Bipolar Psychosis and Unipolar Major Depression Disease
Bipolar psychosis during mania is common and yet not so much familiar to me until I started meeting more and more peers with BPD who have had or routinely have psychosis when manic. The facts in this post are dissected from Jamison and Goodwin’s “Manic-Depressive illness: Bipolar Disorders and Recurrent Depression, 2nd edition 2007, Oxford University Press.
Approximately 2/3 of people with BPD will have a manic psychosis in their lifetime. This is an average combining many clinical reports. The psychosis occurred mostly bipolar I patents. Some assert that manic syndrome is a psychotic disorder. From what I can read this is if one loosely defines the word psychosis.
Early onset BPD (adolescence) is more likely to be associated with manic psychosis. Some retrospective studies even suggest the psychosis in these young people is especially florid. I am getting ahead of myself here, but in patients whose first episode is major depression with a first manic episode several years later when further analyzed actually had had a psychotic depression. Another clinical study of manic psychosis found that those with this were at no higher risk of committing suicide Psychotic symptoms as in schizophrenia involve delusions and hallucinations. Delusions in a nut-shell are distortions of reality. This can be perception of self, such as feeling one is a religious figure or member of the CIA, or the environment such as paranoia, feeling all powerful, and having special powers. Hallucinations are visual, auditory or olfactory sensations that do not exist.
Since most manic episodes include “delusions” of grandeur or omnipotence then one could consider all manic episodes as psychotic.
As expected more florid delusions are found more likely in bipolar I than bipolar II patients. Religious themes were the most common delusion appearing in almost a third of psychotic episodes. Other psychotic delusions are political, sexual or financial.
Many studies show that hallucinations are much less common in manic phase or depressive phase of BPD. Delusions were found in up to 50% of people with BPD but only 10% have hallucinations. Auditory hallucinations are more common than visual.
One group found no distinct boundary between manic psychosis and mania alone. Since racing thoughts, forced speech, grandiosity, impaired judgment and necessity for sleep occurs in both bipolar II and I so in this manner all manic episodes have an element of psychosis.
Turning to bipolar depression the individual has the same myriad symptoms of MDD order. The occurrence of delusions or hallucinations defines psychotic depression. Delusional and hallucinatory behavior seem equal when present during psychotic depression. In its most severe state psychotic depression can involve delusions and hallucinations so severe that clouding of consciousness to the extent of stupor may occur. The individual loses all sense of self and environment. With medications and ECT now available the incidence of stupor approaching catonia is rare.
Bipolar depression with bipolar psychosis include delusions of guilt, sinful, impending poverty, and hypochondriac. A prominent delusion is the feeling that one is never going to get better and slip into “insanity”. As in psychotic mania delusions are more common than hallucinations. It is generally accepted that the individual with episodes of depressive psychosis will have the same delusions across separate episodes of depression.
Studies have also shown that bipolar depression is more likely to have psychotic features than major depression alone. People with psychotic bipolar depression are more likely to have a more severe course of bipolar disease and recurrent bipolar psychosis with subsequent episodes.
I will conclude with biochemical data found in “Decrease in Reelin and Glutamic Acid Decarboxylase67 (GAD67) Expression in Schizophrenia and Bipolar Disorder: A Postmortem Brain Study”, A. Guidotti, MD et al: Arch Gen Psychiatry2000;57(11):1061069.doi:10.1001/archpsyc.57.11.1061. “The selective-down-regulation of RELN and GAD67 in prefrontal cortex of patients with schizophrenia and bipolar disorder who have psychosis is consistent with the hypothesis that these parameters are vulnerability factors in psychosis.” I threw this reference in for fun. Now you know why I am not a scientist and chose to practice medicine than to do research in the “white palace,” academic institutions.
