The phenomenon of resilience as described by adults who have experienced mental illness

Abstract: Aim: This paper is a report of a study to explore the phenomenon of resilience in the lives of adult patients of mental health services who have experienced mental illness. ---------- Background: Mental illness is a major health concern worldwide, and the majority experiencing it will continue to battle with relapses throughout their lives. However, in many instances people go on to overcome their illness to lead productive and socially engaged lives. Contemporary mental health nursing practice primarily focuses on symptom reduction, and working with resilience has not generally been a consideration. ---------- Method: A descriptive phenomenological study was carried out in 2006. One participant was recruited through advertisements in community newspapers and newsletters and the others using the snowballing method. Information was gathered through in-depth individual interviews which were tape-recorded and subsequently transcribed. Colaizzi's original seven-step approach was used for data analysis, with the inclusion of two additional steps. ---------- Findings: The following themes were identified: Universality, Acceptance, Naming and knowing, Faith, Hope, Being the fool and Striking a balance, Having meaning and meaningful relationships, and 'Just doing it'. The conceptualization identified as encapsulating the themes was 'Viewing life from the ridge with eyes wide open', which involved knowing the risks and dangers ahead and making a decision for life amid ever-present hardships. ---------- Conclusion: Knowledge about resilience should be included in the theoretical and practical education of nursing students and experienced nurses. Early intervention, based on resilience factors identified through screening processes, is needed for people with mental illness.

Sprouting of dopamine terminals and altered dopamine release and uptake in Parkinsonian dyskinaesia

Abstract: Failed storage capacity, leading to pulsatile delivery of dopamine (DA) in the striatum, is used to explain the emergence of ‘wearing off’ and dyskinaesia in Parkinson’s disease. In this study, we show that surviving DA neurons in 6 -OHDA lesioned rats sprout to re-innervate the striatum, and maintain terminal density until »60% of neurons are lost. We demonstrate that DA terminal density correlates with baseline striatal DA concentration ([DA]). Electrochemical and synaptosome studies in 6 -OHDA lesioned rats and primates suggest that impaired striatal DA re-uptake and increased DA release from medial forebrain bundle fibres contribute to maintaining striatal DA levels. In lesioned rats where terminal density fell by 60% or more, L-DOPA administration increased striatal DA levels markedly.The striatal [DA] produced by L-DOPA directly correlated with the extent of dyskinaesia, suggesting that dyskinaesia was related to high striatal [DA]. While sprouting and decreased dopamine uptake transporter function would be expected to contribute to the marked increase in L-DOPA induced [DA], the increased [DA] was most marked when DAergic fibres were `60% denervated, suggesting that other release sites, such as serotonergic fibres might be contributing. In conclusion, the extent of dyskinaesia was directly proportional to the extent of DA terminal denervation and levels of extra-synaptic striatal DA. We propose that sprouting of DA terminals and decreased dopamine uptake transporter function prevent the appearance of Parkinsonian symptoms until about 60% loss of nigral neurons, but also contribute to dysregulated striatal DA release that is responsible for the emergence of dyskinaesia and ‘wearing off’.

Empathy and nonattachment independently predict peer nominations of prosocial behavior of adolescents.

Abstract: There is a plethora of research showing that empathy promotes prosocial behavior among young people. We examined a relatively new construct in the mindfulness literature, nonattachment, defined as a flexible way of relating to one's experiences without clinging to or suppressing them. We tested whether nonattachment could predict prosociality above and beyond empathy. Nonattachment implies high cognitive flexibility and sufficient mental resources to step out of excessive self-cherishing to be there for others in need. Multilevel Poisson models using a sample of 15-year olds (N = 1831) showed that empathy and nonattachment independently predicted prosocial behaviors of helpfulness and kindness, as judged by same-sex and opposite-sex peers, except for when boys nominated girls. The effects of nonattachment remained substantial in more conservative models including self-esteem and peer nominations of liking.
