Patients with this condition tend to be highly anxious about their symptoms, even in the face of evidence that their condition is not medically serious. In the draft of the upcoming Diagnostic and Statistical Manual of Mental Disorders (DSM-V), this condition...

BACKGROUND Psychological models of conversion disorder (CD) traditionally assume that psychosocial stressors are identifiable around symptom onset. In the face of limited supportive evidence such models are being challenged. METHOD Forty-three motor CD patients, 28 depression patients and 28 healthy controls were assessed using the Life Events and Difficulties Schedule in the year before symp...

Combined spinal epidural (CSE) can provide excellent labor analgesia. Subdural block is also a potential but rare complication of attempted epidural placement during a CSE procedure, which may present as a block that is usually patchy in nature, with a component of sensory and/or motor deficit and a variable duration of action. In addition, a conversion disorder or a functional neurological dis...

Statistical mechanical modeling is developed to describe a catalytic conversion reaction A→B^{c} or B^{t} with concentration-dependent selectivity of the products, B^{c} or B^{t}, where reaction occurs inside catalytic particles traversed by narrow linear nanopores. The associated restricted diffusive transport, which in the extreme case is described by single-file diffusion, naturally induces ...
