Motor learning and performance in schizophrenia and aging: two different patterns of decline.

Psychomotor slowing has consistently been observed in schizophrenia, however research on motor learning in schizophrenia is limited. Additionally, motor learning in schizophrenia has never been compared with the waning of motor learning abilities in the elderly. Therefore, in an extensive study, 30 individuals with schizophrenia, 30 healthy age-matched controls and 30 elderly participants were compared on sensorimotor learning tasks including sequence learning and adaptation (both explicit and implicit), as well as tracking and aiming. This paper presents new findings on an explicit motor sequence learning task, an explicit verbal learning task and a simple aiming task and summarizes all previously published findings of this large investigation. Individuals with schizophrenia and elderly had slower Movement Time (MT)s compared with controls in all tasks, however both groups improved over time. Elderly participants learned slower on tracking and explicit sequence learning while individuals with schizophrenia adapted slower and to a lesser extent to movement perturbations in adaptation tasks and performed less well on cognitive tests including the verbal learning task. Results suggest that motor slowing is present in schizophrenia and the elderly, however both groups show significant but different motor skill learning. Cognitive deficits seem to interfere with motor learning and performance in schizophrenia while task complexity and decreased movement precision interferes with motor learning in the elderly, reflecting different underlying patterns of decline in these conditions. In addition, evidence for motor slowing together with impaired implicit adaptation supports the influence of cerebellum and the cerebello-thalamo-cortical-cerebellar (CTCC) circuits in schizophrenia, important for further understanding the pathophysiology of the disorder.

Impaired Sensorimotor Adaption in Schizophrenia in Comparison to Age-Matched and Elderly Controls.

BACKGROUND: The "cognitive dysmetria hypothesis" of schizophrenia proposes a disrupted communication between the cerebellum and cerebral cortex, resulting in sensorimotor and cognitive symptoms. Sensorimotor adaptation relies strongly on the function of the cerebellum. OBJECTIVES: This study investigated whether sensorimotor adaptation is reduced in schizophrenia compared with age-matched and elderly healthy controls. METHODS: Twenty-nine stably treated patients with schizophrenia, 30 age-matched, and 30 elderly controls were tested in three motor adaptation tasks in which visual movement feedback was unexpectedly altered. In the "rotation adaptation task" the perturbation consisted of a rotation (30° clockwise), in the "gain adaptation task" the extent of the movement feedback was reduced (by a factor of 0.7) and in the "vertical reversal task," up- and downward pen movements were reversed by 180°. RESULTS: Patients with schizophrenia adapted to the perturbations, but their movement times and errors were substantially larger than controls. Unexpectedly, the magnitude of adaptation was significantly smaller in schizophrenia than elderly participants. The impairment already occurred during the first adaptation trials, pointing to a decline in explicit strategy use. Additionally, post-adaptation aftereffects provided strong evidence for impaired implicit adaptation learning. Both negative and positive schizophrenia symptom severities were correlated with indices of the amount of adaptation and its aftereffects. CONCLUSIONS: Both explicit and implicit components of sensorimotor adaptation learning were reduced in patients with schizophrenia, adding to the evidence for a role of the cerebellum in the pathophysiology of schizophrenia. Elderly individuals outperformed schizophrenia patients in the adaptation learning tasks.

The Role of Kynurenines in Cognitive Dysfunction in Bipolar Disorder.

INTRODUCTION: Chronic low-grade inflammation is suggested to play a pathophysiological role in bipolar disorder (BD) and its related cognitive dysfunctions. Although kynurenine (KYN) pathway metabolites are key inflammatory mediators, studies investigating the association between KYN metabolism and cognition in BD are scarce. We aimed to explore the relationship between KYN metabolism and cognitive functioning across different mood states in BD. METHODS: Sixty-seven patients with BD (35 depressed and 32 [hypo] manic) and 29 healthy controls were included. Cognitive functioning was assessed at 3 time intervals (baseline, 4, and 8 months) assessing processing speed, sustained attention, verbal memory, working memory, and response inhibition. Plasma samples for quantification of 3-hydroxykynurenine, quinolinic acid, and kynurenic acid (KYNA) were concurrently provided. Linear mixed models were used for statistical analysis. RESULTS: The manic group showed deficits in all assessed cognitive domains with the exception of verbal memory at all test moments. The bipolar depression group showed deficits in the processing speed at all test moments. Throughout the whole follow-up period, KYNA was significantly lower in both patient groups than in controls. Only in the bipolar depression group, low KYNA was associated with worse global cognitive functioning (B = 0.114, p = 0.02) and slower processing speed in particular (B = 0.139, p = 0.03). CONCLUSION: Only in the bipolar depression group, lower KYNA was associated with worse cognitive functioning. Future large-scale longitudinal studies are warranted to confirm the role of KYN metabolites in cognitive impairment in patients with BD and the possible therapeutic implications of this relationship.

Evaluation of a new online cognitive assessment tool in breast cancer survivors with cognitive impairment: a prospective cohort study.

INTRODUCTION: Currently cancer-related cognitive impairment (CRCI) is mainly assessed by means of questionnaires, which is very laborious for the patients and the supervising physician. We evaluated a new online cognitive assessment tool, the MyCognition Quotient (MyCQ, Cambridge) in breast cancer survivors with CRCI, and compared the results with a psychometric test measuring cognitive complaints, depression, and anxiety. MATERIALS AND METHODS: In this prospective study, 46 adult patients between 18 and 70 years old with a diagnosis of BC were studied, all complaining of disturbing cognitive impairment. They participated in a physical cognitive rehabilitation program. The patients had an online cognitive assessment (MyCQ Med by MyCognition) every 4 weeks on their home computer. In addition patients were assessed in the outpatient clinic by the principal investigator at baseline, after 3 and 6 months using the following validated neuro-psychological surveys: the Hospital Anxiety and Depression Scale (HADS), Beck Cognitive Insight Scale (BCIS), and Cognitive Failure Questionnaire (CFQ). MyCQ scores were correlated with the results of these surveys. RESULTS: Only weak correlations could be found between overall MyCQ or the MyCQ subtests with the psychometric tests (between - 0.43 and 0.458) at baseline and when combining data at time point 0, 3, and 6 months. Linear mixed models showed there was a significant association between Latency Choice Reaction Time and CFQ (continuous; p = 0.026). An AUC of 0.640 and a cut-off of 481.5 ms in Latency Choice Reaction Time were found to distinguish patients with CFQ below 44 to patients with CFQ above 44 (sensitivity 0.63 and specificity 0.73). In Latency Coding an AUC of 0.788 and a cut-off of 1316 ms were found to distinguish non-depressive patients from patients likely to present with depressive symptoms (sensitivity 0.75 and specificity 0.76). CONCLUSION: MyCQ cannot replace the various psychometric tests. However, abnormal Latency in cognitive tests, Choice Reaction Time and Coding, seems promising to be used as a screening tool to detect specific aspects of abnormal cognitive functioning in patients with cognitive complaints and depressive symptoms.

Inflammatory Markers May Inform the Effects of Electroconvulsive Therapy on Cognition in Patients with Depression.

INTRODUCTION: The neurobiological mechanisms underlying the acute cognitive effects of electroconvulsive therapy (ECT) remain poorly understood. Prior research has shown that proinflammatory cytokines such as IL-6, TNF-α, IL1-ß, and IL-10 may interfere with cognitive functioning. Interestingly, immunomodulation is one of the proposed modes of action of ECT. This study investigates whether changes of peripheral levels of IL-6, TNF-α, IL1-ß, and IL-10 are related to changes in cognitive functioning following ECT. METHODS: In the week before and 1 week after an acute course of ECT, 62 patients suffering from depression underwent a neuropsychological evaluation to assess their processing speed using the Symbol Digit Substitution Test (SDST), verbal episodic memory using the Hopkins Verbal Learning Test-Revised (HVLT-R), and their retrospective autobiographic memory using the Autobiographical Memory Interview (AMI) with the peripheral inflammatory markers being measured at the same 2 time points. RESULTS: Patients improved drastically following ECT, while their main performance on both the HVLT-R and AMI declined and their SDST scores remained stable. The levels of IL-6 and IL1-ß had both decreased, where the decrease in IL-6 was related to the decrease in HVLT-R scores. Higher baseline IL-10 levels were associated with a more limited decrease of the HVLT-R scores. CONCLUSION: Our findings tentatively suggest that the effects of ECT on verbal episodic memory may be related to the treatment's immunomodulatory properties, most notably due to decreased IL-6 levels. Moreover, baseline IL-10 appears to be a potential biomarker to predict the effects of ECT on verbal episodic memory. Whilst compelling, the results of this study should be interpreted with caution as, due to its exploratory nature, no correction for multiple comparisons was made. Further, a replication in larger cohorts is warranted.

A mood state-specific interaction between kynurenine metabolism and inflammation is present in bipolar disorder.

OBJECTIVES: Cytokines are thought to contribute to the pathogenesis of psychiatric symptoms by kynurenine pathway activation. Kynurenine metabolites affect neurotransmission and can cause neurotoxicity. We measured inflammatory markers in patients with bipolar disorder (BD) and studied their relation to kynurenine metabolites and mood. METHODS: Patients with BD suffering from an acute mood episode were assigned to the depressive (n = 35) or (hypo)manic (n = 32) subgroup. Plasma levels of inflammatory markers [cytokines, C-reactive protein] and kynurenine metabolites [tryptophan (TRP), kynurenine (KYN), 3-hydroxykynurenine (3-HK), quinolinic acid (QA), kynurenic acid (KYNA)] were measured on 6 time points during 8 months follow-up. Biological marker levels in patients were compared to controls (n = 35) and correlated to scores on mood scales. Spearman correlations and linear mixed models were used for statistical analysis. RESULTS: Twenty patients of the manic subgroup, 29 of the depressive subgroup, and 30 controls completed the study. The manic subgroup had a rapid remission of mood symptoms, but in the depressive subgroup subsyndromal symptoms persisted. No differences in inflammation were found between groups. A strong correlation between tumor necrosis factor-α and KYN, KYN/TRP, 3-HK and QA (ρ > 0.60) was specific for the manic group, but only at baseline (during mania). The depressive subgroup had a lower neuroprotective ratio (KYNA/3-HK, P = .0004) and a strong association between interferon-y and kynurenine pathway activation (P < .0001). KYNA was low in both patient groups versus controls throughout the whole follow-up (P = .0008). CONCLUSIONS: Mania and chronic depressive symptoms in BD are accompanied by a strong interaction between inflammation and a potentially neurotoxic kynurenine metabolism.

Symptom Profile and Clinical Course of Inpatients with Unipolar versus Bipolar Depression.

BACKGROUND: Although differences in symptom profiles and outcome between depressive patients with an underlying major depressive disorder (MDD) and bipolar depression (BD) have been reported, studies with sequential short-interval assessments in a real-life inpatient setting are scarce. OBJECTIVES: To examine potential differences in symptom profile and course of depressive symptomatology in depressive inpatients with underlying MDD and BD. METHODS: A cohort of 276 consecutive inpatients with MDD (n = 224) or BD (n = 52) was followed during their hospitalization using routine outcome monitoring (ROM), which included a structured diagnostic interview at baseline (Mini-International Neuropsychiatric Interview Plus [MINI-Plus]) and repeated 17-item Hamilton Depression Rating Scale every 2 weeks. MDD and BD were compared regarding their symptom profiles and time to response and remission. Furthermore, the concordance between the MINI-Plus and clinical diagnosis was analyzed. RESULTS: Patients were on average 52 and 47 years old in the MDD and BD group, respectively, and 66 versus 64% were female. Compared to patients with BD, patients with MDD scored higher on weight loss (p = 0.02), whereas the BD group showed a higher long-term likelihood of response (hazard ratio = 1.93, 95% confidence interval 1.16-3.20, p for interaction with time = 0.04). Although the same association was seen for remission, the interaction with time was not significant (p = 0.48). Efficiency between the MINI-Plus and clinical diagnosis of BD was high (0.90), suggesting that the MINI-Plus is an adequate ROM diagnostic tool. CONCLUSIONS: In routine clinical inpatient care, minor differences in the symptom profile and the course of depressive symptomatology may be helpful in distinguishing MDD and BD, particularly when using sequential ROM assessments.

Inflammation, Hippocampal Volume, and Therapeutic Outcome following Electroconvulsive Therapy in Depressive Patients: A Pilot Study.

INTRODUCTION: Electroconvulsive therapy (ECT) influences the concentration of peripheral inflammatory markers, such as interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α). In which way this immune effect contributes to the impact of ECT on the central nervous system in depression remains unknown. OBJECTIVE: The aim of this study was to examine whether the hippocampal volumetric increase in depressed patients treated with ECT is related to changes in peripheral IL-6 and TNF-α levels. METHODS: IL-6 and TNF-α plasma levels were measured in 62 patients 1 week before and after an acute course of ECT. Hippocampal volumes were analyzed in a magnetic resonance imaging (MRI) subsample of 13 patients at the same time points. RESULTS: A significant decrease in IL-6 levels was observed in the total sample and a significant increase in hippocampal volume in the MRI subsample. The reduction of peripheral IL-6 correlated with an increase in total hippocampal volume. A more limited decrease of TNF-α correlated with a more limited increase of both the total and left hippocampus volumes. CONCLUSION: This pilot study is the first to highlight the link between peripheral immune changes and hippocampal volume increase following ECT. Further research is required to conclude whether ECT indeed exerts its central effect on the brain via changes of peripheral inflammatory markers.

Anhedonia in Depressive Disorder: A Narrative Review.

Since the introduction of DSM-III anhedonia has become a core depressive criterion and is defined as the loss of interest or pleasure. Although the origin of the word goes back to the end of the 19th century and numerous anhedonic symptoms are described in classic texts on depression, this centrality in the diagnosis of depression is only recent. Anhedonia is best described as a symptom complex with unclear boundaries cutting across the tripartite model of the mind (affect, volition, and cognition). Popular concepts of anhedonia pertain to the pleasure cycle and positive affectivity. These concepts partially overlap and are often mixed up, but clearly stem from different theoretical backgrounds: the affective science of reward processing versus more general, dimensional modelling of affect. The former concept seems more suitable to understand anhedonic emotions, the latter more suitable to understand anhedonic mood or trait. This narrative review covers the history of "anhedonia," the different anhedonic phenomena, and psychopathological concepts. An attempt is made to go beyond a merely descriptive psychopathology. Neurobiological and psychological insights shed a light on how symptoms are made and interconnected; these insights possibly call for a new psychopathological language.

Impairment of Both Reward and Punishment Learning in Males Who Have Sexually Offended Against a Child.

Prior studies suggest that persons with a sexual offense against a child (PSOCs) present with an impairment in learning from reinforcement, which may contribute to the behavioral dysregulation often seen in PSOCs. Therefore, gaining more insight into the nature of this impairment seems essential to better understand child sexual (re)offending. Using a passive avoidance task, we found that PSOCs (n = 57) have difficulties with selecting behaviors that are associated with reward and suppressing behaviors that are associated with punishment relative to nonoffending men (n = 33), but not compared with persons with a nonsexual offense history (n = 31). The latter ability was particularly compromised in nonpedophilic PSOCs. By unraveling a source of pathology in the mechanisms that are involved in behavioral control, this study helps setting a step toward new, more tailored, therapeutic approaches.

State-associated changes in longitudinal [18F]-PBR111 TSPO PET imaging of psychosis patients: Evidence for the accelerated ageing hypothesis?

OBJECTIVE: To determine whether state-associated changes in microglial activity, measured with translocator-protein positron emission tomography (TSPO PET), can be identified in psychosis patients through longitudinal evaluation of their regional tracer uptake over the clinical course from acute psychosis to post-treatment follow-up, and comparison to healthy controls. We also evaluated the relation between tracer uptake, clinical symptoms and peripheral immunological markers. METHOD: Second-generation radioligand [18F]-PBR111 TSPO PET-CT was used for longitudinal dynamic imaging in 14 male psychosis patients and 17 male age-matched healthy control subjects. Patients were first scanned during an acute psychotic episode followed by a second scan after treatment. Prior genotyping of subjects for the rs6917 polymorphism distinguished high- and mixed-affinity binders. The main outcome was regional volume of distribution (VT), representing TSPO binding. Plasma concentrations of CRP, cytokines and kynurenines were measured at each timepoint. RESULTS: We found a significant three-way interaction between time of scan, age and cohort (cortical grey matter F6.50, p.020). Age-dependent differences in VT existed between cohorts during the psychotic state, but not at follow-up. Patients' relative change in VT over time correlated with age (cortical grey matter Pearson's r.574). PANSS positive subscale scores correlated with regional VT during psychosis (cortical grey matter r.767). Plasma CRP and quinolinic acid were independently associated with lower VT. CONCLUSIONS: We identified a differential age-dependent pattern of TSPO binding from psychosis to follow-up in our cohort of male psychosis patients. We recommend future TSPO PET studies in psychosis patients to differentiate between clinical states and consider potential age-related effects.

Cognitive Deficits in Older Adults With Psychotic Depression: A Meta-Analysis.

A major depressive disorder with psychotic features, that is, psychotic depression (PD), is often accompanied by cognitive deficits, particularly in older patients. We aimed to assess to what extent various cognitive domains are affected in older patients with PD compared to those with nonpsychotic depression (NPD). Therefore, a systematic search was conducted in Medline, Embase, Web of Science, the Cumulative Index to Nursing and Allied Literature (CINAHL), Google Scholar, and Cochrane for all relevant studies. Hereafter, we conducted a meta-analysis of seven studies on cognitive deficits in older adults (55+ years), comparing patients with PD and patients with NPD. Compared to patients with NPD, those with PD not only showed a significantly poorer performance on overall cognitive function, with a Hedges' g effect size of -0.34 (95% confidence interval: -0.56; -0.12; p = 0.003), but also on nearly all separate cognitive domains, with Hedges' g effect sizes ranging from -0.26 to -0.64 (all p's <0.003), of which attention was most adversely affected. Verbal fluency showed no significant effect, although this analysis may have been underpowered. The funnel plot suggested no significant publication bias (Egger test intercept: -2.47; 95% confidence interval: -5.50; 0.55; p = 0.09). We conclude that older patients with PD show more cognitive deficits on all cognitive domains, except for verbal fluency, compared to patients with NPD. It is crucial that clinicians and researchers take cognitive deficits into consideration in older adults with PD.

Performance of the Psychotic Depression Assessment Scale as a Predictor of ECT Outcome.

OBJECTIVES: The presence of psychotic symptoms is an important predictor of responsiveness to electroconvulsive therapy (ECT). This study investigates whether a continuous severity measure, the Psychotic Depression Assessment Scale (PDAS), is a more accurate predictor. METHODS: Depression severity was assessed before and after the ECT course using the Montgomery-Asberg Depression Rating Scale (MADRS) in 31 patients with psychotic depression and 34 depressed patients without psychotic symptoms. Logistic regression models for MADRS response and remission were fitted, with either the PDAS total score or the dichotomous predictors "absence/presence of psychotic symptoms" as the independent variables. Age, episode duration, and treatment resistance were added as covariates. RESULTS: Both the asserted presence of psychotic symptoms and a higher PDAS total score reflected MADRS response (areas under the curve, 0.83 and 0.85, respectively), with MADRS remission also being predicted by the presence of psychotic symptoms and higher PDAS scores (areas under the curves, 0.86 and 0.84, respectively). Age was a contributor to these prediction models, with response and remission rates being highest in the older patients. Psychotic Depression Assessment Scale scores decreased significantly during ECT: at end point, 81.5% of the patients showed significant response and 63.9% had achieved remission. CONCLUSIONS: The PDAS indeed accurately predicts response to and remission after ECT in (psychotic) depression and most pronouncedly so in older patients but seems to have no clear advantage over simply verifying the presence of psychotic symptoms. This could be the consequence of a ceiling effect, as ECT was extremely effective in patients with psychotic depression.ClinicalTrials.gov: Identifier: NCT02562846.

Reinforcement learning in child molesters.

BACKGROUND: Child molesters form a heterogeneous group, but one generally shared characteristic is maladaptive, rigid behaviour. Impairments in reinforcement learning may explain these maladaptive tendencies, but this has not been systematically investigated. Further, it is not known if such impairments vary with subtype of child molesters. AIMS: To investigate the presence of impairments in reinforcement learning among child molesters and to test for differences in patterns of impairment with subtype. METHODS: A group of 59 child molesters was recruited from several prisons in a two-stage screening process, the first using records and the second interview; a comparison group of 33 offenders who had never committed a sex offence and who denied paedophile ideation was similarly recruited; 36 nonoffender comparison men were recruited by social media and word of mouth. Each was asked to perform a probabilistic reversal learning task, in which stimulus-outcome contingencies had to be learned. RESULTS: Child molesters, as a group, made significantly more errors on the probabilistic reversal learning task than the nonoffenders; the comparison offenders and the nonoffenders gained similar scores, although findings may have been confounded by older age in the child molester group. Nonpaedophilic child molesters had significantly worse scores than paedophilic child molesters. CONCLUSIONS: Child molesters, especially those not diagnosed with paedophilia, have deficits during both the acquisition and reversal of contingencies, suggesting reinforcement learning deficits that may undermine their capacity to benefit maximally from therapy without preliminary work to repair those deficits, possibly in conjunction with extending the offender programmes. Testing before programme entry would enable accurate targeting of scarce resources in this respect.

[Psychotic depression in older adults: an overview]. / Psychotische depressie bij ouderen: een overzicht.

Psychotic depression is a frequent, severe psychiatric condition in older depressive inpatients aged 60 years and older. Older adults with a psychotic depression exhibit specific symptoms that are different from those in younger adults with psychotic depression. Moreover, the symptoms are also different from those in older adults  with a major depression without psychotic features. The recommended treatment consists of a tricyclic antidepressant, with or without addition of an antipsychotic, or electroconvulsive therapy. These treatments may however produce significant side effects that require intensive monitoring. In this article we present an overview of clinical topics regarding the diagnosis and treatment of older people with a psychotic depression.

Prediction of electroconvulsive therapy response and remission in major depression: meta-analysis.

BACKGROUND: Electroconvulsive therapy (ECT) is considered to be the most effective treatment in severe major depression. The identification of reliable predictors of ECT response could contribute to a more targeted patient selection and consequently increased ECT response rates. Aims To investigate the predictive value of age, depression severity, psychotic and melancholic features for ECT response and remission in major depression. METHOD: A meta-analysis was conducted according to the PRISMA statement. A literature search identified recent studies that reported on at least one of the potential predictors. RESULTS: Of the 2193 articles screened, 34 have been included for meta-analysis. Presence of psychotic features is a predictor of ECT remission (odds ratio (OR) = 1.47, P = 0.001) and response (OR = 1.69, P < 0.001), as is older age (standardised mean difference (SMD) = 0.26 for remission and 0.35 for response (P < 0.001)). The severity of depression predicts response (SMD = 0.19, P = 0.001), but not remission. Data on melancholic symptoms were inconclusive. CONCLUSIONS: ECT is particularly effective in patients with depression with psychotic features and in elderly people with depression. More research on both biological and clinical predictors is needed to further evaluate the position of ECT in treatment protocols for major depression. Declaration of interest None.

The Maudsley Staging Method as predictor of electroconvulsive therapy effectiveness in depression.

OBJECTIVE: To investigate the potential role of the Maudsley Staging Method (MSM) in the prediction of electroconvulsive therapy (ECT) outcome in severely depressed adults. METHOD: Between August 2015 and August 2017, 73 consecutive patients with a major depressive episode (DSM-IV-TR) scheduled for ECT were recruited. Prior to their first ECT session, the MSM was completed to assess the level of therapy resistance. To determine the reduction in depression severity and response and remission rates, symptom severity was assessed at baseline and within one week after the last ECT session using the 17-item Hamilton Depression Rating Scale (HDRS17). RESULTS: The percentage of symptom reduction following ECT was best predicted by the MSM episode duration and depression severity factors (R2 completer sample 0.24). Episode duration alone was the best predictor of remission (area under the ROC curve for completers: 0.72). Adding age to the models increased their predictive capacity. CONCLUSION: An adapted version of the MSM gauging shorter episode duration, more severe depressive symptoms and older age is significantly associated with ECT effectiveness in adults with severe recurrent depression and is thus highly suitable for use in clinical practice, promoting the shared treatment decision-making process.

The Effect of Electroconvulsive Therapy on Hypoperfusion in Psychotic Bipolar Depression: A Case Study.

The pharmacological treatment of bipolar depression has low response rates. Twenty percent to 30% of patients have an insufficient response to medication. The guidelines suggest that electroconvulsive therapy (ECT) is the next step. The aim of this case study is to evaluate the effect of ECT on the perfusion of the brain in bipolar depression, while monitoring effects on mood and cognition. We present a case study of 56-year-old female patient who suffered from a psychotic depression and cognitive impairment. Before ECT, she took several antidepressants and atypical antipsychotics, but there was no improvement in her symptoms. By using single-photon emission computed tomography, we obtained the status of the regional cerebral blood flow and found a decreased perfusion in the anterior part of the left temporal lobe, the posterior part of the right temporal lobe, and in the left gyrus frontalis inferior. This is consistent with previous findings. Electroconvulsive therapy resulted in a resolution of the patient's depression and an improvement in her neurocognitive performance. Markedly, this was only in visual learning and working memory, domains in which the patient was already relatively stronger pre-ECT treatment. A new single-photon emission computed tomography, 4 weeks after the last ECT course, showed normalization of the regional cerebral blood flow.

Forensic Assertive Community Treatment in a Continuum of Care for Male Internees in Belgium: Results After 33 Months.

Non-forensic or regular assertive community treatment (ACT) has positive effects on non-forensic outcomes but has poor effects on forensic outcome measures. In this study, we examined non-forensic and forensic outcome measures of a forensic adaptation of ACT (ForACT) within a continuum of care for internees. Data were collected retrospectively from files of 70 participants in the ForACT group who had been released from a forensic hospital. The control group comprised internees who had left prison and entered community-based care (n = 56). The ForACT group demonstrated significantly better outcomes on forensic measures, such as arrests and incarcerations, and had better community tenure. However, this group showed high hospitalization rates. The findings indicate that this type of community-based care can be beneficial for such internees; however, internees continue to experience difficulties reintegrating into society.
