The remaining dogs with IE with another cause of death had a survival time of 4.7 years after the initial seizure. Some of the questions were adopted from a validated questionnaire (17), and additional questions were developed to evaluate death in dogs with epilepsy. A probable SUDEP (pSUDEP) lacks postmortem examination but complies with definite SUDEP: unexpected death in a reasonable state of health, during normal activities and in benign circumstances and without a known structural cause of death (9). described that during hospitalization 50% of dogs showed another seizure event within 7 h after in house placement (50).

In general, the seizure frequency showed no significant difference between the pSUDED group and the remaining dogs with IE (p = 0.09), in contrast to some human medicine studies, where the frequency of seizures and generalized tonic-clonic seizures are considered a decisive risk factor for SUDEP (4446).

Dogs with brachycephalic syndrome were overrepresented (3/12) in the pSUDED group and a odds ratio of 3.68 was calculated. There is a 1.63-fold increase in standardized mortality rate (SMR) in human patients with epilepsy compared to the general population (1). : On the one hand, death should occur within 1 h of the last seizure event to be called SUDEP (9). What Is Brachycephalic Syndrome in Boston Terriers? In addition to regular vaccination, I typically recommend annual heartworm testing and administering monthly heartworm preventative to prevent heartworm infection. Idiopathic epilepsy (IE) is described as an exclusion diagnosis for dogs of a certain age group with recurrent seizures without an underlying structural cause, but with a (presumed) genetic influence (25, 26).

The occurrence rate of pSUDED cases in this study population was calculated and compared with the percentage of all deceased dogs with IE presented to our clinic in the last 20 years. Furthermore, therapy resistant or poorly controlled chronic seizures, GTCS, and a high seizure frequency in human medicine are suspected risk factors (60). In younger Boston Terriers, one of the most common causes of death is infectious diseases. In human medicine, status epilepticus is defined as a seizure duration exceeding 30 min (47).
