Anatomical characterization of athetotic and spastic cerebral palsy using an atlas-based analysis.

Purpose: To analyze diffusion tensor imaging (DTI) in two types of cerebral palsy (CP): the athetotic-type and the spastic-type, using an atlas-based anatomical analysis of the entire brain, and to investigate whether these images have unique anatomical characteristics that can support functional diagnoses.

Materials And Methods: We retrospectively analyzed the DTI of seven children with athetotic-type, 11 children with spastic-type, and 20 healthy control children, all age-matched. The severity of motor dysfunction was evaluated with the Gross Motor Function Classification System (GMFCS).

Athetotic and spastic cerebral palsy: anatomic characterization based on diffusion-tensor imaging.

Purpose: To evaluate the anatomy of deep gray and white matter structures in children with athetotic cerebral palsy (CP) and those with spastic CP by using diffusion-tensor (DT) imaging and to investigate whether these types of CP have unique anatomic correlates that can support their diagnosis and prognosis.

Materials And Methods: This study was approved by the institutional review board of each participating institution, and written informed consent was obtained from the parents of each patient. DT imaging was used to retrospectively evaluate 19 children with clinically diagnosed athetotic CP (mean age, 3.

Movements and postures of infants aged 3 to 5 months: to what extent is their optimality related to perinatal events and to the neurological outcome?

Background: The quality of spontaneous general movements (GMs), assessed in the individual infant, has emerged as one of the most reliable and valid predictors especially of severe neurological impairments.

Aims: To implement a more detailed assessment of GMs and co-existing movements and postural patterns in a rehabilitation clinic, and to examine to what extend is the optimality of movements and postures of infants aged 3 to 5 months related to perinatal events and the neurological outcome.

Study Design: Prospective study of 41 infants (15 boys and 26 girls; 11 infants born preterm) admitted to the Department of Paediatric Neurology and Rehabilitation of the St.

Quantitative diffusion tensor tractography of the motor and sensory tract in children with cerebral palsy.

Aim: the aim of this study was to compare the findings of quantitative diffusion tensor tractography of the motor and sensory tracts in children with cerebral palsy (CP) and typically developed comparison individuals, and also to evaluate the correlation with gross motor function.

Method: thirty-four children with CP (mean age 2y 2.mo, SD 2y 0mo; 19 with spastic diplegia, eight with hemiplegia, six with spastic quadriplegia, and one with spastic triplegia) and 21 healthy comparison children (mean 2y 1.

Symmetrical central tegmental tract (CTT) hyperintense lesions on magnetic resonance imaging in children.

The central tegmental tract (CTT) is mainly the extrapyramidal tract connecting between the red nucleus and the inferior olivary nucleus. There are only a few case reports describing CTT abnormalities on magnetic resonance imaging (MRI) in children. Our purpose was to evaluate the frequency of CTT lesions and their characteristics on MRI, and to correlate the MR imaging findings with clinical features.

[An estimation chart for the possibility of aspiration in patients with severe motor and intellectual disabilities: its reliability and accuracy].

Although the most common cause of death in patients with severe motor and intellectual disabilities (SMID) is aspiration pneumonia, there are no criteria to detect aspiration. We have been making an evaluation tool to detect aspiration in patients with SMID easily, in cooperation with the project of comprehensive study of disability, social health, and welfare, supported by the Ministry of Health, Labor and Welfare, Japan. Here we studied the reliability and accuracy of the 2001 edition of the "questionnaires for functions of eating and swallowing" and "estimation chart for the possibility of aspiration" in 20 patients with risk of aspiration (13 with cerebral palsy, six with acquired cerebral palsy and one with muscle disease).

Multi-institutional study on the correlation between chromosomal abnormalities and epilepsy.

While there is an abundance of literature describing the association of chromosome aberrations with epilepsy, only a few refer to the detailed features of epilepsy. It is important to investigate the associations between specific chromosome abnormalities and features of epilepsy to identify genes involved in epilepsy and treat them more effectively. We investigated the correlation between specific chromosome aberrations and epilepsy by sending questionnaires to the members of Kyoto Multi-institutional Study Group of Pediatric Neurology.

Motor outcome differences between two groups of children with spastic diplegia who received different intensities of early onset physiotherapy followed for 5 years.

The objective of this study is to determine the clinical effectiveness of early onset long-term intensive physiotherapy on motor development in children with spastic diplegic cerebral palsy (CP). The study was a non-randomized cohort study with 62 months (mean) follow-up. The participants were ten infants who were first examined before 3 months of age corrected for prematurity.

Unilateral cerebral polymicrogyria with ipsilateral cerebral hemiatrophy.

We evaluated six children in whom MR imaging showed unilateral cerebral polymicrogyria associated with ipsilateral cerebral atrophy and ipsilateral brain stem atrophy. The aim of this study was to clarify whether this disorder based on neuroimaging constitutes a new homogeneous clinical entity. The subjects were six children whose ages at the time of MR imaging ranged from 8 months to 11 years.
