The issue in this case is not uncommon. P is an adult who has an unresolved medical condition, in this case epilepsy. His primary carer, however well motivated, does not accept the diagnosis nor the treatment proposals. P may object to treatment (whether his own view or prompted by his carer). In order to determine what is in P's best interests, since he cannot decide for himself, it is necessary to observe him, and not to rely upon what is relayed about his condition by his carer. To that end, a period in hospital for assessment and treatment is necessary.
