Deficit syndrome in older schizophrenic patients.

Previous studies have reported that a proportion of younger schizophrenic patients have the "deficit syndrome," with persistent "negative" symptoms not secondary to factors other than the disease process (e.g., depression). Yet, there is scant information on the deficit syndrome in older schizophrenic patients. We studied 46 schizophrenic patients over age 45. Seventeen met the criteria for the deficit syndrome as described by Carpenter et al. (1988), 20 were considered definite nondeficit patients, and 9 could not be classified. The deficit schizophrenic patients had a significantly higher total score on the Scale for the Assessment of Negative Symptoms but similar scores on scales for positive symptoms, depressive symptoms, and overall psychopathology as compared with nondeficit patients. The deficit patients also had a nonsignificantly greater impairment on the Halstead-Reitan Battery. One notable difference between our results and those of Carpenter et al. was in the prevalence of deficit syndrome. We found the prevalence (37%) to be significantly higher than that reported in younger patients (15%). Pending confirmation using larger sample sizes, the increased frequency of the deficit syndrome in our study could possibly be attributed to aging or a longer duration of illness in our subjects.

The hands, and the mind, pre- and post-regression, in Rett syndrome.

Forty girls with Rett syndrome were included in a study of behaviour, with particular regard to the hands, before, during and after regression. Data was taken from examination of each girl, and in some cases from detailed developmental histories given by parents, and films taken before, during and after regression. The important findings are shown in two tables and described. Pre-regression abnormalities included hypotonia, jerky incoordination, an excess of patting or waving activity and involuntary movements which included alternate opening and closing of the fingers and twisting of wrists or arms. Hand use did not progress beyond the ten- to twelve-month stage. Language did not develop beyond the stage of one word utterances. When well-developed, the stereotyped hand movements were simple and clumsy, consisting of tapping, rubbing and clasping, with the hand moved as a unit. Before regression hands were usually separate, during regression usually together and thereafter with increasing age inclined to separate again. Voluntary hand use was observed when girls were relaxed and strongly motivated, particularly during musical interactions. The characteristic abnormalities of behaviour in pre-regression Rett syndrome, and hand behaviour in later childhood should allow earlier and more accurate diagnosis.

Hearing loss of Down syndrome adults.

Audiological hearing-test data were obtained for 51 Down syndrome adults. Depending upon hearing-loss criteria, from 51 to 74 percent of the subjects had some degree of hearing impairment. Correlation coefficients between these hearing-acuity measurements and receptive hearing vocabulary scores suggest a moderate relationship. These data indicate that Down syndrome adults are prone to a wide variety of hearing difficulties that may reflect a variety of ear pathologies. These data and other studies have shown that both Down syndrome adults and children need frequent hearing screening and, when indicated, otological and/or audiological management. When otological treatment will be of long duration, aural rehabilitation, including prescription amplification, may be indicated as an adjunctive therapeutic procedure.

An operant procedure for improving vocabulary definition performances in developmentally delayed children.

This report describes a training program in which operant procedures were used to improve the identification and definition of selected vocabulary words in three developmentally delayed children. Generalization from the training words was well established, as determined by responses to untrained vocabulary performance words. The results of this procedure suggest its application with other developmentally delayed children.

Procedural controls in group auditory perceptual listening tasks.

This article discusses experimental procedure controls that can assist in producing more reliable listening task experiments for investigators. Issues addressed relate to using appropriate equipment, tape-processing procedures, and listening sessions controls.
