Wandering is one of the unknown consequences of Alzheimer's disease.
Disoriented and losing their bearings, some patients are sometimes unable to reach their homes.
This is the case of Hisham's father, El Mekki Terrak, who has now passed away for five years.
"My father disappeared in the summer of 2015, we were in July. He was at a friend's house, and he wanted to go home. And that's when we heard no more", explains his son to France 24.
