  • The routine diagnostic workup of M. pneumoniae encephalitis should therefore aim for the detection of M. pneumoniae antibodies in both CSF and serum, in addition to M. pneumoniae PCR in CSF.[journals.plos.org]
  • In addition to Patient 2 described in the case reports, two patients died, one of sudden cardiopulmonary arrest and the other of haemorrhagic infarction, a complication in the right cerebrum caused by candida meningitis.[doi.org]

  • However, absence of anti-GQ1b antibodies and normal MRI do not exclude the diagnosis, which remains based on clinical criteria and exclusion of other etiologies.[scholarbank.nus.edu.sg]
  • The etiology of this condition was speculated to be similar to that of Guillain-Barré syndrome because of evidence of prodromal upper respiratory infection, areflexia, and CSF albuminocytological dissociation ( Bickerstaff and Cloake 1951 ).[medlink.com]
  • Recent observations suggest that intrathecally detectable antibodies against the bacterium, which can serve to establish the etiology of encephalitis, may indeed mediate the disease.[journals.plos.org]

  • Serial electrophysiological studies allowed not only to understand the underlying pathophysiology and formulate a more correct prognosis but also to guide the treatment.[ncbi.nlm.nih.gov]
  • The pathophysiology of BBE is not proven; it is presumed that an autoimmune response has a key role. Encephalopathy-associated with autoimmune thyroid disease (EAATD) is another encephalopathy presumed to be related to autoimmune responses.[jksem.org]
  • Common seropositivity between these two conditions highlights their pathophysiological and clinical similarities.[practicalneurology.com]
  • However, it has some different pathophysiological mechanisms that are responsible of the clinical and laboratory and imaging studies differences.[new.medigraphic.com]
  • An anti-GQ1b antibody syndrome has been proposed to underlie the common pathophysiology for the three disorders; however, other studies have found a positive anti-GM1 instead of anti-GQ1b antibody.[digitalcommons.wayne.edu]
