Visibly black people of African and African-Caribbean descent (black people) are 2-5 times more likely to be diagnosed with schizophrenia and other psychoses than their counterparts from other ethnic minorities in the United Kingdom. However, the symptomology of psychotic illnesses and dissociative experiences are difficult to differentiate. Interestingly, black people detained under the Mental Health Act are more likely to give perceived racism as the cause of their emotional distress than their counterparts from other ethnic groups, but there is very little indication in the literature as to how perceived racism might exert its effect on black people's mental health.
