The Royal District Nursing Service has some excellent resources about Dementia and Diabetes available at no cost on their website.
Getting To Know Me - A Dementia Training Package is an online self-directed course that you can undertake at your own pace. It's been "designed to enhance the knowledge of clinicians working with people who have dementia." No special background knowledge or understanding of dementia is required.
There are six sessions altogether, which incorporate slides and videos as well as subject matter to read. You can view the sessions one by one or collectively. The length of time to complete the course will vary depending on past experience and the pace at which each person need to absorb the information.
There are also talking books available in languages other than English about diabetes (Greek, Italian, Macedonian & Vietnamese) and dementia (Vietnamese).
These books open in your internet browser like a book, with navigation arrows to turn the pages. The English version is written on the left hand page, the translated version on the right. To listen to the 'talking book', you click on the photograph of the translator, to the bottom right of the page. Clicking on the red box next to that photo will stop the audio. The books are also printable if you wish to have a hard copy available as well.
