • Noticeable changes in appetite or weight
  • Low energy, fatigue, or slowed movements
  • Nervous tension, restlessness, or agitation
  • Headaches, stomachaches, or other physical complaints without a clear cause
  • Heightened or decreased libido
  • Disrupted sleep with sustained high energy (during mania)

A diagnosis of a mood disorder requires evaluation by a mental health professional. Assessment often includes a psychiatric interview, screening tools, and a review of personal and family medical history. Providers consider the duration and severity of mood changes, rule out medical conditions like thyroid disorders or neurological illnesses, and assess any co-occurring substance use.

Types of mood disorders

Mood disorders represent a broad category of mental health conditions, each with distinct causes and presentations but all marked by long-term disruption of mood regulation. While depressive disorders cause persistent sadness and lack of energy, bipolar disorders and related conditions involve cycles of highs (mania or hypomania) and lows (depression). These variations can present differently in each person but all require treatment to reduce risks and improve quality of life.

Bipolar disorders feature alternating mood episodes that include emotional highs (mania or hypomania) and lows (depression). Symptoms may include intense elation, racing thoughts, reduced need for sleep, impulsive decisions, and severely impaired judgment, often followed by deep sadness, fatigue, or hopelessness. Subtypes include:

  • Bipolar I Disorder: Defined by at least one full manic episode, often severe enough to impair functioning or require hospitalization.
  • Bipolar II Disorder: Characterized by episodes of major depression combined with hypomanic episodes that are less severe than full mania.
  • Manic-Depressive Psychosis: Features extreme manic and depressive episodes, sometimes occurring together, with symptoms that may include delusions or psychosis.
  • Seasonal Bipolar Disorder: Involves mood cycling linked to seasonal changes, with symptoms that intensify at certain times of the year.

Cyclothymic disorder involves chronic mood fluctuations with periods of hypomanic symptoms and depressive symptoms that are less severe than those found in bipolar I or II disorder. These cycles typically last for at least two years in adults. While symptoms may appear milder, they often disrupt daily life and increase vulnerability to developing full bipolar disorder.

Depressive disorders are marked by low mood, loss of pleasure, and reduced interest in daily activities. People with depression often struggle with changes in appetite, disrupted sleep, fatigue, and negative self-perceptions. Types of depressive disorders include:

  • Major Depressive Disorder (MDD): Persistent sadness or emptiness lasting at least two weeks, often with physical and cognitive symptoms.
  • Persistent Depressive Disorder (Dysthymia): Milder but long-lasting symptoms that extend for years.
  • Seasonal Affective Disorder (SAD): A type of depression linked to changes in daylight during fall or winter months.
  • Disruptive Mood Dysregulation Disorder (DMDD): Diagnosed primarily in children and adolescents, involving severe irritability and frequent temper outbursts.
  • Premenstrual Dysphoric Disorder (PMDD): Severe mood changes that occur before menstruation and resolve shortly after it begins.
  • Depression related to a medical condition: Mood symptoms triggered by chronic illnesses like Parkinson’s disease, stroke, or thyroid disease.

Substance-induced mood disorder occurs when mood changes result from the use of drugs, alcohol, medications, or withdrawal. These symptoms often resemble depression or mania and usually improve when the person discontinues the substance. In some cases, however, underlying psychiatric symptoms remain, requiring integrated treatment for both substance use and mood stabilization.

Change isn’t always easy, and it doesn’t happen overnight, but a little discomfort now means real change is just around the corner.

Causes & risks

Mood disorders develop through a complex interaction of biological, psychological, and environmental factors. While research highlights the role of brain chemistry and genetics, stressful or traumatic life experiences can also trigger onset or worsen symptoms.

  • Exposure to childhood trauma or neglect
  • Ongoing life stressors, including poverty or loss of a loved one
  • Living with chronic medical conditions (e.g., heart disease, cancer, Parkinson’s disease)
  • Use of alcohol, street drugs, or certain medications
  • Family history of depression, bipolar disorder, or substance use
  • Abnormal brain chemistry involving serotonin, norepinephrine, or dopamine
  • Co-occurring mental health conditions such as anxiety or PTSD
  • Unhealthy coping styles or cognitive distortions (e.g., black-and-white thinking)
  • Increased risk of suicidal thoughts or behaviors, particularly during severe episodes

Treatment programs

Capella Recovery Center provides structured, evidence-based treatment for individuals experiencing mood disorders. We design personalized care plans that combine therapy, medication management, and psychosocial support to stabilize symptoms and promote lasting recovery. Our programs teach patients strategies to identify triggers, regulate emotions, and strengthen resilience.

Residential inpatient

In our residential program, patients receive 24/7 support from a multidisciplinary team in a safe, structured environment. Treatment plans may include cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT), medication management, trauma-informed care, or other evidence-based interventions tailored to the individual’s needs. Ongoing monitoring allows clinicians to adjust care for the best outcomes.

Aftercare planning

Recovery continues after residential treatment through step-down levels of care, such as partial hospitalization programs (PHP) or intensive outpatient programs (IOP). These services may include continued therapy, relapse prevention, medication management, and skill-building groups that prepare each individual for daily life.

Alumni community

The Capella alumni program helps former patients maintain progress by fostering long-term connection. Through peer groups, mentorship, and community gatherings, alumni build supportive relationships that reinforce recovery and resilience.
