Bad moods, good moods, sadness, cheerfulness — they’re all a part of life, and they come and go. But if your mood gets in the way of doing daily activities, or if you seem emotionally stuck, you may have depression or post-traumatic stress disorder (PTSD).

Both depression and PTSD can affect your mood, interests, energy levels, and emotions. Yet, they’re caused by different things.

It is possible to have both of these conditions at once. In fact, your risk for having one increases if you have the other.

Read on to learn more about PTSD and depression, how they’re alike, and how they’re different.

Post-traumatic stress disorder (PTSD) is a trauma and stressor-related disorder that can develop after a traumatic or stressful event.

This can occur after witnessing or experiencing a disturbing event, including physical or sexual assault, natural disaster, war, accidents, and domestic violence.

Symptoms of PTSD don’t typically show up immediately after the event. Instead, they may appear several weeks or months later, after any physical scars have likely healed.

common ptsd symptoms
  • Re-experiencing memories. This may include flashbacks or intrusive memories about the event, nightmares, and unwanted memories.
  • Avoidance. You may try to keep from talking or thinking about the event. To do this, you may avoid people, places, or events that remind you of the stressor.
  • Mood swings and negative thoughts. Moods change regularly, but if you have PTSD, you may feel down, numb, and hopeless frequently. You may also be hard on yourself, with a great deal of guilt or self-loathing. You might also feel detached from other people, including friends and family. This can make PTSD symptoms worse.
  • Changes in behaviors and reactions. PTSD can cause unusual emotional outbursts, like being easily startled or frightened, angry, or irrational. It may also cause people to act in ways that are self-destructive. This includes speeding, using drugs, or drinking too much alcohol.

PTSD can be diagnosed by your primary care provider or a mental health professional. Your primary care provider will begin with a physical exam to be sure that your symptoms aren’t being caused by a physical illness.

Once a physical issue has been ruled out, they may refer you to a mental health professional for further evaluation. Your doctor may diagnose PTSD if you’ve experienced symptoms of the disorder for more than four weeks and have a difficult time completing daily tasks because of your distress and emotions.

Some doctors will refer individuals with PTSD to a mental health specialist. These trained healthcare providers include psychiatrists, psychologists, and counselors. They can help you find treatment.

Depression is a chronic mood disorder. It’s more intense and lasts longer than just a day of sadness or “the blues.” Indeed, depression can have a significant impact on both your health and your well-being.

Your doctor may diagnose depression if you have five or more symptoms for at least two weeks straight.

symptoms of depression

Like PTSD, your doctor will likely be able to diagnose you after a physical exam and mental health exam to rule out any other possible causes.

Your healthcare provider may choose to treat you, or they may refer you to a mental health specialist.

It is possible to have both PTSD and depression simultaneously. They’re frequently confused for one another because of similar symptoms.

symptoms of both ptsd and depression

PTSD and depression can share these symptoms:

Research suggests people with PTSD are more likely to have depression. Likewise, individuals with depressive mood disorders are also more likely to experience more anxiety or stress.

Deciphering between unique symptoms can help you and your doctor find the right treatment.

For example, people with PTSD may have greater anxiety around specific people, places, or things. This is likely the result of the traumatic event.

Depression, on the other hand, may not be related to any issue or event that can be pinpointed. Yes, life events can make depression worse, but depression often occurs and worsens independently of any life events.

Traumatic events can lead to PTSD. The signs of this disorder typically show up several weeks after the distressing event. What’s more, depression can follow traumatic events, too.

Research suggests almost half of people who have or have had PTSD experience depression. Additionally, people who’ve had PTSD at some point in their lives are three to five times more likely to develop depression than individuals who didn’t experience PTSD.

People who have depression or a depressive disorder are also more likely to have symptoms of an anxiety disorder.

Though PTSD and depression are unique disorders, they may be treated in similar ways.

With both conditions, it’s important to seek treatment as soon as possible. Letting either condition linger — and likely worsen — for months or even years can do harm to both your physical and mental health.

As you can see, doctors use many of the same treatments for both PTSD and depression. This includes prescription medications, talk therapy, group therapy, and lifestyle improvements.
