Depression may be described as a mood disorder that affects the general outlook and mood of an individual. It is typically characterized by symptoms such as a sudden loss of general interest in most activities or a feeling of sadness or being down. Though it is the case that a lot of people may generally be sad or feel down for short periods of time, clinical depression is a lot more than just a feeling of sadness.

Depression is not a condition to be taken lightly as it is a serious condition. People who face depression are unable to get over their state of depression just like that. Depression if left untreated can lead to other certain issues like:

  • Alcohol and drug abuse
  • Issues with employability
  • Strained interpersonal relationships

Depression is a condition that is quite common. According to the Centers for Disease Control and Prevention, it is estimated that about 8.1% of American adults above the age of 20 had experienced depression within any given period of 2 weeks between the years 2013 to 2016.

Most of the people who get treated for their depression eventually go on with living their lives happily and healthily. For quite a few, their depression may turn out to be challenge that may last a lifetime and will require long-term treatment measures.

Contact a medical professional or mental health specialist if you think you may be experiencing depression or any other mood disorders. Depression is a condition that can be exhibited by persons of any age and gender.

What Causes Depression?

Depression is not a condition that has exact known causes. While some persons may be more prone to having depressive episodes, other people are not. This makes it necessary to discuss all symptoms you may be experiencing with your therapist or doctor. That being said, there are several potential factors that may cause depression.

Genetics

Depression may be a condition that is inherited. An individual has increased chances of experiencing depressive disorders at a point in their life if they have a close family member who experiences depression. The precise genes that are responsible for this have not been identified yet. Though there is the belief that several genes may play a role in the determination of whether a person is likely to experience depression.

Biochemical

There are some people experiencing depression who have shown changes around their brains that are noticeable. Despite the fact that not much is understood about this potential cause, those changes suggest that brain function could be a factor that influences depression. Some psychiatrists have studied the brain chemistry of people who have cases of depression.

Serotonin, norepinephine and dopamine which are all neurotransmitters within the brain are capable of affecting how an individual experiences pleasure and happiness and there is the possibility that it may be imbalanced in persons who are experiencing depression. Antidepressants counter this effect by restoring balance to the neurotransmitters, specifically serotonin. The reason these neurotransmitters get imbalanced, how they get imbalanced and the part they play in affecting depressive states is not still totally clear. 

Hormones

Changes in the production or functioning of hormones may cause the onslaught of depressive episodes. Any sort of changes in the hormonal balance such as childbirth, thyroid problems, menopause or some other disorders, may affect the likelihood of a person getting depressed.

In the case of postpartum depression, after they have given birth, some mothers may begin to develop certain symptoms. It is normal for most mothers to get emotional as a result of the changes in hormonal balance, but a condition like postpartum depression is a serious one.

Personality

Some persons have an increased likelihood of getting depressed and this may be as a result of their personality type. They might be persons who have serious tendencies to worry too much, persons who have a low self-esteem, persons that are very sensitive to criticism, especially when it is personal, people who are perfectionists or people who are usually negative and self-critical.

Seasons

As the daylight hours begin to get shorter as the winter approaches, a lot of people may begin to develop certain feelings of tiredness, lethargy and a possible loss of interest in daily activities. This condition used to be referred to as Seasonal Affective Disorder. More recently, it has come to be regarded as a major depressive disorder that occurs with a seasonal pattern.

It has been discovered that this condition may arise as a result of disruption in the normal pattern of the body’s circadian rhythm. Aside from this, a reduction in sunlight may cause the level of serotonin in the brain to drop, which may affect a person’s mood.

Your doctor or therapist may recommend medication or the use of a light box to ease the condition. Usually, the condition begins to go away gradually once the daylight hours get longer.

Situations

Traumatic events, very significant changes or life struggles are likely to lead to depression in a person. The death of a loved one, the loss of one’s job, financial difficulties or significant changes in a person’s life may have a huge toll on people.

Generally, stressful events are capable of overwhelming a person and may cause them to experience depressive episodes.

It is suspected that increased levels of cortisol, a stress hormone, affect the level of serotonin in the brain and may increase the likelihood of a person getting depressed.

Substance Use

The use of alcohol and drugs may increase the likelihood of depressive disorders. About 21% of persons that have issues with substance use may also experience depression.

There are even certain prescription drugs that have been noticed to have similar effect.
