The symptom of fatigue in any form whether it be acute or chronic can certainly be part and parcel of any sort of dysthymic condition or another words depressive or manic mood disorder. However, fatigue in and of itself is a very nonspecific symptoms and should be taken as a potential opportunity to investigate other types of issues and problems such as anemia, fibroid disease, adrenal disease, and certain types of neurological degenerative problems that can also demonstrate fatigue as part of it symptomatology. One overlooked cause of fatigue often in patients with psychiatric disorders can be very medication that is being used to treat their problem. Therefore, I would also include as part of the questioning to the psychiatrist a review of medications.
