'Hysterical' Motor Symptoms Explained?

[Cheshire]

Abnormally high levels of limbic glutamate may be at the root of unexplained functional motor symptoms (FMS) that previously have been attributed to "hysteria."

Researches used magnetic resonance spectroscopy (MRS) to evaluate N-acetylaspartate (NAA) levels; myo-inositol (MI) levels; choline (Cho) levels; the sum of glutamate and glutamine (Glx); and creatine (Cr) content in two brain regions of patients with FMS and compared those results to results obtained from healthy control persons.

It's a very, very small sample, not replicated and so on. But it is interesting to see some biomedical research happening in that field.

Hasn't glutamate been suggested before?

Doubt it. You see this sort of nonspecific result in all kinds of brain problems.
