Depression is one of the most common yet misunderstood mental health disorders affecting millions of people worldwide. It goes far beyond occasional sadness or temporary emotional lows — it is a serious condition that affects how you feel, think, and function in daily life. What are the Signs of Depression?
Recognizing the signs of depression is crucial for early intervention and recovery. Whether you’re concerned about yourself or someone you care about, understanding the symptoms is the first step toward seeking help.
🧠 What Is Depression?
Depression, also called Major Depressive Disorder (MDD), is a mental illness characterized by persistent feelings of sadness, hopelessness, and a lack of interest or pleasure in most activities. It can affect anyone — regardless of age, gender, or background — and it often impacts everyday activities like work, sleep, appetite, and relationships.
According to the World Health Organization, depression is a leading cause of disability worldwide.
🔍 What Are the Signs of Depression?
Depression can manifest in many different ways. The signs can be emotional, physical, cognitive, and behavioral. It’s important to remember that symptoms can vary from person to person and may change over time.
