"We often get a lot of people contacting us in the new year, as people have picked up the signs and symptoms that a loved one may have dementia over the Christmas, family reunion period," says Dementia New Zealand chief executive Paul Sullivan.
Anita said Richard started to become a little introverted soon after his diagnosis.
"He is a fairly social man and loves a chat but was afraid of what he was going to say to people and of repeating himself."
But after five years, Richard is more positive, saying he is "here for a good time not a long time".
Sullivan said it was important to know the signs of dementia, but to also know what not to look for.
"Repeating a story to your spouse because you forgot you had already shared it is a normal part of any relationship, but if your husband repeats the same story 10 times in a day, taking him to see your GP is in order.
"Forgetfulness is a normal part of life, but memory loss isn't."
The early signs of dementia to look out for are poor short-term memory, inability to carry out common tasks, such as preparing a meal, personality changes, struggling to follow conversations, becoming depressed or withdrawn, difficulty with abstract thinking, poor judgment and disorientation with time and place.
