At Aucoin & Associates Psychology Practice in Lafayette, LA, we aim to provide clear, clinical education on depression to help individuals and their families understand the condition, recognize symptoms, and seek timely, effective care.
What is Depression?
Depression, also referred to as Major Depressive Disorder (MDD) or clinical depression, is a common and serious mood disorder characterized by persistent feelings of sadness, hopelessness, and a loss of interest or pleasure in most activities. It affects how a person thinks, feels, and functions in daily life.
Depression is more than occasional sadness. According to the DSM-5 (APA, 2013), a diagnosis of Major Depressive Disorder requires the presence of at least five symptoms for two weeks or longer, one of which must be either depressed mood or loss of interest/pleasure.
These symptoms must represent a change from prior functioning and cause clinically significant distress or impairment in social, occupational, or other important areas of life.
Core Symptoms of Depression
Symptoms may include:
- Persistent sad, empty, or anxious mood
- Loss of interest or pleasure in hobbies and activities
- Feelings of hopelessness or pessimism
- Irritability, frustration, or restlessness
- Fatigue or decreased energy
- Difficulty concentrating, remembering, or making decisions
- Sleep disturbances (insomnia or hypersomnia)
- Appetite or weight changes
- Feelings of worthlessness, guilt, or helplessness
- Physical symptoms without a clear cause (e.g., headaches, digestive issues)
- Thoughts of death or suicide, or suicide attempts
Not everyone with depression experiences all symptoms. Some may have somatic complaints, while others may feel emotionally numb or disconnected.
Types of Depressive Disorders
Major Depressive Disorder (MDD)
This is the most widely recognized form of depression and involves episodes of severe symptoms that interfere with daily functioning.
Persistent Depressive Disorder (PDD, formerly dysthymia)
PDD is characterized by a depressed mood lasting at least two years (or one year for children and adolescents). Symptoms are less severe but more chronic and may include low self-esteem, fatigue, and irritability.
Postpartum Depression
A form of depression that affects some women after childbirth, involving intense sadness, anxiety, and exhaustion.
Seasonal Affective Disorder (SAD)
SAD is a subtype of depression triggered by seasonal changes, most commonly emerging during the fall and winter months.
Premenstrual Dysphoric Disorder (PMDD)
A severe form of premenstrual syndrome that includes mood swings, irritability, and depression during the luteal phase of the menstrual cycle.
Depression In different Populations
In Adults
Adults may experience depression as a loss of motivation, chronic fatigue, irritability, and withdrawal from relationships. It often co-occurs with anxiety, substance use, and chronic pain conditions.
In Adolescents
Teen depression may manifest as irritability, academic decline, social withdrawal, or somatic complaints. It’s sometimes mistaken for “typical teenage behavior,” delaying diagnosis.
In Older Adults
Symptoms in older adults may be misattributed to aging or physical illness. Watch for unexplained aches, memory problems, or withdrawal from social engagement.
Depression in the Acadiana Region
While depression affects people worldwide, it’s important to recognize local challenges and resources. In Lafayette and the broader Acadiana area, individuals may face barriers to mental health care such as stigma, transportation, or limited rural access. Aucoin & Associates is proud to offer accessible depression treatment options tailored to the unique needs of our South Louisiana communities.
Depression and Co-occurring Conditions
Depression often exists alongside other mental health conditions, such as:
- Anxiety disorders
- ADHD
- Substance use disorders
- PTSD
- Bipolar disorder
A comprehensive mental health evaluation is essential to determine whether depression is part of a broader diagnostic picture.
When to Seek Help
If you or a loved one is experiencing symptoms of depression that last longer than two weeks, interfere with functioning, or cause distress, it’s time to seek professional support.
