A recent article published in a leading psychiatry journal, JAMA Psychiatry, has shown that pregnant mothers’ exposure to the influenza (flu) was associated with a nearly 4X increase in risk to their child eventually developing bipolar disorder in adulthood. These findings add to mounting evidence of possible shared underlying causes and illness processes with schizophrenia, which some studies have also linked to prenatal exposure to influenza. Bipolar disorder, historically called manic depressive disorder, is a mood disorder where the sufferer can experience episodes of a frenzied state known as mania (or hypomania), typically alternating with episodes of depression. It can be treated with medications and psychotherapy (especially cognitive therapy), but more difficult cases require the individual to be voluntarily or involuntarily institutionalized until the mood changes can be reduced or eliminated.
As I’ve discussed previously, placebo effects are mostly a myth, and if a new drug has an effect barely above that of a mythical placebo effect, it’s considered a failure. In a recent article in Reuters Health, Rising placebo response seen in schizophrenia trials, Amy Norton states that clinical trials of anti-schizophrenia drugs, in a class of drugs called antipsychotics, are finding lesser effects because patients are responding positively to placebos (that presumably does not contain anything but sugar).
Treating schizophrenia or any psychosis is difficult because different patients respond in different ways to each drug. For some individuals, these drugs can treat many of the symptoms of schizophrenia, including hallucinations and delusions, which allows them to live relatively normal lives. But for some individuals these same drugs have significant side effects, including sedation, weight gain, and hyperglycemia (which can be serious for a diabetic). Eventually, individuals stop using the drugs because of the side effects and their psychotic symptoms return. Continue reading “Placebos cannot replace antipsychotics”
