ADHD-like behavior in a patient with hypothalamic hamartoma.

Area of Science:

• Neuroendocrinology
• Pediatric Neurology
• Behavioral Science

Background:

• Hypothalamic hamartoma (HH) is a rare congenital brain malformation.
• Central precocious puberty (CPP) can be associated with HH, leading to early pubertal development.
• Psychiatric comorbidities, including attention deficit hyperactivity disorder (ADHD), are increasingly recognized in association with HH.

Observation:

• A male patient with HH presented with CPP at age 4, treated with GnRH analogue.
• At age 9, the patient exhibited emotional instability, aggression, and ADHD-like symptoms without seizures.
• Discontinuation of GnRH analogue treatment led to observed sexual urges, which resolved upon reinitiation of treatment.

Findings:

• This case highlights behavioral problems in HH without seizures, a rare occurrence.
• The patient's ADHD-like symptoms improved with methylphenidate and GnRH analogue therapy.
• Hyperandrogenism may contribute to ADHD-like symptoms in patients with HH.

Implications:

• Combined GnRH analogue and methylphenidate therapy may be beneficial for managing behavioral issues in HH.
• Further research is needed to understand the link between HH, hyperandrogenism, and psychiatric comorbidities.
• This case underscores the importance of a multidisciplinary approach in managing complex pediatric neurological conditions.
