Anxiety states sometimes lead to hyperventilation (HV) which may, in turn, give rise to a variety of physical symptoms. One way in which HV may present is with unilateral somatosensory symptoms, often left-sided. We report nine such cases. The mechanisms of lateralisation was examined using EEG and bilateral somatosensory evoked potentials which were(More)
Compared with other psychiatric disorders, diagnosis of factitious disorders is rare, with identification largely dependent on the systematic collection of relevant information, including a detailed chronology and scrutiny of the patient's medical record. Management of such disorders ideally requires a team-based approach and close involvement of the(More)
In this paper we question the validity of factitious disorder as a meaningful psychiatric diagnosis. When the diagnosis is used there is often the assumption that the person engaging in the 'deception' is not lying in the traditional sense of being deliberately misleading. Moreover, little is known about the aetiology or psychopathology underlying(More)
The hyperventilation provocation test (HPT) has been widely used for reproducing symptoms of panics. It is assumed that subjects experience similar symptoms on consecutive occasions of hyperventilation. Fourteen subjects with a history of panics and fourteen without such a history underwent the HPT on two occasions one week apart. In the group of 28(More)

We review the literature on the relationship between somatoform disorders and personality disorders, which reveals that approximately two in three patients with a somatoform disorder meet criteria for a personality disorder. We suggest that the most clinically salient problems presented by patients with somatoform disorders reflect dysfunctions of(More)
BACKGROUND Among older people, somatization has been reported to be common and to be predictive of high attendance in primary care. Its relationship with quality of life among older people has not been investigated. OBJECTIVES The objective was to establish whether, among older primary care attenders, somatized symptoms are independently associated with(More)
OBJECTIVE We describe a case of psychogenic malignant catatonia resulting in permanent cognitive impairment. BACKGROUND Catatonia is a neuropsychiatric syndrome characterized by catalepsy, negativism, mutism, muscular rigidity, and mannerisms, often accompanied by autonomic instability and fever. Little is known about the long-term cognitive consequences(More)
Fabricated or induced illness (previously known as Munchausen syndrome by proxy) takes place when a caregiver elicits health care on the child's behalf in an unjustified way. Although the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders specifies deception as a perpetrator characteristic, a far wider range is encountered clinically(More)
