“…Some authors admit that COVID-19 infections may contribute to accelerating the development of or altering the course of pre-existing neuropsychiatric disorders which is in line with recent literature ( Quincozes-Santos et al, 2021 ). Additionally, as will be described below, NMDA receptor antagonists, such as memantine or amantadine, and benzodiazepines can be used as a treatment option for catatonia ( Jaimes-Albornoz et al, 2022 , Carroll et al, 2005 ), which might suggest that the abrupt suspension of these drugs, days before the admission to the inpatient unit, may also have favored the worsened of catatonia in our patient. This hypothesis is in line with the literature which suggest that abrupt discontinuation of certain drugs, namely benzodiazepines and NMDA receptor antagonists, may contribute to catatonia onset or worsening.…”
