The paper updates the word ”psychogenic”; suggests a pathophysiologic reading of the psychogenic contribute to CPP, via the stress-induced corticotropin-releasing factor (CRF) signaling pathways, and differentiates predisposing, precipitating and maintaining factors; summarizes the pertinent evidence; focuses on the differential diagnosis between prominent “psychogenic” vs somatic etiology of C...

Background: Differentiating psychogenic parkinsonism from neurodegenerative Parkinson’s disease (PD) with psychogenic features is a diagnostic challenge. Case report: We report a detailed longitudinal clinical description of three cases presenting with suspected psychogenic parkinsonism. Dopamine transporter single-photon emission computed tomography (DAT-SPECT) was used as a supplemental diagn...

Background: Lichen simplex chronicus (LSC), nodular prurigo (NP), and neurotic excoriation (NE) are considered as psychogenic pruritus disorders. Atopic dermatitis (AD) is also classified by some as a psychocutaneous disorder to point out the influence of psychologic factors in its recurrence, persistence and precipitation. AD and psychogenic pruritus share many common features including immuno...

Despite significant advances in epileptology, the differential diagnosis of epileptic and pseudoepileptic seizures continues to be a considerable challenge. The problem becomes even more complicated when epileptic and psychogenic pseudoepileptic seizures coexist in the same patient. Appropriate psychological measures may be helpful in the diagnosis and may improve knowledge about aetiological f...

The facial phenotype of psychogenic movement disorders has not been fully characterized. Seven tertiary-referral movement disorders centers using a standardized data collection on a computerized database performed a retrospective chart review of psychogenic movement disorders involving the face. Patients with organic forms of facial dystonia or any medical or neurological disorder known to affe...
