Brain structural changes in schizoaffective disorder compared to schizophrenia and bipolar disorder
On the other hand, the neuropsychological test results were nearly identical to that of Young and colleagues, indicating that poor performance on tests of frontal function predicted poor insight independent of other cognitive functions tested including IQ. This independent replication adds further evidence in support of the idea that poor insight into illness and resulting treatment refusal stem from a mental defect rather than defensiveness or informed choice.
Insight and Psychiatry, Vol. Unlike most studies of insight in the chronic mentally ill, this study evaluated patients when stabilized and enrolled in an outpatient work rehabilitation program. Patients with schizophrenia and schizoaffective disorder with poor insight had very poor adherence to the psychosocial treatment they had agreed to participate in despite a stated desire to work. Poorer insight was also correlated with lower scores on a test of frontal lobe function and with poorer performance on tests of other cognitive functions.
The authors conclude that individuals with schizophrenia and poor insight have more problems remaining in a course of treatment regardless of whether it is pharmacologic or a psychosocial treatment they had expressed a desire to participate in. These data, like that of Young et. Journal of Nervous and Mental Disease, 1 : Although symptoms of psychosis improved in nearly all of the patients over the course of the initial hospitalization, improvement in insight was seen only in those patients who had voluntarily agreed to being hospitalized.
Patients who had been involuntarily committed to the hospital did not show a similar improvement in level of insight into the illness. Furthermore, the low levels of insight persisted throughout the follow up period only in those patients who had been involuntarily admitted to the hospital. Not surprisingly, these same patients were more likely to be involuntarily committed over the course of follow up.
What is schizoaffective disorder?
The authors conclude that an inability to see oneself as ill seems to be a persistent trait in some patients with schizophrenia and one that leads to involuntary commitment. European Journal of Psychiatry, , Lack of insight into having an illness, defined by a single item on the Present State Examination, was correlated with structural brain abnormalities. Specifically, patients with poor insight into having an illness had increased ventricular brain rations. Ventricular enlargement of the third ventricle was most strongly correlated with poor insight.
Meanwhile, IQ was not found to be significantly associated with insight suggesting that the brain dysfunction underlying this deficit in self awareness may be relatively specific rather than a consequence of a general decline in cognitive function. This study is the first to show an association between structural brain abnormalities and lower levels of insight in patients with chronic schizophrenia. It adds to the growing body of literature that suggests that poor insight in this disorder is a consequence of a mental defect. This study reports on data that implicates frontal lobe dysfunction in the etiology of poor insight in patients with chronic schizophrenia.
Previous authors had hypothesized that frontal lobe pathology may account for the severe forms of unawareness frequently seen in certain psychotic disorders see recommended review article: Amador et al. Young and his colleagues tested this hypothesis using neuropsychological tests and the Scale to assess Unawareness of Mental Disorder.
The results indicated that poor performance on tests of frontal function predicted poor insight independent of other cognitive functions tested including IQ.
These results lend important support to the idea that poor insight into illness and resulting treatment refusal stem from a mental defect rather than informed choice. Journal of Nervous and Mental Disease, , Summarized by Dr. Xavier Amador.
This recent study of patients with schizophrenia, found, once again, strong correlations between various tests of frontal lobe function and level of insight. In this study bipolar patients were also examined using the same methodology, however no significant associations between the insight measure and tests of frontal lobe performance were found.
These results replicate previous findings that support the idea that poor insight into illness and resulting treatment refusal stem from a mental defect rather than informed choice in patients with schizophrenia. Schizophrenia Bulletin, , This paper reviews the extant literature on insight into illness in schizophrenia. The authors argue for a reassessment of the problem and consensus on terminology and measurement with the stated goal of stimulating scientific research.
Furthermore, they argue that poor insight in patients with schizophrenia may be due to brain dysfunction.
They point out numerous similarities between poor insight in patients with schizophrenia and anosognosia a neurological syndrome characterized by unawareness of illness in neurological patients. They conclude by offering guidelines for terminology and research. This paper reviews the literature on insight in affective psychoses. The authors remark that relatively little work has been done with this patient group when compared to patients with schizophrenia. Nevertheless, as in schizophrenia, studies of affective disorders find that lower levels of insight are correlated with a poorer course of illness, lack of adherence to treatment and involuntary hospitalizations.
The authors also conclude that level of insight is also a trait, unrelated to other signs of illness, in many patients. In this book the neurological basis of deficits in illness awareness is the focus of several chapters.

In addition, data indicating that lower levels of insight are associated with poorer illness course, increased exacerbations of illness, greater number and longer duration of hospitalizations and non adherence to treatment are reviewed. The role poor insight might play in violent behaviors is also discussed at length. Fuller Torrey SUMMARY: Impaired awareness of illness anosognosia is a major problem because it is the single largest reason why individuals with schizophrenia and bipolar disorder do not take their medications.
What is impaired awareness of illness? Is this a new problem? Is impaired awareness of illness the same thing as denial of illness? Can a person be partially aware of their illness?
What is schizoaffective disorder?
Why is impaired awareness of illness important in schizophrenia and bipolar disorder? Studies Correlating Anosognosia with Violence Lack of awareness of being ill is present in up to 50 percent of those with untreated schizophrenia and up to 40 percent of those with untreated bipolar disorder. Severity of community violence was strongly associated with poor insight, medication nonadherence, and substance abuse. The strongest predictors of violent behavior were lack of insight into symptoms especially delusions , being sicker, and past history of violence.
Twenty-two of them committed additional violent crimes, and eighteen did not. Lack of insight strongly correlated with higher levels of such behavior. The strongest predictors of violent behavior in the week following admission were poor insight and a past history of violence. Psychosocial Treatment Compliance in Schizophrenia.
