Symptoms in a person with the lack of ADH.

Use as much biological terminology as you can please.

The hypothalamus produces a hormone (ADH) that is released by the posterior pituitary gland into the blood.

Brain damage can occur due to trauma to the head. Traumatic brain injury (TBI) can cause many and varied malfunctions of parts of the brain. One condition that can arise from TBI is a lack of ADH in the blood.

Suggest the symptoms you would expect in a person with a lack of ADH. Give a physiological explanation explanation for the symptoms. Key aspects are how ADH works on kidney structures to either absorb more or less water than say the symptoms (urine aspects).
