Which term describes a psychiatric disorder characterized by extreme sadness and loss of interest?

The term that describes a psychiatric disorder characterized by extreme sadness and loss of interest is "depression." This condition often leads to a significant decrease in motivation to engage in activities that an individual once found enjoyable or fulfilling. Additionally, depression can affect various aspects of life including emotional well-being, physical health, and daily functioning. Symptoms may include feelings of hopelessness, changes in appetite or sleep patterns, and difficulty concentrating.

In contrast, meditation and visualization are techniques often used for relaxation and mental clarity rather than psychiatric disorders. Anxiety pertains to excessive worrying and fear, which differs from depression’s core symptoms of sadness and loss of interest. Understanding the distinction among these terms is vital for recognizing mental health issues and their appropriate interventions.
