Clinical Risk Factors for Early Seizure Recurrence in Dogs Hospitalized for Seizure Evaluation

Area of Science:

• Veterinary Neurology
• Canine Epilepsy Research
• Seizure Management

Background:

• Epileptic seizures are a frequent reason for canine neurological evaluations.
• Understanding seizure recurrence is crucial for effective patient management.

Purpose of the Study:

• To determine the timing, frequency, and risk factors for early seizure recurrence (ESR) in hospitalized dogs.
• To aid in rapid decision-making regarding intensive care unit (ICU) or day ward placement.

Main Methods:

• Retrospective study of 214 dogs with seizure evaluations between 2000 and 2017.
• Analysis of risk factors for ESR in dogs with idiopathic epilepsy (IE), structural epilepsy (StE), and reactive seizures (RS).

Main Results:

• 50% of dogs experienced ESR, with an average time to recurrence of 7 hours.
• Risk factors for ESR varied by epilepsy type, including abnormal neurological exams, seizure history (cluster seizures, status epilepticus) within 72 hours prior to admission.
• Abnormal neurological examination, cluster seizures, or status epilepticus within 72 hours predicted ESR in the overall cohort.

Conclusions:

• Early seizure recurrence is common in hospitalized dogs, occurring within a mean of 7 hours.
• Dogs presenting with abnormal neurological exams and a history of cluster seizures or status epilepticus within 72 hours should be considered for ICU admission.
