It seems that he is having small (i think they are called Catonic Seizures) at nightime. He will lose mobility in his limbs for a period of 5 to 10 mins and his speech gets slurred. Any help would be appreciated.
That sounds more like Sleep Paralysis than Catatonia. It normally lasts anywhere from 30 seconds to 3 minutes, although in rare cases it can last as much as 10 minutes. It's often associated with "sleep terrors".

Sleep paralysis is experienced by nearly everyone at some time or another, but is experienced more frequently by people with narcolepsy, sleep deprivation and/or extreme stress. If he was actually in a catatonic state then that would indicate schizophrenia.
