Background

Huntington's disease (HD) is a neurodegenerative disease characterized by a triad of motor, cognitive and psychological symptoms, leading to a gradual breakdown of communication skills. Few studies have investigated how people affected by HD and their professional caregivers, for example, medical doctors, physiotherapists and nurses, experience the patients’ gradual loss of speech and language.

Aims

To examine communication‐related experiences of patients and professional caregivers. Experiences with speech therapy and the use of augmentative and alternative communication aids (AAC) were also investigated.

Methods & Procedures

Seven individuals with HD and seven professional caregivers were interviewed individually, using a semi‐structured interview guide. Transcripts were analysed using a conventional content analysis, and the results presented in three main categories.

Outcomes & Results

Most individuals with HD were aware of having communication difficulties, struggling with understanding others as well as being understood. This was confirmed by professional caregivers, who also raised ethical issues encountered when patients struggled with communication. Both groups talked about external factors (such as noise or crowded social settings) as disrupting communication, and shared recommendations on how people in general, and speech and language therapists (SLTs) in particular, could optimize communication. Very few patients had received information about communication aids, and none was using AACs. Professional caregivers underlined the importance of interdisciplinary collaborations, including SLTs, in order to optimize care.

Conclusions & Implications

Findings shed a light on everyday communication challenges faced by people with HD and their professional caregivers, and the lack of implementation of communication aids in this group. The dramatic impact of HD on patients’ communication skills underscores the need to include SLTs in the follow‐up of this patient group, ideally from the early stages of the disease, while the patient is still capable of voicing his/her own wishes and thoughts. Future research that explores how to optimize communication and implement the use of AACs for individuals with HD is needed.

What this paper adds

What is already known on this subject

Although the ability to communicate gradually deteriorates in individuals affected by Huntington's disease (HD), there is little knowledge about how affected individuals experience the loss of speech and language skills. Interdisciplinary care is recognised as essential for this patient group. However, professional caregivers' thoughts and experiences of communicating with their patients have not been fully explored. Recent years have seen a rapid growth of available communication supporting technologies that could potentially be helpful for individuals with HD, but limited attention has been given to this subject.

What this paper adds to existing knowledge

What do we now know as a result of this study that we did not know before the results highlight that patients are aware of problems with speech and language even in early phases of the disease, and include patients' personal outlook on problems with communication. Professional caregivers raised ethical issues encountered when patients struggled with communication. Both groups described specific strategies that could facilitate communication. There was a significant lack of experience and knowledge about augmentative and alternative communication aids (AACs).

What are the potential or actual clinical implications of this work?

Clinical implications of this study. The introduction of communication aids in the follow‐up of patients with HD needs to be discussed with the patients in the early phases of the disease, and implemented while the individual still has the capacity to learn and take advantage of alternative communication support. Results underline the importance of including speech and language therapists (SLTs) into multidisciplinary care of patients with HD. SLTs should be available also for professional caregivers who need advice on how to facilitate conversations and social interactions, in order to optimise care of patients with HD.
