please explain your answer.
hint.... pituitary stalk
The posterior pituitary (neurohypophysis) contains the nerve terminals of neurons with the cell bodies located in the hypothalamus. The axons of these nerves, i.e. the connection between the neurohypophysis and the hypothalamus is the pituitary stalk. Therefore, if this stalk is damaged, then you would expect an interruption in travel of ADH from the hypothalamus to the posterior pituitary, resulting in central diabetes insipidus.
I am not sure if the damage would be permanent, I would guess yes?
