Self-injurious behavior in acquired sensory neuropathy

Area of Science:

• Neurology
• Pediatrics
• Toxicology

Background:

• Self-abusive behavior is commonly associated with congenital sensory neuropathy.
• Acquired peripheral nerve dysfunction can also lead to self-injurious behaviors.
• Peripheral neuropathies can manifest with sensory disturbances like paresthesias.

Observation:

• Two children with acquired peripheral nerve dysfunction exhibited self-abusive behavior.
• One case involved self-trauma after median nerve injury; the other followed insecticide poisoning causing diffuse neuropathy.
• Both patients showed improvement in self-injurious behavior.

Findings:

• Improvement in self-mutilation appeared linked to anticonvulsant medication use.
• Anticonvulsants are sometimes used for paresthesias in peripheral neuropathy patients.
• This suggests anticonvulsants may be a viable treatment for self-abusive behavior in pediatric peripheral neuropathy.

Implications:

• Anticonvulsant medications may offer a therapeutic option for children with self-abusive behavior secondary to peripheral nerve dysfunction.
• Further clinical trials are warranted to confirm the efficacy of anticonvulsants in this patient population.
• Understanding the link between nerve dysfunction and self-injury can guide treatment strategies.
