Assessment of patient and caregiver needs in fragile X-associated tremor/ataxia syndrome by utilizing Q-sort methodology

Like an extended family: Relationships that emerge when older caregivers use written messages to communicate in an ICT-based healthcare service

OBJECTIVE

To explore the relationships that emerge amongst caregivers of persons with dementia and stroke when caregivers use written messages as their communication tool in a closed information and communication technology (ICT)-based support group.

METHODS

An explorative design with a qualitative approach was used that applied systematic text condensation (STC) to analyse 173 written messages extracted from a web forum.

RESULTS

Empathetic, empowering and familiar relationships emerged amongst peers of older caregivers when the caregivers used written messages as their communication tool. The empathetic relationship was characterised by sincerity and openness when the caregivers shared emotions related to caregiving. The empowering relationship reflected a fellowship based on solidarity influenced by a sense of optimism and a willingness to share knowledge to support one another in overcoming challenges. In the familiar relationship, the caregivers were thoughtful and good-humoured with one another and displayed an attitude of consideration towards one another, as in an extended family.

PRACTICE IMPLICATION

The use of computer-mediated communication in health care service will change the context of establishing and maintaining interpersonal relationships. Therefore, greater knowledge regarding how the peers of caregivers interact with one another is vital so nurses may better support and educate ICT-based support groups.

Risk Factors for Cognitive Impairment in Fragile X-Associated Tremor/Ataxia Syndrome

Fragile X-associated tremor/ataxia syndrome (FXTAS) is a late-onset neurodegenerative disease with motor, psychiatric, and cognitive manifestations that occurs in carriers of the fragile X mental retardation 1 ( FMR1) gene premutations. This was a retrospective chart review of 196 individuals (127 men and 69 women) with FXTAS. Forty-six (23%) participants were cognitively impaired, of whom 19 (10%) had dementia. Risk factors for dementia were examined (CGG repeat size; alcohol, benzodiazepine, and opioid use; diabetes; hyperlipidemia; hypertension; hypothyroidism; obesity; sleep apnea; surgeries with general anesthesia; depression; family history of dementia). Thirteen individuals with FXTAS and dementia were then compared to 13 cognitively intact individuals matched on age, gender, and FXTAS stage. CGG repeat size was significantly higher (mean = 98.5, standard deviation [SD] = 22.2) in the dementia group, compared to the cognitively intact group (mean = 81.6, SD = 11.5; P = .0256). These results show that CGG repeat size is a risk factor for FXTAS dementia.

Understanding fragile X syndrome from a mother's perspective: Challenges and resilience

The purpose of this study is to communicate findings from a case study on a South African mother with three children diagnosed with full mutation fragile X syndrome (FXS). The participant is an unaffected carrier of FXS. Research has shown that mothers of children with FXS often experience high levels of parenting stress and low levels of psychological well-being. However, observations made have piqued curiosity about their positivity and determination to carry on each day raising children diagnosed with FXS. The aim is to develop a better understanding of the manner in which a mother of children with FXS make sense of her situation, to gain further insight into the specific resilience processes she acquired. A qualitative case study approach was followed, gathering data through semi-structured interviews based on open-ended questions. The findings offer new insights into a South African mother's life raising children with FXS. Even though there is very limited support and little awareness of FXS in South Africa, she still found ways to seek help, and find solutions to every day challenges. The study conclusions discourage blind stereotyping of mothers of children with FXS as vulnerable only. Future research should concentrate on promoting awareness, education, advocacy, and support for individuals with FXS in South Africa.

Constructions of sex and intimacy after cancer: Q methodology study of people with cancer, their partners, and health professionals

BACKGROUND

The increasing number of individuals living with cancer has led to a focus on the quality of life of survivors, and their families. Sexual wellbeing is a central component of quality of life, with a growing body of research demonstrating the association between cancer and changes to sexuality and intimacy. However, little is known about patient and professional understanding of cancer and sexuality post-cancer. This study was designed to explore the complex perspectives that people with personal and professional experience with cancer hold about sexuality in the context of cancer.

METHODS

An interview study using Q methodology was conducted with 44 people with cancer, 35 partners of a person with cancer and 37 health professionals working in oncology. Participants were asked to rank-order 56 statements about sexuality and intimacy after cancer and asked to comment on their rankings in a subsequent semi-structured interview. A by-person factor analysis was performed with factors extracted according to the centroid method with a varimax rotation.

RESULTS

A three-factor solution provided the best conceptual fit for the perspectives regarding intimacy and sexuality post-cancer. Factor 1, entitled "communication - dispelling myths about sex and intimacy" positions communication as central to the acceptance of a range of satisfying sexual and intimate practices post-cancer. Factor 2, "valuing sexuality across the cancer journey," centres on the theme of normalizing the experience of sex after cancer through the renegotiation of sex and intimacy: the development of alternative sexual practices. Factor 3, "intimacy beyond sex," presents the view that even though sex may not be wanted, desired, or even possible following cancer, quality of life and relationship satisfaction are achieved through communication and non-genital intimacy.

CONCLUSIONS

This study has demonstrated the complexity of perspectives about sexuality and intimacy post cancer, which has practical implications for those working in cancer care and survivorship. Therapists and other health professionals can play an important role in ameliorating concerns surrounding sexual wellbeing after cancer, by opening and facilitating discussion of sexuality and intimacy amongst couples affected by cancer, as well as providing information that normalizes a range of sexual and intimate practices.

Caregiver Burden in Fragile X Families

Complex caregiving issues occur in multigenerational families carrying the fragile X mutation and premutation. The same family members may care for children or siblings with fragile X syndrome (FXS) and for elderly parents with fragile X-associated tremor/ataxia syndrome (FXTAS). Family caregivers experience anxiety, depression, neglect of personal health care needs, employment difficulties, and loss of social support, leading to isolation and further psychiatric consequences. There is growing awareness of caregiver burden with regard to parents of children with FXS, but much less is known about the needs of informal caregivers of patients with FXTAS. In this paper, we review the available literature to date and provide suggestions for further exploration of caregivers' needs. Evidence-based strategies to address these needs are included. Many more research studies exploring caregiver burden in multigenerational fragile X families are needed, as well as studies aimed at investigating interventions and their impact on reduction.

Ages of Onset of Mood and Anxiety Disorders in Fragile X Premutation Carriers

OBJECTIVE

FMR1 premutation carriers of both genders have a high lifetime prevalence of anxiety and depressive disorders, however little is known regarding the onset ages of these conditions. This study compared onset ages of mood and anxiety disorders in premutation carriers with typical onset ages of the same disorders in the general population.

METHODS

Eighty-one premutation carriers (42% men; average age 62, SD 10) with and without FXTAS completed the Structured Clinical Interview for DSM-IV-TR. Onset ages of mood and anxiety disorders were compared to the corresponding typical population onset ages using the signed rank test.

RESULTS

Overall median onset ages of MDD (46 years old, p < 0.0001), panic disorder (40 years old, p = 0.0067), and specific phobia (11.5 years old, p = 0.0003) were significantly higher in premutation carriers compared to the general population. Median MDD onset ages in male carriers (52 years old) and those with FXTAS (49.5 years old) were significantly higher relative to the general population (median 32, both p < 0.0001). Tremor and ataxia emerged significantly later than MDD and the anxiety disorders studied.

CONCLUSION

Depressive and anxiety disorders in premutation carriers have a later onset compared to the general population, but precede the onset of motor symptoms. This may be due to progressive mRNA toxicity in the limbic system, white matter changes leading to neuronal dysconnectivity, and interaction with environmental factors. Psychosocial factors may be protective. Further research is needed to understand the full spectrum of psychiatric phenotypes in FMR1 premutation carriers.

COGNITIVE DYSFUNCTION IN FMR1 PREMUTATION CARRIERS

Premutation carriers of the fragile X mental retardation gene (especially men) older than 50 may develop a neurodegenerative disease, the fragile X-associated tremor/ataxia syndrome (FXTAS). Carriers may present with varied cognitive impairments. Attention, working memory, declarative and procedural learning, information processing speed, and recall are among the cognitive domains affected. Executive dysfunction is a prominent deficit, which has been demonstrated mostly in men with FXTAS. In more advanced stages of FXTAS, both men and women may develop a mixed cortical-subcortical dementia, manifested by psychomotor slowing and deficits in attention, retrieval, recall, visuospatial skills, occasional apraxia, as well as overt personality changes. Studies have shown dementia rates as high as 37-42% in older men with FXTAS, although more research is needed to understand the prevalence and risk factors of dementia in women with FXTAS. Neuropsychiatric symptoms are common and reflect the dysfunction of underlying frontal-subcortical neural circuits, along with components of the cerebellar cognitive affective syndrome. These include labile or depressed mood, anxiety, disinhibition, impulsivity, and (rarely) psychotic symptoms. In this paper we review the information available to date regarding the prevalence and clinical picture of FXTAS dementia. Differential diagnosis may be difficult, given overlapping motor and non-motor signs with several other neurodegenerative diseases. Anecdotal response to cholinesterase inhibitors and memantine has been reported, while symptomatic treatments can address the neuropsychiatric manifestations of FXTAS dementia.

Neuropathological, clinical and molecular pathology in female fragile X premutation carriers with and without FXTAS

Fragile X-associated tremor/ataxia syndrome (FXTAS) is an adult-onset neurodegenerative disorder associated with premutation alleles of the fragile X mental retardation 1 (FMR1) gene. Approximately 40% of older male premutation carriers, and a smaller proportion of females, are affected by FXTAS; due to the lower penetrance the characterization of the disorder in females is much less detailed. Core clinical features of FXTAS include intention tremor, cerebellar gait ataxia and frequently parkinsonism, autonomic dysfunction and cognitive deficits progressing to dementia in up to 50% of males. In this study, we report the clinical, molecular and neuropathological findings of eight female premutation carriers. Significantly, four of these women had dementia; of the four, three had FXTAS plus dementia. Post-mortem examination showed the presence of intranuclear inclusions in all eight cases, which included one asymptomatic premutation carrier who died from cancer. Among the four subjects with dementia, three had sufficient number of cortical amyloid plaques and neurofibrillary tangles to make Alzheimer's disease a highly likely cause of dementia and a fourth case had dementia with cortical Lewy bodies. Dementia appears to be more common than originally reported in females with FXTAS. Although further studies are required, our observation suggests that in a portion of FXTAS cases there is Alzheimer pathology and perhaps a synergistic effect on the progression of the disease may occur.
