Characterological traits of recovered patients with panic disorder and agoraphobia.

Three self-rating personality inventories were administered to 33 patients who had recovered from panic disorder associated with agoraphobia and to 33 healthy subjects matched for sociodemographic variables. The personality inventories comprised the Tridimensional Personality Questionnaire (TPQ), which provides three major dimensions (novelty seeking, harm avoidance and reward dependence), the Anxiety Sensitivity Index (ASI) and the Emotional Inhibition Scale (EIS). Agoraphobic patients reported significantly more TPQ harm avoidance and anxiety sensitivity than controls. Although these findings might have been influenced by residual anxiety symptoms in panic-free patients and could also apply to patients with other anxiety disorders, they suggest that harm avoidance and anxiety sensitivity may be risk factors for developing agoraphobia and panic disorder. There may be overlap between this characterologic cluster and prodromal symptoms of panic disorder with agoraphobia, such as anxiety, phobias and hypochondriasis.

The use of intonation to communicate in pervasive developmental disorders.

The objective of this paper was to employ a functional linguistic approach to explore pragmatic failure in the spontaneous speech of subjects with pervasive developmental disorders (PDD). Patterns of intonation use were compared among subjects with Asperger's syndrome (AS), high-functioning autism (HFA), and psychiatric out-patient controls (OPC) with a variety of non-specific social problems. Written transcripts and audio-recordings were used to measure rates of various intonation types relative to the amount of speech produced. The major finding of the study was that the HFA subjects less often tend to employ useful patterns of intonation for communication than the AS or OPC groups. This suggests that HFA either send random intonation signals to hearers or else demonstrate systematic misuse of the linguistic system. AS subjects differed little from the controls. The implications of these results for understanding the communicative failure of PDD subjects is discussed.

Asperger's syndrome and autism: neurocognitive aspects.

The objectives of this study were to see: (1) whether children with Asperger's Syndrome (AS) have similar neurocognitive deficits compared to nonretarded, or high-functioning autistic (HFA) children; and (2) whether the essential cognitive deficit among these children is in language or abstract problem solving. Subjects with AS, HFA, and a control group of socially impaired child psychiatric outpatient controls (OPC) were compared on a battery of neuropsychological tests. The results indicated that the AS and HFA groups differed little but that large differences from the OPC were observed on all tests. When the AS and HFA with FSIQ above 85 were compared to the OPC, outstanding deficits on motor coordination, language comprehension, and facial recognition were observed. Finally, some evidence is presented to suggest that the pattern of deficits of AS and HFA subjects varied by developmental level. The implications of these results for a neurological theory of autism are discussed.

Mental retardation in heterozygotes for the fragile-X mutation: evidence in favor of an X inactivation-dependent effect.

The still debated question of whether the expression of mental retardation in heterozygous carriers of the Martin-Bell syndrome is influenced by X inactivation has been investigated in a group of phase-known double heterozygotes for the FRA-X mutant and the G6PD Mediterranean variant. In these individuals, the number of somatic cells (fibroblasts or red cells) with an active FRA-X chromosome could be assessed through the G6PD phenotype at the single-cell level. The data reported indicate a significant inverse correlation between the IQ level (as measured by the Wechsler-Bellevue test) and the percentage of fibroblast cells with an FRA-X active chromosome. In contrast, no significant correlation was found when the IQ level and red cell data were compared, thus suggesting the occurrence of somatic selection against hematopoietic stem cells with an active FRA-X chromosome.

A follow-up study of high-functioning autistic children.

It is well known that IQ is an important prognostic variable in the outcome of autistic children. There are, however, very few data available on the outcome of nonretarded autistic children as adults. We identified 16 such probands from records and followed them up between 11 and 27 years since discharge from a center specializing in the assessment of autistic children. There were 12 males and 4 females, average age was 26, and mean IQ was 92 (range 68-110). Although the majority were functioning poorly in terms of occupational-social outcome and psychiatric symptoms, a surprising number (4) had a very good outcome and might be considered recovered. The severity of early autistic behavior was a poor predictor of outcome, but neuropsychologic measures of nonverbal problem solving were highly correlated with outcomes. The results of the study indicate that a small percentage of nonretarded autistic children can be expected to recover to a substantial degree.

Asperger's syndrome and autism: comparison of early history and outcome.

The authors compared children with Asperger syndrome (AS) with high-functioning autistic children and psychiatric outpatient controls on measures of early history and outcome. In terms of their early history, the autistic probands showed more social impairment, a higher frequency of echolalia and pronoun reversal, and a more restricted range of activities than the AS group. Cluster analysis suggested refinements to the diagnostic criteria, which resulted in larger differences between the groups on these early history measures. In terms of their outcome, the autistic probands spent more time in special education classes but developed fewer accessory psychiatric symptoms than the AS children. It was clear, however, that there were no substantive, qualitative differences between the AS and autistic groups, indicating that AS should be considered a mild form of high-functioning autism. The inclusion of AS among the autistic spectrum of disorders has implications both for aetiological studies and for prevalence estimates of the pervasive developmental disorders.

Psychosomatic assessment of hirsute women.

Psychiatric illness, psychological distress and illness behavior were investigated in 30 hirsute women and 30 nonhirsute healthy control subjects matched for sociodemographic variables. The majority of patients showed a good psychological adaptation to illness: they did not report significantly more anxiety, depression, and abnormal illness behavior than controls. One-sixth of the patients, however, suffered from a clinically meaningful affective disorder. Further, hirsute patients displayed significantly more hostility and irritable mood than controls (p less than 0.01).

Cardiac neurosis and psychopathology.

Psychiatric illness according to DSM-III-R criteria was investigated in 54 consecutive patients suffering from cardiac neurosis (neurocirculatory asthenia or Da Costa's syndrome). Thirty-seven of the 54 patients (68.5%) were found to suffer from a psychiatric disorder. Generalized anxiety disorder, social phobia and panic disorder accounted for most of the diagnoses. Panic disorder was frequently preceded by (and associated with) generalized anxiety, phobic avoidance and hypochondriasis. The results should alert the physician to inquire for symptoms of an anxiety disorder when a patient presents with cardiac neurosis.

Hypochondriacal symptoms in pregnancy.

Illness attitudes were evaluated in 26 pregnant women and 26 control subjects matched for sociodemographic variables, by means of a self-rating scale, on three different occasions. In each trimester of pregnancy, women displayed more hypochondriacal fears and beliefs and conviction of disease (disease phobia) than normal controls (p less than 0.001). The findings should alert physicians to ask their pregnant patients whether they are preoccupied with fear of dying, or are concerned that they suffer from an undiagnosed physical illness, or dread a specific illness such as cancer or heart disease. Hypochondriacal fears and beliefs are liable to affect the well-being and health attitudes of pregnant women. If properly recognized, they may effectively be treated.

Capgras syndrome--the many avenues to delusional misinterpretation.

The case of a 47 year old woman with Capgras' Syndrome is presented. Despite her misinterpretation of acoustic and visual clues, multiple investigations and extensive neuropsychological testing failed to implicate an organic basis upon which to explain her delusional belief. The authors conclude that single explanatory hypotheses--psychological or neurological--may preclude an appreciation for the heterogeneity of the syndrome.

Reduced striatal glucose consumption and prolonged reaction time are early features in Huntington's disease.

Striatal glucose consumption was measured by positron emission tomography in 4 male patients, aged 16-27, suffering from Huntington's disease and in 3 age-matched control subjects. Symptoms had been present for 3 years or less; they were mainly psychiatric. Two of the patients had no chorea although the time taken to initiate a movement was prolonged and there was some reduction in the speed at which movements could be executed. Caudate atrophy was absent or minimal by CAT scan yet striatal glucose consumption was markedly reduced in all of the patients. It is suggested that striatal glucose consumption is largely determined by the functional integrity of spiny neurones in the striatum.
