Luther is presenting symptoms of delirium, which is a sudden and fluctuating disturbance in consciousness and cognition that can occur as a result of physical illness or injury, including head trauma. Neurocognitive disorder and depression typically have a more gradual onset and do not typically present with sudden confusion and disorientation like Luther is experiencing. Amnesia may be a component of delirium but it does not fully capture the range of symptoms Luther is exhibiting.
