In the West London first-episode study of schizophrenia, Barnes et al. It's impossible to separate the physical brain from the neurochemicals in the brain, but there are actually structural differences in the brain of people who experience psychosis. Clipboard, Search History, and several other advanced features are temporarily unavailable. Barnes TR, Hutton SB, Chapman MJ, Mutsatsa S, Puri BK, Joyce EM: West London first-episode study of schizophrenia: clinical correlates of duration of untreated psychosis. The neurotoxicity postulated to arise through these biological mechanisms would, in turn, lead to impaired functioning and worsen outcome in schizophrenia. In general, there was paucity of statistically significant differences between groups with short or long duration of untreated initial psychosis with regard to cognitive deficits and brain measures (Table 1 and Table 2). RESULTS: Shorter duration of untreated psychosis was associated with greater response to antipsychotic treatment, as measured by severity of global psychopathology, positive symptoms, negative symptoms, and functional outcomes. Several studies have shown meanDUPs of 1 year or more. The duration of untreated initial psychosis, as it is retrospectively assessed, is subject to recall bias.

In line with the hypothesis of a “neurotoxicity” of untreated psychosis, it might be surmised that the longer such processes/symptoms and psychological distress persist, the more pronounced structural alterations of HV and PV could be. These two statistically significant associations could also have been type I errors. Thirteen subjects did not have scans at intake. Being in the midst of their first episode of psychosis, the subjects were moderately ill (negative symptom severity [sum of global ratings for alogia, anhedonia, avolition, and affective flattening]: mean=11.53, SD=3.56; psychotic symptom severity [sum of global ratings for delusions and hallucinations]: mean=6.45, SD=2.41; disorganized symptom severity [sum of global ratings for disorganized behavior, positive formal thought disorder, and inappropriate affect]: mean=5.49, SD=2.60). 5, Schizophrenia Research, Vol. Spearman’s partial correlation coefficients were used to examine the relationships between duration of untreated initial psychosis and the MRI-based brain morphology measurements.

In addition to brain volumetric measures, Hoff et al. If such pathogenic processes are also present around the onset of clinical symptoms, it appears that untreated psychosis is not a contributing factor. With these z scores, each domain score is the summed average of its component neuropsychological test variables (Appendix 1). Epidemiological studies, mirror-image studies, and early antipsychotic treatment trials have been cited as supportive of this “toxic psychosis” hypothesis (5).

Miller TJ, McGlashan TH: Early identification and intervention in psychotic illness. In this current study, which has the largest group of first-episode subjects collected to date to our knowledge, we examined whether untreated psychosis has toxic effects on brain tissue and function using the tools of anatomic magnetic resonance imaging (MRI) and tests of cognition. The more time passes between the first psychosis symptoms and adequate treatment, the poorer the prognosis. In this current study, which has the largest group of first-episode subjects collected to date to our knowledge, we examined whether untreated psychosis has toxic effects on brain tissue and function using the tools of anatomic magnetic resonance imaging (MRI) and tests of cognition.

Equivocal evidence exists of an association between DUP/DUI and structural brain abnormalities, such as reduced hippocampus volume (HV), pituitary volume … This duration of untreated initial psychosis usually averages between 1 and 2 years. However, there are other possible interpretations for these two significant associations (4, 44). 4,5 When FEP goes untreated, approximately 10 to 12 cc of brain tissue—basically a tablespoon of cells and myelin—could be permanently damaged.

The objective was to determine the effects of DUP on functional connectivity and brain morphology measured with resting-state functional and structural magnetic resonance imaging. This reason alone justifies efforts to reduce treatment delays, irrespective of whether early intervention improves outcome or whether untreated psychosis is neurotoxic. 4, General Hospital Psychiatry, Vol. However, Dr. Nasrallah explained, science already has demonstrated how the neurotoxic effects of psychosis in the brain of a person with schizophrenia lead to brain tissue degradation with every psychotic episode. 44, No. None of the correlation coefficients achieved statistical significance. Besides biological toxicity, prolonged duration of untreated initial psychosis may impair subsequent outcome through psychosocial factors, such as missed educational and employment opportunities, devastation of self-esteem, and reduction in the psychosocial support network. Intracranial volume was divided into brain tissue and CSF. 1, British Journal of Psychiatry, Vol. Andreasen NC: Scale for the Assessment of Negative Symptoms (SANS). Measurements included nine domains of neurocognitive functioning, volumetric measures of total brain tissue, gray and white matter, and CSF, and measures of brain surface anatomy. Duration of untreated psychosis is associated with orbital-frontal grey matter volume reductions in first episode psychosis. In this study, we examined the relationship between duration of untreated initial psychosis and neurocognitive functioning and brain morphology, as assessed when patients with schizophrenia first presented for treatment. 2-3, Schizophrenia Research, Vol. But researchers are still pursuing a better understanding of the neurological impact of psychotic episodes.

Although there are presently still more publications in the literature reporting on the association between long duration of untreated initial psychosis and poor outcome (7–16), an increasing number of studies published during the past 3 years have failed to find this association (17–22). The time period during which patients manifest psychotic or unspecific symptoms prior to treatment (duration of untreated psychosis, DUP, and the duration of untreated illness, DUI) has been found to be moderately associated with poor clinical and social outcome. 288, Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, Vol. Previous structural MRI studies have explored the effect of antipsychotics, the treatment most commonly used in psychosis, on the brain. 5, Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, Vol. The period from the onset of frank psychotic symptoms to the start ofadequate treatment, the duration of untreated psychosis (DUP), varies considerablyin patients with first-episode psychosis. Such lengthy delays are undesirable, since deferring effective treatments leads to unnecessary and undue suffering for both patients and their families. 146, No. Correlations between neurocognitive functioning, brain volumetric measurements, and surface anatomy measurements with duration of untreated initial psychosis were weak; none reached statistical significance. Wilcoxon’s rank sum test was used to compare differences in neurocognitive functioning between groups with short and long duration of untreated initial psychosis. While all studies assume psychosis to be persistent from onset, this may not apply for all patients, especially those with a long duration of untreated initial psychosis, in which there may have been spontaneous remissions. Some studies have found long duration of untreated initial psychosis to be associated with poorer outcome (7–16), while others have not (17–22). A total of 156 subjects (97 male and 59 female) were evaluated during their first episode of psychotic illness at the University of Iowa’s Mental Health Clinical Research Center. (19) also examined the correlations between duration of untreated initial psychosis and seven summary scores from a neurocognitive battery. 164, No. Previous studies have also failed to find significant associations between duration of untreated initial psychosis and neurocognitive functioning at the time of first presentation for treatment. 200, No. The relation of the duration of untreated initial psychosis with the nine cognitive domains, the MRI-based brain volumetric measures, and the surface anatomy indices are summarized in Table 1 and Table 2.
