EEG in subacute sclerosing pan encephalitis (SSPE)

SSPE is a chronic progressive neurodegenerative disorder due to persistent infection by the measles virus.It occurs in children and young adults. It manifests with progressive cognitive decline, myoclonic jerks and ends in a persistent vegetative state.
The EEG is very characteristic with the well known Rademecker complex. This consists of high voltage 300 to 1500uv repetitive polyphasic sharp and slow waves lasting 0.5 to 2 secs and occuring regularly at every 4-15 secs. As the disease progresses the interburst periods may decrease.

  1. You really make it seem so simple with your presentation but I find that topic to be really something that I think I would under no circumstances undertsand. It seems too complicated and also really broad for me. I am looking forward for your next post, I will try to get the hang of it!
