The clinical manifestation is similar to neurogenic<unk><unk> , presenting with polydipsia (excessive thirst) and polyuria (excretion of a large amount of dilute urine). Dehydration is common, and incontinence can occur secondary to chronic bladder distension. On investigation, there will be an increased plasma osmolarity and decreased urine osmolarity. As pituitary function is normal, antidiuretic hormone levels are likely to be abnormal or raised. Polyuria will continue as long as the patient is able to drink. If the patient is unable to drink and is still unable to concentrate the urine, then hypernatremia will ensue with its neurologic symptoms.
