Depression is the leading cause of disability globally, significantly impacting individuals' ability to function in daily life, work, and maintain relationships. This mental illness affects people of all ages and backgrounds, leading to a wide range of symptoms such as persistent sadness, loss of interest in activities, fatigue, and difficulty concentrating. The World Health Organization and other health authorities have highlighted depression as a substantial contributor to the global burden of disease, emphasizing how it impairs overall functioning and quality of life.

While anxiety disorders, bipolar disorder, and schizophrenia also have profound effects on individuals and can lead to disability, depression's prevalence and widespread impact on everyday functioning place it at the forefront of mental health concerns. The high rates of comorbidity with other conditions can further exacerbate its effects, making effective treatment and management crucial in addressing its debilitating nature.
