Clinical Depression - Causes, Symptoms, and Treatment

Introduction:

Depression is one of the most prevalent mental health illnesses. Unlike believed by many, depression is not imagined by the patient, and it is not in their control to get back up. Nor are they weak people who cannot boldly face the troubles of life. This is a misunderstanding. Clinical depression is an illness, a disorder. Depression works the same way as any other physical illness, say, ulcer, cancer, or tuberculosis. A person suffering from it cannot do much against it without proper attention and treatment from a psychiatrist.

What Is Clinical Depression?

Clinical depression is also called major depressive disorder. It is the most common form of depression. It is characterized by long-lived periods of persistent and intense grief. It has a severe impact on an individual's mood, behaviors, and physical functions like appetite and sleep. It is a chronic (long-lasting) disorder. However, the disorder will occur in episodes, each lasting for two weeks. Individuals will be diagnosed with this condition if they have the symptoms for two weeks.

Clinical depression is further classified into different types. Some of them are -

• Seasonal affective disorder (seasonal depression).

• Prenatal depression and postpartum depression.

• Atypical depression.

If you have clinical depression, then you have more chances of developing other disorders like -

• Substance use disorder (dual diagnosis).

• Panic disorder.

• Social anxiety disorder.

• Obsessive-compulsive disorder.

What Is the Difference Between Depression and Clinical Depression?

Clinical Depression vs Depression:Depression and clinical depression are two different things. Depression is just sadness, which everyone suffers from at some point, while clinical depression is a disorder or illness in which a person remains sad and despaired for an unreasonably long time. This condition hampers his daily activities as well as the people around him.

There are many symptoms that differentiate sadness from clinical depression. Some of the notable criteria are:

• The sadness lasts for more than two weeks.

• There is a lack of interest in the activities once enjoyed.

• Changes in sleep pattern and appetite.

• A sudden change in weight.

• A sudden outburst of emotions.

• Having suicidal thoughts or thinking of ways to harm themselves.

These are some of the notable criteria by which you can judge and differentiate between a person with mere sadness and a patient with clinical depression.

What Are the Types of Clinical Depression?

Clinical depression is an expansive term and covers many different types of depression. Doctors often use the term clinical depression for ‘major depression.’ Although there are many different types, none are as severe as major depression. Since many of their symptoms are common, they are grouped under the same disorder.

1. Major Depression:

Major depression is clinical depression. It is also known as “unipolar disorder.” The symptoms are the same as some of those mentioned above. It is the most severe type of depression. It occurs in episodes, which may be a single episode, twice, or several times in a person’s lifetime. It is believed to affect people below 40 to 45 years of age. It is severe enough to totally disturb and entangle one’s life and daily activities.

2. Dysthymic Disorder:

This is a less severe form of depression but involves long-term and chronic symptoms. Although it is a less severe form, it still prevents the patient from enjoying his or her life to the fullest. It prevents one from feeling good and acting to one’s full potential.

3. Bipolar Disorder:

Bipolar disorder is also known as manic depression. It consists of alternating periods of mania (elevation of mood) and depression. When the manic cycle goes up, a person feels over-energetic and talkative. It may increase their sexual activities with little or no sleep. At this stage, a person might feel that he has superpowers and can do anything, which may bring embarrassment and a lack of ability to work at full potential.

4. Seasonal Affective Disorder (SAD):

Seasonal affective disorder or SAD is a depression that directly relates to the weather and changes in weather and/or seasons or changes of seasons in a year, and/or brightness and duration of daylight. This sort of depression is often treated by artificial light therapy along with some medications.

5. Postpartum Depression:

New mothers affected by depression exhibit characteristics like loss of appetite, difficulty bonding with the child, anger, and frequent panic attacks. People affected by postpartum depression have a high chance of developing depression again in later stages of life.

• Brain Chemistry: An improper balance between neurotransmitters like serotonin, dopamine, and norepinephrine in the brain may cause this illness. Neurotransmitters are chemical substances that help transmit signals between neurons. Recent research suggests that fluctuations in neural circuits cause an imbalance in neurotransmitters.

• Hereditary: The risk of developing major depressive disorder runs in families. People whose blood relatives have this condition are more likely to get this disease. However, the gene responsible for causing depression is under research.

• Traumatic Events: You are at risk of developing depression if you suffer any crucial or stressful events in your life. It also depends on your financial status and the place you live.

How Is Clinical Depression Diagnosed?

Your symptoms, medical history, and family history of psychiatric illness assist the physician in diagnosing clinical depression. Also, physicians make use of clinical depression tests to evaluate you.

To confirm the diagnosis of clinical depression, you should have any five of the symptoms of clinical depression for at least two weeks. Of those five symptoms, two should be poor mood or sadness and lack of interest in activities that were once enjoyable. Based on your symptoms, the physician will be able to classify your depression as seasonal affective disorder, atypical disorder, or any other form of clinical depression.

To rule out other conditions, the physician may ask you to perform some laboratory investigations, like complete blood count. The physician also enquires whether you have had any hypomania or maniac episodes to rule out bipolar disorder. This is because individuals with clinical depression are more susceptible to bipolar disorder.

How Is Clinical Depression Treated?

Treatment for clinical depression includes the use of medications and psychotherapy. If used in combinations, they are more effective in treating the condition.

Psychotherapy is also called talk therapy. It involves talking with a therapist who would help you to navigate through negative emotions, thoughts, and behaviors.

There are various kinds of antidepressants. To determine which suits you best, it takes time. Also, antidepressants have various side effects, which will get better in some time.

In case of severe clinical depression, where medications and talk therapy do not work, electroconvulsive therapy is used.

However, it takes two to three months to get the complete benefits of medications. If you are not getting any improvement after two months, you should visit your physician so that your treating doctor will give you a different dosage or some other antidepressants.

In the case of talk therapy, you will feel some difference in your symptoms after a few weeks. Generally, it takes 15 or more sessions to notify you of any significant improvement in your symptoms.
