- The general public believe that depression is caused by both nature and nurture factors.
A majority of the public believed that nurture has a greater influence on whether the person gets depression or not.
Most likely, depression is caused by a combination of genetic, biological, environmental, and psychological factors, according to the NIMH.
Certain medical conditions may also trigger depression, including an underactive thyroid gland, cancer, heart disease, prolonged pain and other significant illnesses.
Less common treatments: For patients with severe depression who have not responded to any medication or psychotherapy, doctors may consider transcranial magnetic stimulation (TMS), according to the Mayo Clinic.
TMS involves receiving brief magnetic pulses on the scalp to stimulate nerve cells in the brain that are thought to be involved in mood regulation and depression.
This class of medication includes fluoxetine (commonly known as Prozac), sertraline (Zoloft), paroxetine (Paxil), escitalopram (Lexapro) and citalopram (Celexa).
Side effects, which are usually temporary, include changes in sexual desire, digestive problems, headache, insomnia and nervousness.
Different types of psychotherapy include cognitive-behavioral therapy, which helps a person change negative thought patterns and replace them with healthier ones, as well as interpersonal therapy, which is designed to help someone understand and work through difficult relationships, according to the National Institute of Mental Health.
Another form of psychotherapy is problem-solving therapy, which involves coming up with realistic solutions to cope with stressful situations.
