He said the organisation also helped to keep his mother-in-law as independent as possible when she was first diagnosed, although she was now in a rest home.
"I think it is one of those things, until you do get affected, you don't think about it.
Mr Wilson said it was made a bit easier by the help of the organisation.
"They were certainly very helpful and they still phone up now and again to see how she is going."
He said while he was no expert on the illness, the biggest piece of advice he held on to was not getting frustrated with having the same conversations over and over.
Alzheimer's Rotorua office manager and community liaison Elaine Fox said it was great to see about 60 people turn up for the walk.
It is the first time the local branch has run one and Mrs Fox said the main aim was to raise awareness and de stigmatise dementia.
Mrs Fox said locally they supported about 300 people with dementia, and their families and carers.
"For every one person with dementia there are at least two carers or family members affected as well."
