BACKGROUND Patients with psychogenic amnesia generally suffer from episodic memory deficits associated with an impairment of self-identity. While the first is generally attributed to limbic dysfunction, the latter might be related to posterior parietal cortex. METHODS AND RESULTS In a patient with acute repetitive psychogenic amnesia, three different functional investigations (fMRI, electrica...

The various reported psychogenic dyskinesias include tremor, dystonia, myoclonus, gait disorder, Parkinsonism, tics, and chorea. It is not easy to diagnose psychogenic movement disorders, especially in patients with underlying organic disease. We describe three patients with balance and/or posture abnormalities that occur when they stand up, start to move, or halt from walking, although their g...

Psychogenic (nonepileptic) seizures are among the most common and serious of all psychogenic neurological disorders. They account for approximately 20% of all intractable seizure disorders referred to comprehensive epilepsy centers and present with a reported annual incidence of approximately 4% that of true epilepsy. These events are serious and disabling. Indeed, compared with patients with t...

As the field of movement disorders has developed and matured over the past 25 years, psychogenic movement disorders have become increasingly recognized in subspecialty clinics. The diagnosis can be challenging and should be based on positive features rather than a purely exclusionary approach. The clinical phenotype can be quite varied, although certain categories of abnormal movement are more ...

Psychogenic movement disorders are heterogeneous and diagnostically challenging. Despite the growing literature on adult forms, clinical features in children have received relatively little attention. We retrospectively reviewed medical records and video of patients <18 years diagnosed with a psychogenic movement disorder at our institute between 2007 and 2010. We identified 14 patients (6 male...

Introduction: Psychogenic anejaculation is a rare cause of male infertility. In this type of anejaculation, the patient cannot ejaculate while awake. Most cases of this disorder were reported in Jewish communities. In the present report, we describe the successful achievement of pregnancy in two Muslim men with situational psychogenic anejaculation. The treatment involved the simplest approach ...

a twelve-year-old girl with disseminated tuberculosis was complicated by psychogenic vomiting and multiple drugs’ adverse effects. she was admitted to our hospital, complaining of fever, cough and abdominal pain. diagnosis of tb was obtained by abdominal ct-scan and open liver biopsy. during the anti-tb treatment, hepatitis, hemolytic anemia and pancreatitis occurred due to some drugs' side eff...

To the Editor: A number of epidemiologic studies have confirmed the importance of postnatal insults as a cause of epilepsy.1 Neuroimaging has been an increasingly important diagnostic tool, and it has been stated that the demonstration of “epileptogenic lesions” strongly supports the diagnosis of epilepsy in these individuals.2 The article by Benbadis et al. is a timely reminder of the pitfalls...

INTRODUCTION Henoch-Schönlein purpura is an immunoglobulin A-mediated, small vascular inflammatory disease that can be associated with palpable purpura, arthralgia, abdominal pain, or nephritis. The presence of purpura facilitates the diagnosis of Henoch-Schönlein purpura at the onset of associated symptoms, whereas the absence of purpura makes the diagnosis challenging. It is important to diag...

Henoch-Schönlein purpura is the most common systemic vasculitis of childhood. In the majority of children, the outcome of Henoch-Schönlein purpura is excellent with spontaneous resolution of symptoms and signs. However, a small subset of patients will develop long-term sequelae in the form of chronic kidney disease. While the clinical presentation and diagnosis of Henoch-Schönlein purpura is st...
