R,

This notion is often presented in autism. Perhaps in a few cases,
demyelinization may be a primary cause. However, in far more cases, the
underlying lesion that leads to demyelinizing processes may be more
important. These lesions may be viral and/or bacterial and/or fungal
and/or may be due to neuronal death from virtually any kind of prolonged
cerebral or peripheral edema. 

In recent days I've had personal communications from two researchers
prominent in immuno/autism research (Singh & Gupta). Each person agrees
that elevated antibodies to neurofilament protein and to myelin basic
protein may reflect peripheral and/or cns sources! 

In my opinion, the fact of demyelinization (eg, from antibodies levels)
should not preclude consideration of "what killed the neurons?", because
killing neurons may be the initiating event that led to enough "bits and
chunks" of neurons, that led to neuron-pieces as epitopes, that led to an
autoimmune reaction...

Writing hurridly, can'ya tell?

Teresa
