  • Research summary

    The aim of this study is to understand whether patients with either memory complaints, suspected movement disorders, such as Parkinson’s disease, people who have suffered a Stroke and healthy volunteers can talk to computerised doctor (CognoSpeak) regarding their neurological health. CognoSpeak is a computerised person i.e. human looking computer generated image that will ask the participant questions regarding their health. In this study CognoSpeak will not be able to respond to the participant answers but the answers can be analysed by a person or a computer to look for features of speech and interaction seen in dementia or other memory disorders. This study will also collect healthy people to speak to CognoSpeak, so that the study team can compare the patient data to a group of participants with no cognitive complaints.

    The study will look into how people with memory problems talk about their experiences and difficulties they may have in daily life because of their memory problems.

    At present it often takes a long time before memory problems are diagnosed accurately. The results of this study could feed into future clinical trials of efficacy, tolerability and feasibility of utilising CognoSpeak as a cognitive diagnostic aid. This in turn could allow doctors to diagnose the causes of memory problems more accurately and more quickly by using this computer system to ask questions and record answers about their memory problems.

    In an earlier study, the study team have shown that examining how people with memory complaints can help distinguish dementia from other types of memory problems such as those due to excessive worry. This study is to further develop CognoSpeak to measure mood and cognition over a long period of time and in different patient groups.
