Alexa For Dementia

Alexa for dementia. Dementia refers to a disease that impairs human cognitive functions, including thinking, communication, and memory. It is a degenerative disease that interferes with the daily lives of individuals and imparts various elements of it, such as the ability to focus, talk, or even see.

Alzheimer’s disease is the most familiar and common form of dementia along with vascular dementia, which occurs after a stroke. Previously, dementia was a disease that was associated with ageing; however, this has recently been changing. Changes in the biology of humans, as well as their lifestyles, has resulted in an increase in the occurrence of dementia.  The number of people suffering from dementia is estimated to be at a population of 47.5 million, a number that keeps growing as people under the age of 65 are also being affected by the disease.

Because the disease usually impairs the quality of life for individuals, it demands that the individuals directly or indirectly affected by the disease are given the necessary emotional support and specialized practical skills by trained nurses.

With the need for support amongst dementia patients growing, one would expect a paradigm shift in terms of digital interventions to offer support, but very few have been forthcoming thus far. However there have been a few technological advances such as with the invention of “Alexa” a virtual assistant developed by Amazon that is capable of numerous activities such as voice interactions, preparing to do lists, streaming podcast and music, playing audio books, and providing information such as weather, traffic and news in real time.

A lot of people typically always have an existing system that helps them with their tasks which is why Alexa’s design makes it possible for it to be used by dementia patients as it can be used as a home automation system and its capabilities extended through the installation of a third-party app known as skills. Below are some devices that have low interaction cost and feature Alexa that can help with Dementia patients. For those who are looking for a bit more than just the traditional Dementia Clock, why not check out the devices below.


Amazon Echo – 2nd Gen

The Amazon echo 2nd Gen is a voice-activated smart speaker that has Alexa incorporated to its functionality and acts as the user’s assistant.  The speaker utilizes Dolby processing, beamforming, and noise cancellation technology alongside seven microphones to ensure to deliver crisp vocals with deep bass and clear highs. With the Amazon Echo 2nd Gen, users can be heard from any direction even when music is playing, and the sound produced is 360-degree omnidirectional audio that is immersive in whatever room it is playing.

Benefits of Alexa for Dementia Patients

Dementia usually occurs in stages, and each stage affects patients differently. The use of Alexa for dementia patients, caregivers, and their support system is a new and innovative way to leverage technology towards assistive care for individuals in the early to mid-stages of dementia. Thus far there have been several benefits witnessed including;

  • Most of the devices incorporating Alexa are hands-free. Since the disease affects a patient’s dexterity, the handsfree feature is great as there is no touch or typing necessary should the patient need to use the device to for example call for help or order for food.
  • Alexa does not get frustrated. Because of the disease’s nature, patients may often require to repetitively ask the same question. Unlike humans, Alexa does not get frustrated or emit signs of frustration through this phase, which means patients can ask the same thing over and over for as long as they feel like.
  • There is the possibility of recording conversations between a patient and Alexa, which can be used to deduce useful inferences from the noticeable changes occurring in the patient’s routine/ life. From these inferences, a caregiver can find ways in which they can improve the patient’s life/ meet their needs.
  • Alexa can be used for relaxation purposes. Dementia patients, caregivers, and support system often experience anxiety, stress, and are easily frustrated; Alexa can play music or sound that is soothing and likely to induce relaxation. This goes a long way in improving the wellbeing of dementia sufferers.
  • With Alexa, it is possible to set reminders and alarms that are necessary for patients for example if they need to take their medication or schedule a doctor’s visit or any other activity that they need to remember. It is also possible to integrate a patient’s/ caregivers Google calendar so Alexa has access to it and can give reminders on important events.



Alexa has made it possible for patients with dementia, as well as their caregivers to be able to function efficiently and effectively. One of our favourite things about most of the Alexa incorporated devices is that they include a history section which allows caregivers to track patients queries to Alexa and as such monitor their wellbeing. While more strides need to be made to improve the functionality of digital devices to aid dementia patients, Alexa is a step in the right direction.
