Anne was 70 years old at the time of her death.
Throughout the BBC series, Ms Duffy had spoken movingly about her mother's health battles and her determination to win prize money so they could spend precious time together.
Anne received her Parkinson's diagnosis at 47, only four years older than Duffy is now, and later developed dementia.
During her time in the castle, Ms Duffy opened up to cameras about her mother's condition, explaining that despite facing these challenging illnesses, Anne continued to amaze her family daily.

Ms Duffy lost her father in 2016 when he was 67.
Entering the castle, Ms Duffy hoped to be selected as a Traitor, a wish that was granted alongside barrister Hugo Lodge and Scottish cyber security consultant Mr Libby.

On Friday, she and Mr Libby made television history by becoming the first duo of Traitors to successfully win together in the show's fourth series.
Their victory came after they eliminated every remaining Faithful during the tense finale. The pair divided the £95,750 prize pot equally, taking home £47,875 each.
Following her win, Ms Duffy told BBC News NI that treating her mother would be her first priority with the prize money.
