Disorders of movement after hemiplegia have been described for more than a century, but their pathological anatomy and physiology have remained poorly understood because of ambiguous terminology and incomplete studies. We examined the brains of 5 patients which had been serially sectioned where there had been well documented pure motor hemiplegia acquired in childhood. In 4 patients handicapped by hemiathetosis the main lesion was partial destruction of the caudate nucleus and putamen. In the fifth case, where non-disabling involuntary movements only appeared in later life, there was gliosis of the caudate nucleus and thalamus. Striatal lesions produce involuntary movement disorders if the corticospinal and other major motor tracts are partly intact. We propose that degeneration of the thalamic nuclei receiving striatal efferents (ventralis anterior, ventralis lateralis and centrum medianum), wheter primary or secondary, appears to remove an essential modulating influence on the corticospinal system which can only become manifest if this system is relatively preserved.

Two-point discrimination (TPD) was measured on eight points of the upper extremities of 220 children with cerebral palsy aged between seven and 14 years. 46 had classical diplegia, 23 had mildly spastic diplegia (without adductor spasms), 86 had hemiplegia, 26 had generalized dyskinesia, 10 had right- and four had left-sided hemiathetosis and 25 had quadriplegia. TPD was decreased in all cases compared with normal controls: slightly more for the classical forms of diplegia and on the paretic side of those with hemiplegia, slightly less in athetoid children. This adds further evidence to the authors' previous observations that sensory disorder is an integral part of the clinical picture of cerebral palsy.

Hereditary hemihypotrophy hemiparesis hemiathetosis syndrome (HHHH; OMIM 306960) was first reported in a family with congenital left hemiplegia in two males and moderately affected females. We describe a family with three males demonstrating congenital right hemiplegia with porencephalic lesions of the left internal capsule and putamen, or the periventricular white matter just above the internal capsule. Clinical findings within each family are limited to the same side, though sidedness differed between families. Both pedigrees were most consistent with X-linked inheritance. Genome-wide linkage analysis in our family further supports a locus for HHHH on chromosome X.
