A strain of familial spontaneous epileptic cats (FSECs) with typical limbic seizures was identified in 2010. The electroencephalographic features suggested that an epileptogenic zone is present in the mesial temporal structures (i.e., amygdala and/or hippocampus). In this study, visual evaluations and quantitative analyses were performed by using 3D MR(More)
GM1 gangliosidosis is a fatal neurodegenerative lysosomal storage disease caused by an autosomal recessively inherited deficiency of β-galactosidase activity. Effective therapies need to be developed to treat the disease. In Shiba Inu dogs, one of the canine GM1 gangliosidosis models, neurological signs of the disease, including ataxia, start at(More)
A 10-year-old spayed female Abyssinian cat was presented with cluster limbic focal seizures with secondary generalisation. From magnetic resonance imaging (MRI) findings, the cat was diagnosed clinically as having a glioma in the left piriform lobe, and hypofractionated radiation therapy (RT) was performed using a linear accelerator. Although the tumour(More)
BACKGROUND Epilepsy is the most common neurological disease in veterinary practice. However, contrary to human medicine, epilepsy classification in veterinary medicine had not been clearly defined until recently. A number of reports on canine epilepsy have been published, reflecting in part updated proposals from the human epilepsy organization, the(More)
A feline strain of familial spontaneous epileptic cats (FSECs) with typical limbic seizures was identified in 2010, and have been maintained as a novel animal model of genetic epilepsy. In this study, we characterized the electroencephalographic (EEG) features of FSECs. On scalp EEG under sedation, FSECs showed sporadic, but comparatively frequent(More)
OBJECTIVE To evaluate the usefulness of diffusion and perfusion MRI of the cerebrum in cats with familial spontaneous epilepsy (FSECs) and identify microstructural and functional deficit zones in affected cats. ANIMALS 19 FSECs and 12 healthy cats. PROCEDURES Diffusion-weighted, diffusion tensor, and perfusion-weighted MRI of the cerebrum were performed(More)
OBJECTIVE The familial spontaneous epileptic cat (FSEC) is thought to be a good genetic model of mesial temporal lobe epilepsy. In the current study, cerebral diffusion and perfusion magnetic resonance imaging (MRI) were used to confirm the functional deficit zone in the FSEC and evaluate the effect of a single seizure on different brain regions. METHODS(More)
A 9 year-old, neutered, male French Bulldog showing cluster seizures was diagnosed with a glioma in the right piriform cortex by MRI. Hypofractionated radiation therapy (RT) was performed using a linear accelerator. Although the lesion had involuted significantly at 2 months after RT, recurrence was observed at 4 months after RT. Chemotherapy was started(More)
