What are the Symptoms of Depression? How to Identify the Signs

Depression is a prevalent but serious illness shared by millions of people across the world. It is not a state of transient melancholy and can interfere with daily functions, relationships, as well as physical well-being. Identification of depression is essential to seek appropriate help and treatment in a timely manner.

In this overall guide, we will be looking at the emotional, physical, and behavioral symptoms of depression, and the way depression can be distinguished from occasional sadness. We will also be looking at when one should seek professional assistance and the available treatments for it.

Understanding depression: More than sadness

Depression, also called major depressive disorder (MDD), is a mood disorder that involves persistent sadness, hopelessness, and a loss of interest in activities one used to enjoy. Everyone gets the blues from time to time, but depression occurs over the course of weeks, months, or even years and seriously affects a person’s capacity for daily functions.

The World Health Organization (WHO) states that more than 280 million people globally are affected by depression, which is a primary cause of disability. While it affects so many, most individuals fail to identify the symptoms or are afraid of seeking help because of embarrassment or lack of understanding.

Common Symptoms of Depression

Depression impacts people differently, yet there are certain emotional, cognitive, physical, and behavioral indicators to look for.

1. Emotional Symptoms

The most familiar depression indicators are emotional. They include:

• Persistent low spirits or low mood – Feeling sad, empty, or tearful for much of the day.
• Hopelessness – The belief that situations will not get any better.
• Guilt or worthlessness – Self-blame or feeling you are a burden.
• Irritability or frustration – Easily annoyed by even the smallest things.
• Loss of interest in hobbies – No longer finding enjoyment in activities which previously gave you joy.
