Major hyperekplexia in a child caused frequent falls triggered by stimuli. Treatment with clobazam and clonazepam effectively stopped falls and restored walking ability.
Area of Science:
- Neurology
- Pediatrics
- Genetics
Background:
- Hyperekplexia is a rare neurological disorder characterized by exaggerated startle responses.
- The major form of hyperekplexia can lead to significant motor impairment, including falls and developmental delays.
- Genetic mutations are often implicated in the pathophysiology of hyperekplexia.
Observation:
- A pediatric patient presented with the major form of hyperekplexia.
- The child experienced frequent, unexpected falls.
- These falls were consistently triggered by acoustic and visual stimuli, severely impacting ambulation.
Findings:
- A combination therapy of clobazam and clonazepam was administered.
- This pharmacological intervention was well-tolerated by the patient.
- The treatment resulted in a rapid and dramatic cessation of falls.
- Ambulation was successfully restored.
Implications:
- This case highlights the efficacy of clobazam and clonazepam in managing severe hyperekplexia.
- Early and effective treatment can significantly improve motor function and quality of life in affected children.
- Further research into the neurobiological mechanisms underlying stimulus-induced falls in hyperekplexia is warranted.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
