A seizure is a temporary disturbance in brain function caused by uncontrolled electrical activity. It can manifest as a generalized event with loss of consciousness and convulsions, or as focal twitching. Causes range from idiopathic epilepsy to toxins, brain tumors, or metabolic imbalances.
This condition requires veterinary attention.
If your animal shows the Key or Common signs listed, please visit a clinic immediately.
Report Case / Get HelpSeizures themselves are not contagious. However, if the underlying cause is an infectious disease like Distemper or Rabies, that underlying agent may be transmissible.
A seizure episode has three distinct phases: the 'aura' or pre-ictal phase where behavior changes; the 'ictus' which is the seizure itself; and the post-ictal phase characterized by confusion, blindness, and exhaustion.
Diagnosis is a process of exclusion, starting with blood work to rule out metabolic causes. Advanced imaging like MRI and CSF analysis may be required to detect structural brain abnormalities.
Emergency treatment utilizes Diazepam to stop active seizures. Long-term management for epilepsy involves daily anticonvulsant medications like Phenobarbital or Levetiracetam to reduce the frequency and severity of episodes.
Prevention depends on the cause; avoiding known toxins is crucial. For epileptic animals, strict adherence to the medication schedule prevents breakthrough seizures.
The prognosis depends heavily on the underlying cause. Idiopathic epilepsy is often manageable with lifelong medication, while seizures caused by brain tumors carry a poorer outlook.
