Link between neurodevelopmental disorders and suicidal risk in children

Area of Science:

• Child and Adolescent Psychiatry
• Neurodevelopmental Disorders
• Public Health

Background:

• Suicide is a critical public health concern in children and adolescents.
• Limited research explores the link between suicidal risk and neurodevelopmental disorders in this age group.
• Psychopathological profiles of children with serious suicide attempts resemble those who die by suicide.

Purpose of the Study:

• To characterize the dimensional neurodevelopmental profile of hospitalized children and adolescents who made serious suicide attempts.
• To investigate the prevalence of neurodevelopmental disorders in this vulnerable population.

Main Methods:

• Observational, prospective, single-center study.
• Utilized questionnaires and dimensional neurodevelopmental scales (Autism-Tics, ADHD, Social Responsiveness Scale, Conners-3).
• Included 21 patients aged 9-15 years hospitalized for serious suicide attempts.

Main Results:

• 70% of subjects (n=14) had at least one neurodevelopmental disorder (autistic traits, ADHD, learning, or motor disorders).
• 65% of subjects (n=13) presented with at least one behavioral disorder (oppositional defiant disorder, conduct disorder).
• The frequency of neurodevelopmental disorder traits was higher than in the general population.

Conclusions:

• Dimensional assessment of neurodevelopmental symptoms is crucial for identifying at-risk children.
• Tailored interventions based on dimensional profiles can enhance suicide prevention strategies.
• Findings suggest a significant overlap between neurodevelopmental disorders and serious suicide attempts in children and adolescents.
