iSupport is a self-help skills and training programme for carers of people with dementia. Worldwide, around 55 million people have dementia. Dementia causes significant psychological and emotional impact on families and carers. iSupport aims to prevent and/or decrease mental and physical health problems associated with caregiving and to improve the quality of life of those caring for people with dementia. iSupport was conceptualized and developed as an online training programme. However, in areas of the world with limited internet bandwidth or low digital literacy, the iSupport hardcopy manual can be printed and used offline. In five modules, iSupport teaches carers what dementia is and how to respond to common challenges of caregiving. The five modules are (i) introduction to dementia; (ii) being a caregiver; (iii) caring for me; (iv) providing everyday care; and (v) dealing with behaviour changes.
