How Are Anxiety and Mood Disorders Connected?

Anxiety and mood disorders are closely connected: they often occur in the same person, share symptoms such as poor sleep, irritability and trouble concentrating, and can make each other worse. Because they overlap, a careful evaluation matters. Treating only one condition can leave the other active, while a plan that addresses both tends to work better.

This article is for adults who have been told they have anxiety, depression or bipolar disorder and suspect something else is going on, and for families trying to make sense of a loved one's symptoms. This article is general information, not a medical recommendation. Do not start, stop or change any medication without talking to your prescriber.

What are anxiety disorders and mood disorders?

Anxiety disorders involve fear or worry that is excessive, lasting and hard to control, while mood disorders involve ongoing changes in your emotional state, such as depression or the highs and lows of bipolar disorder. MedlinePlus explains that anxiety becomes a disorder when the fear is not temporary and can be overwhelming.

MedlinePlus also describes a mood disorder as a condition that affects your everyday emotional state. Common examples include:

• Anxiety disorders: generalized anxiety disorder (GAD), panic disorder and social anxiety disorder.
• Mood disorders: major depression, persistent depressive disorder and bipolar disorder.

Can you have anxiety and depression at the same time?

Yes, many people have an anxiety disorder and a mood disorder at the same time. The National Institute of Mental Health (NIMH) notes that some people with GAD have other mental and physical health conditions, including depression, and that having more than one condition can make treatment more complex.

NIMH's depression booklet also notes that young adults with depression often have other disorders, such as generalized anxiety disorder, social phobia or panic disorder. For a side-by-side comparison, see anxiety vs. depression.

Which symptoms overlap?

Anxiety and mood disorders share several symptoms, which is one reason they can be hard to tell apart. NIMH lists restlessness, fatigue, trouble concentrating, irritability, muscle tension and sleep problems among GAD symptoms, and many of these also appear in depression.

Shared symptoms often include:

• Trouble falling or staying asleep.
• Feeling tired or drained.
• Difficulty concentrating or making decisions.
• Irritability.
• Physical complaints such as headaches or aches.

Features that point more toward one or the other:

• More typical of anxiety: worry about what might happen, a sense of danger, feeling on edge, avoiding feared situations.
• More typical of depression: sadness or emptiness, loss of interest or pleasure, hopelessness, feeling worthless.
• More typical of bipolar disorder: periods of unusually high energy, little need for sleep and racing thoughts.

How can these conditions feed each other?

Anxiety and mood disorders can feed each other through sleep loss, avoidance and exhaustion. NIMH notes that depression can co-occur with other mental disorders and that each condition can make the other worse. A hypothetical example shows how the cycle can work:

1. Constant worry keeps someone awake at night.
2. Poor sleep drains energy and lowers mood.
3. Low mood makes it harder to face tasks, so they avoid them.
4. Avoided tasks pile up, which creates more worry.

Alcohol can deepen the cycle. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) notes that depression and anxiety commonly occur with alcohol use disorder. Breaking any one link in the chain, such as sleep or avoidance, can help the others improve.

Where does bipolar disorder fit in?

Bipolar disorder is a mood disorder that can also come with anxiety, and its depressive episodes can look like ordinary depression. NIMH describes bipolar disorder as causing clear shifts in mood, energy, activity levels and concentration.

This matters because anxiety or depression treatment may need to be adjusted if someone has a history of mania or hypomania. Tell your clinician about any past periods when you needed much less sleep, felt unusually confident or driven, or acted out of character. Our article on bipolar 2 vs. depression explains why this history is important.

How are overlapping conditions diagnosed?

A clinician diagnoses anxiety and mood disorders through a detailed conversation about symptoms, timing, history and daily impact, sometimes with questionnaires. NIMH advises people with panic symptoms to see a health care provider for an exam, because some physical conditions can cause similar symptoms.

The evaluation often looks at:

• Which symptoms came first and how they have changed.
• Whether symptoms happen in episodes or are constant.
• Any history of mania or hypomania.
• Sleep, alcohol and substance use.
• Medical conditions and medicines that could play a role.

How are both conditions treated?

Treatment for anxiety and mood disorders usually combines psychotherapy, medication or both, in a plan that addresses each condition. NIMH says GAD treatment typically involves psychotherapy, medication or both, and that cognitive behavioral therapy (CBT) is commonly used.

Common elements of care include:

• Therapy: CBT and related approaches teach skills for worry, avoidance and negative thinking.
• Medication: some medication classes are used for both anxiety and depression, while bipolar disorder often needs different medicines. Your prescriber explains options, benefits and side effects.
• Lifestyle supports: regular sleep, physical activity and reduced alcohol.
• Follow-up: NIMH notes that finding the right option may take trial and error.

What does the overlap look like in daily life?

In daily life, the overlap often looks like worry and low mood taking turns, or blending so that it is hard to name which one is in charge. MedlinePlus notes that anxiety can be a normal feeling that helps you cope, which is part of why people sometimes wait a long time before recognizing a disorder.

Hypothetical examples of how this can show up:

• Example 1: A college student has worried about grades for years. This semester, the worry is joined by skipping classes, sleeping until noon and no longer caring about friends.
• Example 2: A parent describes "just stress," but on closer questioning has felt empty most days for a month and has panic-like episodes before work.
• Example 3: An adult treated for anxiety notices that every few months they have a week of unusually high energy and very little sleep.

Each example would call for a different conversation with a clinician, which is why describing the pattern, not just the worst symptom, is so useful.

How can you support recovery at home?

You can support recovery at home by keeping sleep regular, gradually returning to avoided activities, and cutting back on alcohol. NIMH lists regular sleep and exercise among the habits that can support mental health alongside treatment.

• Keep the same wake time every day.
• Schedule one small, doable activity each day, even if motivation is low.
• Face one avoided task in small steps rather than all at once.
• Limit caffeine in the afternoon and alcohol in the evening.
• Tell one trusted person how you are really doing.

What should you tell your clinician?

You should tell your clinician about every symptom, even ones that seem unrelated, because overlap is common. NIMH recommends that you prepare a list of questions and be specific about symptoms before a visit.

A checklist to bring:

• Your top three symptoms and when each started.
• Whether worry or low mood came first.
• Any panic attacks, with what you felt in your body.
• Any periods of very high energy or little need for sleep.
• Alcohol, cannabis, caffeine and other substance use.
• Family history of anxiety, depression or bipolar disorder.

Example of what to say: "I have worried constantly for years, but in the past two months I have also stopped enjoying anything and I am sleeping badly."

When should you get help sooner?

You should seek help quickly if symptoms are getting worse, you cannot manage daily tasks, or you have thoughts of suicide. Red flags include:

• Thoughts of death, suicide or self-harm.
• Feeling hopeless or trapped.
• Frequent panic attacks or fear of leaving home.
• Several days with little sleep and unusually high energy.
• Drinking or using drugs more to cope.

NIMH advises calling or texting 988 for suicidal thoughts. Call 911 if there is immediate danger.

What should Texans know about getting evaluated?

Texans can seek an evaluation from a psychiatrist, psychiatric nurse practitioner, therapist or primary care provider, depending on the concern. Telehealth can make evaluation easier across large distances, but the U.S. Department of Health and Human Services notes that providers must be licensed or legally permitted to practice in the state where the patient is located, and rules vary by state.
