RESUMO
BACKGROUND AND RATIONALE: SPECAL is a model of care for people with dementia based on a novel conceptualisation of memory and how this changes in dementia. Carers adapt their communication style to prevent distress and promote well-being for the person with dementia. However, there is limited scientific evidence on the effectiveness of SPECAL. AIM: This study explored mechanisms of SPECAL through a qualitative enquiry with family carers. METHOD: Semi-structured interviews were conducted with family carers who had been coached in SPECAL and applied its principles and practices. Thematic analysis was applied. FINDINGS: All participants had found SPECAL helpful in caring for a person with dementia. The core themes of this positive experience were empathy, harmony and resilience. Synthesis of these themes contributes to a proposed model of the mechanisms of SPECAL. CONCLUSION: In applying SPECAL, carers gained an empathetic insight to the feelings of the person with dementia. This empathy leads to a more harmonious environment, which enhances the carer's resilience.

Cornelia de Lange syndrome (CdLS) is a multisystem genetic disorder associated with unusual facial features, limb abnormalities, a wide range of health conditions, and intellectual disability. Mutations in five genes that encode (SMC1A, SMC3, RAD21) or regulate (NIPBL, HDAC8) the cohesin complex have been identified in up to 70% of individuals. Genetic cause remains unknown for a proportion of individuals. There is substantial heterogeneity in all aspects of CdLS but very little is known about what predicts phenotypic heterogeneity. In this study, we evaluated genotype-phenotype associations in 34 individuals with CdLS. Participants with NIPBL mutations had significantly lower self help skills and were less likely to have verbal skills relative to those who were negative for the NIPBL mutation. No significant differences were identified between the groups in relation to repetitive behavior, mood, interest and pleasure, challenging behavior, activity, impulsivity, and characteristics of autism spectrum disorder whilst controlling differences in self help skills. Significant correlations indicating lower mood, interest and pleasure, and increased insistence on sameness with older age were identified for those who were NIPBL mutation positive. The findings suggest similarities in the behavioral phenotype between those with and without the NIPBL mutation once differences in self help skills are controlled for. However, there may be subtle differences in the developmental trajectory of these behaviors according to genetic mutation status in CdLS.

A small number of recent papers have described individuals with intellectual disabilities and microdeletions in chromosome band 19p13.2. However, little is known about the behavioral characteristics of individuals with microdeletions in this area. The current study examines behavioral characteristics of a series of 10 participants ranging in age from 2 to 20 years with 19p13.2 microdeletions. Parents/caregivers completed a series of established behavioral measures which have aided the elucidation of the behavioral phenotypes of a number of genetic neurodevelopmental syndromes. All but the youngest two participants (aged 2 and 3 years) were verbal, ambulant, and classified as "partly able" or "able" with regard to self-help skills. Six of eight participants for whom a screening measure for autism spectrum disorders (ASD) could be deployed met criteria for an ASD. Six of the 10 participants had displayed self-injurious behavior in the month prior to assessment, eight had displayed destruction/disruption of property, and eight had shown physically aggressive behaviors. Repetitive behaviors were prevalent in the sample (with all participants displaying at least one repetitive behavior to a clinically relevant level), as were problems with sleep. Low mood was not prevalent in this group, and nor were overactivity or impulsivity. Full determination of a behavioral phenotype for this group would require a larger sample size, distinguishing between genetic subtypes. However, the current data suggest that ASD characteristics, repetitive, and challenging behaviors (such as aggression and self-injury) might be associated with 19p13.2 microdeletions, providing a basis for future investigation.
