I am sorry you and your baby are going through this. I don't know enough about neos to say if it is common, but I do know it is seriously considered by most to be hereditary. Did you get your baby from a breeder? If so, you should contact them and tell them what is happening, not only to find out if they have any knowledge of others in your guy's pedigree having had seizures, but to let him/her know that other dogs in your pup's litter and siblings from other litters are at risk. The next thing you need to do is start taking notes... write down when the seizures occur, how long they last, and what activity you observe during each specific seizure. From there, a vet appointment for bloodwork to rule out typical causes of seizures, and your vet will probably want to work with you on ruling out environmental causes as well. Usually, when you go to the vet for the first appointment, they will ask you to start keeping a record, with all the factors I mentioned previously, and the two of you will follow up from there. If you go to the first appointment already armed with a record in detail, it will speed up the process by several weeks/months, and get your baby on some meds that will help keep him seizure free hopefully for a long time. Good luck!
