犬癫痫：发作时该做什么、不该做什么，以及长期用药的现实
2026/10/3· 约 4 分钟读完· 26 个要点
癫痫发作看起来吓人，但主人当场做错事的伤害往往更大。这篇按国际兽医癫痫工作组（IVETF）共识，讲清发作处置、诊断分层与长期用药目标。
一、发作现场：做对三件事
- 计时：超过 5 分钟或短时间内反复发作 = 急症，立即送医；
- 保护，不约束：移开周围硬物/锐物，降低跌落风险，不要把手或物品放进嘴里（犬不会咬到舌头致死，但你会被误伤）；
- 减少刺激：关灯、降低声音、不要喊叫摇晃。
发作后（发作后期）犬可能暂时失明、踉跄、意识混乱——不要此时喂食喂水，避免误吸。
二、诊断是分层做的
IVETF 共识把诊断分成层级：先确认是否真是癫痫发作、再区分结构性癫痫（脑内有病灶）与特发性癫痫、并按病因做相应检查（血液生化、胆汁酸、MRI/脑脊液等）[1]。
特发性癫痫通常在 6 个月—6 岁起病、发作间期神经检查正常，是排除性诊断——也就是说，"查出来没问题"本身就是诊断依据的一部分。
三、什么时候开始长期用药
IVETF 用药共识给出的指征不是"发作过一次就吃药"，而是综合发作频率、严重程度（丛集性发作/癫痫持续状态）、发作后期表现与主人可接受性[2]。目标是：
- 减少发作频率与严重程度，而不是追求"一次都不发"；
- 接受药物不良反应与监测成本之间的平衡；
- 规律性服药比剂量本身更重要（漏服是诱发丛集发作的常见原因）。

This article outlines the consensus proposal on diagnosis of epilepsy in dogs by the International Veterinary Epilepsy Task Force. The aim of this consensus proposal is to improve consistency in the diagnosis of epilepsy in the clinical and research settings. The diagnostic approach to the patient presenting with a history of suspected epileptic seizures incorporates two fundamental steps: to establish if the events the animal is demonstrating truly represent epileptic seizures and if so, to identify their underlying cause. Differentiation of epileptic seizures from other non-epileptic episodic paroxysmal events can be challenging. Criteria that can be used to make this differentiation are presented in detail and discussed. Criteria for the diagnosis of idiopathic epilepsy (IE) are described in a three-tier system. Tier I confidence level for the diagnosis of IE is based on a history of two or more unprovoked epileptic seizures occurring at least 24 h apart, age at epileptic seizure onset of between six months and six years, unremarkable inter-ictal physical and neurological examination, and no significant abnormalities on minimum data base blood tests and urinalysis. Tier II confidence level for the diagnosis of IE is based on the factors listed in tier I and unremarkable fasting and post-prandial bile acids, magnetic resonance imaging (MRI) of the brain (based on an epilepsy-specific brain MRI protocol) and cerebrospinal fluid (CSF) analysis. Tier III confidence level for the diagnosis of IE is based on the factors listed in tier I and II and identification of electroencephalographic abnormalities characteristic for seizure disorders. The authors recommend performing MRI of the brain and routine CSF analysis, after exclusion of reactive seizures, in dogs with age at epileptic seizure onset <6 months or >6 years, inter-ictal neurological abnormalities consistent with intracranial neurolocalisation, status epilepticus or cluster seizure at epileptic seizure onset, or a previous presumptive diagnosis of IE and drug-resistance with a single antiepileptic drug titrated to the highest tolerable dose.This consensus article represents the basis for a more standardised diagnostic approach to the seizure patient. These recommendations will evolve over time with advances in neuroimaging, electroencephalography, and molecular genetics of canine epilepsy.
