Maybe it’s not depression
Symptoms of illnesses that have physical causes, such as thyroid conditions and infection, can mimic those of depression. Certain medications can cause them too. Your doctor can make a diagnosis only on the information you provide, so it’s important to recognize what’s important to tell her about what you’re experiencing.
Low energy, lack of interest in things once found pleasurable, fatigue and difficulty concentrating are typical symptoms of depression. But, here are some other conditions that are characterized by similar symptoms.
The thyroid gland pumps out hormones that regulate metabolism, heart rate and body temperature. Imbalances in these hormones can cause depressed mood, weight loss or gain, fatigue, memory and concentration problems –just like depression.
“An evaluation of mood problems should include a check of your thyroid status, ” says Phelps. If your doctor doesn’t mention it, he suggests you wonder aloud about whether it might be a good idea.
Bipolar disorder is often misdiagnosed as major depression. It’s important to diagnose it correctly, because if bipolar disorder is treated with antidepressants, your condition may not improve and can even worsen.
Other conditions that mimic depression include:
Sleep disorders, such as ongoing insomnia or sleep apnea, can contribute to depression and make it more resistant to treatment. Sleep apnea is a condition that causes snoring, interrupted breathing and fragmented sleep. The person will not remember these nighttime struggles. The disorder can be treated.
Alcohol use or abuse can cause the fatigue and fuzzy-headedness of depression. And an underlying cause of alcohol abuse can be depression.
Some chronic infections (e.g. Hepatis B or C) or malignancies (including Hodgkin’s lymphoma) can also cause the type of fatigue and lethargy typical of depression
Stroke and Parkinson’s Disease can cause symptoms typical of depression
Some medications can cause depression symptoms:
- Oral steroids, such as Prednisone, often taken for asthma or joint pain
- Hormones, such as progesterone and estrogen
- Pain medications, such as Percocet
- Tranquilizers, such as Valium and Xanax
- Most blood pressure medications
- Prescription antianxiety medications known as benzodiazepines
- Heart medications, such as digitoxin (Crystodigin) and digoxin (Lanoxin)
- Over-the-counter nighttime cold remedies
If you’re being evaluated by your primary care physician or a psychiatrist for what you think might be depression, be sure to discuss all your symptoms, especially physical ones, even if you don’t think they’re related. And, don’t forget to tell him or her what medications you’re taking.
