There are many causes of seizures. Every case is different. There is no single cause. The only person that could answer your question is a Doctor Who is able to examine your grandfather and find out what the reason is in his case. Talk to your grandfather as he can tell you what the doctors have told him.
As stated below, every individual is different. However, speaking generally, sometimes older people develop epilepsy after:
Often, if it is caused from an underlying problem, the seizures will stop when the other problem is resolved.
NOTE: Epilepsy is not an illness you "get", and no one else near the person can "catch" it. Instead, Epilepsy is a condition that "develops".
Epilepsy is defined as the tendency of having recurring seizures. Seizures don't "turn into" epilepsy. Epilepsy is a broad ranging term that covers a range of things, but generally relating to the fact that someone has recurring seizures. If someone is having recurring seizures, then they should got to see a doctor and try to find out what is the cause of them, and get a formal diagnosis of their problem.
Not directly. If someone has Epilepsy it maybe as a result of some damage to the brain. If they have some damage to the brain, that may impair their ability to learn. In that situation, their epilepsy is just another symptom of the same thing that is causing their learning difficulties. Not everyone that has learning difficulties has epilepsy. Most people with epilepsy are well capable of learning and it has no impact on their capacity to learn. If their epilepsy causes them to miss out on regular education, which would only be with someone who has severe epilepsy, that will obviously affect their learning.
If someone gets recurring seizures, they are said to have epilepsy. The causes of individual seizures can be the same. It is just that someone only gets one once or a small amount of times. So causes could be a head injury, trauma, a temporary chemical imbalance in the brain, a brain tumour and many other things.
During a minor or what is called a petit mal seizure, someone can appear that way. More serious seizures will cause greater problems and someone may collapse or become unconscious. Epilepsy only causes a problem when the person is having a seizure. When someone with epilepsy is not having a seizure they will act normally and will not appear dreamy or switched off.
As an aneurysm is considered a blood clot and a brain aneurysm is classified as a TBI, they both can affect brain activity and neuronal activity in the body; therefore, aneurysms can directly cause seizures, and possibly lead to the disease known as epilepsy. However, a person can develop epilepsy at birth without having an aneurysm. Epilepsy has many causes besides an aneurysm, and many factors and causes, unfortunately, can result in a person being diagnosed with epilepsy and/or seizures.

Epilepsy has a wide variety of forms, causes and severity. As such there is no single thing that can cure all forms of epilepsy. Each case is taken on its own merits and treated differently. Something that works for one person may have no effect for someone else.
Epilepsy has many forms and causes, so there is no one thing that can be said to cure it. Epilepsy can be controlled by medication.
Epilepsy is not "spread". It is not contagious, it is not infectious. You cannot catch it from another person. It is a physical condition. So like you cannot catch a broken arm from someone, you cannot catch epilepsy from someone. There are many causes and forms of epilepsy. It is not a single condition, but a catch-all term for anyone that has recurring seizures. There are various reasons people have seizures. About the only way a person can get it from someone else is if a condition that causes seizures is passed on genetically. So people in the same family can sometimes get seizures, but as most cases of epilepsy are not genetic, then usually one person a family having seizures will not mean that others will too.
Not especially. Anyone can have it. About 1 in every 200 people do. Epilepsy is classified as someone having recurring seizures. Absolutely anyone can have a seizure in their lifetime and not ever have one again. There are many forms of epilepsy and many causes, making it possible to happen to anybody. It is because there are so many causes and forms that one overall label is used to cover them all, which is epilepsy.
Epilepsy has a wide range of causes. Some of them can be autoimmune, but certainly not all.
There are many causes of epilepsy. While it can be occasionally inherited, it is not really a genetic illness.
