Medical Causes of Depression

Depression is a mental health disorder that can cause significant impairment in daily functioning. The impact on mood can be substantial, and it can cause feelings of worthlessness and even suicidal thoughts and behavior.There are several causes of depression and various treatment options depending on the causes of depression and the symptoms presented. It is important to recognize depression so it can be treated immediately.

  1. Symptoms

    • Clinical depression is described as periods of sadness that last longer than two weeks and interfere with daily functioning. Additional symptoms like feelings of worthlessness, an inability to concentrate, changes in appetite or sleep patterns, difficulty concentrating and thoughts of suicide are all recognizable symptoms of clinical depression. A loss of pleasure in activities that once brought pleasure is also a symptom of depression.

    Biological Causes of Depression

    • There are various causes of depression. Physiological causes of depression such as chemical imbalances in the brain can lead to unstable mood and feelings of depression. According to the National Institute of Mental Health, research indicates that multiple chemicals are responsible for mood, and when these chemicals are out of balance there may be significant impairment in functioning. Chemicals such as serotonin, endorphins and dopamine work together to create our moods. An imbalance in these chemicals can cause symptoms like decreased self esteem, sadness and loss of pleasure.

    Environmental Cause of Depression

    • Depression can also be caused by environmental factors like the death of a loved one, divorce or the loss of a job. Events that trigger periods of sadness and create a void can often lead to feelings of depression. Significant impairment may lead to a decrease in activity and a loss of interest in daily functioning.

    Diagnosis

    • If depression symptoms exist it is important to get treatment as soon as possible. A counselor or physician can make a diagnosis of clinical depression and determine whether treatment is necessary. If depression is believed to be caused by biological factors, medication may be prescribed to help improve mood. Talk therapy may also be recommended if the causes are biological or environmental. Therapy can help address the issues causing the depression and be helpful in finding solutions.

    Education

    • Researching depression is an important part of successful treatment. There are numerous reliable websites (see Resources) that offer significant information about the diagnosis and treatment of depression. Ask questions when you see your physician and be sure you understand any medications prescribed.
