Neurological and intellectual disabilities among adolescents within a custodial institution in South-West Nigeria.

A total of 67 adolescents from a juvenile remand home were matched with 67 other adolescents by age and gender, with a view to determine the prevalence and spectrum of neurological and intellectual disabilities. Intelligence quotient (IQ) was estimated using an adapted version of the Slosson's Intelligence Test and a full neurological evaluation was carried out. The mean IQ score for the remand home participants was significantly lower than the controls (77 ± 11 vs. 99 ± 14; t = 1.6, P = 0.001). Almost half (46.7%) of the participants in the remand home had intellectual disability of varying degrees, including borderline intellectual functioning, compared with only two (3.3%) of the comparison group (P < 0.001). Epilepsy and neurological deficits were significantly more prevalent among the remand home group, particularly those admitted as victims of neglect, compared with the comparison group (P ≤ 0.02). These findings and recent literature were used to speculate the possible underlying factors. Policy implications for child social welfare in Nigeria were suggested.
