Depression (major depressive disorder or clinical depression) is a common but serious mood disorder. It causes severe symptoms that affect how you feel, think, and handle daily activities, such as sleeping, eating, or working.

Some people view depression as a cause to feel low, inactive, or not be able to have strength to do anything. Simply, the state of been depressed may seem normal to them; while some view depression as a phase that may fade with time, when event that led to their state of been depressed wipe off their memory.

On the contrary, Medical experts has described depression as a “real illness that impacts the brain”. Depression is not regarded as normal or a feeling associated with just being “down”. It is a serious illness that is caused by the changes in brain chemistry. Depression is not only serious mental illness; it is also common among men and women.

According to world health organization (WHO), depression is one of the most disabling disorders in the world, affecting 1 in 5 women 1 in 10 men at some point in their lifetime. The estimated percentage was 21% of women and 12% of men in reference to United States.

Factors responsible

Recent research suggests that depression can be caused by a combination of genetic, biological, environmental, and psychological factors.

Depression can happen at any age, but often begins in adulthood. Depression is now recognized as occurring in children and adolescents, although it sometimes presents with more prominent irritability than low mood. Many chronic mood and anxiety disorders in adults begin as high levels of anxiety in children.

Depression, especially in midlife or older adults, can co-occur with other serious medical illnesses, such as diabetes, cancer, heart disease, and Parkinson’s disease. These conditions are often worse when depression is present. Sometimes medications taken for these physical illnesses may cause side effects that contribute to depression.
