Working With Patients With Impaired Insight

Introspective inference counteracts perceptual distortion

Introspective agents can recognize the extent to which their internal perceptual experiences deviate from the actual states of the external world. This ability, also known as insight, is critically required for reality testing and is impaired in psychosis, yet little is known about its cognitive underpinnings. We develop a Bayesian modeling framework and a psychophysics paradigm to quantitatively characterize this type of insight while people experience a motion after-effect illusion. People can incorporate knowledge about the illusion into their decisions when judging the actual direction of a motion stimulus, compensating for the illusion (and often overcompensating). Furthermore, confidence, reaction-time, and pupil-dilation data all show signatures consistent with inferential adjustments in the Bayesian insight model. Our results suggest that people can question the veracity of what they see by making insightful inferences that incorporate introspective knowledge about internal distortions.

Clinical insights: Preventing psychosis treatment disengagement

Many patients with schizophrenia spectrum disorders disengage from treatment, with negative impacts on prognosis and recovery. This commentary provides an overview of common reasons underlying treatment dropout and strategies for overcoming obstacles and enhancing patient engagement. Basic clinical skills such as open-ended questions and reflective listening can be powerful tools in unmasking structural and attitudinal barriers to psychosis care.

Meaning Analysis and Alienation: A Method of Immanent Critique in Acute Psychiatry

In acute psychiatry, where people with severe mental disorders are frequently treated, there can be contradictions between concepts of illness among, e.g., patients and healthcare professionals, and also between medical and legal aspects. These contradictions do not manifest themselves openly but are immanent in the social practices of the treatment teams as contradictions between the social level and the individual level. They can lead to alienation, which may be reflected in poorer quality of treatment, such as the more frequent use of coercive measures or poorer adherence to therapy in patients. In the normal daily routine of a clinic, these contradictions are mostly hidden by hierarchical structures or by unbalanced concepts of psychiatric illness, or external critique is used to try to solve these contradictions. However, another way of dealing with these contradictions could be to analyze the potential and causes for alienation through systematic analysis and transformation of the whole system of a psychiatric ward to reduce the level of contradiction within it. The aim of this work is to use the concept of meaning elaborated by Luhmann to identify and recognize alienation potentials as concretely as possible and thus make them accessible to immanent critique. Meaning in Luhmann's use of the term serves to reduce complexity in a social context and always opens up consequential possibilities for action. Consequential limited possibilities at the level of action in a rigid social system (which psychiatric wards can be) can-at an individual level-lead to people subordinating themselves to the rigid system to an excessive degree and thus alienating themselves from the system. Thus, a rigid system with a narrowing of consequential possibilities excludes meaningful consequential possibilities. This leads to alienating contradictions and to possibilities of world appropriation being missed. The aim of the current analysis is not to make a general critique of psychiatry but to improve the theoretical basis to better understand the problem of alienation in acute psychiatry as a symptom of system-immanent contradictions and thus open up the possibility of transforming systems, e.g., psychiatric acute care units, by means of immanent critique.

Antipsychotic utilization trajectories three years after initiating or reinitiating treatment of schizophrenia: A state sequence analysis approach

OBJECTIVE

This study aims to describe the utilization patterns of antipsychotic (AP) medication in patients with schizophrenia (SCZ), three years after initiating or reinitiating a given AP.

METHODS

Based on medico-administrative information on patients living in Quebec (Canada), this retrospective cohort study included 6444 patients with a previous diagnosis of SCZ initiating or reinitiating AP medication between January 1, 2012, and December 31, 2014, with continuous coverage by public drug insurance. For each day of follow-up (1092 days), patient was either exposed to one of the chosen categories of APs, or to none. This patient's sequence of AP exposure overtime has been referred to as the "antipsychotic utilization trajectory". These trajectories were analyzed using a State Sequence Analysis, an innovative approach which provides useful visual information on the continuation and discontinuation patterns of use over time.

RESULTS

Clozapine and long-acting injectable second-generation APs had the best continuation and discontinuation patterns over 3 years among all other groups, including less switching of APs, while oral first-generation APs had the poorest patterns. These findings were comparable among incident and non-incident cohorts. Oral second-generation antipsychotics, excluding clozapine, had a poorer continuation and discontinuation pattern than long-acting injectable antipsychotics.

CONCLUSION

State Sequence Analysis provides a clear representation of treatment adherence in comparison with dichotomous indicators of adherence or discontinuation. Consequently, this innovative method has shed light on the impact of the AP chosen to initiate or reinitiate treatment in SCZ, which has been identified as a key factor for long-term treatment continuation and discontinuation.
