RESUMEN

BACKGROUND: Cerebral malaria is one of the most severe complications attributed to protozoal infection by Plasmodium falciparum, gaining prominence in children mortality rates in endemic areas. This condition has a complex pathogenesis associated with behavioral, cognitive and motor sequels in humans and current antimalarial therapies have shown little effect in those aspects. Natural products with antioxidant and anti-inflammatory properties have become a valuable alternative therapeutic option in the treatment of distinct conditions. In this context, this study investigated the neuroprotective effect of Euterpe oleracea (açai) enriched diet during the development of experimental cerebral malaria induced by the inoculation of Swiss albino mice with Plasmodium berghei ANKA strain. METHODS: After Plasmodium infection, animals were maintained on a feeding with Euterpe oleracea enriched ration and parameters such as survival curve, parasitemia and body weight were routinely monitored. The present study has also evaluated the effect of açai-enriched diet on the blood-brain barrier leakage, histological alterations and neurocognitive impairments in mice developing cerebral malaria. RESULTS: Our results demonstrate that between 7th-19th day post infection the survival rate of the group treated with açai enriched ration was higher when compared with Plasmodium-infected mice in which 100% of mice died until the 11th days post-infection, demonstrating that açai diet has a protective effect on the survival of infected treated animals. The same was observed in the brain vascular extravasation, where Evans blue dye assays showed significantly less dye extravasation in the brains of Plasmodium-infected mice treated with açai enriched ration, demonstrating more preserved blood-brain barrier integrity. Açai-enriched diet also attenuate the histopathological alterations elicited by Plasmodium berghei infection. We also showed a decrease of the neurological impairments arising from the exposure of cerebral parenchyma in the group treated with açai diet, ameliorating motor and neuropsychiatric changes, analyzed through the SHIRPA protocol. CONCLUSION: With these results, we conclude that the treatment with açai enriched ration decreased the mortality of infected animals, as well as protected the blood-brain barrier and the neurocognitive deficits in Plasmodium-infected animals.

RESUMEN

Dravet Syndrome (DS) is caused by mutations in the Scn1a gene encoding the α1 subunit of the sodium channel Nav1.1, which results in febrile seizures that progress to severe tonic-clonic seizures and associated comorbidities. Treatment with cannabidiol has been approved for the management of seizures in DS patients, but it appears to be also active against associated comorbidities. In this new study, we have investigated ß-caryophyllene (BCP), a cannabinoid with terpene structure that appears to also have a broad-spectrum profile, as a useful therapy against both seizuring activity and progression of associated comorbidities. This has been studied in heterozygous conditional knock-in mice carrying a missense mutation (A1783V) in Scn1a gene expressed exclusively in neurons of the Central Nervous System (Syn-Cre/Scn1aWT/A1783V), using two experimental approaches. In the first approach, an acute treatment with BCP was effective against seizuring activity induced by pentylenetetrazole (PTZ) in wildtype (Scn1aWT/WT) and also in Syn-Cre/Scn1aWT/A1783V mice, with these last animals having a greater susceptibility to PTZ. Such benefits were paralleled by a BCP-induced reduction in PTZ-induced reactive astrogliosis (labelled with GFAP) and microgliosis (labelled with Iba-1) in the prefrontal cortex and the hippocampal dentate gyrus, which were visible in both wildtype (Scn1aWT/WT) and Syn-Cre/Scn1aWT/A1783V mice. In the second approach, both genotypes were treated repeatedly with BCP to investigate its effects on several DS comorbidities. Thus, BCP corrected important behavioural abnormalities of Syn-Cre/Scn1aWT/A1783V mice (e.g. delayed appearance of hindlimb grasp reflex, induction of clasping response, motor hyperactivity, altered social interaction and memory impairment), attenuated weight loss, and slightly delayed premature mortality. Again, these benefits were paralleled by a BCP-induced reduction in reactive astrogliosis and microgliosis in the prefrontal cortex and the hippocampal dentate gyrus typical of Syn-Cre/Scn1aWT/A1783V mice. In conclusion, BCP was active in Syn-Cre/Scn1aWT/A1783V mice against seizuring activity (acute treatment) and against several comorbidities (repeated treatment), in both cases in association with its capability to reduce glial reactivity in areas related to these behavioural abnormalities. This situates BCP in a promising position for further preclinical evaluation towards a close translation to DS patients.

RESUMEN

A cross-sectional study was conducted to evaluate patterns of gray matter changes in cognitively normal elderly adults with mild behavioral impairment (MBI). Sixteen MBI patients and 18 healthy controls were selected. All the participants underwent a neuropsychological assessment battery, including the Mini-mental State Examination (MMSE), Geriatric Depression Scale (GDS), Self-rating Anxiety Scale (SAS), and Chinese version of the mild behavioral impairment-checklist scale (MBI-C), and magnetic resonance imaging (MRI) scans. Imaging data was analyzed based on voxel-based morphometry (VBM). There was no significant difference in age, gender, MMSE score, total intracranial volume, white matter hyperdensity, gray matter volume, white matter volume between the two groups (p > 0.05). MBI group had shorter education years and higher MBI-C score, GDS and SAS scores than the normal control group (p < 0.05). For neuroimaging analysis, compared to the normal control group, the MBI group showed decreased volume in the left brainstem, right temporal transverse gyrus, left superior temporal gyrus, left inferior temporal gyrus, left middle temporal gyrus, right occipital pole, right thalamus, left precentral gyrus and left middle frontal gyrus(uncorrected p < 0.001). The grey matter regions correlated with the MBI-C score included the left postcentral gyrus, right exterior cerebellum, and left superior frontal gyrus. This suggests a link between MBI and decreased grey matter volume in cognitively normal elderly adults. Atrophy in the left frontal cortex and right thalamus in MBI patients is in line with frontal-subcortical circuit deficits, which have been linked to neuropsychiatric symptoms (NPS) in dementia. These initial results imply that MBI might be an early harbinger for subsequent cognitive decline and dementia.

RESUMEN

OBJECTIVES: To test for cerebellar involvement in motor and nonmotor impairments in Parkinson disease (PD) and to determine patterns of metabolic correlations with supratentorial brain structures, we correlated clinical motor, cognitive, and psychiatric scales with cerebellar metabolism. METHODS: We included 90 patients with PD. Motor, cognitive, and psychiatric domains were assessed, and resting-state 18FDG-PET metabolic imaging was performed. The motor, cognitive, and psychiatric scores were entered separately into a principal component analysis. We looked for correlations between these 3 principal components and cerebellar metabolism. Furthermore, we extracted the mean glucose metabolism value for each significant cerebellar cluster and looked for patterns of cerebrum-cerebellum metabolic correlations. RESULTS: Severity of impairment was correlated with increased metabolism in the anterior lobes and vermis (motor domain); the right crus I, crus II, and declive (cognitive domain); and the right crus I and crus II (psychiatric domain). No results survived multiple testing corrections regarding the psychiatric domain. Moreover, we found distributed and overlapping, but not identical, patterns of metabolic correlations for motor and cognitive domains. Specific supratentorial structures (cortical structures, basal ganglia, and thalamus) were strongly correlated with each of the cerebellar clusters. CONCLUSIONS: These results confirm the role of the cerebellum in nonmotor domains of PD, with differential but overlapping patterns of metabolic correlations suggesting the involvement of cerebello-thalamo-striatal-cortical loops.

RESUMEN

This article outlines the mental health burden of COVID-19 in the United Kingdom population, and presents preliminary evidence of less common psychiatric issues, such as paranoia and hallucinations, to which vulnerable groups in the U.K. population may be more vulnerable. It is argued that cognitive-behavioral therapy, with components of mindfulness, should be part of the therapeutic response. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

RESUMEN

We examined whether symptoms of dementia are improved by olfactory nerve stimulation in Alzheimer type dementia patients. First, a stick-type olfactory identification ability test was performed in patients with Alzheimer type dementia, to select patients without olfactory dysfunctions. Then, these patients were randomly assigned into the intervention (n = 19) and the control groups (n = 17). To evaluate the effects of olfactory nerve stimulation, we exposed the intervention group to a disinfecting ethanol with added aroma extracts from ceder and the control group to the ethanol without the added aroma extracts. Each group underwent the intervention for 8 weeks, cognitive and behavioral functions were evaluated before and after treatments using the Neuropsychiatric Inventory (NPI), the Japanese version of Zarit Caregiver Burden interview (J-ZBI), and the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog). A significant improvement was observed in the NPI score and J-ZBI in the intervention group compared to the control group at 4 and 8 weeks. On the other hand, there was no significant difference in the score of ADAS-cog. Exposure to cedar fragrance improved behavioral and psychological symptoms of dementia (BPSD) in Alzheimer type dementia and may reduce the burden of nursing care. In addition to its effectiveness, the procedure is simple and minimally invasive and would be a valuable non-pharmaceutical treatment.

RESUMEN

Purpose: Parkinson's disease (PD) is the second most common age-related neurodegenerative disorder, presenting not only with motor symptoms (resting tremor, bradykinesia, and muscular rigidity), but also with cognitive and behavioral problems that need to be addressed in a rehabilitation setting. Aim of the study was to evaluate the effects of a combined rehabilitative approach, using gait training coupled to music-based therapy, on cognitive and behavioral function in a sample of patients with PD.Materials and Methods: Forty patients, meeting the inclusion criteria, were enrolled in this study and were randomly divided into two groups. The control group (CG) underwent traditional over ground gait training, whilst the experimental group (EG) underwent gait training with the Biodex Gait Trainer 3 (a treadmill integrated with music therapy). Each subject was evaluated at baseline (T0) and after the training (T1), using specific neuropsychological and motor function tests.Results: The EG presented higher outcomes scores concerning mood and quality of life in all subscales of Psychological General Well-Being Index (i.e. anxiety, depression, health, vitality and positivity) and subscales of Brief-COPE, with regard to behavioral disengagement, positive reframing, planning, acceptance and use of emotional support, as compared to the CG. Moreover, a significant improvement in motor functioning, with regard to static and dynamic balance, was found in the EG.Conclusion: Music-based gait training rehabilitation may be considered an effective strategy to improve behavioral performances, coping strategies and rehabilitation outcomes in patients with PD.

RESUMEN

It has long been established that fighting sports such as boxing and mixed martial arts can lead to head injury. Prior work from this group on the Professional Fighters Brain Health Study found that exposure to repetitive head impacts is associated with lower brain volumes and decreased processing speed in fighters. Current and previously licensed professional fighters were recruited, divided into active and retired cohorts, and matched with a control group that had no prior experience in sports with likely head trauma. This study examined the relationship between age of first exposure (AFE) to fighting sports and brain structure (MRI regional volume), cognitive performance (CNS Vital Signs, iComet C3), and clinical neuropsychiatric symptoms (PHQ-9, Barratt Impulsiveness Scale). Brain MRI data showed significant correlations between earlier AFE and smaller bilateral hippocampal and posterior corpus callosum volumes for both retired and active fighters. Earlier AFE in active fighters was correlated with decreased processing speed and decreased psychomotor speed. Retired fighters showed a correlation between earlier AFE and higher measures of depression and impulsivity. Overall, the results help to inform clinicians, governing bodies, parents, and athletes of the risks associated with beginning to compete in fighting sports at a young age.

RESUMEN

BACKGROUND: Encephalitis due to anti-N-methyl-D-aspartate receptor antibodies (ANMDARE) is the most frequent immune-mediated encephalitis. It is distinguished by the subacute onset of neuropsychiatric symptoms. OBJECTIVE: To evaluate the characteristic neuropsychiatric symptoms and their outcome in patients diagnosed with ANMDARE. METHODS: This was a prospective, longitudinal study in patients with a diagnostic suspicion of ANMDARE that presented to the National Institute of Neurology from March 2018 to February 2019. A comparative analysis of two groups (positive N-methyl-D-aspartate receptor [NMDAR] vs. negative NMDAR antibodies in cerebrospinal fluid [CSF]) was done on admission and at discharge. Neuropsychiatric systematic assessments included the Neuropsychiatric Inventory Questionnaire, the Bush Francis Catatonia Rating Scale, the Confusion Assessment Method Severity, the Montreal Cognitive Assessment, and the Overt Agitation Severity Scale. RESULTS: 24 individuals were analysed: 14 had positive NMDAR antibodies, and 10 had negative NMDAR antibodies in CSF. On admission, agitation/aggression, euphoria/exaltation, and disinhibition were more common in patients with positive antibodies. Excited catatonia and delirium were diagnosed more frequently in patients with positive antibodies. At discharge, there was an important decrease in neuropsychiatric symptoms, but substantial cognitive impairment remained. The mean hospitalisation length was 41.71 (SD 39.33) days for patients with definitive ANMDARE (p 0.259). CONCLUSIONS: Neuropsychiatric symptoms profile in ANMDARE was associated with the early onset of euphoria/exaltation and disinhibition, accompanied by marked psychomotor agitation. When ANMDARE was suspected, the presence of excited-type catatonia and delirium showed a tendency to predict definitive ANMDARE. At discharged, most patients recovered from catatonia, delirium, and psychosis, but marked cognitive symptoms, anxiety, and depression persisted at discharge.

RESUMEN

Huntington's disease (HD) is a fatal genetic neurodegenerative disorder. It has mainly been considered a movement disorder with cognitive symptoms and these features have been associated with pathology of the striatum and cerebral cortex. Importantly, individuals with the mutant huntingtin gene suffer from a spectrum of non-motor features often decades before the motor disorder manifests. These symptoms and signs include a range of psychiatric symptoms, sleep problems and metabolic changes with weight loss particularly in later stages. A higher body mass index at diagnosis is associated with slower disease progression. The common psychiatric symptom of apathy progresses with the disease. The fact that non-motor features are present early in the disease and that they show an association to disease progression suggest that unravelling the underlying neurobiological mechanisms may uncover novel targets for early disease intervention and better symptomatic treatment. The hypothalamus and the limbic system are important brain regions that regulate emotion, social cognition, sleep and metabolism. A number of studies using neuroimaging, postmortem human tissue and genetic manipulation in animal models of the disease has collectively shown that the hypothalamus and the limbic system are affected in HD. These findings include the loss of neuropeptide-expressing neurons such as orexin (hypocretin), oxytocin, vasopressin, somatostatin and VIP, and increased levels of SIRT1 in distinct nuclei of the hypothalamus. This review provides a summary of the results obtained so far and highlights the potential importance of these changes for the understanding of non-motor features in HD.

RESUMEN

Family caregivers often feel ill-equipped to handle bothersome behavioral and psychological symptoms of dementia, such as agitation, apathy, and sleep disturbances, leading to increased caregiver distress and nursing home placement for people with dementia. Therapies for such symptoms are currently limited and non-pharmacological options are preferred, given potential side effects of medications. Neurologic music therapy (NMT) could provide an additional treatment option for managing behavioral and psychological symptoms for community-dwelling people with dementia and their caregivers. This pilot study sought to evaluate the feasibility, acceptability, and effectiveness of home-based NMT for behavioral and psychological symptoms of dementia. Eighteen persons with dementia-caregiver dyads were enrolled to receive one-hour weekly sessions of home-based NMT for 6 weeks. Demographic, quality of life, neuropsychiatric symptom, and caregiver burden and self-efficacy information was collected at baseline, 6 weeks, and 12 weeks. Seven dyads (38.9%) withdrew from therapy before completing all sessions; these participants had higher Neuropsychiatric Inventory scores and were of older age at baseline. For those who completed therapy, neuropsychiatric symptom scores improved at 6 weeks, an effect that was sustained at 12 weeks. No other outcome measures changed significantly after therapy. Initiating NMT too late in the course of dementia, when behavioral symptoms are already present, may be impractical for people with dementia and increase caregiver stress, even when provided within the home. Introducing and incorporating the principles of NMT earlier in the course of dementia could allow for increased comfort and benefit for people with dementia and their caregivers.

RESUMEN

ABSTRACTObjectives:Behavioral and psychological symptoms of dementia (BPSD) are nearly universal in dementia, a condition occurring in more than 40 million people worldwide. BPSD present a considerable treatment challenge for prescribers and healthcare professionals. Our purpose was to prioritize existing and emerging treatments for BPSD in Alzheimer's disease (AD) overall, as well as specifically for agitation and psychosis. DESIGN: International Delphi consensus process. Two rounds of feedback were conducted, followed by an in-person meeting to ratify the outcome of the electronic process. SETTINGS: 2015 International Psychogeriatric Association meeting. PARTICIPANTS: Expert panel comprised of 11 international members with clinical and research expertise in BPSD management. RESULTS: Consensus outcomes showed a clear preference for an escalating approach to the management of BPSD in AD commencing with the identification of underlying causes. For BPSD overall and for agitation, caregiver training, environmental adaptations, person-centered care, and tailored activities were identified as first-line approaches prior to any pharmacologic approaches. If pharmacologic strategies were needed, citalopram and analgesia were prioritized ahead of antipsychotics. In contrast, for psychosis, pharmacologic options, and in particular, risperidone, were prioritized following the assessment of underlying causes. Two tailored non-drug approaches (DICE and music therapy) were agreed upon as the most promising non-pharmacologic treatment approaches for BPSD overall and agitation, with dextromethorphan/quinidine as a promising potential pharmacologic candidate for agitation. Regarding future treatments for psychosis, the greatest priority was placed on pimavanserin. CONCLUSIONS: This international consensus panel provided clear suggestions for potential refinement of current treatment criteria and prioritization of emerging therapies.

RESUMEN

BACKGROUND: Bright light treatment is a therapeutic intervention mainly used to treat sleep and circadian disturbances in Alzheimer's disease (AD) patients. Recently, a handful of studies also focused on the effect on cognition and behavior. Conflicting findings are reported in the literature, and no definite conclusions have been drawn about its specific therapeutic effect. SUMMARY: The aim of this review is to provide a critical evaluation of available evidence in this field, highlighting the specific characteristics of effective bright light treatment. Eligible studies were required to assess at least one of the following outcome measures: sleep, cognition, mood, and/or behavior (e.g., depression, agitation). A total of 32 articles were included in this systematic review and identified as research intervention studies about light treatment in AD. The quality of the papers was evaluated based on the US Preventive Service Task Force guidelines. Key Messages: Overall, the current literature suggests that the effects of light treatment in AD patients are mixed and may be influenced by several factors, but with a general trend toward a positive effect. Bright light seems to be a promising intervention treatment without significant adverse effects; therefore, further well-designed randomized controlled trials are needed taking into account the highlighted recommendations.

RESUMEN

BACKGROUND: Repetitive mild traumatic brain injuries (rmTBI) are associated with cognitive deficits, inflammation, and stress-related events. We tested the effect of nutrient intake on the impact of rmTBI in an animal model of chronic traumatic encephalopathy (CTE) to study the pathophysiological mechanisms underlying this model. We used a between group design rmTBI closed head injuries in mice, compared to a control and nutrient-treated groups. METHODS: Our model allows for controlled, repetitive closed head impacts to mice. Briefly, 24-week-old mice were divided into five groups: control, rmTBI, and rmTBI with nutrients (2% of NF-216, NF-316 and NF-416). rmTBI mice received four concussive impacts over 7 days. Mice were treated with NutriFusion diets for 2 months prior to the rmTBI and until euthanasia (6 months). Mice were then subsequently euthanized for macro- and micro-histopathologic analysis for various times up to 6 months after the last TBI received. Animals were examined behaviorally, and brain sections were immunostained for glial fibrillary acidic protein (GFAP) for astrocytes, iba-1 for activated microglia, and AT8 for phosphorylated tau protein. RESULTS: Animals on nutrient diets showed attenuated behavioral changes. The brains from all mice lacked macroscopic tissue damage at all time points. The rmTBI resulted in a marked neuroinflammatory response, with persistent and widespread astrogliosis and microglial activation, as well as significantly elevated phospho-tau immunoreactivity to 6 months. Mice treated with diets had significantly reduced inflammation and phospho-tau staining. CONCLUSIONS: The neuropathological findings in the rmTBI mice showed histopathological hallmarks of CTE, including increased astrogliosis, microglial activation, and hyperphosphorylated tau protein accumulation, while mice treated with diets had attenuated disease process. These studies demonstrate that consumption of nutrient-rich diets reduced disease progression.

RESUMEN

BACKGROUND: Multisensory stimulation and individualized music have shown to be good in handling the psychological and behavioral symptoms in people with severe dementia. OBJECTIVE: Explore the effects of two nonpharmacological interventions, multisensory stimulation environment (MSSE) in a Snoezelen room and individualized music sessions, on mood, behavior, and biomedical parameters of institutionalized elderly patients with severe dementia. METHODS: Randomized trial of 21 patients aged ≥65 years randomly assigned to two groups (MSSE and individualized music). Interventions administered in two-weekly sessions lasted 30 minutes for a period of 12 weeks. Main outcomes were recorded before, during, and at the end of the intervention. RESULTS: Both groups had immediate positive effects on mood and behavior. Participants were more happy/more content (p < 0.001), talked more spontaneously (p = 0.009), related to people better (p = 0.002), were more attentive to/focused on their environment (p < 0.001), enjoyed themselves (p = 0.003), were less bored/inactive (p = 0.004), and more relaxed/content (p = 0.003). The MSSE group performed a better visual follow-up of the stimuli (p = 0.044), and the music group were more relaxed and happy (p = 0.003). A decrease in heart rate (p = 0.013) and an increase in oxygen saturation (p = 0.011) were observed from before to after interventions in both groups, with no significant differences between them. CONCLUSIONS: Both interventions seem to be effective at managing mood and behavioral disturbances in the short term and at improving physiological rates, highlighting the efficacy of nonpharmacological treatments in patients with severe dementia.

RESUMEN

The publication of four papers concerning non-pharmacological interventions for persons with dementia heralds progress in the science of dementia care. The four papers are very diverse in focus and methodology, and include a study of the impact of a visual arts program on quality of life, communication, and well-being by Windle et al. (2017); an overview of systematic reviews of pharmacological and non-pharmacological interventions for the treatment of behavioral and psychological symptoms of dementia by Dyer et al. (2017); a systematic review of the efficacy of intervention in people with Lewy body dementia by Morrin et al. (2017); and a protocol of the Behavior and Evolution of Young Onset Dementia part two (BEYOND-II) study, an intervention study aimed at improvement in the management of neuropsychiatric symptoms in institutionalized people with young onset dementia by van Duinen-van den IJssel et al. (2017).

RESUMEN

Background and Objectives: To draw from systematic and other literature reviews to identify, describe, and critique nonpharmacological practices to address behavioral and psychological symptoms of dementia (BPSDs) and provide evidence-based recommendations for dementia care especially useful for potential adopters. Research Design and Methods: A search of systematic and other literature reviews published from January 2010 through January 2017. Nonpharmacological practices were summarized to describe the overall conceptual basis related to effectiveness, the practice itself, and the size and main conclusions of the evidence base. Each practice was also critically reviewed to determine acceptability, harmful effects, elements of effectiveness, and level of investment required, based on time needed for training/implementation, specialized care provider requirements, and equipment/capital requirements. Results: Nonpharmacological practices to address BPSDs include sensory practices (aromatherapy, massage, multi-sensory stimulation, bright light therapy), psychosocial practices (validation therapy, reminiscence therapy, music therapy, pet therapy, meaningful activities), and structured care protocols (bathing, mouth care). Most practices are acceptable, have no harmful effects, and require minimal to moderate investment. Discussion and Implications: Nonpharmacological practices are person-centered, and their selection can be informed by considering the cause and meaning of the individual's behavioral and psychological symptoms. Family caregivers and paid care providers can implement evidence-based practices in home or residential care settings, although some practices require the development of more specific protocols if they are to become widely used in an efficacious manner.

RESUMEN

BACKGROUND: Problem behaviours (PBs) are a common cause for clinician contact in people with disorders of intellectual development and may be a common cause for the prescription of psychotropic medication. We aimed to use a large, multinational sample to define the prevalence of PBs, the associations with psychotropic medication use, and to assess for any potential 'diagnostic overshadowing' by the label of PBs in a population of people with disorders of intellectual development. METHOD: A multinational, multi-setting, cross-sectional service evaluation and baseline audit was completed. Data were collected from UK hospitals, UK community settings, Sri Lanka and Hong Kong. A semi-structured questionnaire was completed by treating clinicians, capturing demographic details, prevalence rates of intellectual disability and psychotropic medication use, alongside psychiatric co-morbidity. RESULTS: A sample size of 358 was obtained, with 65% of included participants treated in an inpatient setting. Psychotropic use was prevalent (90%) in our sample, particularly antipsychotics (74%). The prevalence of PB was high (83%). There was no statistically significant association between psychotropic prescription and recorded psychiatric co-morbidity, suggesting prevalent 'off-label' use for PBs, or poor recording of psychiatric co-morbidity. There was some evidence of possible diagnostic overshadowing due to the PB classification. A higher dose of psychotropic medication was associated with aggression toward others (P = 0.03). CONCLUSIONS: We found evidence of prevalent potential 'off-label' use for psychotropic medication, which may be due to PBs. We also found evidence of potential diagnostic-overshadowing, where symptoms of psychiatric co-morbidity may have been attributed to PBs. Our findings provide renewed importance, across borders and health systems, for clinicians to consider a holistic approach to treating PBs, and attempting to best understand the precipitants and predisposing factors before psychotropic prescribing.

RESUMEN

Background and Objectives: To avoid "chemical restraints," policies and guidelines have been implemented to curb the use of medications for behavioral and psychological symptoms of dementia (BPSD). Antipsychotics have been particularly targeted because of their rare severe side effects. Consequently, caregiver directed non-pharmacologic therapies have increased while medication use for BPSD has diminished. Despite such initiatives, however, antipsychotics continue to be prescribed "off-label" for roughly 20% of nursing home patients. How caregivers impact management approaches and prescribing decisions for BPSD, including antipsychotic use, is poorly understood. Aim: assesses experiences and perceptions of family and nursing caregivers regarding factors influencing medication decisions for BPSD. Research Design and Methods: Semi-structured interviews, analyzed via template, immersion and crystallization, and thematic development. Thirty-two participants from Northwestern Virginia representing five groups of caregivers for dementia patients were interviewed: families of community-dwelling, assisted living, and nursing home patients, and nurses from the same assisted living/nursing home facilities. Results: Caregivers described three major themes regarding medications: (a) Systemic barriers exist for non-pharmacologic BPSD therapies. (b) Medications have few barriers, and seem generally effective and safe. (c) When non-pharmacologic measures fail, medications, including antipsychotics, may be necessary and appropriate for palliation of patient distress. Discussion and Implications: To further reduce medications for BPSD, obstacles to services and alternative therapies must be mitigated. Caregiver perceptions that medications are generally safe and effective contribute to their continued use. Guidelines and policies for BPSD management should incorporate the caregiver position that medications, including antipsychotics, are sometimes justified and required to alleviate patient suffering.

RESUMEN

BACKGROUND: Men with biochemical recurrence of prostate cancer following local therapies often use natural supplements in an attempt to delay metastases and/or avoid the need for more aggressive treatments with undesirable side-effects. While there is a growing body of research into phytotherapeutic agents in this cohort, with some promising results, as yet no definitive recommendations can be made. This pilot study was undertaken to assess the feasibility of a fully-powered study to examine the effects of this phytotherapeutic intervention (containing turmeric, resveratrol, green tea and broccoli sprouts) on PSA doubling time in men with biochemical recurrence with a moderate PSA rise rate. METHODS: A double blind, randomized, placebo-controlled parallel trial was conducted with 22 men with biochemically recurrent prostate cancer and a moderate rise rate (PSA doubling time of 4-15 months and no evidence of metastases from conventional imaging methods). Patients were randomized to either the active treatment arm or placebo for 12 weeks. The primary endpoints were feasibility of study recruitment and procedures, and measurement of proposed secondary endpoints (prostate symptoms, quality of life, anxiety, and depression as measured on the EORTC QLQ-C30 and PR-25, the IPSS and HADS). Data were collected to estimate PSA-log slopes and PSA-doubling times, using a mixed model, for both the pre-intervention and post-intervention periods. RESULTS: Adherence to study protocol was excellent, and the phytotherapeutic intervention was well-tolerated, with similar numbers of mild-to-moderate adverse events in the active and placebo arms. Both the intervention and data collection methods were acceptable to participants. No statistical difference between groups on clinical outcomes was expected in this pilot study. There was between-subject variation in the PSA post treatment, but on average the active treatment group experienced a non-significant increase in the log-slope of PSA (pre-treatment doubling time = 10.2 months, post-treatment doubling time = 5.5 months), and the placebo group experienced no change in the log-slope of PSA (pre-treatment doubling time = 10.8 months, post-treatment doubling time = 10.9 months). CONCLUSION: The findings suggest that a fully powered study of this combination is feasible in men with biochemically recurrent prostate cancer and a moderate PSA rise rate.
