If you're not experiencing it first-hand, it's difficult to understand the reality of living with dementia during COVID-19 - something Sean Cullen wanted to change. His mum has dementia. The difficult experience during lockdown motivated him to write a poem, titled 'Imagine'. He worked with Alzheimer's Society to bring the poem to life, in an emotive short film. 'Imagine' puts the viewers in the shoes of those affected by dementia during lockdown - to raise awareness of how tough it has been and to encourage people to donate to Alzheimer's Society's Emergency Appeal, to support others in need.
