"My mother having dementia turned into a chance for us to relate to each other again and even have fun in each other's company."

That's what film director Yuka Sekiguchi came to realize when she returned to Japan in 2009, after 29 years in Australia, to look after her 78-year-old mother, who was then in the early stages of Alzheimer's disease.

She took the opportunity to film her mother on a daily basis as the disease progressed — in the home, at the doctor's office, on the street and in parks.
