Association such as this are interesting, but I would prefer to understand the causative effects better. Why would a lower LDL be associated with Parkinsons. Does this effect the Swan sheath somehow? Is Cholesterol a substrate in the production of certain nuerotransmitters? If so, does the reduction from a statin effect the production of the transmitter?
Why would low cholesterol levels (is this total C or a specific fraction thereof?) be associated with depression? Could it be that the chemical changes associated with depression have caused a lowering in the production of Cholesterol?
These association don't explain a lot.
