Different causes of dizziness or vertigo can only be recognized by thorough anamnestic explorations. Following a classification in vestibular and nonvestibular causes for vertigo, a further differentiation is possible by defining different characteristic qualities of the symptoms involved. In addition to the classical vestibular forms of vertigo seen, dizziness currently results from drug overdosages, hypertension, polyneuropathy and--less commonly, but equally important--brief epileptic seizures. Psychosomatic and neurotic symptoms may also lead to unsteady gait, dizziness or vertigo, all of which are distinguished only with difficulty by the patient.

Out of 66 patients who were diagnosed as suffering from polymyalgia rheumatica (PMR; n = 40), temporal arteritis (AT; n = 14) or both (n = 12) in a 6.5 year period (incidence 3.4/100,000 per year), 9 died and 49 were followed up for an average period of 28 months. Exacerbations of the illness (n = 24) and complications in the course (n = 32) were more frequent with an initial ESR greater than 90 mm/h. Postural vertigo (n = 11), amaurosis fugax (n = 11) and polyneuropathy (n = 8) were the most frequent neurological complications. Persisting unilateral blindness and aromatic anosmia developed in 2 patients each. Complications were significantly more frequent in patients with initial symptoms of AT (chi 2 P less than 0.001). CRP-levels correlated better with persisting symptoms in the course than did the ESR. Recurrences after treatment were significantly more frequent when the length of corticosteroid-therapy was less than 20 months (chi 2 P less than 0.009). On follow up there were normal values for neopterin, tumour necrosis factor and antibodies against Borrelia burgdorferi.

In the group of 37 patients with chronic carbon disulphide (CS2) intoxication manifested by encephalopathy, polyneuropathy or psycho-organic syndrome and complaining for vertigo, a statokinesiometric test was performed with open and closed eyes, and with visual stimulation. Basic test parameters of stabilograms and statokinesiograms were compared with standard values of the control group. Results of the test were additionally verified by electronystagmography with the recording of spontaneous, positional, optokinetic and post-rotatory nystagmus as well as the eye-tracking test. The statokinesiometry revealed postural stability disorder in 72.9% of patients. Balance disorders detected by means of this test showed high compatibility with results of electronystagmography which confirmed damage of the central part of vestibular system due to CS2 intoxication.

The study comprised 48 workers employed at production of organophosphorous pesticides. In the clinical picture the subjective symptoms complex was predominant including: pains, vertigo, feeling of fatigue after work, difficulties with attention concentration and memorizing, paresthesia. The objective symptoms in the nervous system occurred in the form of polyneuropathy (22.9%). Among abnormal EEG records, the changes of the generalized character were the most prevalent (22.9%).

Neurological signs and symptoms were recorded from 156 air and saturation divers and 100 controls. Fifty one (33%) of the divers had had symptoms from the central nervous system during decompression. Also, 22 (14%) had been unconscious while diving. In total 79 (51%) had had decompression sickness (DCS). Twelve (8%) of the divers and no controls had had specific neurological symptoms (vision disturbances, vertigo, reduced skin sensitivity) in non-diving situations, and six (4%) of the divers (no controls) had had episodes of cerebral dysfunction (seizures, transient cerebral ischaemia, transient amnesia). The divers had significantly more general symptoms from the nervous system and more abnormal neurological findings than the controls. The most prominent symptoms were difficulties in concentration and problems with long and short term memory. The most prominent abnormal findings in the divers were compatible with dysfunction in the distal spinal cord or nerve roots, and polyneuropathy. The general neurological symptoms and findings were independently significantly correlated with diving exposure, prevalence of DCS, and age.

A literature review and an own case observation of neurological and psychiatrical disturbances in vinyl chloride disease are presented. In acute vinyl chloride intoxication, patients complain of vertigo, nausea and headache. At higher concentrations, vinyl chloride exerts a narcotic effect. In patients with chronic occupational exposure, neurological disturbances include sensory-motor polyneuropathy, trigeminal sensory neuropathy, slight pyramidal signs and cerebellar and extrapyramidal motor disorders. Psychiatric disturbances present as neurasthenic or depressive syndromes. Sleep disorders and disorders of sexual functions are frequently encountered. Pathological EEG alterations can be found in a high proportion of patients. The long term course and prognosis of the neurological and psychiatrical disorders in vinyl chloride disease are obscure. In an own case, a slight sensory polyneuropathy, bilateral hyposmia, a marked neurasthenic syndrome, typical EEG changes and computed tomography signs of cerebral atrophy were found in a 56-years-old patient as late as 16 years after the exposure to vinyl chloride.

Neurological findings were examined in 186 forestry workers with a mean exposure to chain saw vibration of 16.6 hours. The prevalence of active vibration induced white fingers was 5%, parethaesias of the hands 53%, and muscle weakness 13%. Clinical polyneuropathy was observed in 16 forestry workers in the hands (7.5%) which did not correlate with alcohol consumption. Seventy nine forestry workers of the total population were selected for electromyographic examination. Generalised EMG based polyneuropathy in the hands was observed in only two of the 79 forestry workers (2.5%). The carpal tunnel syndrome was found in 20 of the 79 forestry workers (26%). Headache and vertigo were not linked with exposure to vibration in forestry and a significant part of the numbness reported may be due to the carpal tunnel syndrome. Sensorimotor polyneuropathy is rare among forestry workers. The rise in the vibration detection thresholds was linked to the carpal tunnel syndrome.

We studied the frequency of oligoclonal immunoglobulin G bands in the cerebrospinal fluid (CSF) of patients with various neurological diseases. We used a micromethod employing sodium dodecyl sulfate polyacrylamide gel electrophoresis that required only 50 microliters of unconcentrated CSF. Oligoclonal bands were detected in the CSF of 95% of the patients with multiple sclerosis, 90% with subacute sclerosing panencephalitis, and 100% with herpes simplex encephalitis, but less frequently in other central nervous system infections. No oligoclonal bands were detected in the CSF of patients with Parkinson, Huntington, Creutzfeldt-Jakob, or herniated disc diseases. Bands were detected in some patients with Alzheimer disease, cerebrovascular accident, idiopathic vertigo, idiopathic seizures, amyotrophic lateral sclerosis, polyneuropathy, and central nervous system glioma. Patients with other conditions infrequently had positive bands. The determination of oligoclonal bands is a useful aid in the diagnosis of multiple sclerosis, subacute sclerosing panencephalitis, and herpes simplex encephalitis. The presence of oligoclonal bands indicates an immunological response but is not diagnostic for a particular condition.

Agarose isoelectric focusing was used to demonstrate oligoclonal bands in cerebrospinal fluid (CSF) and serum from 998 consecutive neurological patients. Compared with agarose electrophoresis, agarose isoelectric focusing was slightly more sensitive, showing more (and more easily discernible) oligoclonal bands. Agarose isoelectric focusing, which has good reproducibility, revealed oligoclonal bands in CSF in 95% of 43 patients with multiple sclerosis, 44% of 39 with aseptic meningoencephalitis, and 14% of 906 with other neurological diseases. Interestingly, oligoclonal bands were found in CSF from 12% of 162 patients with acute cerebral infarction and 23% of 53 with polyneuropathy, and also in 29% of 17 with dementia, while only 4% of 206 patients with headache, vertigo, or psychoneurosis had this CSF abnormality. We recommend this procedure for the routine examination of paired CSF and serum specimens for the presence of oligoclonal bands.

A 45-year-old male patient presented with cold-induced generalized livedo reticularis, repeated acral ulcerations and purpura, Raynaud's phenomenon, and peripheral polyneuropathy. The patient also experienced malaise, vertigo, and transient amaurosis whenever he was exposed to low temperatures. Skin biopsies of the livedo reticularis revealed marked dilatation of the small dermal blood vessels and circumscribed leukocytoclastic vasculitis. Essential cryofibrinogenaemia was diagnosed on the basis of detection of this cryoprotein in the chilled blood plasma with increased viscosity. Pulsed therapy with dexamethasone and cyclophosphamide resulted in marked relief of the symptoms, and cryofibrinogen was no longer detectable in the patient's plasma.
