About the study

TIHM (or TIM) for dementia is an NHS research study available in Surrey and North east Hampshire. It focuses on Internet of Things (IoT). The key aims are to support people with dementia and their carers.


This major NHS study, called TIHM (Technology Integrated Health Management) for dementia, aims to transform support for people with dementia and their carers.

The study's key aims are:

  • to improve the lives of people with dementia by supporting them to stay safe and well in their own homes
  • to reduce hospital and care home admissions
  • to relieve the stress on carers.

TIHM for dementia is for people with mild to moderate dementia who live at home in Surrey or North East Hampshire and who have a regular carer who is also willing to be involved.

Smart devices which are connected via an Internet of Things (the idea of connecting any device to the internet and/or each other) are installed in a person's home. These devices allow clinicians to remotely monitor a person's health, well-being and environment round the clock and in real time. If the technology identifies a health or safety problem, clinicians are immediately notified and can step in to offer support. For example, calling the person's carer to alert them to a potential problem or, arranging for an Alzheimer's Society Dementia Navigator to visit. If the technology identifies a crisis, the emergency services will be contacted.

Most of the devices operate in the background, collecting information. For example, sensors can measure a person's movements round the home and identify if they have had a fall. Some devices, such as a GPS tracker, can be worn and will alert clinicians if a person has wandered too far from home. Others, such as weight and hydration scales and a blood pressure cuff, require a person to interact with the device. The devices are not difficult to use and both the person with dementia and the carer are shown how to use them.

TIHM for dementia is designed to work alongside the existing care a person receives and will not replace that support.

The study is run in partnership with the Alzheimer's Society, and is being funded by the Department for Health, NHS England and Innovate UK.
