Why is ADH not increased

why is ADH not increased in cerebral salt wasting syndrome despite low sodium, is there any connection of ADH to RAA system or ANP?

Hypovolemia and sodium loss that occurs with Cerebral Salt Wasting can lead to supranormal ADH release. ADH and the RAAS work together in response to low blood volume/ blood pressure and low sodium to bring up volume and BP.

ANP is released in response to high volume and atrial distention, and acts in an opposite manner to aldosterone. Thank you.
