Good Erythrina Mulungu extract, is worth considering. And harm reductive.
DSM-5 describes Delirium as what dr's here call a Delier. Which is probably a Dutch word meaning the same. The symptoms overlap.
Sorry for getting obsessed with that term, just when I had a non-concious Ictal Psychosis (post, during and after), which is a feature of seizure I was having.
But when medical staff has no clue what is happening to you. They really hurt me during my beserk fases, causing lasting damage.
And then later you later read in your file they considering it a Delirium/ Delier. And call for a psychiater which arrive's 1 1/2 later to administer some Diazepam and Haldol.
