Which of the following are symptoms of mood disorders?

Mood disorders are characterized by significant disturbances in a person's emotional state and can manifest in various ways. Emotional extremes are a primary symptom of mood disorders. This includes experiencing intense feelings of sadness, hopelessness, and despair in conditions like depression, or periods of extreme euphoria and irritability in conditions such as bipolar disorder. The presence of these extreme emotions can significantly affect a person's day-to-day functioning and overall mental health, making them crucial indicators for the diagnosis of mood disorders.

Disorganized thinking and difficulty in expressing thoughts are more closely associated with cognitive or thought disorders, such as schizophrenia, rather than mood disorders. Erratic muscle movement can occur in various neurological conditions, and while it may appear in some severe cases of certain mood disorders (like psychomotor agitation in depression), it is not a defining symptom of mood disorders themselves. Therefore, the most accurate representation of symptoms specifically linked to mood disorders is emotional extremes.
