Sorry to hear about Babygirl. Unfortunately, without advanced diagnostic imaging it will not be possible to tell you with certainly the cause of her seizure activity. An MRI would be the only way to accomplish this positively. Based on her age and no previous history of seizure activity, a brain tumor or tumor elsewhere in the central nervous system would be the most likely diagnosis. Much lower down on my list would be some sort of infectious or inflammatory process. Even lower would be extremely late onset epilepsy. Based on what you are telling me, it sounds like humane euthanasia is probably the best decision you can make for her. I know it's hard but I hope it gives you some solace knowing that you are bringing her to peace.

In an older animal who develops seizures, previously having had none, it is likely that something such as a brain tumour or organ failure is to blame as opposed to epilepsy. In this case if they are getting worse and she is showing neurological signs between seizures I would be suspicious of a tumour. Bloods could check for any issues with other organs. In the case of a brain tumour medication will likely be aimed towards making her more comfortable. Bearing in mind if signs are progressing quickly the prognosis will be poor. I would recommend taking her for an examination and bloods to help determine how severe the condition and decide on appropriate action.
