The kids - matured somewhere around 5 and 18 - did not talk English, French or any nearby dialects, says Christopher Fomunyoh, a chief for the US-based National Democratic Institute (NDI).
Nigeria-based Boko Haram aggressors have augmented their fight into Cameroon.
The aggressors are battling to build an Islamic caliphate in north-eastern Nigeria.
They control a few towns and towns in the district and as of late promised devotion to Islamic State (IS) activists, who have seized huge regions of Syria and Iraq.
The kids were protected in Cameroon after security strengths - following up on a tip-off - assaulted what was thought to have been a Koranic school.
Mr Fomunyoh told the BBC's Randy Joe Sa'ah in Yaounde that he had gone to a shelter that was helping restore the kids.
He said the kids had spent so much time with their captors, being taught in jihadist philosophy, that they had forgotten about who they were.
"They've put some distance between their guardians," he said. "They've put some distance between individuals in their towns, they're not ready to lucid, to help follow their connections, they can't even let you know what their names are."
In the mean time, a suspected Boko Haram assault on Tuesday killed no less than six individuals at a commercial center in the northern Nigerian town of Maiduguri.
The suicide bombarding was supposedly done by a moderately aged lady.
