Depression

Depression, also known as Major Depressive Disorder (MDD) or simply major depression, is a common but serious mood disorder that affects how a person feels, thinks, and handles daily activities. It is more than just feeling sad or having a low mood; depression can cause severe emotional and physical problems that interfere with work, relationships, and quality of life.

Key Features of Depression:

Depression is characterized by persistent feelings of sadness, hopelessness, and a lack of interest or pleasure in daily activities. It affects both the mind and body, leading to changes in mood, behavior, and physical health. Key features include:

A. Emotional and Behavioral Symptoms

  • Persistent sadness, emptiness, or hopelessness: A continual feeling of sadness that lasts for weeks or even longer.
  • Loss of interest or pleasure in activities once enjoyed (anhedonia).
  • Feelings of worthlessness or guilt, often for things that were not the individual’s fault.
  • Irritability or frustration over small matters.
  • Difficulty concentrating or making decisions.
  • Social withdrawal or avoidance of social interactions.
  • Decreased motivation to perform daily tasks, including work, personal care, or hobbies.

B. Physical Symptoms

  • Fatigue or lack of energy, even after rest.
  • Sleep disturbances: Insomnia (difficulty sleeping) or hypersomnia (sleeping too much).
  • Changes in appetite or weight (either weight gain or weight loss).
  • Physical pain: Unexplained aches, pains, headaches, or digestive problems.
  • Slowed movements or speech: A noticeable decrease in physical or mental activity.
  • Reduced sexual interest or activity.

C. Thoughts and Cognitive Symptoms

  • Frequent thoughts of death or suicide, or suicidal ideation.
  • Negative thinking patterns, including self-criticism, pessimism, or hopelessness about the future.
  • Difficulty thinking, concentrating, or making decisions.
  • Memory problems or a feeling of being "mentally foggy."
