The aetiology and outcome of dogs with juvenile-onset seizures were investigated. One hundred and thirty-six dogs whose first seizure occurred before the age of one year were investigated. One hundred and two dogs were diagnosed with idiopathic epilepsy (IE), 23 with symptomatic epilepsy (SE), nine with reactive seizures (RS) and two with probable symptomatic epilepsy (pSE). The outcome was known in 114 dogs; 37 per cent died or were euthanased as a consequence of seizures. The mean survival time of this population of dogs was 7.1 years. Factors that were significantly associated with survival outcome included the diagnosis of SE and the number of antiepileptic drugs (AEDs) used before investigation. The use of one AED before investigation and a diagnosis of SE were associated with a negative outcome, whereas receiving no AED medications before referral was associated with a longer survival. For dogs with IE, survival time was shortened if the dog was a border collie or with a history of status epilepticus;receiving no AEDs before referral in the IE group was associated with a positive outcome. Seizure-free status was achieved in 22 per cent of dogs diagnosed with IE. While the survival times were longer than previously reported in canine epilepsy, similar remission rates to those reported in childhood epilepsy, where a 70 per cent remission rate is documented, were not seen in the canine juvenile population.  相似文献

The medical records of 50 dogs that exhibited generalised convulsive tonic-clonic (GCTC) status epilepticus (SE) were reviewed and compared with the records of 50 dogs that exhibited non-SE GCTC seizures. The mean age, bodyweight and gender of the patients in both groups were not significantly different. Dogs in the non-SE group were two times more likely to be an idiopathic epileptic than to have secondary epileptic seizures. The SE group was more likely to have abnormalities on cerebrospinal fluid analysis, but not more likely to have abnormalities detected on computed tomography, when compared with the non-SE group. SE was 1.57 times more likely if the cause for the seizures was secondary or reactive epilepsy rather than idiopathic or primary epilepsy. In conclusion, dogs that exhibit SE should be thoroughly investigated for secondary causes.  相似文献

Background: A special form of epileptic seizures (ES) is the life-threatening condition of status epilepticus (SE), which requires immediate and specific treatment based on a correct diagnosis of the underlying disease condition.
Hypothesis/Objectives: The objectives of this retrospective study were to determine prevalence of ES and SE in dogs presenting at a veterinary teaching hospital, to identify the etiology and relative risk (RR) for SE in general and at the onset of seizures. Furthermore the outcome for dogs suffering from SE was to be evaluated.
Animals: Three hundred and ninety-four dogs that were admitted to a veterinary teaching hospital (January 1, 2002 to March 31, 2008) with ES.
Methods: All medical records of dogs with ES were identified by screening the clinical documentation system and evaluated for inclusion in this retrospective study.
Results: Dogs with reactive seizures caused by poisoning had a significantly higher risk of developing SE ( P < .001; RR = 2.74), particularly as 1st manifestation of a seizure disorder ( P = .001; RR = 1.97). After SE, dogs with symptomatic epilepsy had a significantly lower probability of survival than dogs with idiopathic epilepsy ( P < .001) and reactive ESs ( P = .005).
Conclusion and Clinical Importance: In dogs showing SE as the 1st manifestation of a seizure disorder, intoxication should always be considered and appropriate investigations undertaken. Dogs with SE owing to toxicosis have more favorable outcomes than dogs with symptomatic epilepsy ( P < .001).  相似文献

The human definitions of epilepsy and seizure classification were applied rigidly to epileptic dogs to investigate whether the distribution of the seizure types and epilepsies of dogs is comparable to that of human beings. Sixty-three dogs were referred because of recurrent (> 2) epileptic seizures. Only dogs without previous or ongoing antiepileptic treatment were included. All dogs had a physical and neurologic examination and blood work that included a CBC and a biochemical profile. All owners were asked to complete a questionnaire, focusing on seizure development. In addition, video recordings of suspected seizure episodes were analyzed if available. In the majority of dogs where an intracranial lesion was suspected, a computerized tomography scan was performed. Sixty-five percent of the dogs experienced partial seizures with or without secondary generalization and 32% exhibited primary generalized seizures; in 3% of the dogs the seizures could not be classified. Twenty-five percent of these cases were classified as idiopathic, 16% as symptomatic, and 45% as cryptogenic epilepsy; in 14% of these a classification was not possible. Applying human definitions, the distribution of seizure types and epilepsy classifications in these dogs differed widely from those in previous reports of canine epilepsy, where generalized seizures and idiopathic epilepsy were most frequently reported. However, our findings are consistent with the results of several large studies of human epilepsy patients. In dogs with epilepsy, closer attention must be given to the detection of a partial onset of seizures. In this study, detailed questioning of the owners and when possible analysis of video recorded seizures, proved to be sufficient for diagnosing seizures with a partial onset in a significant number of dogs. Partial onset of seizures may be an indication of underlying cerebral pathology. Some adjustments of veterinary epilepsy terminology are suggested.  相似文献

Objective – To describe outcome of treatment with propofol and phenobarbital for status epilepticus (SE) after portosystemic shunt (PSS) attenuation. Case or Series Summary – Three dogs without preceding seizure activity, were diagnosed with a single extrahepatic PSS. Following standard preoperative medical therapy, an ameroid constrictor was placed surgically. Recovery was uneventful until spontaneous SE developed 46–96 hours after surgery. After unsuccessful seizure control with benzodiazepines, dogs were treated with a bolus of propofol followed by a propofol constant rate infusion. Phenobarbital was concurrently administered and supportive care was optimized. All dogs recovered uneventfully over the next 7–9 days. Over the following months phenobarbital was slowly tapered. All dogs have been free from antiepileptic drugs for several months, without recurrence of neurologic signs. New or Unique Information Provided – In this case series, we describe the treatment of 3 dogs with propofol and phenobarbital for refractory SE following attenuation of a single congenital PSS. After weaning of the propofol constant rate infusion, and tapering and discontinuation of phenobarbital over the following months, all dogs experienced a complete recovery. This study provides evidence that use of propofol in combination with phenobarbital may be efficacious for management of SE in dogs after PSS surgery.  相似文献

OBJECTIVE: To report clinical findings, treatments, and outcomes of dogs admitted to the hospital for status epilepticus or cluster seizures and evaluate factors associated with outcome. DESIGN: Retrospective study. ANIMALS: 156 dogs admitted for status epilepticus or cluster seizures. PROCEDURE: Medical records were reviewed for seizure and medication history, diagnostic test results, types of treatment, hospitalization costs, and outcome of hospital visits. RESULTS: Dogs were admitted for seizures on 194 occasions. Of 194 admissions, 128 (66%), 2 (1%), 32 (16.5%), 2 (1%), and 30 (15.5%) were of dogs with a history of clusters of generalized seizures, clusters of partial complex seizures, convulsive status epilepticus, partial status epilepticus, and > 1 type of seizure, respectively. Underlying causes of seizures were primary epilepsy (26.8%; 52/194), secondary epilepsy (35.1%; 68), reactive epileptic seizures (6.7%; 13), primary or secondary epilepsy with low serum antiepileptic drug concentrations (5.7%; 11), and undetermined (25.8%; 50). One hundred and eighty-six hospital visits resulted in admission to the intensive care unit (ICU). Treatments with continuous i.v. infusions of diazepam or phenobarbital were initiated during 66.8% (124/186) and 18.7% (35) of ICU hospital stays for 22.3 +/- 16.1 hours (mean +/- SD) and 21.9 +/- 15.4 hours, respectively. Of 194 admissions, 74.7% (145) resulted in discharge from the hospital, 2.1% (4) in death, and 23.2% (45) in euthanasia. A poor outcome (death or euthanasia) was significantly associated with granulomatous meningoencephalitis, loss of seizure control after 6 hours of hospitalization, and the development of partial status epilepticus. CONCLUSIONS AND CLINICAL RELEVANCE: Granulomatous meningoencephalitis, loss of seizure control after 6 hours of hospitalization, or the development of partial status epilepticus may indicate a poor prognosis for dogs with seizures.  相似文献

The aim of the present study was to investigate if prolonged status epilepticus (SE), secondary to a chemoconvulsant, can induce spontaneous recurrent seizures in dogs. Clinical records at two UK referral hospitals were searched for dogs that presented in SE secondary to intoxication. Dogs were only included in the study if there was clear historical evidence of intoxication and a prolonged SE. Clinical and follow-up information was retrieved and verified by using a combination of clinical records from the two hospitals and the referring veterinarian and by contacting the owners using a telephone questionnaire. Twenty dogs met the inclusion criteria: 17 presented for metaldehyde toxicity, one for moxidectin toxicity, one for theobromine toxicity and one for mycotoxin toxicity. Of these 20 dogs, three dogs had an SE duration between 0.5 and one hour, four dogs between one and 12 hours, 10 dogs between 12 and 24 hours and three dogs greater then 24 hours. Median follow-up time for the 20 dogs was 757 days (range 66 to 1663 days). No dog had any further seizures after its SE. The present study supports the view that dogs with a prolonged SE following intoxication with the aforementioned toxins might not need long-term treatment with antiepileptic drugs after the SE has been controlled.  相似文献

Background

Although a common neurological disorder in dogs, long‐term outcome of epilepsy is sparsely documented.

Objectives

To investigate risk factors for survival and duration of survival in a population of dogs with idiopathic epilepsy or epilepsy associated with a known intracranial cause.

Animals

One hundred and two client owned dogs; 78 dogs with idiopathic epilepsy and 24 dogs with epilepsy associated with a known intracranial cause.

Methods

A retrospective hospital based study with follow‐up. Dogs diagnosed with epilepsy between 2002 and 2008 were enrolled in the study. Owners were interviewed by telephone using a structured questionnaire addressing epilepsy status, treatment, death/alive, and cause of death.

Results

Median life span was 7.6 years, 9.2 years, and 5.8 years for all dogs, and dogs with idiopathic epilepsy or dogs with epilepsy associated with a known intracranial cause (P < .001), respectively. Survival time for dogs with idiopathic epilepsy was significantly (P = .0030) decreased for dogs euthanized because of epilepsy (median: 35 months) compared to dogs euthanized for other reasons (median: 67.5 months). Neutered male dogs with idiopathic epilepsy had a significant (P = .031) shorter survival (median: 38.5 months) after index seizure compared to intact male dogs (median: 71 months). Treatment with two antiepileptic drugs (AED′s) did not negatively influence survival (P = .056).

Conclusion and Clinical Importance

Dogs with idiopathic epilepsy can in many cases expect a life span close to what is reported for dogs in general. In dogs where mono‐therapy is not sufficient, the need for treatment with two AED′s is not linked to a poor prognosis.  相似文献

OBJECTIVES: To explore seizure management from the perspective of the owners of dogs with idiopathic epilepsy. METHODS: Questionnaires were mailed to owners of 29 dogs under management for suspected or diagnosed idiopathic epilepsy through the clinics of the Small Animal Hospital of the University of Glasgow Veterinary School, using either phenobarbitone or potassium bromide alone or in combination. RESULTS: The postal survey had an 86 per cent response rate. Analysis of the responses demonstrated that "the dog's quality of life", "adequate seizure frequency" and "acceptable side effects of antiepileptic drugs" were the three greatest concerns for owners; 52 per cent of owners strongly agreed that the seizure management for their dog was adequate, though the seizure frequency reported varied within this group; the majority of owners did not consider the administration of medication a nuisance. However, approximately 60 per cent of owners reported that caring for an epileptic dog had an effect on the organisation of their free time, though this was not dependent on perception of seizure control. Opinions as to the value of further diagnostic procedures, in particular intracranial imaging, were significantly affected by having pet health insurance. CLINICAL SIGNIFICANCE: From the owners' perspective, adequacy of seizure control is determined by the balance between "the dog's quality of life", "adequate seizure frequency" and "acceptable side effects of antiepileptic drugs". A frequency of less than one seizure every three months is associated with the perception by owners of adequate seizure control.  相似文献

We evaluated the feasibility of interictal single photon emission computed tomography (SPECT) to detect alterations in regional cerebral blood flow and neuronal activity in dogs with idiopathic epilepsy. Twelve dogs with idiopathic epilepsy underwent interictal technetium-99m-ethyl cysteinate dimer SPECT of the brain. Different cortical regions of interest (ROIs), 1 ROI at the cerebellum and 1 ROI at the subcortical area were evaluated by semiquantitative analysis and compared with a control group (18 dogs). Significant hypoperfusion ( P =0.02) was present in the subcortical area of epileptic dogs. This hypoperfusion was not associated with seizure frequency, age at onset of seizures, duration of epilepsy, or time since the last seizure. Interictal SPECT did not reveal cortical or cerebellar perfusion alterations. The subcortical area may play an important role in the pathophysiology of canine idiopathic epilepsy.  相似文献

BackgroundStatus epilepticus (SE) is an emergency associated with serious consequences for both patient and owner. Data regarding risk factors for short‐term mortality or recurrence in dogs with SE is limited.ObjectiveIdentify risk factors associated with short‐term mortality (euthanasia or spontaneous death) and recurrence of SE in dogs.AnimalsOne hundred twenty‐four client‐owned dogs that sustained an episode of SE.MethodsRetrospective multicenter study using data collected from medical records of dogs presented in SE to the contributing institutions. Multivariable logistic regression analysis was performed using a manual backwards stepwise approach to identify risk factors associated with short‐term mortality and recurrence of SE after discharge.ResultsShort‐term mortality for affected dogs was 29.8%. Factors significantly associated with short‐term mortality included increased patient age, shorter duration of hospitalization, development of SE before arrival, and SE caused by a potentially fatal etiology. Status epilepticus recurred in 27% of dogs that survived to discharge. Factors significantly associated with recurrence of SE included prior history of pharmacoresistant epilepsy and predominance of a focal seizure phenotype.Conclusions and Clinical ImportanceOur results may be used to inform clinicians and dog owners regarding risk factors for both short‐term mortality and recurrence in dogs with SE.  相似文献

Background: There is a lack of data on idiopathic epilepsy (IE) in Border Collies (BCs) in the veterinary literature.
Hypothesis: Genetic epilepsy occurs in BCs and is frequently characterized by a severe clinical course and poor response to medical treatment.
Animals: Forty-nine BCs diagnosed with IE.
Methods: Medical records, seizure data, treatment data, and pedigree information of affected dogs were collected. Cases were classified phenotypically as affected or not affected; mild, moderate, or severe clinical course; active epilepsy (AE) or remission; and drug resistant or not drug resistant.
Results: Clinical manifestations were classified as having a moderate (33%) or severe clinical course (49%), characterized by a high prevalence of cluster seizures and status epilepticus. Survival time was significantly decreased in dogs <2 years of age at seizure onset, and in dogs with a severe clinical course. Drug resistance was apparent in 71% of 24 dogs treated with ≥2 antiepileptic drugs. The epilepsy remission rate was 18%. Median age at onset was significantly higher and initial seizure frequency was significantly lower in dogs with remission compared with dogs with AE. Pedigree analyses indicated a strong genetic founder effect in the appearance of epilepsy, resembling autosomal recessive inheritance.
Conclusion and Clinical Importance: The present study confirms the occurrence of genetically mediated epilepsy with a frequent severe clinical course and drug resistance in BCs. The results provide information about the long-term prognosis of IE in BCs for veterinarians and concerned owners, and may benefit breeders as well.  相似文献

Background

Catamenial epilepsy in humans is defined as changes in seizure frequency over the course of the menstrual cycle. Three hormonally based patterns of seizure exacerbation have been determined.

Objectives

The aim of this study was to evaluate whether there is an association between onset of seizures and the estrous cycle in intact bitches with presumptive idiopathic epilepsy and whether a pattern to the onset of seizures could be recognized.

Animals

Forty‐five intact female dogs from a hospital population with a presumptive diagnosis of idiopathic epilepsy.

Methods

In a retrospective study, the database of a small animal hospital in Sweden was searched for medical records of intact female dogs diagnosed with epilepsy or seizures. The stage of the estrous cycle as reported either by the owner or the veterinarian at the time of the first seizure was noted.

Results

Of the 45 dogs with idiopathic epilepsy, 17 (38%) had their first seizure when in heat and six dogs (13%) had their first seizure 1–3 months after heat. Nine dogs (20%) had seizures reoccurring in relation to their estrous cycle.

Conclusions and Clinical Importance

These findings suggest an association between estrus and onset of seizures in intact bitches with presumptive idiopathic epilepsy. Two hormonally based patterns could be recognized: one during heat and one during a specific time point at the end of diestrus. This could be explained by the proconvulsive effects of estrogen or loss of protective effect against seizures of progesterone, respectively.  相似文献

The effects of essential fatty acid supplementation (EFA) on the control of idiopathic epilepsy in dogs were investigated in a blinded, placebo-controlled trial. Fifteen dogs were treated with triple purified Ω-3 oil containing 400 mg eicosapentaenoic acid, 250 mg docosahexaenoic acid and 22 mg vitamin E per 1.5 mL at a dose of 1.5 mL/10 kg once daily for 12 weeks, followed by a 12 week placebo period of supplementation with olive oil. Owners recorded seizure frequency and severity and any adverse events. EFA supplementation did not reduce seizure frequency or severity in dogs with idiopathic epilepsy.  相似文献

O bjectives : Investigation of the efficacy of zonisamide as an add-on therapy in dogs with refractory epilepsy.
M ethods : Thirteen dogs fulfilled the inclusion criteria of poor seizure control despite adequate serum levels of phenobarbital, potassium bromide or both. One further dog was treated with zonisamide as monotherapy because of severe blood dyscrasia due to phenobarbital treatment. Various seizure parameters were evaluated retrospectively for a four month period without zonisamide and prospectively for the same time period under zonisamide add-on therapy. The study time period was extended by up to 17 months to evaluate long-term outcome.
R esults : Data of 11 dogs could be evaluated: nine of them were responders. The median reduction of seizure frequency of all dogs on zonisamide add-on therapy was 70 per cent (range 14 to 100 per cent). Only transient central nervous system side effects were reported. No further increase of liver enzymes occurred. In three of the responder dogs, seizure control subsided after individual time periods (between 69 days and seven months).
C linical S ignificance : In dogs with refractory epilepsy, zonisamide may have a beneficial effect on seizure control. In three responder dogs, seizure activity relapsed possibly because of an induction of tolerance. Limiting factors are the high costs.  相似文献

A new antiepileptic and anxiolytic drug, ELB138, was evaluated in a clinical pilot study in dogs with newly diagnosed or chronic idiopathic epilepsy. The purpose was to verify clinically the anticonvulsant effectiveness of this substance, which had already been demonstrated experimentally. Data from 29 dogs treated with ELB138 were compared with results obtained retrospectively from 82 dogs treated with conventional antiepileptic medication. The reduction in seizure frequency using ELB138 in dogs with newly diagnosed idiopathic epilepsy was comparable to the reduction in dogs treated either with phenobarbital or primidone. In dogs with chronic epilepsy and add-on therapy with either ELB138 or potassium bromide, such supplementation reduced the seizure frequency and the duration and severity of seizures. The most obvious difference between ELB138 treatment and conventional medications became clear in the evaluation of side effects, which in those dogs treated with ELB138 were rare, and consisted mostly of transient polyphagia. This pilot study confirmed that ELB138 has a potent anticonvulsant effect in dogs with idiopathic epilepsy. These results will form the basis for a multicentre, blinded study.  相似文献

Objective – To describe the use of continuous electroencephalographic (EEG) monitoring for management of status epilepticus (SE) in dogs and cats. Design – Retrospective study. Setting – University teaching hospital. Animals – Ten patients (7 dogs, 3 cats) with SE of differing etiology (idiopathic epilepsy, n=3; toxicity, n=4; meningoencephalitis, n=2; undefined, n=1). Interventions – The EEG was recorded continuously from 5 stainless‐steel needle electrodes inserted SC. Animals were treated with diazepam and phenobarbital followed by either propofol (n=3) or pentobarbital (n=7) as a continuous rate of infusion. Measurements and Main Results – Clinical seizures stopped after induction of anesthesia in each animal. The EEG, however, still showed distinct epileptiform patterns (spikes, polyspikes) in all animals. Paroxysms were suppressed by increasing the infusion rate of either pentobarbital or propofol. A burst‐suppression pattern was achieved in 5 animals. EEG epileptiform activity reappeared in 4 animals when attempting to taper the dose after >6 hours of anesthesia. This was interpreted as ongoing EEG seizure activity and an increased risk for clinical seizures, and the anesthetic dosage was adjusted accordingly. Conclusion – Continuous EEG monitoring appears to be a useful tool for therapeutic monitoring of SE in dogs and cats. It allows the detection of EEG seizures without the appearance of clinical seizures. Further investigations with blinded investigators and homogeneous animal groups to define therapeutic endpoints are warranted.  相似文献

Euthyroid sick syndrome is a common finding in dogs and is attributable to nonthyroidal illness or treatment with any of a variety of drugs such as phenobarbital. In dogs with epilepsy, treatment with anticonvulsant drugs can lead to subnormal plasma thyroid hormone concentrations despite normal thyroid function. One-hundred thirteen dogs with seizure activity were retrospectively evaluated to determine the influence of idiopathic epilepsy (IE) on thyroid hormone concentrations. Blood samples were taken from 60 dogs with IE before initiation of anticonvulsant therapy. Control groups consisted of 34 dogs with IE and receiving anticonvulsants and 19 dogs with secondary epilepsy. Thyroid concentrations consistent with euthyroid sick syndrome were diagnosed in 38% of dogs with untreated IE without clinical signs of hypothyroidism or concomitant diseases. There was a significant correlation (r = 0.363, P = .01) between seizure frequency and plasma thyroid hormone concentrations: the longer the interval between 2 seizure events, the higher the serum total thyroxine concentration. There was no correlation between the degree of alteration of thyroid hormone concentrations and the time span between the most recent seizure event and blood collection, the type of the most recent seizure event, the duration of the complete seizure history, or the predominant seizure type. These results suggest that IE can be a reason for euthyroid sick syndrome in dogs. The effect of phenobarbital on plasma thyroid hormone concentrations must be investigated in future studies, as it might be less pronounced than expected.  相似文献

BACKGROUND: Granulomatous meningoencephalomyelitis (GME) is an idiopathic inflammatory disease of the central nervous system. Remission often is short-lived in dogs treated with glucocorticoids. Procarbazine is T cell-specific and crosses the blood-brain barrier. HYPOTHESIS: Dogs with presumptive antemortem diagnosis of GME given procarbazine as adjunctive therapy to prednisone will have improved long-term outcome compared with dogs given no treatment or glucocorticoids alone. ANIMALS: Two groups were studied: (1) Dogs with presumptive antemortem diagnosis of GME treated with procarbazine and prednisone (n = 21); (2) Dogs that had a histologic diagnosis of GME at postmortem examination and received no treatment (n = 11). METHODS: Dogs with presumptive GME treated with procarbazine were identified retrospectively from medical records of 2 veterinary referral hospitals. Selection criteria required all dogs have a neurologic examination, blood work, cerebrospinal fluid analysis, and brain imaging (MRI or CT). RESULTS: Median survival time for all dogs studied was 5.0 months. Median survival time for dogs treated with procarbazine was 14.0 months and for untreated dogs, 0.73 months. Treatment with procarbazine was significantly correlated with survival time (P < .001). Procarbazine was the only independent predictor of survival. Prednisone was reduced in dosage or discontinued in 17 dogs. Adverse reactions to procarbazine therapy included myelosuppression in 7 dogs and hemorrhagic gastroenteritis in 3 dogs. CONCLUSION: These data suggest that procarbazine treatment of presumptive GME may result in greater improved long-term outcome than has been previously reported for glucocorticoid treatment alone and may complement other immunomodulatory therapies. Procarbazine-treated dogs must be monitored for adverse reactions.  相似文献

The use of diazepam per rectum (RDZ) in the home to control generalized cluster seizures in 11 dogs diagnosed with idiopathic epilepsy was evaluated over a 16-month period. All dogs had a prior history of clusters of generalized seizures and were treated with multiple antiepileptic drugs. Owners were instructed to administer diazepam injectable solution (5 mg/mL) per rectum to their dogs at a dose of 0.5 mg/kg when an initial generalized seizure occurred and when a second or third generalized seizure occurred within 24 hours of the first seizure. Seizure activity was recorded by owners in a daily log before the onset of RDZ use and for the duration of RDZ use, which ranged from 57 to 464 days (median = 157 days). The median age at which the first seizure occurred and the median age at the time of enrollment in the study were 19 and 42 months, respectively. All 11 dogs were treated with phenobarbital, with 10 dogs receiving concomitant bromide therapy. No significant correlation between the duration of the first, second, or third antiepileptic drug therapy and the change in the number of cluster seizure events before or after use of RDZ was found. Comparisons of seizure activity were done for the same time interval before and after the onset of RDZ availability. A significant decrease in the total number of seizure events and the total number of cluster seizures events was found after RDZ availability. Similarly, a significant difference in the average number of seizures per cluster seizure event and the total number of isolated seizure events occurred before and after RDZ therapy. Eight of the 11 dogs (73%) that received RDZ for 1 or more times after the first or second seizure had a 100% success rate in prevention of further seizure activity after the first dose. In 3 dogs, success and compliance rates were both equal at 100%, thus suggesting 100% efficacy of RDZ in blocking further seizure activity over the next 24 hours in these dogs. Owners had a large cost-savings because of the decrease in emergency clinic visits after initiating treatment with RDZ. Before RDZ use, the average number of emergency clinic visits was 3, with an average cost of $308 per dog. After RDZ use, the average number of emergency clinic visits was 1, with an average cost of $81 per dog. The results of this study suggest that RDZ may be an effective method of home treatment of generalized cluster seizures in dogs with idiopathic epilepsy, regardless of prior antiepileptic drug history.  相似文献
