I am totally unsure about this, because I've only ever really looked at the possibility of certain Autistic Spectrum Disorders with regards to myself, but now another facet of my behaviour has come to light.
Sometimes when lying in bed, I experience what I can only describe as a seizure, that lasts for the length of an electric shock, as though something in my brain short-circuited for a split second, causing my arms, legs, hearing and vision to twitch. This only happens when trying (really hard) to sleep, and only once or twice a night, and again, only every two or three nights (the nights I go to bed instead of staying on the computer non-stop).
I know it's not Tourette's Syndrome, because Tourette's requires motor and phonic tics, so I'm unsure as to what kind of Tic Disorder, if any, I may have. I could always just say it's Tic Disorder NOS, but that's very simplistic of me, as it may well be a Tic Disorder with defined diagnostic criteria.
Also, I don't know if this is related or not, but I sometimes also get nystagmus at night, and sometimes during the day. Have so for as long as I can remember, much like the "tics" themselves.
Can anyone shed any light, or provide links with info? It would be very much appreciated.
