Home and Away newcomer Jessica Redmayne opens up over mum's dementia diagnosis

 "It changed my perspective on the world."

"Dad said to me, everyone has their s**t, and this is ours. It changed my perspective on the world. To know they're going to inevitably forget who you are, and have no concept of me being her daughter is incredibly challenging," Redmayne said.

She continued: "She got to a point where she still knew my name, but didn't realise I was her child. She thought I was her best friend, she couldn't grasp she had kids."

Dementia is a neurological condition that causes a person's brain to lose its ability to think clearly and remember things and people, leading to confusion and an inability to carry out everyday tasks.

Redmayne is currently fronting Dementia Action Week in Australia, which raises awareness of the condition and runs from September 18 to 24.

Recently, ITV newsreader Alistair Stewart opened up about his own dementia diagnosis, explaining that he was diagnosed after he began to feel "a bit discombobulated."

"I wasn't becoming forgetful, but things like doing up your shoelaces properly – that's how I wear these lovely moccasins now – making sure your tie was straight, remembering that the call time for your programme is four o'clock and not five o'clock, not turning up early or late, and stuff like that," he said.

Meanwhile, Coronation Street's Julie Goodyear was diagnosed with dementia earlier this year while Bruce Willis' wife, Emma Heming Willis, spoke about her husband's condition last month.
