Dementia is a large and growing problem worldwide. However, we still know relatively little about the language features of different types of dementia. This study aims to examine these features with a view to improving the diagnosis, assessment and treatment of clients with dementia. The focus of the study will be individuals with the following conditions. You do not need to have cognitive impairment or dementia to participate in this study:

  • Parkinson’s disease
  • Lewy body disease
  • Fronto-temporal dementia
  • Huntington’s disease
  • Multiple sclerosis
  • Motor neurone disease
  • Corticobasal degeneration
  • Progressive supranuclear palsy

Participants will be visited in their own homes or at another convenient venue by the principal investigator. Audio-recordings will be made as they engage in conversation and perform simple tasks such as picture description. Recording will last approximately 1.5 hours. All responses and patient data (age, diagnosis, etc.) will be treated in the strictest of confidence. The study has been given full ethical clearance by The Hong Kong Polytechnic University. Details are available on request.

In order to take part in the study, participants must be able to satisfy the following criteria:

  • Participants can be any age (above 18 years) and male or female
  • Participants must be native speakers of English
  • Participants must have functional vision and hearing (glasses/hearing aids can be worn)
  • Participants must have intelligible speech (mild speech impairment is not a problem)
  • Participants must have no previous neurological disorders (e.g. stroke)
  • Participants must have no previous developmental or acquired language disorder
  • Participants must be able to give informed consent
  • Participants must be willing for anonymized data to be used in publications
  • Participants must have a diagnosis of one of the above conditions confirmed by a medical specialist

If you are willing to participate in this investigation, I would really like to hear from. I can be contacted at the following email address: This email address is being protected from spambots. You need JavaScript enabled to view it.
