The Nigerian tertiary education system admits mostly teenagers and young adults from different ethno-religious and family backgrounds, some of whom may have inherent risks and predisposition to mental illness. They then undergo stressful conditions related to the university life such as long durations of lectures, over-crowding, and lack of social amenities, haphazard lecture schedules as well as incessant industrial strike actions of academic and non- academic staff. In spite of these, there appears to be few studies on the burden of emotional and mental disorders among Nigerian University students, and none was cited suggesting interventions that may be appropriate.
