Psychotic Depression

What Is Psychotic Depression?
Roughly 25% of people who are admitted to the hospital for depression suffer from what's called psychotic depression. In addition to the symptoms of depression, psychotic depression includes some features of psychosis -- like hallucinations (seeing or hearing things that aren't really there) or delusions (irrational thoughts and fears).
How Is Psychotic Depression Different Than Other Mental Illness?
While people with other mental illness, like schizophrenia, also experience these symptoms, those with psychotic depression are usually aware that these thoughts aren't true. They may be ashamed or embarrassed and try to hide them, sometimes making this type of depression difficult to diagnose. Having an episode of psychotic depression increases your risk of bipolar depression, recurring episodes of psychotic depression, and suicide.
What Are the Symptoms of Psychotic Depression?
Symptoms that occur commonly in psychotically depressed patients include:
Anxiety

Agitation

Hypochondria

Insomnia

Physical immobility

Constipation

Intellectual impairment

Psychosis

How Is Psychotic Depression Treated?
Treatment for psychotic depression requires a longer hospital stay and close follow-up by a mental health professional. Combinations of antidepressants and antipsychotic medications have been most effective in easing symptoms. Electroconvulsive therapy (ECT) may also be used to treat psychotic depression.
What Is the Outlook for People With Psychotic Depression?
Treatment is very effective for psychotic depression, and people are able to recover, usually within a year, but continual medical follow-up may be necessary. It is important, however, that a person experiencing these symptoms be properly diagnosed because treatment is different than for other major depressive illnesses and risk of suicide is greater.

Roughly 25 percent of people who are admitted to the hospital for depression suffer from psychotic depression. Psychotic depression is characterized by not only depressive symptoms, but also by hallucinations (seeing or hearing things that aren't really there) or delusions (irrational thoughts and fears). Often psychotically depressed people become paranoid or come to believe that their thoughts are not their own (thought insertion) or that others can ‘hear’ their thoughts (thought broadcasting).
While people with other mental illness, like schizophrenia also experience these symptoms, those with psychotic depression are usually aware that these thoughts aren’t true. They may be ashamed or embarrassed and try to hide them, sometimes making this variation difficult to diagnose. Risk of bipolar depression, recurring episodes of psychotic depression and suicide are increased after its onset.
Researchers aren't exactly sure what causes major depressive disorder with psychotic features (psychotic depression), but it's frequently associated with high levels in the blood of a hormone called cortisol ( Cortisol is an important steroid hormone produced by the adrenal glands. The blood levels of this hormone typically follow a pattern throughout the day, with the lowest levels occurring around 4 in the afternoon. More cortisol is released during times of stress -- biological and psychological).
There are no obvious risk factors, though it is known that those with a family history of depression or psychotic illness will be more susceptible.
