Hemispheric differences for visual P3 amplitude in patients with schizophrenia

Objective:
While reduced amplitude of visual P3 event related potential has been reported in patients with schizophrenia, little is known about visual P3 asymmetry. The present study aimed to investigate the presence and pattern of lateralization of the P3 component in a group of patients with schizophrenia.
Methods:
ERPs were recorded in 25 patients and 26 control individuals, using a simple visual oddball discrimination task.

Four clinical cases of recurrent surgery addiction (polyoperes): diagnostic classification in the DSM-IV-TR vs DSM-5

The article presents four clinical cases of patients with the common history of recurrent surgery. These conditions are interesting first of all for general medicine and surgery, apart from psychiatry. Indeed, patients with these characteristics are almost invariably subjected to psychiatric evaluation by internal doctors and surgeons and this is evident in our case reports, despite the rarity of the phenomenon in latest decades aside from plastic surgery. The first aim of the study is to compare diagnostic classifications between DSM-IV-TR and DSM-5 in reference to the case reports of recurrent surgery in order to observe the changes occurring in the diagnostic criteria and classification and the different attitude of the two manuals towards these disorders. The second endpoint is to describe the common features and the differences between the cases that could motivate a different prognostic evolution to raise a hypothesis that could be a starting point for further research.

Mental health organizations and the ostrich policy

Image
Psychogenic nonepileptic seizures (PNES) and psychogenic symptoms in general are common. However they may be termed or classified, they constitute an important part of psychiatry and psychology. The largest professional mental health organizations (American Psychiatric Association and American Psychological Association [APAs]) both have abundant patient education material, but curiously have no information on this entire category of disorders. It is surprising that, with so many members for so many years, this ‘omission’ seems to have gone unnoticed.

In search of the pathophysiology and prevention of schizophrenia

There was a particular poignancy and tragedy associated with schizophrenia that involved children growing up, maturing during adolescence … and then all of a sudden becoming afflicted with this disturbance in their mental functioning.
