Some people who have severe depression may also experience hallucinations and delusional thinking, the symptoms of psychosis. Depression with psychosis is known as psychotic depression.
Major depression is a serious mood disorder that causes a low mood, hopelessness, fatigue, and apathy, but in some cases it can also cause psychosis. Psychotic symptoms include delusions, hallucinations, and disordered thinking and speech.
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.
Major depression with psychotic features is a mental disorder in which a person has depression along with loss of touch with reality (psychosis).
A psychotic episode or disorder will result in the presence of one or more of the following five categories: delusions, hallucinations, disorganized thought, disorganized behavior, negative symptoms.
People who have psychotic episodes are often totally unaware their behaviour is in any way strange or that their delusions or hallucinations are not real. They may recognise delusional or bizarre behaviour in others, but lack the self-awareness to recognise it in themselves.
People with psychosis typically experience delusions (false beliefs, for example, that people on television are sending them special messages or that others are trying to hurt them) and hallucinations (seeing or hearing things that others do not, such as hearing voices telling them to do something or criticizing them).
Typically, a psychotic break indicates the first onset of psychotic symptoms for a person or the sudden onset of psychotic symptoms after a period of remission. Symptoms may include delusional thoughts and beliefs, auditory and visual hallucinations, and paranoia.
Someone experiencing mania will typically have upbeat hallucinations or delusions, while a person in a depressive state will have negative delusions. Because schizophrenia is not a mood disorder, a person with schizophrenia may not necessarily experience hallucinations and delusions that correlate with his or her mood.
The typical course of a psychotic episode can be thought of as having three phases: Prodrome Phase, Acute Phase, and Recovery Phase.
Signs of early or first-episode psychosis
Hearing, seeing, tasting or believing things that others don't. Persistent, unusual thoughts or beliefs that can't be set aside regardless of what others believe. Strong and inappropriate emotions or no emotions at all.
Psychotic disorders can last for a month or less and only occur once, or they can also last for six months or longer.
The types of delusions and hallucinations are often related to your depressed feelings. For example, some people may hear voices criticizing them, or telling them that they don't deserve to live. The person may develop false beliefs about their body, such as believing that they have cancer.
An episode of psychosis is treatable, and it is possible to recover. It is widely accepted that the earlier people get help the better the outcome. 25% of people who develop psychosis will never have another episode, another 50% may have more than one episode but will be able to live normal lives.
When a person is in a full-blown manic and psychotic episode, memory is greatly affected. In fact, it is rare for someone who is in a deep episode to remember all that happened. This is why it's called a blackout. The average person in this situation remembers maybe 50 percent, in my experience.
Anxiety-induced psychosis is typically triggered by an anxiety or panic attack, and lasts only as long as the attack itself. Psychosis triggered by psychotic disorders tends to come out of nowhere and last for longer periods of time.
Psychosis is often described as a "loss of reality" or a "break from reality" because you experience or believe things that aren't real. It can change the way you think, act, feel, or sense things. Psychosis can be very scary and confusing, and it can significantly disrupt your life.
Brief psychotic disorder is triggered by extreme stress, such as a traumatic accident or loss of a loved one. It is followed by a return to the previous level of function. The person may or may not be aware of the strange behavior. This condition most often affects people in their 20s, 30s, and 40s.
Brain changes can happen in people whose psychosis goes untreated. "The more relapses and episodes a person has, the more we see that it can permanently change their brain function and structure," says Tso.
There's no test to positively diagnose psychosis. However, your GP will ask about your symptoms and possible causes. For example, they may ask you: whether you're taking any medicines.
