one way to determine whether a particular case is precipitated by underlying limbic seizure activity is to compare the differential effects of epileptogenic drugs and antiepileptic drugs on the expression of the behavior in question. Unfortunately, such pathology is difficult to diagnose through conventional EEG tests done to verify somatomotor epilepsy. In a few dogs the behavioral signs were the most prominent abnormality, appearing at times in the absence of generalized tonic-clonic seizures. such changes usually lasted a few hours at most, but were occasionally present for 3-4 days. The behavioral abnormalities consisted of: wandering in circles, restlessness, somnolence, apparent blindness, viciousness, inappropriate barking, attacking inanimate objects, terror-stricken behavior, inappetence, voracious appetite, generalized trembling, champing of the jaws, licking movements, and behaviour as if one ear were painful. As the result of interviews taken with owners, they detected a number of behavioral sequelae occurring co-morbidly with epilepsy in dogs, suggesting the possibility of a limbic system or temporal lobe involvement:īehavioral signs of varying duration and form were common before or after a generalized seizure or sometimes pre- and postictally. Holliday and coworkers (1970) studied 70 cases of canine motor epilepsy presenting with varying degrees of severity and duration. The amygdala is particularly sensitive to seizure activity, perhaps an etiologically significant factor in the development of some forms of panic disorder and generalized anxiety. Although behavior problems associated with fear and aggression are typically viewed as learned patterns, some such patterns may be (in part or whole) the behavioral manifestation of seizure activity in the hypothalamus, limbic system, or temporal lobes (Aronson, 1998). psychomotor seizure activity (limbic epilepsy) often presents with psychosomatic symptoms, like chronic vomiting or diarrhea (Reisner, 1991), and various behavioral signs. Epilepsy in cases of bizarre or unusual behavior occurring with little or no warning, one should suspect the possibility of a biological pathology involving the brain.
