Abstract
This review aimed at exploring the psychosocial disorders of Nigeria as a nation, its effect on the citizens
and the remedy. Psychosocial disorder is a mental illness induced by life experiences, stress, as well as
maladaptive cognitive and behavioural processes. The prevalence of these disorders include depression,
schizophrenia, anxiety disorders, substance use disorder, personality disorder and autism spectrum
disorders have rapidly increase over the past years in Nigeria with its negative impact on the socioeconomic
status, psychological well-being; peaceful coexistence and mental health of the entire society. These have
precipitated some social anomalies such as bribery and corruption, antisocial behaviour, religious
fanaticism, terrorism and so on. The study therefore recommends the need for government to implement
effective mental health interventions program that would facilitate easy access to mental healthcare services
in Nigeria. There is also an urgent need to improve the mental health awareness of Nigerians through
education and public mental health campaign.
