    The present study aimed to describe the kidney function profile – serum creatinine and estimated glomerular filtration rate (eGFR), and to examine the relationships of predisposing factors to abnormal serum creatinine in people with intellectual disabilities (ID). Data were collected by a cross-sectional study of 827 aged 15–18 years adolescents with ID who participated in annual health examinations as they enrolled into special education schools in Taiwan. We used serum samples to determine participants’ creatinine profiles, and the Cockcroft–Gault formula to calculate the data of eGFR to present the chronic kidney disease. The results found 22% of the participants have...

    In addition to hypotonia and relative sarcopenia, patients with Prader-Willi syndrome (PWS) show reduced spontaneous physical activity and gait disorders. Scant evidence exists that daily muscle training increases their lean mass and physical activity levels. Whether adequate long-term physical training is feasible and effective in improving muscle function and gait in PWS is still unknown.Eleven adult PWS patients (mean age: 33.8±4.3 years; mean BMI: 43.3±5.9kg/m2) admitted to our hospital were enrolled in this study. During their hospital stay they attended a 2-week rehabilitation program which included supervised exercise sessions. At discharge, Group 1 (6 patients) continued the same exercises at...

    To develop prevention activities, an analysis is conducted of child and parent characteristics that occur significantly more often among children with a mild intellectual disability and behavior problems than among children with a mild intellectual disability and no behavior problems and their families. The sample consisted of 45 children attenting schools for special education. Data were collected from the children, their parents, and their teachers. The instruments used are the Dutch version of the Parenting Stress Index, the Nijmegen Child-Rearing Situation Questionnaire and the Strenghts and Difficulties Questionnaire for parents, teachers and children. On the basis of the results of...

    Attention Deficit Hyperactive Disorder (ADHD) and Developmental Coordination Disorder (DCD) are two developmental disorders with considerable comorbidity. The impact of Methylphenidate (MPH) on ADHD symptoms is well documented. However, the effects of MPH on motor coordination are less studied. We assessed the influence of MPH on motor performance of children with comorbid DCD and ADHD. Participants were 18 children (13 boys, mean age 8.3 years) diagnosed with comorbid DCD and ADHD. A structured clinical interview (K-SADS-PL) was used to determine psychopathology and the Movement Assessment Battery for Children–Checklist were used to determine criterion for motor deficits. The Movement Assessment Battery...

    This paper presents an overview of the studies directed at helping post-coma persons with minimally conscious state improve their adaptive behavior. Twenty-one studies were identified for the 2000–2010 period (i.e., a period in which an intense debate has occurred about diagnostic, rehabilitative, prognostic, and ethical issues concerning people with severe acquired brain injury). Three of the 21 studies involved transcortical magnetic or deep brain stimulation. Six studies focused on the provision of multisensory stimulation or music therapy. The remaining 12 studies involved the use of response-related (contingent) stimulation and assistive technology. The outcomes of the studies, which were generally reported...

    Graphical abstract

     Research highlights: ▶ The overview covers intervention studies for persons in a minimally conscious state. ▶ Evidence on transcortical and deep brain stimulation is limited. ▶ Effects of multisensory and music stimulation need to be taken with caution. ▶ Effects of learning setups and assistive technology appear fairly robust.

    Using the Japanese version of home form of the ADHD-RS, this survey attempted to compare the scores between the US and Japan and examined the correlates of ADHD-RS. We collected responses from parents or rearers of 5977 children (3119 males and 2858 females) in nursery, elementary, and lower-secondary schools. A confirmed factor analysis of ADHD-RS confirmed the two-factor solution (Inattentive and Hyperactive-Impulsive) same as previous studies. ADHD-RS scores were not related to IQ, but were negatively associated with standardized achievement test scores. Males showed stronger ADHD tendencies than did the females, and the scores ended to decline as the children...

    Increases in the scores on IQ tests across generations have been called the Flynn effect (FE). One of the unresolved questions is whether the FE affects all subsamples of the intellectual ability distribution equally. The present study was aimed at determining the size of the FE in moderately mentally retarded individuals. A nonverbal intelligence test developed for children, the Snijders-Oomen Nonverbal Intelligence Test (SON), was administered to 32 retarded adults with a mental age of 3–6 years. Sixty-nine children with a biological age in the same range and with normal intelligence served as a comparison group. Both an older and...

    We taught seven preschoolers with developmental disabilities to point-and-click with a computer mouse. The computer-based training program consisted of three parts, based on a task analysis of the behavioral prerequisites to point-and-click. Training 1 was designed to shape moving the mouse. Training 2 was designed to build eye–hand coordination by teaching the children to move the on-screen cursor onto specific items on the screen. Training 3 was designed to teach pressing and releasing the mouse button. An instructor provided prompts and blocking to facilitate skill acquisition. A multiple baseline design across participants was used to evaluate the effectiveness of the...

    Co-existence of disorders – including attention-deficit/hyperactivity disorder, oppositional defiant disorder, tic disorder, developmental coordination disorder, and autism spectrum disorder – and sharing of symptoms across disorders (sometimes referred to as comorbidity) is the rule rather than the exception in child psychiatry and developmental medicine. The acronym ESSENCE refers to Early Symptomatic Syndromes Eliciting Neurodevelopmental Clinical Examinations. It is a term I have coined to refer to the reality of children (and their parents) presenting in clinical settings with impairing child symptoms before age 3 (−5) years in the fields of (a) general development, (b) communication and language, (c) social inter-relatedness,...

    Sight-word instruction is the most common method of reading instruction for students with Moderate Intellectual Disabilities reported in the research literature. The purpose of this study was to go beyond instruction of single word units to instruction of multiple-word phrases. This study demonstrated the instruction of reading and comprehending individual words and connected text through the use of simultaneous prompting. Instruction progressed through a series of phases which systematically introduced various parts of speech and combinations of parts of speech. Following acquisition, students demonstrated generalization across connected text found in community environments and leisure-reading materials.

    Objective assessment of memory functioning is an important part of evaluation for Dementia of Alzheimer Type (DAT). The revised Picture Recognition Memory Test (r-PRMT) is a test for visual recognition memory to assess memory functioning of persons with intellectual disabilities (ID), specifically targeting moderate to severe ID. A pilot study was performed to investigate whether the r-PRMT could differentiate DAT-related memory decline from pre-existing poor memory functioning of persons with moderate to severe ID. The r-PRMT scores were compared between 26 participants with DAT and moderate to severe ID and 33 controls with similar levels of ID. The results revealed...

    Moebius sequence is a rare congenital disorder usually defined as a combination of facial weakness with impairment of ocular abduction. It is questionable, whether there is a strong association of the sequence with autism spectrum disorders (ASDs) as suggested in some earlier case reports and studies. Twenty-two participants with Möbius sequence aged 6–16 years followed a request of the German Moebius foundation to participate in a nationwide study. All patients had a physical examination and intelligence testing. Primary caregivers were asked to complete two screening measures of ASD (Behaviour and Communication Questionnaire, VSK; Marburger Asperger's Syndrome Rating Scale, MBAS). For...

    We investigated the effectiveness of instruction and video feedback on correct trainer behaviour and the use of prompt sequences of 10 direct-care staff during one-to-one training with 10 young children with severe intellectual disability. Following baseline, trainers received instruction (written and verbal) concerning (in)correct trainer behaviour and response prompting. Then, video feedback was implemented and consisted of (a) interrupting a video presentation if an error occurred, (b) providing positive feedback, and (c) prompting the trainer to avoid errors or omissions. Data were collected in a non-concurrent multiple baseline design. The results showed that instruction and video feedback were highly effective...

    We investigated the influences of two different suprapostural visual tasks, visual searching and visual inspection, on the postural sway of children with and without autism spectrum disorder (ASD). Sixteen ASD children (age=8.75±1.34 years; height=130.34±11.03cm) were recruited from a local support group. Individuals with an intellectual disability as a co-occurring condition and those with severe behavior problems that required formal intervention were excluded. Twenty-two sex- and age-matched typically developing (TD) children (age=8.93±1.39 years; height=133.47±8.21cm) were recruited from a local public elementary school. Postural sway was recorded using a magnetic tracking system (Flock of Birds, Ascension Technologies, Inc., Burlington, VT). Results indicated...
