Final answer:

Step-by-step explanation:
True
Severe depression and dysthymia are indeed highly comorbid with many other mental disorders, particularly anxiety disorders. Comorbidity refers to the simultaneous presence of two or more disorders in an individual. Depression and dysthymia, which are major mood disorders, often co-occur with anxiety disorders like obsessive-compulsive disorder (OCD), panic disorders, posttraumatic stress disorder (PTSD), and specific phobias. It is common for individuals with depression or dysthymia to also experience symptoms of anxiety, and vice versa.
