Which mental health disorder is characterized by persistent low mood and loss of interest?

Major depressive disorder is indeed characterized by persistent low mood and a loss of interest or pleasure in activities once enjoyed. This condition often involves a range of symptoms that may affect an individual's ability to function in daily life. The persistent nature of these symptoms distinguishes major depressive disorder from other mood disorders.

In major depressive disorder, individuals may experience significant changes in sleep patterns, appetite, energy levels, as well as feelings of worthlessness or excessive guilt. The emotional impact is profound; the low mood can last most of the day, nearly every day. This disorder can also manifest with cognitive changes, such as difficulty concentrating or making decisions.

Understanding the symptoms associated with major depressive disorder is crucial for effective diagnosis and treatment, emphasizing the importance of recognizing persistent low mood and disinterest as central characteristics.
