When Clare Koo started becoming increasingly forgetful in the year leading up to her 50th birthday, her husband Patrick knew in his heart that something was not right.
It started with the mother of three misplacing her keys and slowly developed into Mrs Koo forgetting where she had parked her car.
A doctor suggested Mrs Koo might be experiencing menopause but a few years later she was diagnosed with early onset dementia.
“Because of what the doctor said, I thought I was not being sensitive to her,” Mr Koo said.
“It wasn’t good because early intervention could have made those early years more manageable.”
Mrs Koo, 57, took part in Alzheimer’s WA’s Walk to Remember at Perry Lakes Reserve yesterday to raise money to help those with dementia and raise awareness about the disorder.
Her husband joined her at the Perth event after taking part in the walks held in Mandurah and Albany last month.
Mr Koo said he was hopeful the events would raise awareness about the importance of getting an early diagnosis.
He said after noticing such a big change in his wife, her diagnosis came as a “melancholic relief”.
“At least I could educate and prepare myself,” Mr Koo said.
“It was extremely shocking for us because we both come from families with no such history.”
