An irresistible urge to return home; homesickness: When away on a foreign exchange program in Germany, one of the students was afflicted with philopatridomania and flew back to his family within a month of his stay.

It is not uncommon for young students to have a case of philopatridomania, if it is the very fist time to be away from home and family.

A case of philopatridomania can also be a compulsion to return to one’s native land, as seen in prisoners of war.
