A veterinary case describes worsening structural epilepsy despite a multi-drug regimen, not a controlled test of one benzodiazepine.
What the source reports
A cat with longstanding cortical abnormalities received phenobarbital, zonisamide, diazepam, and gabapentin. Seizures that had been partly controlled became more frequent with age. Advanced imaging and intracranial video-EEG were used to plan surgery targeting the suspected epileptogenic region.
Limits and uncertainty
The single case cannot determine whether worsening reflected tolerance to diazepam, progression, dosing limitations, or other factors. Several medicines were changed or maintained over time. Surgical results also cannot be assigned to one preoperative medication.
Implications for forensic review
For veterinary forensic review, distinguish structural disease and longitudinal treatment failure from a claim about benzodiazepine tolerance. Reconstruct the seizure history, dose changes, adherence, and localization evidence. The report illustrates a complex diagnostic and treatment pathway rather than validating a general conclusion about diazepam effectiveness.
