Artistic production in dyslectic children.

In the study of children with language problems, particularly in reading and writing, it has been observed that some have an outstanding ability to produce artistic pictures and objects. These productions are perceptive, well organized and generally contain much action. Despite their pictorial skill these patients may have only a rudimentary use of coded symbolic graphic forms. Others display moderate ability in reading and writing. These patients frequently have the disorganized overacctive behavior and the motor clumsiness that is so common in the dyslectic child; some, however, are biologically effective. From this material we entertain the hypothesis that picture (artistic) productions are generated by the sub-dominant cerebral hemisphere, and that this function is quite distinct from the coded graphic operations resident in the dominant hemisphere. If this hypothesis is correct, it would seem socially benefical to allow these patients to develop their unique artistic ability to its full capacity, and not to overemphasize the correction of the disturbed coded symbol operations in remedial training.

Pontocerebellar atrophy combined with vestibular-reticular degeneration.

A 41-year-old woman was hospitalized in 1939 with neurologic signs from which there was complete recovery over a two-year period. In 1965 she was readmitted because of increasing forgetfulness and inability to care for herself; there were no neurologic deficits. In June 1970 torticollis developed and persisted until her death 15 months later. No cerebellar signs were elicited, but increased muscle tone was prominent. The brain showed remarkable flattening of the inferior surface of the cerebellum; the pons was small. The medullary substance of the cerebellum and each branchium pontis appeared completely demyelinated. Transverse fibres were apparently absent in the central basis pontis. Microscopically in addition to the pontocerebellar atrophy there was degeneration of the vestibular system, reticular formation of the medulla oblongata and medial longitudinal fasciculi. The inferior olives showed only moderate neuronal degeneration in the caudal areas. Basal ganglia and thalamus showed some involvement in the pathological process. It is postulated that the vestibular-reticular system atrophy was the anatomic substrate for the torticollis, and apparently overshadowed cerebellar signs, which are ordinarily associated with pontocerebellar atrophy.
