Use of Robotic Pet in a Distributed Layout Elderly Housing with Services: A Case Study on Elderly People with Cognitive Impairment

In recent years, robotic pets have been used by many countries worldwide as a method for treating behavioral and psychological symptoms of dementia (BPSD). The seal robot PARO was loaned intermittently to a distributed layout elderly housing with services over a seven-month period, during which it was observed that three residents with cognitive dysfunctions showed improvements in their BPSD and the nursing care load of the staff was reduced during the periods when PARO was present. The objective of this study is to investigate, through a case study, the effects of intermittent interaction with PARO on those with cognitive dysfunctions and the staff workers. The short version of the Dementia Behavior Disturbance Scale (DBD-13) was used as the medical outcome index, and the KJ method was used to analyze the qualitative data, such as staff reports and interviews. The results show that the DBD-13 total scores reduced during the periods when PARO was present and increased during the periods when PARO was absent. The KJ method yielded similar findings. The use of DBD-13 and the KJ method complemented the results of each other and increased the persuasive power of the findings. By using the KJ method, it was further determined that the workload of the staff was reduced, allowing them to recuperate, which reconfirmed the value of PARO. Further case studies will be undertaken in the future with the aim of constructing a methodology for implementing case studies.

Verification of Trail Making Test in Elderly People with Behavioral and Psychological Symptoms of Dementia

In Alzheimer's disease (AD), attention and executive dysfunction occur early in the disease. However, little is known about the relationship between these disorders and behavioral and psychological symptoms of dementia (BPSD). This study investigated the relationship between BPSD and attention and execution functions. Twenty-five patients with mild cognitive impairment (MCI) and early AD were included. Neuropsychological tests, mini-mental state examination (MMSE), Raven’s colored progressive materials (RCPM), and trail making test (TMT) were conducted for patients with dementia. The dementia behavior disturbance scale (DBD) was used for psychological and behavioral evaluations of patients with dementia. The AD group showed significantly lower MMSE, DBD, and TMT-B scores than the MCI group. Multiple regression analyses revealed a significant correlation between DBD score, MMSE, and TMT-B.Conclusion: BPSD is associated with cognitive function severity in patients with MCI and early AD, suggesting that attentional and executive functions are independent risk factors for these neural substrates.

Exploring the Interactions Between Neurophysiology and Cognitive and Behavioral Changes Induced by a Non-pharmacological Treatment: A Network Approach

Dementia due to Alzheimer’s disease (AD) is a neurological syndrome which has an increasing impact on society, provoking behavioral, cognitive, and functional impairments. AD lacks an effective pharmacological intervention; thereby, non-pharmacological treatments (NPTs) play an important role, as they have been proven to ameliorate AD symptoms. Nevertheless, results associated with NPTs are patient-dependent, and new tools are needed to predict their outcome and to improve their effectiveness. In the present study, 19 patients with AD underwent an NPT for 83.1 ± 38.9 days (mean ± standard deviation). The NPT was a personalized intervention with physical, cognitive, and memory stimulation. The magnetoencephalographic activity was recorded at the beginning and at the end of the NPT to evaluate the neurophysiological state of each patient. Additionally, the cognitive (assessed by means of the Mini-Mental State Examination, MMSE) and behavioral (assessed in terms of the Dementia Behavior Disturbance Scale, DBD-13) status were collected before and after the NPT. We analyzed the interactions between cognitive, behavioral, and neurophysiological data by generating diverse association networks, able to intuitively characterize the relationships between variables of a different nature. Our results suggest that the NPT remarkably changed the structure of the association network, reinforcing the interactions between the DBD-13 and the neurophysiological parameters. We also found that the changes in cognition and behavior are related to the changes in spectral-based neurophysiological parameters. Furthermore, our results support the idea that MEG-derived parameters can predict NPT outcome; specifically, a lesser degree of AD neurophysiological alterations (i.e., neural oscillatory slowing, decreased variety of spectral components, and increased neural signal regularity) predicts a better NPT prognosis. This study provides deeper insights into the relationships between neurophysiology and both, cognitive and behavioral status, proving the potential of network-based methodology as a tool to further understand the complex interactions elicited by NPTs.

Neuropsychiatric Symptoms of Alzheimer’s Disease in Down Syndrome and Its Impact on Caregiver Distress

Background: Neuropsychiatric symptoms (NPS) are non-cognitive manifestations common to dementia and other medical conditions, with important consequences for the patient, caregivers, and society. Studies investigating NPS in individuals with Down syndrome (DS) and dementia are scarce. Objective: Characterize NPS and caregiver distress among adults with DS using the Neuropsychiatric Inventory (NPI). Methods: We evaluated 92 individuals with DS (≥30 years of age), divided by clinical diagnosis: stable cognition, prodromal dementia, and AD. Diagnosis was determined by a psychiatrist using the Cambridge Examination for Mental Disorders of Older People with Down’s Syndrome and Others with Intellectual Disabilities (CAMDEX-DS). NPS and caregiver distress were evaluated by an independent psychiatrist using the NPI, and participants underwent a neuropsychological assessment with Cambridge Cognitive Examination (CAMCOG-DS). Results: Symptom severity differed between-groups for delusion, agitation, apathy, aberrant motor behavior, nighttime behavior disturbance, and total NPI scores, with NPS total score being found to be a predictor of AD in comparison to stable cognition (OR for one-point increase in the NPI = 1.342, p = 0.012). Agitation, apathy, nighttime behavior disturbances, and total NPI were associated with CAMCOG-DS, and 62% of caregivers of individuals with AD reported severe distress related to NPS. Caregiver distress was most impacted by symptoms of apathy followed by nighttime behavior, appetite/eating abnormalities, anxiety, irritability, disinhibition, and depression (R2 = 0.627, F(15,76) = 8.510, p < 0.001). Conclusion: NPS are frequent and severe in individuals with DS and AD, contributing to caregiver distress. NPS in DS must be considered of critical relevance demanding management and treatment. Further studies are warranted to understand the biological underpinnings of such symptoms.

Association between Daily Activities and Behavioral and Psychological Symptoms of Dementia in Community-Dwelling Older Adults with Memory Complaints by Their Families

It is important and useful to consider information provided by family members about individuals with memory complaints’ instrumental activities of daily living (IADL). The purpose of this study was to clarify the characteristics and relevance of individuals with memory complaints’ IADL and behavioral and psychological symptoms of dementia (BPSD) assessed from the perspective of the family members using the Process Analysis of Daily Activity for Dementia and short version Dementia Behavior Disturbance scale. A self-administered questionnaire was sent to 2000 randomly selected members of Consumer’s Co-operative Kagoshima, and 621 responded. Of the returned responses, there were 159 participants who answered about individuals with memory complaints. The stepwise multiple regression analysis was used to examine the association between IADL and BPSD. The result showed that many IADL of the individuals with memory complaints were associated with BPSD of apathy, nocturnal wakefulness, and unwarranted accusations, adjusted for age, gender, and the observation list for early signs of dementia. In addition, each IADL was associated with BPSD of apathy, nocturnal wakefulness, and dresses inappropriately. Modifying lifestyle early on when families recognize these changes may help maintain and improve the long-term quality of life of the individuals with memory complaints and their family.

Self-destructive behavior in patients with psychotic disorders of the schizophrenia spectrum

The present study assesses the peculiarities and the pathways of self-destructive behavior (SDB) and self-injury acts (SI) in a group of inpatients who have schizophrenia spectrum psychotic disorders (SSPsD). They were 77 patients with schizophrenia, schizoaffective disorder and acute polymorphic psychotic disorder examined in this issue and divided into 2 groups according to the pathways types of SDB: the first group — patients with permanent peculiarities of SDB as comorbid disturbance (Gr1 PermSDB), the second group — patients with impulsive SDB manifestations as secondary behavior disturbance on background acute psychotic episode with imperative pseudo-hallucinations (Gr2 ImpSI) There was a weighty predominance of patients with schizophrenia and hallucinatory-paranoid syndrome in both groups. Patients with schizophrenia more frequently realized impulsive SI exactly with imperative pseudo-hallucinations as the cause of them. Significant difference in motivation of SDB and SI was found in different groups. In Gr1 PermSDB the main motivation was psychological problems associated with mental illness, social and interpersonal problems, while in Gr2 ImpSI the exclusive reason of SI was «command» to do it under influence of imperative pseudo-hallucinations. The psychometric results (the Plutchik’s impulsivity scale) revealed a much higher level of impulsivity in Gr1 PermSDB. Results confirmed that fundamentally diverse pathways for SDB manifestation and dynamic of it, also SI motivation exist in patients with SSPsD. It should be taken in the treatment tactic and rehabilitation course for such different patients. Key words: self-destructive behaviour, self-injury, psychotic disorders of the schizophrenia spectrum

A Causal Model of Caregiving Burden among Dementia Caregivers

In this study, a cross-sectional, predictive correlation design was used to identify and test a causal relationship between behavior disturbances, coping, family conflict, self-esteem and social support to caregiver burden among dementia caregivers. A total of 450 caregivers of dementia aged over 18 years were recruited from 4 hospitals in northern Thailand based on selected criteria. Demographic Questionnaire, Behavioral Pathology in Alzheimer’s Disease Rating Scale (BEHAVE-AD, The Family Conflict Scale, The Zarit Burden Interview Scale, The Perceived Social Support Questionnaire, The Brief COPE and The Rosenberg Self-Esteem with acceptable reliability coefficients were used to collect data. Data were analyzed using descriptive statistics, Pearson’s Product-Moment Correlation and path analysis by structural equation modeling. Results showed that the modified model fitted with the data and explained 58 % of the variance in caregiving burden among dementia caregivers. Coping and family conflict had a positive direct effect on caregiving burden (p < 0.001), whereas self-esteem and social support had a direct negative effect on caregiving burden (p < 0.001). Behavior disturbance had a positive indirect effect caregiving burden (p < 0.001) via family conflict. Coping had a positive indirect effect on caregiving burden (p < 0.001) via behavior disturbance and family conflict. Social support had a negative indirect effect on caregiving burden (p < 0.001) via family conflict and self-esteem. The results of this study could be used as a guideline for psychiatric nurses in planning an appropriate intervention program to reduce burden of caregivers of dementia patients in Thailand.

Violent behaviors conducted by children were unimaginable by our mind that we have set our mind that children are group of people who still innocent, and the hope for our future. Violence—in our mind—is perhaps the trait that labeled to some thugs, robbers, and many criminals whose world are full of violence they lived in. What is happening with our society and our children? Violence conducted by children can be seen as social behavior disturbance since there are violations to the moral values and humanity, family and society normative rules. Violent behavior—verbal and non verbal—including bad attitudes and behaviors that disturb many our environment are violation to what we call as society norms and laws. Children who conducted violent behavior were not a result of instant process but a cumulative result of many aspects they have seen, heard and felt in daily life. Aggression and anti social behavior are a learned behavior which means that children learned it from imitation process from something and someone who they meet, see, heard and copied.
