The cognitive limitations that typify Down syndrome, however, make it challenging to diagnose the co-occurring cognitive decline and behavioral changes of dementia, especially in the early period of dementia that is often termed mild cognitive impairment. Scientists recently reported that the telomeres (end regions of chromosomes) for chromosome 21 are shorter in people with Down syndrome who also have dementia or mild cognitive impairment than in individuals who have only Down syndrome. The shorter length of the chromosome 21 telomere was found to be highly sensitive and highly specific in distinguishing between individuals with Down syndrome who did and who did not have dementia or mild cognitive impairment. With further research, shorter telomere length could become a biomarker for early stages of dementia in individuals with Down syndrome. Such a biomarker could support decisions on treatment and interventions early in the devastating progression of dementia in people with Down syndrome.<br> Source: Jenkins, E.

In a recent study, scientists showed that children with Angelman syndrome exhibited more severe alterations in white matter pathways than did those in typically developing children, and some of these alterations were associated with the severity of their Angelman symptoms in language, cognitive, and social functioning. The findings suggest a generalized alteration in white matter throughout the brain in those with Angelman syndrome, with alterations in temporal white matter pathways potentially having a stronger clinical impact.<br> Source: Peters, S. U., Kaufmann, W. E., Bacino, C. A., Anderson, A. W., Adapa, P., Chu, Z., et al. (2011). Alterations in white matter pathways in Angelman syndrome. <em>Developmental Medicine & Child Neurology, 53</em>, 361-367.</p> <h5>Maternal Transmission of a Rare Genetic Variant is Associated with ASDs</h5> <p>The more that scientists search for genetic factors in ASDs, the more they find multiple types of abnormal genetic material at various chromosome sites, often with only weak associations with ASDs. A promising method used by some researchers is to investigate rare genetic variants that are known to be associated with a strong effect. With NIH support, a group of scientists focused on the GABRB3 gene. This mutated gene is strongly associated with two conditions (Angelman and Prader-Willi syndromes) that are inherited from a mother and have features of autism. The scientists found a rare “missense” mutation in the maternal GABRB3 allele associated with autism and a co-occurring childhood epilepsy. The research provides the first evidence of maternal transmission of a gene variant within a chromosomal region that is known to be associated with autism. The research also suggests that, as with other complex diseases, rare genetic variants with stronger ASD risk effects will be found in common allele mutations with weaker effects.<br> Source: Delahanty, R. J., Kang, J. Q., Brune, C. W., Kistner, E. O., Courchesne E., Cox, N. J., et al. (2011).

This model uses a style of therapy that emphasizes breaking activities into small, measurable units that are then reinforced with reward. In this study, researchers performed a randomized, controlled trial of the intervention over 2 years and showed that it led to improvements in IQ, language abilities, and adaptive functioning (i.e., the skills necessary for everyday activities). During the study, 48 toddlers age 1½ to 2½ years who had been diagnosed with an ASD were randomly assigned to receive the ESDM or an intervention commonly available in the community. Children in the ESDM group received an average of 15 hours per week working one-on-one with a therapist trained in the technique. Parents were taught to continue the therapy at home for at least 5 hours per week. The other 24 toddlers worked with therapists in the area, receiving a range of conventional therapies, for an average of 9 hours per week and received an additional 9 hours of therapy in a specialized preschool or other group program. Overall, the average number of intervention hours was similar for the two groups. After 2 years, the children receiving the ESDM intervention showed a 17.6-point increase in IQ, versus a 7-point increase in the comparison group working with community therapists. The children in the ESDM group also showed continued growth in adaptive behaviors, such as brushing their teeth, getting dressed, and eating with utensils, while the other children fell further behind developing peers.<br> Source: Dawson, G., Rogers, S., Munson, J., Smith, M., Winter, J., Greenson, J., et al.

In Fragile X syndrome, a gene mutation leads to the absence of the fragile X mental retardation protein (FMRP), which helps regulate protein production and signaling. Without FMRP to perform this function, individuals with Fragile X syndrome produce excess amounts of certain proteins at neuronal synapses. This leads to structural changes and an impairment of the ability of cells to respond to chemical signals, interfering with learning and memory. In the mouse model of Fragile X syndrome, inhibiting the action of the PI3-kinase enzyme decreased the synaptic proteins and could potentially reverse the resulting structural changes. The drug was able to restore normal levels of protein production at synapses, suggesting that PI3-kinase inhibitors could help improve learning and cognition in individuals with Fragile X syndrome.<br> Source: Gross, C., Nakamoto, M., Yao, X., Chan, C.

There is no effective therapy for DMD. In boys, a typical progression of the disease involves muscle weakness by age 5, becoming wheelchair bound by the early to middle teens, and death from respiratory or heart failure by the early twenties. Losartan, a drug used to treat high blood pressure, has shown positive results on improving muscle function and strength in short-term studies of animal models with DMD. The next logical step was to conduct longer-term studies in animals. In addition, previous animal studies have not determined losartan’s impact on cardiac function. Identifying cardiovascular problems is especially important because heart failure is a common cause of death in young men with DMD.</p> <p>Scientists examined the effects of long-term losartan treatment in mice with DMD. Researchers found that after long-term treatment with losartan, 88% of treated mice were alive, compared with only 44% of untreated mice. While cardiac muscle function was significantly preserved in the treated mice, there appeared to be no changes in the weight, morphology, or function of skeletal tissue. These findings suggest that losartan could be an important prophylactic treatment for heart disease associated with DMD but that the drug may not have a positive impact in the long run on DMD-associated skeletal muscle disease.<br> Source: Bish, L.

This is a serious problem and even dangerous if caregivers or others cannot tell whether the individual is experiencing pain. Researchers tested a system based on well-defined discrete facial expressions to determine whether such a system could be used to assess pain in nonverbal adults with intellectual disability. The system uses 16 discrete facial movements, such as “lowering the brow,” “lip pucker,” “eyes closed,” and “jaw drop,” to monitor responses to sensory stimuli, including pain. The 44 individuals tested included 35 with profound intellectual disabilities, many of whom were completely nonverbal. Twenty-nine of the individuals exhibited self-injurious behavior. Five sensory stimuli were given: pinprick, warm, cool, deep pressure, and light touch.</p> <p>The individuals tested had greater facial activity in response to stimuli than did a control group with no stimuli. Females showed significantly more facial activity than males, and individuals with chronic self-injurious behavior were more expressive than comparable individuals without that problem. The results demonstrated that individuals with significant intellectual disabilities reliably react to sensory stimulation regardless of verbal ability, and that observation of discrete facial movements can be used to assess pain in this highly vulnerable population. The observation of heightened expression in the self-injurious behavior group is contrary to a long-standing belief that this group has a blunted perception of pain. This result warrants additional attention regarding pain and sensory thresholds when developing therapies for self-injurious behavior in nonverbal adults with intellectual disabilities.<br> Source: Symons, F.
