Introduction: Intracranial dermoid cysts (IDCs) are rarely observed in veterinary medicine, and reports regarding treatment strategies for feline IDCs are severely lacking. This report describes the surgical management of epileptic seizures caused by IDCs in a cat.
Case Presentation: An 8-year-old, spayed, female American Shorthair cat presented with epileptic seizures. The epileptic seizures, which had developed at the age of 5 years, had been controlled by phenobarbital administration. At 8 years old, the cat contracted acute hepatitis, prompting a switch from phenobarbital to other antiseizure medications. This drug switch caused an increase in the frequency of epileptic seizures. Magnetic resonance imaging (MRI) revealed a dermoid cyst as a heterogeneous intensity mass on T2-weighted images, without falx cerebri displacement. The preoperative seizures occurred more than three times a day (cluster seizures), even though the cat was administered multiple antiseizure medications. The seizures ceased after surgical removal of the dermoid cyst. The cat did not experience seizures for 14 months after surgery, even with discontinuation of antiseizure medications.
Conclusion: In cats, surgical removal of frontal lobe IDCs may effectively control epileptic seizures without fatal complications, thus potentially leading to a great prognosis.

Seizures, Driver Licensure, and Medical Reporting Update: An AAN Position Statement.

This consensus position statement of the American Academy of Neurology, American Epilepsy Society, and Epilepsy Foundation of America updates prior 1994 and 2007 position statements on seizures, driver licensure, and medical reporting. Key consensus positions include the following: (1) in the United States, national driving standards promulgated through a system such as the Uniform Law Commission would reduce confusion and improve adherence with state driving standards; (2) state licensing criteria for medical conditions should be promulgated by regulations and guidelines based on enabling legislation rather than in statutes themselves and should be developed by medical advisory boards working in collaboration with departments of motor vehicles; (3) licensing criteria should be equitable, nondiscriminatory, objective, and compatible with comparable risks in other populations; (4) a minimum seizure-free interval of 3 months should ordinarily be required before driving in all cases and should be extended in individual cases based on review of favorable and unfavorable features by medical advisory boards; (5) individuals with exclusively provoked seizures attributable to provoking factors that are unlikely to reoccur in the future may not require a seizure-free interval before resuming driving; (6) individuals with previously well-controlled epilepsy who experience seizures due to short-term interruptions of antiseizure medications in the setting of hospitalization or practitioner-directed medication-titration may not require a seizure-free interval before driving once previously effective levels of antiseizure medications have been resumed; (7) patients and practitioners should pause driving during tapering and following discontinuation of an antiseizure medication if another such medication is not introduced; (8) individuals whose cognition or coordination is impaired due to medications used to prevent seizures should refrain from driving; (9) health care practitioners should be allowed but not mandated to report drivers who pose an elevated risk; but (10) neither a decision to report a patient suspected of being at elevated risk nor a decision declining to report a patient suspected of being at elevated risk should be subject to legal liability; (11) nations, states, and municipalities should provide alternative methods of transportation and accommodations for individuals whose driving privileges are restricted due to medical conditions.

A systematic review using PRISMA criteria was used to review the literature regarding the specific semiology of seizure arising (a) from the temporal pole or (b) from both medial and lateral temporal cortex. Evidence was analyzed with regard to information provided by intracranial EEG recordings and surgical outcomes, and an estimation of validity of reported signs and symptoms was performed. Semiology of seizures originating from the temporal pole was mostly related to diverse patterns of ictal spread rather than to the localization of seizure origin and comprised a wide variety of early signs and symptoms.

Kindling is an experimental-induced seizure consistent with epilepsy disease, a chronic neurological disorder characterised by spontaneous and repeated seizures. This disease is associated with oxidative stress, and most therapeutic strategies against epilepsy aim at improving the antioxidant defence mechanism in the brain. However, prolonged usage and associated adverse side effects limit antiepileptics, warranting natural antioxidant patronage.

The immune system is crucial for the correct brain development, and recent findings also point toward central control of immune response. As the immune system is not fully developed at birth, the early years become an important window for infections and for the development of epilepsy. Both central and even peripheral inflammation may impact brain function, promoting opening of the blood-brain/blood and cerebrospinal barriers and allowing entry of immune cells and cytokines, which in turn may affect neuron function and connections.
