Conversion syndromes are frequent among medically unexplained somatic symptoms in neurology. A careful differential diagnosis must be carried out in a psychiatric consultation service. In a prospective study lasting for over four years 169 patients with pseudoneurological signs of conversion were included. From a clinical point of view the following conversion syndromes were presented: astasia/abasia: 27.2%, paresis/plegia: 24.3%, aphonia: 1.8%, hyp-/anaesthesia: 21.9%, blindness: 5.3%, non-epileptic seizures: 19.5%. According to the diagnostic criteria of DSM-III-R three subgroups were differentiated: conversion disorder (n = 132), somatisation disorder (n = 28), factitious disorder (n = 9). Intermittent courses of illness were prevailing in conversion disorder, whereas chronic courses predominated in the other two subgroups. High rates of psychiatric comorbidity were typical signs of somatisation disorder. Frequent autodestructive motives (suicidality, deliberate and covert self-harm, chronic pain, high rate of operations) in illness behaviour had to be registered in somatisation and factitious disorder. Both subgroups were characterised by frequent traumatic events during early development. Important socio-economic aspects of illness behaviour above all in somatisation and factitious disorder were underlined. The results are discussed in terms of psychiatric differential diagnosis and psychiatric comorbidity, psychodynamic evaluation, illness behaviour and therapeutic options in a C/L-service.

An 8-year-old male Tibetan Terrier showed prolonged astasia, complete paralysis, ticlike signs, and seizure and died 2 months after the onset of symptoms. Histopathologically, there was moderate to severe infiltration of pleomorphic histiocytic mononuclear cells bilaterally in the basiarachnoidal and ventricular areas of the brain. The spinal dura mater, arachnoidal space, and leptomeninges were also affected by infiltrative proliferation of these mononuclear cells. The infiltrating cells had the morphologic characteristics of histiocytes but exhibited moderate pleomorphism and atypia, with abundant mitotic figures. With immunohistochemistry and lectin histochemistry, most of the infiltrating cells were positive for lysozyme and lectin RCA-1 and negative for glial fibrillary acid protein, suggesting that they were of monocytic/histiocytic-origin. Positive proliferating cell nuclear antigen immunostaining demonstrated that most nuclei of the histiocytic cells were in the S phase of the cell cycle, consistent with a proliferating population of cells. Based on these findings, the case was diagnosed as diffuse leptomeningeal malignant histiocytosis.

It is difficult to differentiate astatic seizures among atonic, myoclonic and tonic seizures without the help of ictal polygraphic recordings. We described a girl with epilepsy presenting periodic astasia caused by epileptic spasms. Her seizures had occurred in clusters since 1-year and 7-month of age. Her interictal electroencephalogram (EEG) showed intermittent diffuse (poly) spike (s) and wave discharges, without a trace of hypsarrhythmia. She had a diagnosis of epilepsy with myoclonic-astatic seizures at a previous hospital, and her seizures had been resistant to multiple antiepileptic agents. After she was referred to our hospital, the ictal video-EEG recordings were made before and after ACTH administration, which revealed that her astatic seizures were epileptic spasms with presumed cortical origin. We should carefully evaluate the astatic seizures during early childhood which may be an atypical presentation of epileptic spasms.

Temporal lobectomy can be complicated by somatoform disorders, psychiatric illnesses and non-epileptic psychogenic seizures. We report a woman who developed astasia-abasia and psychogenic tremor following temporal lobectomy for refractory epilepsy. To our knowledge, this type of conversion reaction following temporal lobectomy has not been previously reported.
