Q & A

What is Major Depressive Disorder (MDD)?

Major Depressive Disorder is a condition where a person experiences a severely depressed mood that causes significant distress or impairment in social, occupational, or other areas of their life. It goes beyond temporary sadness and results in lasting, profound changes in the individual's overall functioning.

How does Major Depressive Disorder differ from everyday sadness?

While everyone experiences sadness from time to time, Major Depressive Disorder is characterized by a persistent and overwhelming low mood that lasts for at least two weeks, impacting a person’s daily life. It involves significant changes in emotional state, behavior, and overall functioning, whereas sadness in daily life is typically temporary and less disruptive.

What is anhedonia, and how does it relate to MDD?

Anhedonia refers to the loss of pleasure in activities that a person once enjoyed. It is a key symptom of Major Depressive Disorder and can lead to a person withdrawing from social activities, hobbies, or interests that were once fulfilling.

What are some common symptoms of Major Depressive Disorder?

Common symptoms include a persistently depressed mood, significant weight changes, changes in appetite, sleep disturbances (insomnia or hypersomnia), psychomotor agitation or slowness, feelings of worthlessness or guilt, difficulty concentrating, and recurrent thoughts of suicide.

How is Major Depressive Disorder diagnosed according to the DSM-5?

To be diagnosed with Major Depressive Disorder, a person must exhibit at least five of the symptoms listed in the DSM-5, with at least one of those symptoms being either anhedonia or a depressed mood most of the day, nearly every day, for at least two weeks.

Can Major Depressive Disorder occur more than once in a person's life?

Yes, Major Depressive Disorder can occur as a single episode or multiple times throughout a person's life, with symptoms reappearing at various points.

What is Persistent Depressive Disorder (PDD)?

Persistent Depressive Disorder, also known as dysthymia, is a chronic form of depression where a person experiences depressive symptoms for at least two years. Although the symptoms may be less severe than those of Major Depressive Disorder, they still have a significant impact on the person’s daily functioning.

How does Persistent Depressive Disorder compare to Major Depressive Disorder?

Persistent Depressive Disorder lasts much longer, with symptoms occurring for at least two years, whereas Major Depressive Disorder is defined by a more intense but shorter period of symptoms (at least two weeks). Both conditions can involve similar symptoms, such as low self-esteem, fatigue, and changes in appetite, but PDD is chronic and may not be as intense.

What role does psychomotor agitation or slowness play in Major Depressive Disorder?

Psychomotor agitation refers to restlessness or physical signs like shaking, while psychomotor slowness involves delayed or slower movements. These symptoms can manifest in individuals with Major Depressive Disorder, often contributing to feelings of fatigue or low energy.

Why is it important to be mindful of suicide risk in individuals with Major Depressive Disorder?

Individuals with Major Depressive Disorder may experience recurrent thoughts of suicide, and this is a critical risk factor. It is essential to be mindful of this risk to provide appropriate support, early intervention, and ensure the safety of the person.
