Water-soluble contrast media, which have been employed in the examination of the lumbar spinal canal for 30 years, can sometimes result in severe complications, such as arachnoiditis, epileptic seizures, and myoclonic spasm. These complications have been seen less frequently since the advent of metrizamide, a new non-ionic water-soluble contrast medium. However, a further neurological complication has now arisen--mental disorder, varying in kind and degree; for example, organic psychosis and perceptual disturbance. Some characteristic cases are described. A series of 75 patients, all of whom received varying amounts of metrizamide for the purpose of cervical, thoracic and lumbar myelography, has been studied. Seven patients were found to have a pronounced organic psychosis and three patients had visual illusions or hallucinations. It is suggested that there is some degree of correlation between the total amount of iodine received and patient age. By careful enquiry and examination, similar disturbances were also found some 4-8 h after myelography with other water-soluble contrast media.

Benzodiazepine dependence is a frequent complication of regular prescriptions for 4 weeks or longer, occurring in almost one-third of patients. Although it is also manifested by tolerance to drug effects and occasional drug seeking behaviour, particularly in those prone to drug abuse, most dependence is characterised by a withdrawal syndrome on stopping treatment. The withdrawal syndrome includes symptoms of anxiety and those of perceptual disturbance such as depersonalisation, hypersensitivity of all major senses, dysphoria and (rarely) epileptic seizures and psychotic episodes. Risk factors for dependence include high dosage, use of more potent and short acting benzodiazepines, long duration of therapy and dependent premorbid personality characteristics. If none of these apply, benzodiazepines can be prescribed with safety.
