Nervous shock is the term used to describe psychiatric injury or harm. This harm must be medically recognised, and it does not include human emotion such as grief. For example, in Hinz v Berry (1970) morbid depression was held to be psychiatric harm, as opposed to grief or sorrow. In Reilly v Merseyside Regional Health Authority (1994), the claimant suffered difficulty in breathing, dizziness and claustrophobia, insomnia and nightmares. These are not recognised are psychiatric harm. However, the case of Vernon v Bosley (No.1) (1996) held that an abnormal degree of grief could lead to psychiatric harm.
