Difference between Anxiety and Depression

Depression is a mood disorder that is more than just feeling down, experiencing the blues, or having a bad day. People who are clinically depressed have persistent sadness and loss of interest, lasting for several days, weeks, or even months. Depression can interfere with daily functioning and cause feelings of worthlessness and hopelessness. Some common forms of depression and depression-related conditions include:

1. Major Depressive Disorder (MDD): A mental health disorder characterized by persistent sadness and loss of interest in activities, interfering with daily life.
2. Psychotic Depression: A serious condition in which a person with depression experiences psychosis, showing symptoms like hallucinations and delusions. 
3. Postnatal Depression (PND): A mood disorder that occurs after childbirth. 
4. Atypical Depression: A subtype of major depressive disorder in which the person’s mood improves with a change in the circumstance.
5. Seasonal Affective Disorder (SAD): Depression that occurs at the same time every year.

However, healthcare professionals can diagnose anxiety disorders based on the definitions outlined in DSM-5. The diagnosis and treatment approach for both anxiety and depression is more or less similar. The following are the diagnosis, treatment, and complications of anxiety vs. depression.

Diagnosis

Doctors use several tools to diagnose anxiety and depression. The diagnosis for these mental health conditions includes:

1. Physical exam
2. Thorough understanding of your medical and mental health history

5. Comparison of symptoms with the criteria listed in DSM-5

Diagnosis of Anxiety vs. Depression As Per DSM-5

A doctor will diagnose anxiety or depression problems based on the criteria in DSM-5. 

1. Anxiety: A person has anxiety if they experience extreme, uncontrollable worry and three additional anxiety symptoms most days for at least six months. 
2. Depression: A person has depression if they experience at least five main depression symptoms on most days for at least two weeks. 

If they meet both criteria, the doctor will diagnose them with anxiety and depression.

The two primary treatments for anxiety and depression are medications and psychotherapy. Your doctor may recommend the following to treat anxiety vs. depression:

1. Medications: They can’t cure anxiety disorders but can improve the symptoms and help you function better. Medicines include:Anti-depressantsAnti-anxiety drugs, such as benzodiazepinesBeta-blockersSeveral anti-depressants can change the brain chemistry that causes anxiety or depression. These include:
         1. Selective Serotonin Reuptake inhibitors
         2. SerotoninNorepinephrine Reuptake Inhibitors (SNRIs), such as Effexor, Pristiq, etc. 
         3. Tricyclic anti-depressants
         4. Atypical anti-depressants

Generally, you cannot treat anxiety and depression alone. Most people with these disorders require medications and psychotherapy to get their symptoms under control. However, specific lifestyle changes can make a difference. These lifestyle changes or home remedies include:

Experiencing anxiety or depression is not something anyone wants. People with anxiety disorders or depression know the importance of preventing these conditions before they start interfering with a person’s daily life. While there is no certain way to prevent anxiety or depression, the following strategies may help:

1. Get help at the earliest sign of the condition to prevent it from worsening
2. Stay physically active and participate in activities that make you feel good
3. Avoid using alcohol and recreational drugs
4. Take steps to control stress, increase resilience, and boost self-esteem
5. Get enough sleep to make sure you are well rested
6. Eat a nutritious diet with colorful fruits, vegetables, nuts and seeds, whole grains, and fish
7. Limit sugar, caffeine, and processed foods

Now you know what’s the difference between anxiety and depression. But the question remains: Can you get both these conditions together? Yes, you can! Since both conditions involve the same neurotransmitters, such as serotonin, dopamine, and epinephrine, anxiety, and depression can develop sequentially or co-occur. One condition can easily trigger the other, with anxiety generally preceding depression. Symptoms that might indicate both anxiety and depression at the same time include:

1. Persisting irrational fears or worries
2. Physical symptoms like headaches, fatigue, rapid heartbeat, abdominal pain, etc. 
3. Difficulty sleeping
4. Eating too much or too little
5. Trouble concentrating or remembering
6. Constant sadness or feelings of worthlessness
7. Loss of interest in usual activities and hobbies
8. Inability to relax
9. Feeling tired and cranky most of the time
10. Losing a sense of internal control

Anxiety and depression can be highly uncomfortable. If not treated in time, the conditions can worsen to the point where patients have suicidal thoughts or attempt suicide. Therefore, it is essential to consult a mental health professional if you experience symptoms of anxiety or depression. Consult a doctor if:

1. Anxiety is harming your physical health.
2. You have anxiety about multiple areas, such as career, school performance, interpersonal relationships, etc. 
3. The symptoms begin interfering with your daily life.
4. You need to gain interest in most activities.
5. You feel sad and hopeless most of the time.
6. You need more energy on most days.
7. You are not able to sleep well.
8. You experience significant weight gain or loss without overeating or dieting.

Anxiety and depression are common mental conditions experienced by many. Even though people use these words as synonyms, there are some significant differences between anxiety and depression. While anxiety causes feelings of extreme fear and worry, depression involves feelings of despair and hopelessness. Both anxiety and depression can also occur at the same time. If you experience changes in your mood or other symptoms, do not hesitate to seek medical care.
