Improvement of functional paralysis following unexpected comatose states.
Instances of recovery from a functional neurological disorder (FND) can shine a light on the nature of the condition and its potential treatment. Unexpected recovery of FND symptoms can occur after a comatose state or an anaesthetic, or after various other scenarios. Two illustrative cases exemplify the phenomenon. A 59-year-old man had an 8-year history of functional paraparesis that had developed subacutely following a car crash. The paralysis recovered dramatically after an episode of medically induced coma, administered because of SARS-CoV-2 acute respiratory distress. A 40-year-old woman had complete recovery of FND-related arm paralysis and associated chronic pain after a deliberate overdose that led to a comatose state necessitating a brief period of ventilation. We compare these with similar recoveries in other scenarios, such as following hypnosis or extreme external stress. We discuss the potential mechanisms for recovery and the implications for FND treatment.
期刊介绍：
The essential point of Practical Neurology is that it is practical in the sense of being useful for everyone who sees neurological patients and who wants to keep up to date, and safe, in managing them. In other words this is a journal for jobbing neurologists - which most of us are for at least part of our time - who plough through the tension headaches and funny turns week in and week out. Primary research literature potentially relevant to routine clinical practice is far too much for any neurologist to read, let alone understand, critically appraise and assimilate. Therefore, if research is to influence clinical practice appropriately and quickly it has to be digested and provided to neurologists in an informative and convenient way.
