Neurologic referrals to a psychiatric consultation-liaison service. A study of 199 patients.

The findings in a 199 neurology patients referred to a psychiatric consultation-liaison service are analyzed. Neurology referrals differ from general hospital referrals in reasons for referral and in patterns of diagnosis. The most common conversion symptoms seen are pain and pseudoseizures. The psychiatric diagnosis made in those patients with functional pain varies with the site of the pain. These two conversion symptoms, pain and pseudoseizures, have differing ages of onset and prognoses. A number of patients were given no psychiatric diagnosis and the reasons for this are discussed. The incidence of various neurologic diagnoses made in those patients referred to the consultation-liaison service is compared with the incidence of those diagnoses made in consecutive admissions to the neurology ward.

The use of midazolam for hypnosedative interviews.

The authors describe three cases in which midazolam was successfully used in diagnostic hypnosedative interviews. A discussion comparing and contrasting midazolam to other intravenous hypnosedatives is presented. The authors suggest that midazolam is an effective agent for diagnostic hypnosedative interviews and may be preferable to other agents when posthypnotic recollection of interview content is undesirable.

Neuro-ophthalmology and psychiatry.

Neuro-ophthalmology and psychiatry interact over several issues. The neuro-ophthalmologist can confirm the suspicion of nonorganic visual dysfunction by demonstrating the functional integrity of the visual system and the nonphysiologic nature of the visual complaints. He or she may recognize evidence of organic dysfunction in the patient with a presumed psychiatric diagnosis. In some cases, the pathology may be related to the use of certain psychiatric medications. Specialized examination techniques within the realm of neuro-ophthalmology may provide subtle information about the functional integrity of the central nervous system in patients with psychiatric disease. Clinical and investigational collaboration between the neuro-ophthalmologist and the psychiatrist will provide the most appropriate patient management and may further our understanding of the biological basis of psychiatry.

In defense of Pseudoseizure.

There continues to be disagreement over the best term for behavior that simulates an epileptic seizure. In the author's view, pseudoseizure is the most accurate of the expressions currently in use, and fears about its potentially damaging effects are unfounded. Even pseudoseizure, however, fails to convey the behavioral nature of the phenomenon in question, for it identifies what the problem is not, rather than what it is.

Intractable paroxysmal sneezing: a conversion reaction of adolescence.

A case of recurrent paroxysmal sneezing in an adolescent girl is reported with a review of the literature. The mechanisms of sneezing are described. Most cases appear to have a psychogenic etiology. We postulate that this is a conversion symptom in which the patient received secondary gain and probably represents a pre-oedipal conflict.

The lateralisation of pain.

Pain is more often lateralised on the left, except in the case of trigeminal neuralgia. The factors which promote lateralisation of pain are reviewed and it is noted that hysterical conversion symptoms are also more common on the left. Experimental evidence implies that the right hemisphere is less efficient than the left in processing cutaneous sensory input. Neurological and psychiatric data support the view that the right hemisphere is dominant for emotional experience and this may help to determine the left-sided preponderance of pain.

MMPI and headache: a special focus on differential diagnosis, prediction of treatment outcome, and patient-treatment matching.

The relation between personality characteristics and the psychological functioning of headache patients has long been a topic of interest. Early investigations focused on clinical and anecdotal reports while recent research has moved toward a more objective evaluation of headache groups by using the MMPI. However, the findings from diverse studies have not been integrated, nor has a rationale for the use of these data in the clinical management of headache been formally presented. The focus of this review is to present a concise, integrated analysis of previous group MMPI headache studies and apply these findings to differential diagnosis, prediction of treatment outcome, and client-treatment matching. Five selected clinical case studies indicating various degrees of psychopathology in migraine headache patients are presented to highlight treatment issues in support of an idiographic utilization of the MMPI for the clinical treatment of headache patients.

Epileptic seizures induced by sexual abuse. Pathogenic and pathoplastic factors.

Previous sexual abuse is now thought to be a common cause of non-epileptic seizures (pseudoseizures). However, since sexual abuse is common, a previous history of sexual abuse may also occur in people with actual epilepsy. We present six patients in all of whom sexual abuse may, by acting as a stressor in the already predisposed, have precipitated epilepsy and in some of whom the abuse may have affected the actual experiences of the epilepsy itself: all but one of the patients had partial seizures.

Histomorphometric analysis of osteopenia associated with endemic osteoarthritis (Mseleni joint disease).

Mseleni Joint Disease (MJD), a polyarticular osteoarthritis of uncertain etiology is endemic among the Tonga-Zulu tribe. The traditional diet is deficient in calcium, and palm wine (2-4% alcohol) is drunk widely. Patients with MJD are reported to be more osteopenic than those without. Iliac bone biopsies of 19 arthritic patients were examined by routine histomorphometry and revealed decreased trabecular bone volume (p less than 0.0005), increased resorption surfaces (p less than 0.01), decreased bone formation rate at the BMU (p less than 0.01) level and increased mineralization lag time (p less than 0.01). Six of the 19 patients (31.6%) had features of osteomalacia and six (31.6%) signs of osteoblast failure. The most likely cause of the bone disorder is calcium deficiency, but inanition, inactivity and alcohol abuse may have contributed. Although the joint disorder may have contributed to the bone disorder, the converse is unlikely the case.

Hyperactive action monitoring during motor-initiation in conversion paralysis: an event-related potential study.

Conversion paralysis (CP) is featured by a stress-induced tonic immobility. Although the neural correlates of this psychiatric condition remain largely unexplored, previous reports showed CP to be associated with anterior cingulate cortex (ACC) hyperactivity. We examined the ACC action monitoring function by recording event-related potentials (ERPs) when conversion patients (n = 6) with unilateral arm paresis made speeded responses with their affected and healthy arms on a flankers task. During this task, pre-response ACC action monitoring is reflected in the N2 ERP component, which is increased when incongruent stimuli lead to simultaneously activated competing response tendencies. The results showed that the N2 congruency effects were significantly increased for responses with affected hands compared to healthy hands. There were no such results for post-response monitoring. This study is the first to present electrophysiological correlates of action monitoring in CP and suggests ACC to be hyperactive when movements with affected arms are to be initiated.
