Hi @kristinalynn
I am sorry you and your brother are going through such an experience.
In order to help us to help you, as @jakedduck1 has well put, we need to have a better understanding of what is happening to your brother, what types of seizures he had and has, the medications he is taking and what type of epilepsy he has. Is he being treated by a neurologist or an epileptologist?
You said he started to have random seizures after the loss of his caretaker, if I understood you correctly. Stress is well known as a major trigger of seizures. Does he need a caretaker? Does he have any other condition besides epilepsy?
I copy here a link to the major seizure triggers from the Epilepsy Foundation: https://www.epilepsy.com/what-is-epilepsy/seizure-triggers. The site of the Epilepsy Foundation is very complete and has been my school to learn more about my epilepsy, helping me a lot to find my way in the treatment of my epilepsy.
All the best!
