Dear Researchers, 

I am in the process of writing a proposal and I am looking for an answer for this question in order to complete my research plan. "What is the morphological and the biochemical characterisation of different tau aggregates among Alzheimer disease patients".

I've already looked deeply in the literature but till now didn't get a clear study that shows the different tau aggregates exhibited among different cases of AD. 

I am looking forward to hearing from you,

Regards, 

Mohamed
