Depression

Depression is a common, treatable condition that affects mood, thinking, sleep, and daily functioning—more than a temporary low mood.

While it is normal to feel sad or discouraged occasionally, depression goes beyond temporary low mood. It can interfere with work, relationships, sleep, and overall well-being. Left untreated, symptoms may become more severe and lead to long-term distress

Although depression is serious, it is also highly treatable. Many people improve significantly with professional support, including therapy, medication, or a combination of approaches.

Types include major depressive disorder, persistent depressive disorder, postpartum depression, seasonal affective disorder, and others.

Effective care often combines psychotherapy, antidepressant medications, and lifestyle strategies; advanced options are available for treatment-resistant depression.

Understanding Depression

Depression is not a sign of weakness or something a person can simply “snap out of.” It involves changes in brain chemistry, thought patterns, and behavior that affect everyday functioning. Symptoms may develop gradually or appear suddenly and can last for weeks, months, or longer if not addressed.

People of all ages and backgrounds can experience depression, and the condition can take several forms depending on its severity, duration, and underlying causes.

Types of Depressive Disorders

Several depressive disorders are recognized, each with specific features:

• Major Depressive Disorder (MDD): Persistent low mood, loss of interest in activities, and difficulty with daily responsibilities.
• Persistent Depressive Disorder (Dysthymia): Long-lasting symptoms (two years or more), often less intense but still disruptive.
• Minor Depression: Symptoms lasting two weeks or more but not meeting full criteria for major depression.
• Postpartum Depression: Intense mood changes after childbirth that interfere with self-care and bonding.
• Seasonal Affective Disorder (SAD): Depression tied to seasonal changes, often in winter.
• Psychotic Depression: Major depression with delusions or hallucinations.
• Bipolar Disorder: Involves cycles of depression and elevated mood.
• Disruptive Mood Dysregulation Disorder (DMDD): Severe irritability and outbursts in children or adolescents.

Major Depression

Major depression is a serious form of depression marked by persistent feelings of sadness, hopelessness, or loss of interest in activities once enjoyed. Symptoms typically last for weeks or longer and can significantly impair daily life.

It is one of the leading causes of disability worldwide and is associated with higher risks of chronic health conditions, social difficulties, and even premature mortality. Without treatment, major depression can worsen over time and increase the risk of suicide, heart disease, and impaired functioning. With proper care, however, many people experience meaningful recovery.

Causes and Risk Factors

The exact cause is not fully understood, but contributing factors may include:

• Family history of depression or other mental health conditions
• Long-term stress or trauma
• Chronic health conditions such as diabetes or heart disease
• Hormonal changes or thyroid disorders
• Certain medications or substance use
• Major life events such as loss, divorce, or isolation
• Personality traits such as low self-esteem or pessimism

Depression often coexists with conditions like anxiety, PTSD, or substance use, which may complicate diagnosis and treatment.

Common Symptoms

Major depression may include:

• Low mood or emotional numbness
• Loss of interest in hobbies or social activities
• Fatigue or low energy
• Changes in appetite or weight
• Trouble sleeping or sleeping too much
• Feelings of worthlessness, guilt, or hopelessness
• Difficulty concentrating or making decisions
• Irritability or restlessness
• Withdrawal from friends or family
• Thoughts of death or suicide

Causes and Risk Factors of Depression

In general, depression results from a mix of biological, genetic, environmental, and psychological influences. Imbalances in brain chemicals, stressful life events, hormonal shifts, or chronic illnesses can all contribute. Recognizing these factors helps guide effective treatment.

Diagnosis

Diagnosis is made through a clinical evaluation by a healthcare provider or mental health professional. This often includes discussing symptoms, personal and family history, lifestyle factors, and may involve standardized screening tools. Lab tests may be ordered to rule out conditions like thyroid disorders or vitamin deficiencies that can mimic depression.

Treatment Options

Depression is highly treatable, and most people improve with a structured approach to care. Treatment may include:

Therapy

Cognitive Behavioral Therapy (CBT) and other evidence-based approaches help people identify negative thought patterns, build coping skills, and address root causes of distress. Therapy may be individual, group, or family-based.

Medication

Antidepressants regulate brain chemicals linked to mood. They may take several weeks to work and often require close monitoring and adjustments. Stopping medication suddenly should be avoided without medical guidance.

Spravato (Esketamine) for Major Depression

At Connecticut Behavioral Health Associates (CBHA), we offer Spravato (esketamine) for adults with treatment-resistant depression or major depressive disorder with suicidal thoughts or behaviors. This FDA-approved treatment is administered in a clinical setting and has provided relief for many individuals who have not responded to traditional approaches.

Other Treatments

For those with severe or treatment-resistant depression, additional options may include:

• Electroconvulsive therapy (ECT)
• Transcranial magnetic stimulation (TMS)
• Ketamine infusion therapy
• Light therapy for seasonal depression
• Mindfulness practices, yoga, or meditation
• Lifestyle adjustments such as exercise, sleep, and nutrition

In more severe cases, inpatient or intensive care may be necessary to ensure safety and stabilization.

Outlook and Long-Term Care

With the right treatment, many people recover fully from depression, while others manage it as a long-term condition. Preventive strategies—such as ongoing therapy, maintenance medication, or regular provider check-ins—can help reduce relapse risk. Early intervention is key to improving outcomes.

When to Seek Help

Seek help if symptoms last more than two weeks or interfere with daily life. Immediate support is critical if you or someone you know experiences suicidal thoughts, hallucinations, or an inability to perform daily tasks.

You are not alone—effective treatments are available. Reach out to a trusted healthcare provider, counselor, or crisis line if you need urgent help.
