In severe cases, SIADH can cause confusion, seizures, and coma. Treatment usually begins with limiting fluid intake to prevent further buildup. Additional treatment will depend on the cause. Another name for the syndrome is “ectopic ADH secretion.”

Is SIADH permanent?

The syndrome of inappropriate antidiuretic hormone secretion (SIADH) can occur following traumatic brain injury (TBI), but is usually transient. There are very few case reports describing chronic SIADH and all resolved within 12 months, except for one case complicated by meningo-encephalitis.

• Headaches.
• Depression.
• Memory problems.
