We have come up against this before via Twitter, and both times managed to get the article changed to properly reflect the different types of IH. If the little girl had Acute IH then yes it is life threatening as we know. This type is usually caused by severe head injury or intracranial bleed or stroke. The differences are very clear, so the parents have either misunderstood or dare I say, making more of it than they should be. Any credible journalist should check information thoroughly regarding health issues and conditions.
It is very annoying when this disease is misrepresented and the information incorrect.
