Do You Have Depression?
Depression is a common mood disorder that affects around 280 million people worldwide.
Have you been feeling sad, hopeless, or low-energy? Have you had difficulty sleeping or concentrating? While these are common symptoms of depression, they could be a sign of something else. Health issues like vitamin D deficiency, anemia, or an undiagnosed condition such as autism can look a lot like depression. Learn how to better understand your symptoms.
Chronic Fatigue Syndrome (ME/CFS)
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and depression can both leave you exhausted and struggling to concentrate. Other common symptoms of ME/CFS include dizziness, muscle and joint pain, and headaches.
ME/CFS typically affects young and middle-aged adults, with women diagnosed more often than men.
Fibromyalgia
Fibromyalgia is often misdiagnosed as depression because depression can be a symptom of fibromyalgia. This musculoskeletal disorder causes your brain and spinal cord to process pain signals with more intensity. Women are at a higher risk than men.
Other symptoms of both fibromyalgia and depression include:
Sleeping problems
Trouble with memory and concentration
Fatigue
Difficulty sleeping
Lyme Disease
Lyme disease is called the “great imitator” because it shares symptoms with so many other conditions. Lyme disease can cause overwhelming fatigue and cognitive symptoms that can look like depression. Other symptoms include headaches, fevers, and a skin rash called erythema migrans. This rash appears as a distinctive bullseye shape.
If you’ve recently been bitten by a tick — or in an area with a heavy tick population, including states like Minnesota and Maryland — you may want to check with your doctor about testing for Lyme disease.
Hypothyroidism
Like depression, hypothyroidism — a condition in which your thyroid doesn't produce enough hormones — can cause fatigue, weight gain, and memory problems. Depression itself can be a symptom of hypothyroidism.
Hypothyroidism can be diagnosed with a blood test and treated with synthetic thyroid hormones. Your risk is increased if you have a family history of hypothyroidism, are over 60, or have an autoimmune disease.
ADHD
ADHD is a neurodevelopmental disorder often related to high energy levels. However, many people with inattentive-type ADHD experience fatigue from trying to focus. ADHD symptoms that can be misinterpreted as depression include:
Lack of concentration
Difficulty at work or school
Mood swings
Low-stress tolerance
Ehlers-Danlos Syndrome (EDS)
Ehlers-Danlos Syndrome is a rare genetic connective tissue disease that can cause fatigue, brain fog, and sleep disturbances.
If you have stretchy or fragile skin, hyper-mobile joints, or bruise easily, you may want to ask your doctor about Ehlers-Danlos Syndrome.
Autism
8/1
Autism is a developmental disability that can be misdiagnosed as depression. Common symptoms include:
Nervousness about social interactions
Difficulty making friends
Social isolation
Avoiding eye contact
Misdiagnosis is widespread in women, who tend to hide autistic traits.
Vitamin D Deficiency
Many adults are low in vitamin D, which can cause symptoms like fatigue and mood changes that may look a lot like depression.
Vitamin D deficiency can be diagnosed with a blood test. If you’re obese, have a darker skin tone, or are over age 65, you may be at higher risk for low vitamin D.
Anemia
If you have anemia it means you don't have enough healthy blood cells to supply your body with enough oxygen. It can cause extreme fatigue, brain fog, and mood changes — all symptoms that are sometimes mistaken for those of depression.
Anemia can be diagnosed with a blood test. Treatment depends on the underlying cause but can be as simple as an iron supplement or dietary changes. People who menstruate, are pregnant, have chronic health conditions, or are over 65 are at a higher risk for anemia.
Bipolar Disorder
Bipolar disorder is a mental illness characterized by intense mood swings. Some people with bipolar disorder experience a less severe form of mania called hypomania, which can be misdiagnosed as depression.
Ask your doctor about screening for bipolar disorder if you experience:
Periods of mania or hypomania
Euphoria
Racing thoughts
Decreased need for sleep
Depressive symptoms
