Welsh actress Ruth Jones is fronting Alzheimer's Society Dementia Awareness Week.
Her mother-in-law Margaret had dementia and she describes her family's experiences in a film made with ITV's Daybreak.
Ruth says: "noticing the gradual decline in her memory and her ability to deal with the day-to-day, that was the most upsetting thing."
"Talking changes everything - it makes the problem less scary - and we all can club together to deal with it."
