Ever since I was born, I've had these "laughing fits" every night before I fell asleep. As I got older, they would occur during the day if I were tired or stressed. It has happened for several years into my early adulthood, and nothing has come of it, so my family took it as just something I did. Lately, perhaps due to stress or some other unknown factor, they have been increasing in frequency and strength. Worried that something may be medically wrong, I went to have tests done to discover what is causing these seizures. I have seizure brain activity but nothing showing on the MRI (such as a tumor). We have thought it to be gelastic seizures but are not sure because it seems like there is no one out there that has it... especially as an adult. I can't really put into words what my laughing spells are like.. I get this odd rushing of adrenaline a few seconds before they come and then the spell begins. It's an intense adrenaline rush and seems like fireworks going off in my neurons (as silly as that sounds, it is the closest I can manage to describing the intensity). The laughing will subside after about 10 seconds. Sometimes I am drained afterwards or fired up and angry for nothing. Regardless, these seizures are something that I have to deal with and hide from my friends. Because of its variety, it is hard to find support. If anyone knows what I have, please let me know.
