Behavioral and Psychological Symptoms of Dementia
Key to the experience of some adults with dementia is expressions of various behaviors that may had not been part of that person’s life. Generally, termed behavioral and psychological symptoms of dementia (BPSD), they may include agitation, depression, apathy, repetitive questioning, psychosis, aggression, sleep problems, wandering, and a variety of inappropriate behaviors. Some examples of agitation include physical or verbal aggression, general emotional distress, restlessness, pacing, shredding paper or tissues and/or yelling). At times delusions (firmly held belief in things that are not real) and hallucinations (seeing, hearing or feeling things that are not there) may also be present. The Alzheimer’s Association (US) notes that are potential causes (stimulants) for behavioral and psychiatric symptoms including one of more of the following:
-
Pain, or an underlying infection or medical illness (injury, urinary tract infection, ear infection, pneumonia, etc.)
-
Prescription drug interactions
-
Moving to a new residence
-
Changes in the environment or caregiver arrangements
-
Misperceived threats
-
Fear and fatigue resulting from trying to make sense out of a confusing world.
-
Uncorrected visual or hearing loss
-
Hospitalization
-
Bathing
-
Being asked to do something that has become difficult due to the person’s declining cognitive skills
BPSDs are found in adults with intellectual disability living with dementia and often the same techniques that are applied with adults in the general population will apply with regard to non-pharmacological interventions with adults with intellectual disability.
In this resource section we include a curated listing of guides and reports from the literature that reference BPSDs in general and those that apply to adults with intellectual disability.

Assessment and Management of People with Behavioural and Psychological Symptoms of Dementia (BPSD)
This Australian practical handbook is a reference for health staff working in settings where they will care for people with dementia and BPSD. The handbook presupposes that a person with dementia and behavioral disturbance may be viewed as ‘a difficult or disruptive person’, particularly if the clinician has little experience in this area. Although the behavior may be challenging, the person is unwell and
requires care. The key principles for providing care are: 1. Person-centered care (emphasizing understanding the person, not the behavior or disease to be ‘‘managed’’); Multidisciplinary and multi-team care (clinical challenges requiring expertise from different health professions); and 3. Legal and ethical responsibilities (diminished capacity for consent forces health professionals to consider ethical and legal challenges).

Neuropsychiatric symptoms of Alzheimer’s disease in Down syndrome and its impact on caregiver distress
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.

Prevalence of behavioural and psychological symptoms of dementia in individuals with learning disabilities
A review of 23 studies investigating the prevalence of behavioral and psychological symptoms of dementia (BPSD) in the general and intellectual disability population and measures used to assess BPSD was carried out. BPSD are non-cognitive symptoms, which constitute as a major component of dementia regardless of its subtype. Research has indicated that there is a high prevalence of BPSD in the general dementia population. There are limited studies, which investigate the prevalence of BPSD within individuals who have intellectual disabilities and dementia. Findings suggest BPSDs are present within individuals with intellectual disabilities and dementia. Future research should use updated tools for investigating the prevalence of BPSD within individuals with intellectual disabilities and dementia.

The Behavioral and Psychological Symptoms of Dementia in Down Syndrome (BPSD-DS) Scale: Comprehensive assessment of psychopathology in Down syndrome
People with Down syndrome (DS) are prone to develop Alzheimer’s disease (AD). Behavioral and psychological symptoms of dementia (BPSD) are core features, but have not been comprehensively evaluated in DS. In a European multidisciplinary study, the novel Behavioral and Psychological Symptoms of Dementia in Down Syndrome (BPSD-DS) scale was developed to identify frequency and severity of behavioral changes taking account of life-long characteristic behavior. 83 behavioral items in 12 clinically defined sections were evaluated. The central aim was to identify items that change in relation to the dementia status, and thus may differentiate between diagnostic groups. Structured interviews were conducted with informants of persons with DS without dementia (DS, n = 149), with questionable dementia (DS+Q, n = 65), and with diagnosed dementia (DS+AD, n = 67). First exploratory data suggest promising interrater, test-retest, and internal consistency reliability measures. Concerning item relevance, group comparisons revealed pronounced increases in frequency and severity in items of anxiety, sleep disturbances, agitation & stereotypical behavior, aggression, apathy, depressive symptoms, and eating/drinking behavior. The proportion of individuals presenting an increase was highest in DS+AD, intermediate in DS+Q, and lowest in DS. Interestingly, among DS+Q individuals, a substantial proportion already presented increased anxiety, sleep disturbances, apathy, and depressive symptoms, suggesting that these changes occur early in the course of AD. Future efforts should optimize the scale based on current results and clinical experiences, and further study applicability, reliability, and validity. Future application of the scale in daily care may aid caregivers to understand changes, and contribute to timely interventions and adaptation of caregiving.

(2010).L'échelle d'évaluation de l'inventaire neuropsychiatrique du clinicien (NPI-C): fiabilité et validité d'une évaluation révisée des symptômes neuropsychiatriques de la démence.Psychogériatrie internationale, 22(6), 984–994.https://doi.org/10.1017/S1041610210000876
Les symptômes neuropsychiatriques (SNP) affectent presque tous les patients atteints de démence et constituent un axe majeur d'étude et de traitement. Une évaluation précise du NPS par le biais de mesures valides, sensibles et fiables est cruciale. Bien que les mesures actuelles du NPS présentent de nombreux atouts, elles présentent également certaines limites (par exemple, l'acquisition de données est limitée aux informateurs ou aux soignants en tant que répondants, profondeur limitée des éléments spécifiques à la démence modérée). Par conséquent, nous avons développé une version révisée du NPI, connue sous le nom de NPI-C. Le NPI-C comprend des domaines et des éléments élargis, ainsi qu'une méthodologie d'évaluation des cliniciens. Cette étude a évalué la fiabilité et la validité convergente du NPI-C sur dix sites internationaux (sept langues). La validité apparente de 78 nouveaux items a été obtenue grâce à un panel Delphi. Un total de 128 dyades (soignants/patients) de trois catégories de gravité de la démence (léger = 58, modéré = 49, sévère = 21) ont été interrogés séparément par deux évaluateurs formés en utilisant deux méthodes d'évaluation : l'entretien NPI original et un entretien évalué par un clinicien. méthode. L'évaluateur 1 a également administré quatre mesures supplémentaires établies : l'échelle d'évaluation de l'apathie, l'échelle d'évaluation psychiatrique brève, l'indice d'agitation de Cohen-Mansfield et l'échelle de Cornell pour la dépression dans la démence. Les corrélations intraclasse ont été utilisées pour déterminer la fiabilité inter-évaluateurs. Les corrélations de Pearson entre les quatre domaines NPI-C pertinents et leurs mesures externes correspondantes ont été utilisées pour la validité convergente. La fidélité inter-juges était forte pour la plupart des items. La validité convergente était modérée (apathie et agitation) à forte (hallucinations et délires ; agitation et vocalisations aberrantes ; et dépression) pour les évaluations des cliniciens dans les domaines NPI-C. Dans l'ensemble, le NPI-C est prometteur en tant qu'outil polyvalent qui peut mesurer avec précision le NPS et qui utilise un système d'échelle uniforme pour faciliter les comparaisons de données entre les études.
