Neuromuscular junction disorders: mimics and chameleons.
Neuromuscular junction (NMJ) disorders represent a heterogenous group of acquired and congenital disorders that present in variable and distinctive ways. The diagnosis is typically reached through a combination of clinical, serological, pharmacological and electrophysiological evaluation. While the diagnosis can be fairly straightforward in some cases, the overlap with other neurological disorders can make diagnosis challenging, particularly in pure ocular presentations and in seronegative patients. The over-reliance on serological tests and electrophysiological evaluation in isolation can lead to misdiagnosis. In this article, we provide an overview of the NMJ disorders, discuss red flags for the key differential diagnoses (mimics) and report the atypical ways in which NMJ disorders may present (chameleons).
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.
