Intractable depression or psychosis.

OBJECTIVE: Some patients with treatment resistant depression may have a difficult to recognize and therefore untreated thought disorder. Even a subtle disorder may significantly impact patients' lives. This case illustrates a mechanism for identifying and treating this subgroup of patients. METHOD: The treatment of a 67-year-old female with intractable depression is described. RESULTS: The Rorschach Exner Comprehensive System identified the presence of a thought disorder with four out of five conditions positive on the Schizophrenia Index and five out of seven conditions positive on the Depression Index. Low-dose risperidone was added to the patient's medications with excellent results. Post-testing indicated that the Schizophrenia and Depression Indices were no longer positive. CONCLUSION: A subgroup of patients with intractable depression may have an underlying thought disorder that can be identified with the Rorschach and successfully treated with low-dose antipsychotic medication.

Developmental and sex differences in sensory and motor functioning.

The sensory and motor functioning of normal children (N = 119) ages 4 to 13 years old were examined for developmental and sex differences in relation to neuropsychological functioning. Sensory and motor subtests of the Dean-Woodcock Neuropsychological Assessment System (D-WNAS), a standardized instrument, were administered. Significant differences between the older and younger children were found, suggesting that developmental differences exist for sensory and motor functioning. The older children significantly outperformed the younger children on all subtests except for visual confrontation. Differences between males and females and the interaction between sex and age were not significant. The present findings coincide with previous research showing clear maturational differences in sensory and motor functions.

Validity and reliability of rapidly alternating movement tests.

Two studies investigated the interrater reliability and concurrent validity of tests of rapidly alternating movement. Study I examined the interrater reliability of three different tests, "finger tapping" to the adjacent thumb, "table tapping," and "hand to thigh" alternating movements. Using normal participants the results indicated poor interrater agreement for the "hand to thigh" test and modest relationship for both types of finger tapping. However, for each test the number of recorded repetitions differed significantly between raters. Study 2 examined the concurrent validity of two mechanical measures of finger tapping. The scores of 36 normal participants was compared using a mechanical digital counter and a calculator. Results indicated that the use of the calculator as a counter was highly related to the results with a mechanical digital counter. Conclusions suggested the use of a mechanical apparatus is more reliable than human observations. In addition, the use of an inexpensive apparatus will produce results similar to the manual finger tapping apparatus commonly used in neuropsychological batteries.

Perinatal risk factors as predictors of developmental functioning.

This study examined the relationship between perinatal risk factors and developmental functioning for a referred population of 216 children. A canonical correlation analysis indicated that 31% of the variability in developmental information could be predicted from perinatal events. The results were interpreted as lending support to a multivariate link between perinatal complications and developmental functioning for referred children.

Neuropsychological significance of IQ summary scores.

A canonical correlation between summary intelligence scores and neuropsychological tests for 423 learning-disabled children was performed. Results showed a significant relationship between WISC-R global intelligence scores and tests of the Halstead-Reitan's Neuropsychological Battery for Older Children (HRNB-C), Rc = .53, p < .001. While measures were found to share commonality, both were found to provide unique information. The clinical implications of these findings were discussed.
