Each person's recovery is different. Some recover in a few weeks or months. But for others, depression is a long-term illness. In about 20% to 30% of people who have an episode of depression, the symptoms don't entirely go away.
TRD Treatments Mirror Success Rates
Basically, 30% of people with depression are diagnosed with treatment-resistant depression.
It's estimated that 15% of the adult population will experience depression at some point in their lifetime.
The disorder isn't rare: Up to one-third of adults with major depression battle symptoms—such as persistent feelings of sadness, sleep disturbances, low energy and thoughts of death or suicide—that don't respond to treatment.
Persistent depressive disorder is a continuous, long-term form of depression. You may feel sad and empty, lose interest in daily activities and have trouble getting things done. You may also have low self-esteem, feel like a failure and feel hopeless.
For some people, depression might only be episodic and overcome within a matter of weeks or months. However, for others diagnosed with major depression , the condition could persist for years, affecting their lifestyle and quality of life.
In general, nearly everyone with depression has ongoing feelings of sadness, and may feel helpless, hopeless, and irritable. Without treatment, symptoms can last for many years. This condition is most often treated with medicine, therapy, or a combination of both.
Persistent depressive disorder, also known as dysthymia or chronic major depression, is a poorly understood condition for which the diagnostic criteria are constantly evolving. In the past, this condition was considered a personality disorder, which connotes a permanent, pervasive nature.
In their lifetimes, about one in five Australians will experience depression. Around the world, depression affects around 300 million people.
Women are more likely to have depression than men. An estimated 3.8% of the population experience depression, including 5% of adults (4% among men and 6% among women), and 5.7% of adults older than 60 years. Approximately 280 million people in the world have depression (1).
Depression is one of the most treatable mental health conditions. Approximately 80% to 90% of people with depression who seek treatment eventually respond well to treatment. Treatment options include: Psychotherapy: Psychotherapy (talk therapy) involves talking with a mental health professional.
Depression is among the most treatable of mental disorders. Between 80% and 90% percent of people with depression eventually respond well to treatment. Almost all patients gain some relief from their symptoms.
A major depressive disorder, TRD describes depression that has failed to respond to at least two different antidepressant treatments. Anyone who has experienced depression knows how inescapable and hopeless it can feel.
Although psychotic depression itself cannot evolve into schizophrenia, when severe depression is untreated or undertreated, it's possible for the resulting distress and side effects to trigger an underlying psychotic disorder, such as schizoaffective disorder.
Each person's recovery is different. Some recover in a few weeks or months. But for others, depression is a long-term illness. In about 20% to 30% of people who have an episode of depression, the symptoms don't entirely go away.
One may only speculate on depression rates in centuries past. Available epidemiologic evidence equivocally suggests that prevalence has risen over the past century, especially in recent decades, with younger cohorts exhibiting an earlier age-of-onset and increased lifetime risk.
Usually, the depressive episode length ranges from six months to eight months, depending on the person. While some people may have depression that fades, others may struggle with depression on and off their whole life. Also, different types of depression go away with time and are more short-lived by nature.
Clinical depression is a chronic condition, but it usually occurs in episodes, which can last several weeks or months. You'll likely have more than one episode in your lifetime. This is different from persistent depressive disorder, which is mild or moderate depression that lasts for at least two years.
Depression may cause the release of glucocorticoid in the brain, a type of steroid that can damage the hippocampus and other areas of the central nervous system. When this occurs, you may experience symptoms associated with neurocognitive disorder (dementia), such as memory loss.
Ongoing depression likely causes long-term changes to the brain, especially in the hippocampus. That might be why depression is so hard to treat in some people. But researchers also found less gray matter volume in people who were diagnosed with lifelong major depressive disorder but hadn't had depression in years.
Research suggests that depression doesn't spring from simply having too much or too little of certain brain chemicals. Rather, there are many possible causes of depression, including faulty mood regulation by the brain, genetic vulnerability, and stressful life events.
