Canine Epilepsy
Complex Partial Seizures (aka Psychomotor or Behavioral) Seizures: are associated with bizarre or complex behaviors that are repeated during each seizure. People with complex partial seizures experience distortions of thought, perception or emotion (usually fear), sometimes with unusual visual, olfactory, auditory and gustatory sensations. If dogs experience the same things, it may explain the lip-smacking, chewing, fly biting, aggression,
vocalization,
hysterical running, cowering or hiding in otherwise normal animals. Vomiting, diarrhea, abdominal distress,
salivation, blindness, unusual
thirst(Nisha is drinking a little more than usual..nothing major) or appetite, and flank biting are other signs. There is an
obvious lack of awareness though usually not lack of consciousness.
Abnormal behaviors may last minutes or hours and can be followed by a generalized seizure. Complex partial seizures are usually associated with secondary epilepsy.
Secondary epilepsy refers to seizures for which a cause can be determined, and there are many. In dogs less than one year of age, the most commonly-found causes of seizures can be broken down into the following classes: degenerative (storage diseases); developmental (hydrocephalus); toxic (lead, arsenic, organophosphates, chlorinated hydrocarbons, strychnine, tetanus); infectious (distemper, encephalitis, and others); metabolic (such as transient hypoglycemia, enzyme deficiency, liver or kidney failure); nutritional (thiamine, parasitism); and traumatic (acute injury). In dogs 1-3 years of age, a genetic factor is most highly suspected. In dogs 4 years of age and older, seizures are commonly found in the metabolic (hypoglycemia, cardiovascular arrhythmia, hypocalcemia, cirrhosis) and neoplastic (brain tumor) classes. (Oliver, Seizure). Dr. Jean Dodds has mentioned that seizures are also associated with hypothyroidism, which is a familial (inherited) autoimmune disease of purebred dogs.
