I'm running the Belfast Marathon this May in memory of my granny Lilian, who passed away aged 81 last summer at the end of a long struggle with vascular dementia.

After seeing the progression of her illness and the effects it had on my family, I hope Alzheimer's Society and the research they fund will one day help develop new treatments for better improving the quality of life of other dementia sufferers.

I miss her every day and I'll remember her always.
