Types of Seizures

There are 4 groups of types of seizures I was able to find, they are (1) Generalized Seizures, (2) Partial Seizures, (3) Nonepileptic Seizures, and (4) Status Epilepticus

Generalized Seizures and Partial Seizures are different because in a generalized seizure, both hemispheres of the brain is affected, and in a partial seizure, only one hemisphere (or side) of the brain is involved, although a partial seizure can spread to the other hemisphere of the brain and become a generalized seizure.

Now, to break it down even more, there are also 4 different types of generalized seizures! The first kind is the most common as well as the most dramatic. This is probably what most people think of when they hear the term "seizure". It is called the generalized tonic clonic seizure, better known as the gran mal seizure. Here, the patient loses consciousness, and usually collapses, then the body stiffens for about 30-60 seconds (tonic phase), then the body starts to jerk violently for about 30-60 seconds (clonic phase). Finally, after all that the patient falls into a deep sleep. (the postical or "after seizure" phase).
The next kind of generalized seizure are called Myoclonic Seizures. Here, there are rapid brief contractions of bodily muscles, these contractions are sometimes confused with fits of clumsiness. These usually occur on both sides of the body. A person having this kind of seizure may experience unintentional dropping or throwing of objects they are holding. 
Next, are seizures called Atonic Seizures. These seizures produce abrupt loss of muscle tone causing head drops, loss of posture, or sudden collapse and frequent falls.
Next are called Absence Seizures. When someone is experiencing one of these, there is a loss of awareness, and the person will "stare off into space". These begin and end quickly, sometimes with no warning or lasting after effect. Sometimes there is no memory of the occurrence either. They are more common in children than adults, and they can have up to 100 episodes a day or more. 
Lastly are seizures called Infantile Spasms. These are classified as quick sudden movement. They occur in children between ages 3months - 2years.

Partial Seizures are broken down into two categories. The first category is called simple partial seizures. When these happen, the person retains most of their awareness, memory and consciousness. They can experience jerky muscles and spasms, as well as unusual emotions or sometimes memory disturbances. They can also have some unusual experiences effecting the senses. The second category is called complex partial seizures. When these occur, awareness, memory and consciousness are all impaired either all together or one or two. Here, they may experience body spasms such as lip smacking, fidgeting, as well as uncoordinated movements. Partial seizures don't last long, and they end naturally, you cannot stop them, all that can be done is wait for them to come out of it.

The third group of seizures are known as Nonepileptic Seizures. These are behaviors that look like an epileptic seizure, but it is an isolated random occurrence, not caused by abnormal electrical activity in the brain. Lastly, there is a condition called Status Epilepticus. This term literally means a continuous state of seizure. This is basically a prolonged seizure, or a continued series of multiple seizures.

Sometimes when a person is about to have a seizure, they can experience a type of warning sign also known as an aura. An aura can be any hallucinations of sounds, sights or colors, smells, or random thoughts. Also, some physical feelings have been reported, such as headaches, and nausea. as well as weird unusual or inappropriate emotions are common too.
