The researchers next compared subjects who did convert with those who did not in order to find characteristics which might serve as predictors of the transition. They found seven notable factors after repeated logistic regression analyses: earlier onset age, recurring depression, solitary living conditions, collecting disability income, never exceeding a technical level education, short-term higher education and medium-term higher education.
The other interesting finding from this study was that the conversion from one illness to the other does not appear to be related to how long a person has been medicated for their psychotic depression. Expressed as an adjusted odds ratio AOR , the researchers compared the likelihood of persons in certain age brackets converting to bipolar disorder compared to a person whose psychotic depression began on or before the age of 20 years:. The study discovered a conversion rate that was lower than other researchers had identified in previous long-term studies.
The Danish researchers say the difference may be due to methodological issues. Skip to content. Create a personalised ads profile. Select personalised ads.

Psychosis, which includes hallucinations and delusions, is a hallmark symptom of schizophrenia. So while bipolar disorder and schizophrenia can share a set of serious symptoms, when distinguishing between the two disorders, doctors look at the differences between symptoms and also give different weight to some of the shared symptoms.
For most of a month, a patient must have two of these symptoms:. If only one of these symptoms is present, one of the following must also appear:. At the same time, there's a marked decrease in at least one important area of functioning, such as:. In addition to the month of acute symptoms, the overall disturbance must have persisted for at least six months. None of the symptoms of delusions, hallucinations, and disorganized speech and behavior have to be present for someone to be diagnosed with bipolar disorder, although they may be present.
In fact, the only requirement for a diagnosis of bipolar I disorder is that the patient has had one manic episode ; though depression is also common, it isn't required for a diagnosis. Depressive episodes cause persistent feelings of sadness and loss of interest in activities. Manic episodes cause euphoria, increased energy and activity, and lack of sleep.
Psychotic episodes may occur during depression or mania and can cause a person to become delusional or to hallucinate. Bipolar disorder , which was previously called manic depression, is a mood disorder that causes episodes , lasting a couple of weeks or longer, of depression or mania, and sometimes psychosis. For instance, a person with bipolar disorder may have a great life with a loving family and a nice job, but during a depressive episode cannot shake the feeling that he or she is worthless.
These abnormal moods usually shift between depression and mania, the latter being the opposite of depression but just as destructive and unhealthy. In severe instances, some people will also go through episodes of psychosis in which they lose touch with reality and may hallucinate or have disturbing delusions. These mood episodes can be very damaging, but they are fortunately manageable with appropriate treatment.
Bipolar depression episodes are very similar to episodes of major depression. The main factor that separates these two conditions is the presence of manic episodes. Just one episode of mania is enough to make the diagnosis bipolar disorder rather than major depression. But, when someone is going through bipolar depression, it looks and feels very much like major depression. Symptoms include:. Bipolar depressive episodes may cause all of these symptoms or just a handful.
Each person experiences and expresses depression in a slightly different way, but there are many commonalities. To be considered a depressive episode, a person must have at least five of the common symptoms and these must persist and be significantly disruptive for two weeks or more. One of the five symptoms must be depressed mood or loss of interest in activities. Mania, or the less severe hypomania, must have occurred at least once for a person to be diagnosed with bipolar disorder.
The mood may shift between irritability and euphoria several times. Symptoms of mania include:. To be diagnosed as having had a manic episode, a person must have experienced at least three of the symptoms. The symptoms have to persist for at least a week and cause significant distress or impairment. There is more than one type of bipolar disorder, and the type referred to as bipolar II causes episodes of hypomania rather than mania.
Hypomania causes any of the same symptoms as mania, but is less intense and less severe. We've got answers for you. Mania and hypomania are both symptoms of bipolar disorder.
