origin of cognitive prosthetics and evolution as a concept for dementia
A cognitive prosthetic is assistive technology that helps a person with cognitive deficits function more independently in certain tasks. It is an entire system that helps the individual in ways that are specific to that person’s needs. Below are features that define a cognitive prosthetic:
- A cognitive prosthetic is a compensatory strategy that directly assists the individual in performing daily activities. It helps a person to maximize their strengths and abilities to compensate for their deficits.
- A cognitive prosthetic is computer-based, meaning the system uses a desktop or laptop computer.
- The cognitive prosthetic is set up in the home or office
- A cognitive prosthetic is always developed and implemented through a therapeutic process that includes the therapist, the client, and computer programmers.
- A cognitive prosthetic is custom-designed for each individual client. This enables:
- Specific adaptation to the individual, the activities and the environment
- Faster acquisition of skills. Client’s are always able to start using the system from the first day of therapy.
- While it is being used by the client, a cognitive prosthetic captures data about how and when it is being used. This data is very helpful to the therapist to further customize the system to meet the client’s needs
Cognitive Prosthetics aim to aid both the carer and the client, providing both with the tools to aid the client’s memory, perform day to day tasks and enforce the aspect of dignity and security during the early stages of diagnosed dementia. ICP (Institute for Cognitive Prosthetics), founded and pioneered by Dr Elliot Cole based in Pennsylvania, have been using IT systems, in conjunction with social services to help neural rehabilitation.
Early micro-systems provided insight to whether brain-damaged clients could form sentences by interacting with a series of icons on computers. They also have been providing telerahabilition services since 1991, in conjunction with out-patient services. Furthermore early cognitive prosthetics have allowed the carer to connect to the client’s computer, providing the carer with a detailed knowledge of the client’s use of technology.
The key issues addressed with early cognitive prosthetics was utilising technology to enable the client to communicate with care professionals. It was recognised that top of the range healthcare was simply unavailable for much of the population who needed access to brain-trauma services. Cognitive Prosthetics aimed to provide in-home support for those individuals who could not travel to receive care, whilst also seeing a regular carer to aid their development at home.
Research has shown that memory-loss, security and dignity are serious issues for patients. Previous providers of care for dementia patient include Fold Telecare who provided users with warning systems, alarms and telephone support and are the main providers of in-home care products for sufferers of dementia in Northern Ireland today. Other cognitive prosthetics research such as those in Sweden (development of an easyADL prosthesis) have involved the use of VR to encourage clients to learn everyday tasks in order to be able to repeat them:

COGKNOW specialise in researching and delivering solutions for carers and sufferers of dementia specifically. Previous cognitive prostheitcs have focussed on providing cognitive resotration functionality for those with severe head injuries and brain trauma. The COGKNOW system goes beyond video-conferencing providing in-home support with interactive features and is available 24/7, something which telerehabilitation cannot provide.
The COGKNOW software system in development at the moment is easily manipulated and will be easy to install in the home. The technology is easily set-up in the home and provides useful reminders and easy to use telecommunication as well as providing enjoyable daily activities such as listening to the radio or phoning relatives or carers. COGKNOW and other cognitive prosthetic Research and Development are geared towards affording dementia sufferers a sense of security and re-assurance, whilst emphasising the need for those suffering from dementia to have a sense of self-reliance and confidence in the home.
Whereas competitors such as Fold Telecare have many instruments within the home to assist dementia; COGKNOW’s simple PDA and monitor with broadband access can provide these services, and is comparatively better value.
