|There is definitely a connection between thyroid function and seizures. In some cases, hypothyroidism can cause seizures, and in other cases, the effect of epilepsy medication in controlling seizures unrelated to thyroid function depends indirectly on the function of the thyroid. So, even if hypothyroidism isn't the direct cause of seizures, it is possible that a malfunctioning thyroid can effect the ability of anti-seizure medications to work properly.
In addition to being epileptic, Gio is slightly hypothyroid and is on a low dose of thyroxine as a result.
While Lucca's tests seemed to come back pretty conclusive, many dogs that are hypothyroid go undiagnosed because vets are using general ranges to diagnose the disease. Gio's regular vet (now his ex-vet) refused to acknowledge that he is slightly hypothyroid because his numbers were technically within range. But when compared to the age, size, breed, and sex of the dog, and also taking into account the epileptic status, the ranges change and Gio is then deemed hypothyroid. So while this point isn't very important for Lucca as it was obvious in the test results that he is hypothyroid, other owners should be aware of this fact and ask to see the actual test results for themselves. If the numbers are in the low end of the "acceptable range", seek a second opinion! Ideally, sending the results off to Dr. Dodds at HemoPet.org for interpretation. Dr. Dodds has done a lot of research into the link between epilepsy and thyroid function and is able to interpret thyroid results taking into consideration all of the factors that may cause the acceptable range to change.
