Brain stimulation study seeks people with Alzheimer’s or mild cognitive impairment
People living with Alzheimer’s are helping researchers to test a brain stimulation technique that could lead to future treatments.
Even the most exciting technological developments need the participation of people with lived experience if they’re to succeed in the real world.
Nir Grossman, a researcher at the UK Dementia Research Institute, is pushing the bounds of what’s possible in treating the diseases that cause dementia. Yet he underlines how the impact of his team’s work depends on insights they gain from people living with dementia.
‘As well as people participating in the study, we’ve also had workshops to hear from patients, carers and families,’ he says.
Non-invasive headset in development
Nir’s team is developing a headset that can stimulate areas deep within the brain without using anything invasive, such as surgical implants.
We need to know – if we’re going to succeed in this – what people’s concerns are, what their expectations are. Their input has been very, very helpful for us.
The prize-winning innovation behind Nir’s research is called temporal interference (TI) brain stimulation. This uses harmless electric fields, precisely targeted to affect what cells in specific parts of the brain are doing.
‘The particular structure in the brain we are interested in is called the hippocampus,’ says Nir. ‘This area is pivotal for the operation of our memory and other functions.’

Researcher Nir and volunteer Nigel.
Having already proved the technique is safe to use, Nir’s team is testing TI in people with either mild cognitive impairment or early stage Alzheimer’s.
Memory loss is a common initial symptom of Alzheimer’s because the disease usually affects the hippocampus and connected areas first. The idea is to use TI to regulate the activity of brain cells in ways that help them to function well for longer.
The study is seeing how TI could help people’s dementia symptoms – reducing how much it affects their memory and thinking. However, in the longer term, Nir hopes it could eventually offer more than this.
Our vision is to create a disease-modifying intervention that not just improves the symptoms, but really changes the course of the disease.
Opportunity to take part in research
Nigel Whiteley heard about the opportunity to take part in Nir’s study through Join Dementia Research. Through this programme, you can register to hear about studies that are looking for people like you.
‘Research work was something I myself had done in a London hospital decades ago,’ says Nigel, who now has Alzheimer’s. ‘I know the importance of research.
‘I soon realised that I was just the right type of person these researchers were looking for.’
Taking part involves Nigel doing memory and thinking tests while his brain cells are stimulated.
It’s interesting to learn a bit about what the researchers can see on a screen, which indicates to them what is going on in a part of my brain as I carry out various tests.
No reservations about volunteering
Although it takes time and concentration – and occasionally feels repetitive – Nigel understands that it’s the only way to make progress.
‘Having done research work myself, I know that it is essential to repeat a test in the same way as before, except for changing just one thing each time.’
Nir’s study is looking for more participants, and Nigel has no reservations about encouraging others to see how they could help.
‘If you can set aside the time to be a “guinea pig” in research work on Alzheimer’s disease, then do volunteer.
How else can we find a potential cure, unless we volunteer to give our time and efforts for research?
