Effects of an outdoor horticultural activities program on cognitive and behavioral functioning, mood, and perceived quality of life in people with dementia: a pilot study.

Introduction: One of various non-pharmacological treatments for people with dementia (PwD) is horticultural therapy. The aim of this double-blind, pre- and post-test, pilot study was to examine the effects of horticultural activities (HA) for PwD at a residential and daytime care facility. Whether combining HA with elements drawn from other psychosocial interventions (cognitive stimulation) would maximize any benefits was also newly examined. Materials and methods: Twenty-four PwD were involved either in HA, alone (TG1, N = 7) or combined with some cognitive stimulation (TG2, N = 8), or in indoor treatment-as-usual activities (CG, N = 9). Benefits were assessed in terms of general cognitive functioning (for participants with mild-to-moderate dementia), mood, behavioral and psychological symptoms, and quality of life. Results: No differences emerged between TG1 and TG2 in any outcome measure, so the two groups were combined (N = 15). Compared with the CG, the TG involved in HA exhibited less frequent and severe behavioral and psychological symptoms and an improved mood after the intervention. Caregivers also reported less distress in the TG after the intervention than in the CG. Considering only PwD with mild-to-moderate dementia, the TG also showed benefits in a measure of general cognitive functioning, and self-reported quality of life, compared with the CG. Discussion: Our results further confirm that engaging PwD in participatory HA in contact with natural elements can decrease their dementia symptoms and their caregivers' distress, but also increase PwD's quality of life. Our findings also suggest the need to consider dementia severity when assessing the benefits of horticultural therapy.

Psychological impacts of intervention to improve a therapeutic garden for older adults with dementia: a case study conducted at a care facility.

Introduction: Exposure to nature is known to support psychological wellbeing, and can support People with Dementia (PwD). Here we describe a case study conducted at a care facility for PwD to examine the effect of their exposure to nature after intervention to renovate an existing Therapeutic Garden (TG). Changes in frequency of attendance and behavior in the TG were examined. A single case was also considered to assess individual benefits. Materials and methods: Twenty-one PwD participated in the study. Their behavior in the TG was observed for 4 weeks before and after the intervention (using behavioral mapping), and measures of individual characteristics (general cognitive functioning, behavioral/neuropsychiatric symptoms, depression, and quality of life) were administered. Results: Ten of the 21 PwD visited the TG more often after the intervention, their social behaviors (e.g., talking to others) increased, and their active isolated behavior in the garden (e.g., smelling, touching flowers) tended to increase. The increase in social behavior related to less severe baseline depressive symptoms. Passive isolated behaviors related to more impaired baseline cognitive functioning. The case of Mrs. A extended the findings for the whole sample: although her dementia symptoms (apathy, motor disturbances) worsened, she visited the TG more often after the intervention, her social exchanges and active isolated actions increased, and her agitation and wandering decreased. Discussion: These results support the benefits of exposure to nature for PwD, and underscore the importance of considering users' profiles to optimize their use of a TG.

Validation of PARADISE 24 and Development of PARADISE-EDEN 36 in Patients with Dementia.

Dementia was one of the conditions focused on in an EU (European Union) project called "PARADISE" (Psychosocial fActors Relevant to brAin DISorders in Europe) that later produced a measure called PARADISE 24, developed within the biopsychosocial model proposed in the International Classification of Functioning Disability and Health (ICF). The aims of this study are to validate PARADISE 24 on a wider sample of patients with mild to moderate dementia to expand PARADISE 24 by defining a more specific scale for dementia, by adding 18 questions specifically selected for dementia, which eventually should be reduced to 12. We enrolled 123 persons with dementia, recruited between July 2017 and July 2019 in home care and long-term care facilities, in Italy, and 80 participants were recruited in Warsaw between January and July 2012 as part of a previous cross-sectional study. The interviews with the patient and/or family were conducted by health professionals alone or as a team by using the Paradise data collection protocol. The psychometric analysis with the Rasch analysis has shown that PARADISE 24 and the selection of 18 additional condition-specific items can be expected to have good measurement properties to assess the functional state in persons with dementia.

Effectiveness of Therapeutic Gardens for People with Dementia: A Systematic Review.

This paper is a systematic review of quantitative studies conducted on the benefits of visiting gardens and gardening therapy for people with dementia (PWD) in an effort to assess the effectiveness of such treatments and obtain information on the most appropriate garden design for this population. This review followed the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA) guidelines. Four databases were searched (PubMed, Web of Science, PsycINFO, Scopus), with no time limits. Out of a total of 480 articles considered, 16 studies were selected for review. In all but two of the studies examined, gardening therapy and the use of therapeutic gardens induced psychophysiological improvements in PWD. The areas showing the greatest effects were Engagement, Agitation, Depression/Mood, Stress, and Medication. It also emerged that interest in this sphere has been growing in the last decade, but there is still a shortage of empirical evidence of the beneficial effects of therapeutic gardens in relation to the type and severity of dementia, and of garden design guidelines. Despite the limited number of studies investigated, the review confirmed the benefits of gardening and therapeutic gardens in PWD. There is nonetheless a need to conduct more quantitative research to support currently-available evidence and generate more information, focusing on garden design criteria, in-garden activities, the type and severity of dementia examined, and effects on caregivers as well as on PWD.

[Psychological problems and cognitive impairments in the GUCH Community]. / Problematiche psicologiche ed alterazioni cognitive nella GUCH Community.

The increase of the GUCH Community requires a new definition of cardiac surgical success, which has to be considered either in terms of survival or quality of life and quality of health. Clinical and psychological problems are present in this population secondary to native cardiac disease, surgical correction, and social environment. Cognitive impairment after cardiac surgery is not rare, but an exhaustive evaluation of the psychological and neurodevelopmental outcome of patients operated on for total correction of congenital heart disease is complex and its clinical significance can be obtained by the integration of cardiological data, psychological status, and sociodemographic variables.
