An elderly couple missing from their Balga home have been found in Northam where they used to live.
Nikolai Kosakow, 81, and his wife Lorina Kosakow, 78, left their home about 5pm yesterday.
The couple's son, Robert Kosakow, said he couple arrived at an old friend's house on Newcastle Road in Northam just after 10am.
Earlier today police said that the couple suffered several serious medical conditions.
“They may also be in a confused state of mind," the spokeswoman said.
An attendant at a Gull service station in Alexander Heights spoke to a man matching Mr Kosakow's description about 11pm last night.
Robert Kosakow said his father told the female attendant he was returning home from Northam - where the couple had previously lived.
"(The Gull attendant) said he seemed disorientated and was looking for directions to get back to Balga," Mr Kosakow said. "They lived in Northam for most of their lives. No one has seen them there."
Robert Kosakow, who last saw his parents about 4pm yesterday afternoon, said there was no indication they had packed or planned to go anywhere.
On top of suffering dementia, Lorina Kosakow is also a diabetic.
"She needs her insulin and will start feeling the effects around lunchtime," her son said.
The missing couple's granddaughter Tara said her grandparents had never been missing for such an extended period of time.
Mr Kosakow is described as about 170cm tall with short grey hair, grey-blue eyes and a slim build.
Mrs Kosakow is about 168cm tall with grey-blonde hair, blue eyes and a medium build.
The couple drove through Alexander Heights at 11.30pm last night but have not returned home.
Anyone with information is asked to call police on 131 444.
