Behavioral problems and family distress in tuberous sclerosis complex

Area of Science:

• Neuroscience
• Genetics
• Pediatrics

Background:

• Tuberous Sclerosis Complex (TSC)-associated neuropsychiatric disorders (TAND) significantly impact patients and families.
• Preventive vigabatrin (VGB) treatment has shown promise in improving intellectual outcomes in TSC.
• Understanding the impact of VGB on behavioral problems and family distress is crucial for comprehensive TSC care.

Purpose of the Study:

• To investigate the severity of behavioral problems in children and adolescents with TSC.
• To assess the degree of family distress in households affected by TSC.
• To compare outcomes between TSC patients with and without a history of VGB treatment.

Main Methods:

• The study included 21 pediatric TSC patients from four hospitals, divided into VGB and no-VGB groups.
• Standardized assessments, including the TAND Checklist, Aberrant Behavior Checklist (ABC), Social Communication Questionnaire (SCQ), and Social Responsive Scale-2nd edition (SRS-2), were used.
• Patient data were analyzed to compare behavioral scores and family distress levels based on VGB treatment history and intellectual functioning.

Main Results:

• No significant differences in behavioral problem scores were found between the VGB and no-VGB groups.
• Behavioral problems were more pronounced in TSC patients with mild intellectual disability compared to those with normal intelligence.
• Family distress, assessed via the TAND Checklist, correlated with social responsiveness scores (SRS-2) but not with IQ/DQ or seizure frequency.

Conclusions:

• Vigabatrin treatment does not appear to alter behavioral difficulties or family distress in TSC patients post-seizure onset.
• Social communication deficits represent a significant source of TAND impact on families.
• Comprehensive management strategies for TAND should address behavioral and social communication challenges in TSC.
