This quote is not from a published paper.
I had asked Dr. Bartzokis why risk of non-familial autism, schizophrenia, MS, and Alzheimer's risk increases with the age of the father at a person's birth.



"The issue is that the older man will have sperm that has undergone more divisions and therefore had more chances to have mutations.
The COMPLEXITY of the myelination process makes it more vulnerable to mutations. I am not talking of one specific mutation. Many things could MANIFEST in the myelination or myelin breakdown process because it is so vulnerable - something going slightly wrong will impact it while it will not impact bone growth or the heart. A good example is ApoE4 - whatever else it may affect, it manifests in the reduced capacity of myelin repair and earlier onset of AD."
