Individuals with intellectual disabilities who have no evidence of organic brain damage or genetic disorders are diagnosed with

cultural–familial mental disability.

Explanation:

The cultural–familial mental disability occurs when children born in families where there is a mentally disabled parent or sibling and who are raised in socioeconomically disadvantaged background show signs of being mentally disabled more than those who are born in families without mentally disabled individuals , and who are raised in socioeconomically stable homes. These children are said to be affected by cultural familial symptoms. They start showing that they are mentally disabled because they have been affected by the environment from which they grew up.
