Vestibular dysfunction is a significant differential diagnosis in patients who have unexpected falls without: loss of consciousness, paresis, sensory loss, or cerebellar deficit. Either peripheral or central vestibular disorders cause postural instability with preferred directions of falling, some of which can be attributed to either the particular plane of the affected semicircular canal or a central pathway mediating the 3-dimensional vestibulo-ocular reflex in yaw, pitch, and roll. Ipsiversive falls occur in vestibular neuritis or in Wallenberg's syndrome--where they are known as lateropulsion. Contraversive falls are typical for the otolith Tullio phenomenon, vestibular epilepsy, and thalamic astasia. Predominant fore-aft instability is observed in bilateral vestibulopathy, benign paroxysmal positioning vertigo, as well as in downbeat or upbeat nystagmus syndrome. Falls can be diagonally forward (or backward) and toward or away from the side of the lesion, depending on the site of the lesion (the ocular tilt reaction is ipsiversive in medullary lesions, but contraversive in mesencephalic lesions) and on whether vestibular structures are excited or inhibited.

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.
