Review: Understanding Depression and Its Common Symptoms

Infographic: Common symptoms of depression

Depression is a serious mental health condition that goes beyond occasional sadness. It can affect how a person thinks, feels, and functions in daily life. Recognizing the symptoms early is important for seeking help and support.

What Is Depression?

Depression (also called major depressive disorder) is a mood disorder characterized by a persistent low mood and loss of interest in activities. It can affect emotional well-being, motivation, sleep, appetite, energy levels, and concentration.

Key Symptoms of Depression

• Persistent sadness or low mood lasting most of the day, nearly every day.
• Loss of interest or pleasure in activities once enjoyed.
• Changes in appetite or weight (increase or decrease).
• Sleep disturbances such as insomnia or oversleeping.
• Fatigue or loss of energy even without physical exertion.
• Feelings of worthlessness or excessive guilt.
• Difficulty concentrating or making decisions.
• Psychomotor changes (restlessness or slowed movements).
• Recurrent thoughts of death or suicide — this is a medical emergency and requires immediate help.

When to Seek Professional Help

If you or someone you know is experiencing several of these symptoms consistently for more than two weeks — especially thoughts of self-harm — it’s important to talk to a mental health professional. Depression is treatable with therapy, medication, lifestyle changes, and social support.
