Three inflammatory neuropathies:
-Chronic Inflammatory Dimylenating Polyneuropathy (CIDP) – 58%
– IgM paraproteinaemic neuropathy (IgMPN) – common
-[Multifocal Motor Neuropathy with conduction block] – 56% –
all were being given regular immunoglobulin infusions
medications for tremors did not work; 5 found benefit from immunoglobulin infusions
mean frequency was 6 hertz
10/27 cases precipitating event evident
Comment – have seen it; nice to know it is there.
