Memory aids for dementia

Our guide to the best assistive technology memory gadgets to help people with dementia, Alzheimer's or memory loss to stay safe at home.

Whether you're suffering from dementia or general memory problems, there are a range of gadgets available that could make a real difference to your life. From gadgets that prompt you to turn off the taps when running a bath to those that can help if you get lost when you're away from home, there are a wealth of products on offer.

While memory loss is a key element of Alzheimer's and other forms of dementia, forgetfulness can also be a part of the normal ageing process or a result of other diseases, such as depression or an underactive thyroid. If memory loss is a big worry for you, do consult your doctor who can assess its severity.

To help uncover the best memory aids, we asked a panel of assistive-technology experts to choose and review a range of memory aids - you can read their verdicts on each one in the table below. These include memory aids to stop your bath overflowing, medication reminders and pill dispensers, devices to help you monitor a relative who doesn't live with you and gadgets to stop you getting lost.
