Frequently Asked Questions
What are the common symptoms of major depressive disorder that I should recognize?
Common symptoms include persistent sadness, loss of interest in activities, changes in sleep and appetite, fatigue, difficulty concentrating, feelings of worthlessness, and thoughts of death or suicide. These symptoms must last for at least two weeks for a clinical diagnosis.
What causes major depressive disorder and who is at higher risk for developing it?
Major depressive disorder can be caused by a combination of genetic, biological, environmental, and psychological factors. Those at higher risk include people with a family history of depression, individuals who have experienced trauma or chronic stress, and those with certain medical conditions or substance use disorders.
What treatment options are most effective for major depressive disorder?
The most effective treatments typically combine medication (such as antidepressants) with psychotherapy (like CBT or IPT). The specific combination varies by individual, and treatment plans are often personalized based on symptom severity and personal preferences.
How do antidepressant medications work, and what are their common side effects?
Antidepressants work by adjusting levels of neurotransmitters in the brain. Common side effects may include nausea, weight changes, sleep disturbances, and sexual dysfunction. These effects often improve over time, and different medications may be tried to find the best fit.
Can lifestyle changes and therapy alone help manage major depressive disorder without medication?
For mild to moderate depression, therapy and lifestyle changes may be sufficient for some individuals.
