BACKGROUND: Antipsychotics are frequently and often long-term used for challenging behaviour in persons with intellectual disability (ID), but the evidence base for this is meagre. As these agents may cause harmful side effects, discontinuation should be considered. Previous studies regarding discontinuation of long-term used antipsychotics mostly were uncontrolled and involved ...

The trigeminal circuit relays somatosensory input from the face into the central nervous system. In central nuclei, the spatial arrangement of neurons reproduces the physical distribution of peripheral receptors thus generating a somatotopic facial map during development. In mice, the ophthalmic, maxillary and mandibular trigeminal nerve branches maintain a somatotopic ...
