Depression is a medical condition that shows its symptoms through your mood and functionality. If you have depression, you may feel sad, anxious, or hopeless. There can be a spectrum of diagnoses for depression and how severe it can be. Depression is a severe condition and, left untreated, can lead to dire consequences.

What causes depression?

Depression is not a condition that has one specific cause. It can happen for many different reasons and have many triggers. Usually, depression doesn’t work quickly or suddenly. Instead, it develops over long periods of time and can lead to a “downward spiral.”

The four major causes of depression are:

  • 1. Family history. Though there are no specific genes that we can look at and trace to depression, if your family members have had depression, you are more likely also to experience depression. The jury is still out on whether or not this link is due to learned behavior or biology. 
  • 2. Illness and health issues. Physical illnesses or injuries can have a significant impact on your mental health. Chronic health issues, long-term health issues, or physical health issues that drastically change your lifestyle can cause depression. Often, your doctors will understand this and may even offer mental health treatment as a part of your overall treatment. Issues connected to your brain, hormones, menstrual cycle or menopause, low blood sugar, or sleep problems can be very impactful. 
  • 3. Medication, drugs, and alcohol. Many different medications can have the unfortunate side effect of depression. If you feel depressed after starting a new medicine or medication, you should research its side effects or talk to your doctor. There could be a better alternative they could give you. Additionally, recreational drugs and alcohol use can also cause or worsen depression. While they may initially feel like they help symptoms of depression, they will make you feel worse eventually.
  • 4. Personality. Some people and personalities are just more apt to experience depression. For example, people who tend to hold in worries and stress, have low self-esteem, are perfectionists, and are sensitive to criticism are naturally more likely to be depressed.

Additional causes of depression

In addition to those causes, two of the more abstract causes of depression can be:

Life Events

It has been found through research that life events can increase your chances of being depressed. Examples of events like this include:

  • Losing your job
  • Being in a dysfunctional relationship
  • Stress at work
  • Isolation
  • Going through a breakup or divorce
  • Being diagnosed with an illness
  • Being unemployed for a long time
  • Grieving a loved one

While negative life events can cause depression, they don’t necessarily always cause it. Often, it is more about how you deal with these difficult situations. Feeling down most of the time can lead to depression.

Chemicals in the Brain

Brain chemistry is a vastly complex and developing field of medical study. There is much that is still being researched. In addition, there are so many other factors besides simple brain chemistry that can lead to depression. Therefore, depression is not merely caused by a lack of certain chemicals. However, there are specific processes between nerve cells that can contribute to depression.

Treatments for depression

Many of the medications used to treat depression target the brain’s messaging centers. Some stimulate serotonin or noradrenaline production. In addition, some treatments like transcranial magnetic stimulation(TMS) or electroconvulsive therapy(ECT) are used to treat depression because they also target the brain’s messaging processes. However, these types of treatments are only used when therapy, lifestyle changes, social change, and medication have not helped.

A more definitive list of treatments for depression is:

  • Self-guided changes to your lifestyle. Simply changing things like your sleep cycle, how you spend your time, and other daily habits can do a lot to improve your depression.
  • Therapy. Beginning counseling, therapy, or psychotherapy with a mental health provider can help you better cope with your feelings and talk them through. You can do therapy for a short time or stay in it for more extended periods of time.
  • Alternative therapies. Many people with mild depression can heighten their therapeutic experience by supplementing it with acupuncture, hypnosis, or biofeedback.
  • Brain stimulation. For people who suffer from severe depression or psychosis, brain stimulation can be beneficial. As mentioned before, ECT or TMS are commonly prescribed. However, you can also try vagus nerve stimulation(VNS).

Of course, every person’s depression is unique to them. Because there is a broad spectrum for how depression can appear, the treatments can also vary. Just know that there is also a wide spectrum for treatment and that it may take some time for you to find the right one for you.
