About the FCRSA
Epilepsy refers to abnormal electrical activity in the brain resulting in seizures or convulsions. Brain cells called neurons are responsible for transmitting information. They communicate with one another by way of chemically-mediated electrical impulses. When too many neurons discharge their impulses simultaneously a seizure may result. The type of seizure produced depends on the location in the brain where the abnormal electrical activity occurs. There are two types of epilepsy. Primary epilepsy (also called idiopathic, inherited or true epilepsy) is the type for which no real cause can be found. Secondary epilepsy can be attributed to such things as toxins (oftentimes, lead), metabolic disorders (low blood sugar is a common cause), nutritional deficiencies, head injuries, brain tumors, etc. Seizures are also categorized by the type of activity produced. Dogs with primary epilepsy most often exhibit generalized seizure activity called a tonic-clonic seizure. The entire body is involved. The tonic phase is the period in which the dogs falls, assumes a rigid posture, becomes unconscious and stops breathing. This usually lasts 10-30 seconds. Then the clonic phase begins in which the dog's limbs exhibit a paddling motion. During the seizure, the dog may lose control of its bowel or bladder and salivate profusely. A partial seizure will affect only one area of the body. These are usually associated with secondary epilepsy. Status epilepticus is a seizure of abnormally long duration and is a medical emergency as the dog may stop breathing for a longer period of time. Clusters of seizures may also do the same thing. Both result in low blood oxygen and can produce permanent brain damage or death.
