Sudden vision loss, weakness in one or both eyes, loss of sensation, loss of bladder fn
Neuromyelitis Optica (Devic’s Disease)

Treat neuromyelitis Optica (Devic’s disease) with
Rituxumab
Binds to CD20 (which is widely expressed on B cells) and induces B cells to enter apoptosis

Heterogenous group of genetically distinct disorders with similar presentations
CMT
Type 1 CMT
Demyelinating

Type 1 CMT
Onion bulbing effect from demyelination and remyelination
Type 1 CMT
Presents in teenage years or early adulthood. Distal muscle wasting and weakness. Affects legs first
CMT type 1
Pts have very high arches and hammer toes

CMT 3
Decreased velocity and increased latency
Demylination
Decreased amplitude (wire is damaged)
