Psychogenic nonepileptic seizures (PNES) are relatively common occurrences in epilepsy centers [1]. These seizures consist of paroxysmal changes in responsiveness, movements, or behavior that superficially resemble epileptic seizures, but lack a neurobiological origin as in epileptic seizures and are not associated with electrophysiological epileptic changes [1]. It is clear that PNES lack a ne...

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...

Premature ejaculation has generally been considered a psychosexual disorder with psychogenic aetiology. Although still mainly treated by behavioural therapy, in recent years double-blind studies have indicated the beneficial effects of some of the serotonergic antidepressants (SSRIs) in delaying ejaculation. We describe here the neurophysiology and the peripheral neuroanatomy of ejaculation and...

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...

Epilepsy is a chronic medical condition which is disabling to both patients and caregivers. The differential diagnosis of epilepsy includes psychogenic nonepileptic spells or "pseudoseizures." Epilepsy is due to abnormal electrical activity in the brain, and pseudoseizure is a form of conversion disorder. The brain waves remain normal in pseudoseizures. The problem arises when a patient with si...

An 11-year-old girl was transferred to the Universidad de Chile Clinical Hospital after 2.5 months of persistent and unresponsive treatment for coughlike spasms. On arrival, the frequency of symptoms was 1 cough every 4 s, which disappeared during sleep. A multidisciplinary examination excluded allergic, viral, respiratory, epileptic, and other more usual causes of similar conditions. Two diagn...

CASE REPORT We report a detailed longitudinal clinical description of three cases presenting with suspected psychogenic parkinsonism.

Clinical signs are critical in ascertaining the functional nature of a gait disorder. Four signs of gait impairment have been documented in the course of examining patients with clinically definite functional (psychogenic) movement disorders: "huffing and puffing" during standing and walking, manipulation-resistance dorsiflexion of the first toe, fixed plantar flexion and inversion, and marked ...

A 48-year-old male was diagnosed with both drug resistant epilepsy and psychogenic nonepileptic seizures. Both diagnoses were confirmed by video-EEG monitoring. His epileptic seizures were a consequence of right mesial temporal sclerosis. He was diagnosed by a psychiatrist to have depression and posttraumatic stress disorder (PTSD). Following a right anterior temporal resection he became seizur...
