Neuropsychiatric Symptom Burden across Neurodegenerative Disorders and its Association with Function.

OBJECTIVE: Neuropsychiatric symptoms (NPS) are prevalent in neurodegenerative disorders, however, their frequency and impact on function across different disorders is not well understood. We compared the frequency and severity of NPS across Alzheimer's disease (AD) (either with mild cognitive impairment or dementia), Cerebrovascular disease (CVD), Parkinson's disease (PD), frontotemporal dementia (FTD), and amyotrophic lateral sclerosis (ALS), and explored the association between NPS burden and function. METHODS: We obtained data from Ontario Neurodegenerative Disease Research Initiative (ONDRI) that included following cohorts: AD (N = 111), CVD (N = 148), PD (N = 136), FTD (N = 50) and ALS (N = 36). We compared the frequency and severity of individual NPS (assessed by the neuropsychiatric inventory questionnaire) across cohorts using generalized estimating equations and analysis of variance. Second, we assessed the relationship of NPS burden with instrumental (iADLs) and basic (ADLs) activities of living across cohorts using multivariate linear regression while adjusting for relevant demographic and clinical covariates. RESULTS: Frequency of NPS varied across cohorts (χ2(4) = 34.4, p < .001), with post-hoc tests showing that FTD had the greatest frequency as compared to all other cohorts. The FTD cohort also had the greatest severity of NPS (H(4) = 34.5, p < .001). Further, there were differences among cohorts in terms of the association between NPS burden and ADLs (F(4,461) = 3.1, p = 0.02). Post-hoc comparisons suggested that this finding was driven by the FTD group, however, the differences did not remain significant following Bonferroni correction. There were no differences among cohorts in terms of the association between NPS burden and IADLs. CONCLUSIONS: NPS frequency and severity are markedly greater in FTD as compared to other neurodegenerative diseases. Further, NPS burden appears to be associated differently with function across neurodegenerative disorders, highlighting the need for individualized clinical interventions.

Tele-Mindfulness for Dementia's Family Caregivers: A Randomized Trial with a Usual Care Control Group.

BACKGROUND: Caring for a family member with dementia is stressful and challenging. Family caregivers, as a vulnerable marginalized population and invisible backbone of the health care system, need accessible and effective interventions that are tailored to their particular needs. OBJECTIVES: The objective of this study was to evaluate the feasibility and effectiveness of a live online mindfulness-based cognitive therapy (tele-MBCT) intervention for family caregivers of individuals with dementia. METHODS: Family caregivers were assigned to a tele-MBCT intervention or a usual care control group. Tele-MBCT participants attended eight weekly live online training and practiced mindfulness practices at home. All participants completed surveys at baseline, post-intervention, and 4-week follow-up. RESULTS: 26 participants (age 60±13 years) were enrolled and randomized (14 in the intervention and 12 in the control group), and 92.3% completed the study. 88% of the participants were female, and 70% were caring for a parent for a mean of 5.12±2.88 years. 84% of the participants in the intervention group attended at least seven sessions and the average of daily practice was 23.58±45.71 minutes. All participants were satisfied with the intervention, and 88.8% were satisfied with the online delivery method. Participants in the intervention group showed Pre-Post improvement in self-compassion (t (11) = -2.49, p=0.03) and coping strategies (t (11) = 3.62, p=0.004) compared to the control group. CONCLUSION: Tele-MBCT is a feasible intervention and may improve psychological outcomes and adaptive coping in family caregivers of individuals with dementia. A larger controlled trial is warranted.

The Rationale and Design of Behavioral Interventions for Management of Agitation in Dementia in a Multi-Site Clinical Trial.

BACKGROUND: Agitation and aggression are common in patients with Alzheimer's disease and related dementias and pose a significant burden on patients, caregivers, and the healthcare systems. Guidelines recommend personalized behavioral interventions as the first-line treatment; however, these interventions are often underutilized. The Standardizing Care for Neuropsychiatric Symptoms and Quality of Life in Dementia (StaN) study (ClinicalTrials.gov Identifier # NCT0367220) is a multisite randomized controlled trial comparing an Integrated Care Pathway, that includes a sequential pharmacological algorithm and structured behavioral interventions, with treatment-as-usual to treat agitation in dementia in long-term care and inpatient settings. OBJECTIVE: To describe the rationale and design of structured behavioral interventions in the StaN study. METHODS: Structured behavioral interventions are designed and implemented based on the following considerations: 1) personalization, 2) evidence base, 3) dose and duration, 4) measurement-based care, and 5) environmental factors and feasibility. RESULTS: The process to design behavioral interventions for each individual starts with a comprehensive assessment, followed by personalized, evidence-based interventions delivered in a standardized manner with ongoing monitoring of global clinical status. Measurement-based care is used to tailor the interventions and integrate them with pharmacotherapy. CONCLUSION: Individualized behavioral interventions in patients with dementia may be challenging to design and implement. Here we describe a process to design and implement individualized and structured behavioral interventions in the context of a multisite trial in long-term care and inpatient settings. This process can inform the design of behavioral interventions in future trials and in clinical settings for the treatment of agitation in dementia.

Parathyroid Hormone Levels May Predict Nonalcoholic Steatohepatitis in Morbidly Obese Patients.

BACKGROUND: Obesity as a worldwide health problem is associated with nonalcoholic steatohepatitis (NASH). Since severe liver injury may be present in asymptomatic obese patients and a definite diagnosis of nonalcoholic steatohepatitis can only be made after an invasive procedure of liver biopsy, there is a need for noninvasive methods to predict the probability of NASH. OBJECTIVES: To investigate the role of vitamin D endocrine system in predicting the probability of presence of NASH in asymptomatic morbidly obese candidates of bariatric surgery. PATIENTS AND METHODS: From December 09 to March 11, every patient undergoing bariatric surgery had a liver biopsy. Nonalcoholic steatohepatitis was diagnosed using the Lee's criteria, the baseline labs obtained and the association between laboratory data and presence of NASH assessed. RESULTS: Forty-six patients (34 women, aged 36.5 ± 10.6 years) were analyzed. The mean levels of liver enzymes were significantly higher in the group with NASH (P value < 0.01). In an unadjusted logistic model, PTH was the only variable in vitamin D endocrine system which was significantly associated with NASH (odds ratio (OR): 1.04, 95%CI: 1.01 - 1.07). After adjustment for possible confounding factors, age (OR: 1.22, 95%CI: 1.00 - 1.50) and PTH (OR: 1.08, 95%CI: 1.01 - 1.16) were predictive factors for NASH (P value < 0.05). CONCLUSIONS: Elevated serum PTH level was the predictive factor for NASH in morbidly obese patients. Also, we reported elevated serum liver enzymes, high serum PTH levels and older age as predictors of NASH in patients seeking obesity surgical treatments.
