Aims: This study assesses the clinical profile of children and adolescents with psychotic disorders
presenting to a psychiatric facility in Lagos, Nigeria.
Study Design: The study design was a retrospective chart review.
Place and Duration of Study: The study was conducted at the largest child psychiatric facility in
Nigeria, the Child and Adolescent center of the Federal Neuro-Psychiatric Hospital, Yaba, Lagos,
from October to December 2011.
Methodology: Patients (n=168) with early onset psychotic disorder presenting to the facility within
a two year period (September 2009 to August 2011) were reviewed. Using a pro-forma containing
variables of interest derived from a literature review of the research subject, the case notes of all
children and adolescents with psychotic disorder presenting to the facility were reviewed to
determine their presentation, clinical characteristics and diagnostic subtypes. Diagnoses were
according to the ICD-10 criteria.
Results: Males (56.5%) out-numbered females and the mean age of the sample was 15.3 (±3.6)
years. The age at onset of psychotic disorder ranged from 6 to 18 years with a mean age of
14.2 (±2.6) years. Onset of psychosis was described as gradual/insidious by 47% and abrupt/acute
by 53%. About one out of five (20.8%) had history of birth complications while 19% had delayed
attainment of developmental milestones. Insomnia (49.4%), auditory hallucination (48.8%),
irrational speech (40.5%) and aggressive behavior (33.3%) were the most prevalent symptoms.
The most common axis I diagnoses was schizophrenia (36.9%), followed by organic psychosis
(25%) and acute psychotic disorder (19.6%).
Conclusion: Our findings indicate the need for early intervention in psychosis and planning of
services to meet the needs of young people with psychotic disorders in Nigeria. The relative
preponderance of obstetric complication and organic psychosis highlights an unmet need for
improved obstetric care with consequent reduction in psychosis
