<unk><unk><unk>  seizures of<unk>  (MMPSI) is a rare epileptic syndrome that onsets before 6 months of age, commonly in the first few weeks of life. Once seizures start, the site of seizure activity repeatedly migrates from one area of the brain to another, with few periods of remission in between. These seizures are 'focal' (updated term for<unk> '), meaning they do not affect both sides of the brain at the same time. These continuous seizures cause damage to the brain, hence the descriptor<unk> .' The cause often is not known, although mutation of the KCNT1 gene has shown to be associated. Another gene implicated is PLCB1. MMPSI is diagnosed based on signs, symptoms, and electroencephalogram (EEG) findings. As of 2012, 80 cases have been reported. It was first described in 1995 by Copolla et al.
