An individualised, non-pharmacological treatment strategy associated with an improvement in neuropsychiatric symptoms in a man with dementia living at home.

More than 90% of people with dementia experience neuropsychiatric symptoms which are often distressing and can result in early institutionalisation, diminished quality of life, increased frequency of emergency department visits along with stress and ill-health in caregivers. Non-pharmacological interventions are recommended as first-line treatment for neuropsychiatric symptoms, instead of medications such as atypical antipsychotics which have significant side effects. Most systematic reviews of non-pharmacological interventions for neuropsychiatric symptoms of dementia focus on patients in long-term care facilities and there are a limited number of research studies assessing the use of non-pharmacological interventions for patient's living at home. In this case report, we discuss an elderly man with dementia whose cognitive symptoms were accompanied by significant neuropsychiatric symptoms of suspicion, delusions, agitation and aggression. We describe how a programme of individualised, non-pharmacological interventions was associated with an improvement in neuropsychiatric symptoms within 3 months.

Acceptance and Efficacy of Metacognitive Training (MCT) on Positive Symptoms and Delusions in Patients With Schizophrenia: A Meta-analysis Taking Into Account Important Moderators.

Metacognitive training (MCT) is a new, widely used intervention for psychosis. The present meta-analysis examines the efficacy of MCT in schizophrenia. Fifteen studies comparing effects of MCT on positive symptoms, delusions or acceptance of MCT with a control group were included in this meta-analysis. These studies comprised a total of 408 patients in the MCT condition and 399 in the control condition. The moderating effects of masking of outcome assessment, randomization, incomplete outcome data, use of an active control intervention, and individual vs group MCT were investigated. Possible effects of sensitivity analyses and publication bias were also examined. The results show a significant overall effect of MCT for positive symptoms (g = -0.34, 95% CI [-0.53, -0.15]), delusions (g = -0.41, 95% CI [-0.74, -0.07]) and acceptance of the intervention (g = -0.84, 95% CI [-1.37, -0.31]). Using only studies being at low risk for bias regarding randomization, masking and incomplete outcome data reduced effect sizes for positive symptoms and delusions (g = -0.28, 95% CI [-0.50, -0.06] and g = -0.18, 95% CI [-0.43, 0.06]), respectively. This meta-analysis demonstrates that MCT exerts a small to moderate effect on delusions and positive symptoms and a large effect on acceptance of the intervention. The effect on delusions is reduced, but remains significant when potential biases are considered.

Brief culturally adapted CBT for psychosis (CaCBTp): A randomized controlled trial from a low income country.

Evidence for the effectiveness of Culturally adapted CBT for psychosis in Low And Middle Income Countries (LAMIC) is limited. Therefore, brief Culturally adapted CBT for psychosis (CaCBTp) targeted at symptoms of schizophrenia for outpatients plus treatment as usual (TAU) is compared with TAU. A total of 116 participants with schizophrenia were recruited from 2 hospitals in Karachi, Pakistan, and randomized into two groups with 1:1 allocation (CaCBTp plus TAU=59, TAU=57). A brief version of CaCBTp (6 individual sessions with the involvement of main carer, plus one session for the family) was provided over 4months. Psychopathology was measured using Positive and Negative Syndrome Scale of Schizophrenia (PANSS), Psychotic Symptom Rating Scales (PSYRATS), and the Schedule for Assessment of Insight (SAI) at baseline and end of therapy. Participants in treatment group, showed statistically significant improvement in all measures of psychopathology at the end of the study compared with control group. Participants in treatment group showed statistically significant improvement in Positive Symptoms (PANSS, Positive Symptoms Subscale; p=0.000), Negative Symptoms (PANSS, Negative Symptoms subscales; p=0.000), Delusions (PSYRATS, Delusions Subscale; p=0.000), Hallucinations (PSYRATS, Hallucination Subscale; p=0.000) and Insight (SAI; p=0.007). The results suggest that brief, Culturally adapted CBT for psychosis can be an effective treatment when provided in combination with TAU, for patients with schizophrenia in a LAMIC setting. This is the first trial of CBT for psychosis from outside the western world. These findings need replicating in other low and middle income countries.

Complementary group Metacognitive Training (MCT) reduces delusional ideation in schizophrenia.

BACKGROUND: Symptom reduction under antipsychotic agents is incomplete for most schizophrenia patients. In order to enhance outcome, cognitive approaches are increasingly adopted as add-on interventions. The present study aimed to determine the efficacy of group Metacognitive Training (MCT), which targets cognitive biases putatively involved in the pathogenesis of delusions. METHODS: A two-center, randomized, assessor-blind, controlled trial between MCT group training and cognitive training was carried out (ISRCTN95205723). A total of 150 in- and outpatients with DSM diagnoses of schizophrenia spectrum disorders were enrolled. All patients were concurrently prescribed antipsychotic medication. Assessments were made at baseline, four weeks and six months later. The primary outcome was a delusion score derived from the Positive and Negative Syndrome Scale (PANSS). The Psychotic Symptom Rating Scales (PSYRATS) as well as cognitive measures served as secondary outcomes. RESULTS: Completion at follow-up was 86%. According to intention-to-treat (ITT) analyses, patients in the MCT group showed significantly greater symptom reduction on the PANSS delusion subscore (follow-up), PANSS positive score (post-treatment) and PSYRATS delusion score (post-treatment and follow-up). Improvement on the PANSS positive scale at post-treatment and follow-up was positively correlated with the number of attended MCT sessions. No changes were seen for other psychopathological syndromes. DISCUSSION: MCT, a low-intensity training aimed at enhancing patients' awareness of cognitive biases subserving paranoia, led to improvement in delusion symptoms relative to the control condition and over and above the effects of antipsychotic medication. This improvement was sustained at follow-up.

Delusional jealousy and person directed hostility: 5-year follow-up of a patient after anoxic brain injury.

AIM: This study presents a case report on the emergence of delusional jealousy and person-directed hostility in a patient following anoxic brain injury. CASE STUDY: The patient did not have a pre-injury history of mental illness, nor a family history of a psychotic disorder. This patient was followed-up over a 5-year period and his history of treatment response, violence risk management and successful rehabilitation are presented. This study also highlights issues in relation to continuation of treatment with antipsychotic medication, use of compulsory admission under the Mental Health Act and principles of risk assessment and risk management.

An effective environmental intervention for management of the 'mirror sign' in a case of probable Lewy body dementia.

The term 'mirror sign' refers to the inability to recognize the reflection of oneself in a mirror, while the ability to recognize others' faces often remains intact. In this article, we present a case of an 85-year-old woman, with probable Lewy body dementia, who stably exhibited a delusional 'mirror sign' for a period of 9 months. Following a straightforward, ecological, non-pharmacological intervention, her 'mirror sign' delusion was no longer present.

Isolated prospective confabulation in Wernicke-Korsakoff syndrome: a case for reality filtering.

A 57-year-old man suffered severe amnesia and disorientation, accompanied by content-specific confabulation, due to an alcoholic Wernicke-Korsakoff syndrome. For months, he was deeply concerned about a single obligation that he thought he had to respond to, but which he had already assumed 20 years previously. This monothematic, prospective confabulation was associated with failures of reality filtering as previously documented in behaviorally spontaneous confabulation and disorientation: the patient failed to suppress the interference of currently irrelevant memories and to abandon anticipations that were no longer valid (impaired extinction capacity). Magnetic resonance imaging showed damage to the mamillary bodies and the dorsomedial thalamic nucleus. Positron emission tomography (FDG-PET) showed extended orbitofrontal hypometabolism. We suggest that isolated prospective confabulation shares the core feature (acts and thoughts based on currently irrelevant memory), mechanism (failure of reality filtering), and anatomical basis (orbitofrontal dysfunction) with behaviorally spontaneous confabulations.

Improving cognitive treatments for delusions.

A clear challenge for schizophrenia research is to improve markedly the efficacy of psychological treatments for delusional beliefs. Effect sizes for the first generation of cognitive approaches are weak to moderate. These therapies now lag behind the transformation over the past ten years in understanding the causes of delusions. This paper advocates an interventionist-causal model approach: to focus on one putative causal factor at a time, show that an intervention can change it, and examine the subsequent effects on the delusional beliefs. A number of new studies that illustrate this approach with patients with schizophrenia spectrum disorders who have not responded to previous treatment are reviewed. These early stage studies show great promise in terms of efficacy, although remain to be subjected to methodologically rigorous evaluation. The advantages and difficulties of the interventionist approach applied to psychosis are considered, and future studies are highlighted. The importance for clinical services of cognitive approaches to psychosis will increase further if the theoretical advances can be translated into treatment.

[Cultural aspects in depression masked by psychotic symptoms in Maghreb countries: three case reports]. / Aspects culturels dans la dépression masquée par des symptômes psychotiques.

CASE REPORTS: In this study, we will describe three observations of depression "masked" by persecution delirium and/or hallucinations, to illustrate the role that the cultural factor could play in the expression and care of depression. In the first two observations, the persecutor was a group that was apparently difficult to circumscribe: the persecution appeared more important than the persecutor. In these two cases, persecution also had a depreciating role for the patient. In the third observation, the hallucinatory manifestations cast a slur on self-esteem and caused narcissistic injury. DISCUSSION: Analysis of the cultural context allows us to understand the depressive significance of such psychotic symptoms. In the traditional societies, depression is strongly related to the cultural context, it is often expressed by the fear of being punished or denied by the group, and a feeling of treason towards the community. The punishment can be direct or indirect, carried out by imaginary beings, "the djinn", or by any disease. According to Freud, the guilt is expressed by the fear of the vengeance of a dead man's spirit, which is then going to persecute the culprit. This persecution, which has a value of punishment, is based on the mechanism of the projection. In the same sense, Freud explained that the death, as a sequel of the disease, is the vengeance of the dead man's spirit in the living. In all religions, the impulses, the thoughts disapproved by the community, are attributed to Satan who etymologically means "the enemy" or "the opponent". This latter plays an important role in relieving fears, the sense of guilt and the disapproved thoughts. There is also involvement of the projection mechanism. So, guilt could be expressed by delirious ideas such as the conviction of being the victim of a demonic possession, to be under a spell or to be persecuted. CONCLUSION: Thus, taking the cultural context into account would allow us to fundamentally understand the depressive meaning of the delirious symptomatology of persecution, which is taken from a popular theory of misfortune shared and validated by the familial and the social circle of acquaintances. Plantine postulates that the psychotic conflict takes the subject away from the standards of his own culture. In the case of our three patients, we should try to establish a form of communication, to prevent them from falling into alienation. Thus, we must think about our attitude facing a patient who is diagnosed as depressed or even psychotic, while the patient believes he/she is possessed by a "Djinn". The therapeutic attitude should be adapted to the cultural dimension of the case. Thus, in situations similar to the studied cases, the therapy should be essentially based on the development of a psychotherapeutic relationship, rather than a pharmacotherapy, one should be careful not to compromise the cultural means of restoring psychic disorders such as the traditional therapy.

Transition to independent accommodation for adults with schizophrenia.

OBJECTIVE: The aim of this exploratory study was to investigate the process of transition to independent accommodation for people with schizophrenia. METHOD: The study employed a grounded theory approach. Multiple semi-structured and responsive e-mails and interviews were conducted with a total of seven participants currently living in independent accommodation. Through constant-comparative analysis of interview and e-mail data, three central processes were identified. RESULTS: The three processes are developing a sense of control; establishing a relationship between illness and place; and attaining a sense of belonging. CONCLUSION: By attending to each of these three processes, mental health professionals may better assist people with schizophrenia to make a successful transition to independent accommodation, and in turn, to living well in the community.

How frequent is chronic multiyear delusional activity and recovery in schizophrenia: a 20-year multi-follow-up.

To determine how frequent chronic multiyear delusional activity is in modern-day schizophrenia, we studied 200 patients over a 20-year period. We also studied the relation of delusions to hallucinations and thought disorder-disorganization, to work disability, and to later periods of global recovery and assessed several protective factors against delusional activity. The sample was assessed 6 times over 20 years and includes 43 patients with schizophrenia. Participants were evaluated at each follow-up for delusions, hallucinations, thought disorder-disorganization, work disability, and global recovery. Possible protective factors were assessed prospectively at index hospitalization. Twenty-six percent of the patients with schizophrenia were delusional at all follow-ups over the 20 years. Overall, 57% had frequently recurring or persistent delusions. A subgroup of over 25% of the schizophrenia patients had no delusional activity at any of the 6 follow-ups over 20 years. Schizophrenia patients with posthospital delusional activity had increased work disability (P < .05). Delusions that persisted after the acute phase in schizophrenia patients predicted a lower likelihood of future global recovery (P < .01). In conclusion, slightly over half of modern-day schizophrenia patients are vulnerable to frequent or "chronic" delusional activity after the acute phase. Schizophreniform patients and other types of psychotic disorders are vulnerable to posthospital delusional activity, but less frequently, less severely, and more episodically. Delusional activity is associated with work disability. Internal factors such as good premorbid developmental achievements and favorable prognostic factors are protective factors that reduce the probability of chronic multiyear, delusional activity in schizophrenia (P < .01).

Recovery as discovery.

This first person account describes recovery as discovery of new meanings and opportunities in life. It travels through a journey from illness to wellness, from darkness and despair to light and hope, from futility to fruitfulness, as well as, from a state of death and loss to new life.

Passive and active schizophrenia: toward a new descriptive micropsychopathology.

The "experiences" reported by individuals affected by schizophrenia are fundamental components of the descriptive approach adopted by current diagnostic systems for mental disorders and by clinical diagnostic interviews and rating scales for the assessment of the symptoms of schizophrenia. However, the technical literature does not rely on a specific definition of experiences in schizophrenia. This article introduces a specific, restrictive, operationalized definition of the "experiential substrate" of schizophrenia, defined by the "self-giving" "passive experiences" of the disorder that break into the consciousness of the affected individual, and are distinguished from the "active" acts of judgment formulation and conviction/belief attainment. The experiential substrate of schizophrenia may be considered similar to the experiential substrate of pain. The operationalization of the definition of passive experiences can enable the experiential substrate of schizophrenia to be acknowledged as an independent domain with a specific role in the assessment of the disorder, a role that is substantially omitted or ignored by current research and practice. The term "descriptive micropsychopathology" is proposed for this new method aimed to describe passive experiences and active judgments as independent domains to enhance the reformulation of criteria for symptom assessment and, consequently, reformulation of the criteria for the assessment of the efficacy and effectiveness of interventions aimed at prevention, care, and rehabilitation in schizophrenia. A new measure focusing on the evaluation of the passive experiences of schizophrenia and on the disturbance they cause to patients is also described.
