It frequently manifests in patients with neurodegenerative disorders such as Parkinson’s disease (PD) and dementia. Using a qualitative approach, this study aims to explore the impact of hypersexuality on spousal carers of patients with PD and dementia.Design Qualitative study using semistructured interviews and thematic analysis.Setting This study was conducted in secondary care settings, including movement disorder and dementia clinics, as well as through patient support organisations. Participants were recruited from multiple centres across the UK. Interviews were conducted in a clinical research setting.Participants Eight spousal carers (five caring for patients with PD, three for patients with dementia) participated in the study. Participants were selected based on their role as primary carers and their experience managing hypersexuality in their partners.Results The thematic analysis identified 12 themes: manifestations, sexual practices, impact, control, emotional formulations, beliefs in causes of hypersexuality and attributions, relationship with the partner, dealing with hypersexuality, coping with hypersexuality, self-image, stigma and professional help-seeking. Hypersexuality altered patients’ sexual cognitions and behaviours, causing distress and strain on carers’ mental health and marital life. Carers struggled to cope with their partners’ hypersexuality, facing emotional burden and barriers to seeking professional help.Conclusions Hypersexuality significantly impacts spousal carers of patients with PD and dementia, affecting their emotional well-being and relationships. Healthcare professionals should recognise and address hypersexuality’s psychological and relational consequences. Psychoeducation, support groups and tailored interventions for patients and carers are recommended to alleviate emotional distress. Future research should explore the broader familial impact of hypersexuality and develop effective management strategies.Data are available upon reasonable request.
