[PMID: 39180809 DOI: 10.1016/j.ejpn.2024.08.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2024] [Revised: 08/01/2024] [Accepted: 08/16/2024] [Indexed: 08/27/2024]
Abstract
PURPOSE The aim of this study was to examine the cognitive and emotional-behavioural outcomes of Turkish children with Duchenne muscular dystrophy (DMD) in comparison with healthy peers, to determine its relationship with motor functions, and to analyse the difference of cognitive and emotional-behavioural outcomes according to the site of mutations. METHOD Children aged 7-16 years with DMD (n = 68) and age-matched typically developing children (n = 33) were included in the study. The cognitive and emotional-behavioural status and the motor functions were assessed in detail. Children with DMD also divided into two groups as "proximal" and "distal" site mutation groups to compare the cognitive and emotional-behavioural outcomes. RESULTS The children with DMD and typically developing children were similar in terms of age and body mass index (p > 0.05). Significant differences were found between children with DMD and typically developing peers in almost all subtests of both cognitive and emotional-behavioural assessments (p < 0.05). Cognitive and emotional-behavioural parameters were weakly correlated with specific motor parameters responsive to cognitive functioning (p < 0.05). Children with distal site mutation performed significantly worser than those with proximal site mutation in particular cognitive subtest (p < 0.05). CONCLUSIONS It is concluded that comprehensive and detailed evaluation of cognitive and emotional-behavioural features of children with DMD is essential for better implementation of rehabilitation programs to maintain motor function which especially requires cognitive ability, since a Turkish cohort represented challenges in particular domains of cognitive and emotional-behavioural areas. CLINICAL TRIAL REGISTRATION NUMBER NCT05661071.

Abstract
Duchenne muscular dystrophy (DMD) is an X-linked progressive neuromuscular disorder with a distinct cognitive profile including decreased verbal span. Children with DMD are also at risk for lower scores on academic achievement tests and increased behavioral problems. Longitudinal analyses generally reveal a stable intellectual profile, although attention and behavioral problems may negatively impact longitudinal IQ scores. To date, no study has reported on reading over time in DMD. Reading performance was assessed longitudinally in children with DMD, examining for potential contributions to the trajectory. Retrospective data analysis on assessments completed at baseline, year 2, and year 4 on 26 boys with DMD and 27 unaffected sibling controls (age at baseline: DMD 8 ± 1.4, controls 9 ± 2.6) indicated that children with DMD performed slightly, yet significantly, worse than controls on reading skills, but the longitudinal trajectory of reading skills for children with DMD and controls was not significantly different. Verbal span at time 1 was uniquely associated with later reading skills in children with DMD. Behavior was not associated with declines. The results confirm that children with DMD underperform on reading tasks and align with previous research suggesting that cognitive skills in DMD are stable over time.

Abstract
Dystrophin loss due to mutations in the Duchenne muscular dystrophy (DMD) gene is associated with a wide spectrum of neurocognitive comorbidities, including an aberrant unconditioned fear response to stressful/threat stimuli. Dystrophin-deficient animal models of DMD demonstrate enhanced stress reactivity that manifests as sustained periods of immobility. When the threat is repetitive or severe in nature, dystrophinopathy phenotypes can be exacerbated and even cause sudden death. Thus, it is apparent that enhanced sensitivity to stressful/threat stimuli in dystrophin-deficient vertebrates is a legitimate cause of concern for patients with DMD that could impact neurocognition and pathophysiology. This review discusses our current understanding of the mechanisms and consequences of the hypersensitive fear response in preclinical models of DMD and the potential challenges facing clinical translatability.

Abstract
It has long been reported that neuropsychological deficits may be present in dystrophinopathies, specifically non-progressive cognitive impairment and a global deficit in executive functions; this neurocognitive profile has been less explored in patients with Becker than Duchenne muscular dystrophy (BMD/DMD). We conducted a longitudinal study to explore the evolution of neuropsychological and behavioural profile in a cohort of paediatric BMD. Seventeen patients with BMD without intellectual disability were assessed using a full battery of tests, including intellectual, adaptive and executive functioning, language and behavioral features. Tests were performed at baseline and after 12 months. The results showed adequate cognitive and adaptive profile with falls in Working Memory, as well as lower scores in executive functions. An improvement was observed in Processing Speed. Behavioral questionnaires confirmed a negative trend, while in normal ranges. We found a statistically significant difference between T0 and T1 in some items exploring executive functions. No statistically significant difference was observed stratifying patients by mutation site or IQ level. In conclusion, our study suggests that BMD patients have a stable neurocognitive profile, while a deflection in the executive functions may be observed. We recommend a careful monitoring to intercept learning disabilities and promptly start a multimodal rehabilitation.

Social cognition in DMD and BMD dystrophinopathies: A cross-sectional preliminary study. Clin Neuropsychol 2024; 38:219-234. [PMID: 37081823 DOI: 10.1080/13854046.2023.2202332] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Accepted: 04/07/2023] [Indexed: 04/22/2023]
Abstract
Objective: The dystrophinopathies called Duchenne and Becker muscular dystrophies (DMD/BMD) are rare, progressive, incurable, and life-limiting paediatric-onset neuromuscular diseases. These diseases have long been associated with specific neuropsychological deficits. However, the performance of these patients in the social cognition domain has not been properly investigated. Thus, the main objective of this study was to compare the performance on social cognition between DMD/BMD patients and healthy age-matched boys. Method: This cross-sectional study included 20 DMD/BMD children and adolescents and 20 healthy controls. The protocol included the Social Perception Domain of the NEPSY-II, the Reading the Mind in the Eyes Test - Child and Happé's Strange Stories test. General intelligence was controlled to eliminate the possible influence of covariables. All the assessments were performed remotely. Results: Most social cognition tasks were worse in patients with DMD/BMD than in matched healthy controls. These differences remained even after controlling for the general intelligence variable, with the exception of Total Disgust Errors (F = 1.462, p = .234, η2p= .038) and Verbal task (F = 1.820, p = .185, η2p= .047) scores from the NEPSY-II. Conclusions: This is the first study to demonstrate that the neuropsychological domain of social cognition is impaired in DMD/BMD patients, independent of the level of general intelligence. Screening assessments in DMD/BMD patients should be promoted to allow social cognition difficulties to be detected at an early stage to enhance patients' quality of life and social development.

Abstract
Our study aimed to explore the intellectual function of patients with Duchenne muscular dystrophy (DMD) in China and examine the correlation of full-scale intelligence quotient (FSIQ) with age, mutation locations, mutation class, and dystrophin isoforms. We assessed 64 boys with DMD using The Wechsler Intelligence Scales for Children-Fourth Edition and compared intellectual function at enrollment and follow-up in the 15 patients who completed the follow-up. Our findings confirm that boys with DMD may exhibit cognitive impairment, with the Working Memory Index being the most impaired. There was no significant correlation between FSIQ and age; however, a positive correlation was noted between age and the Verbal Comprehension Index. FSIQ was not associated with mutation class, the number of affected mutated exons, or mutation locations. However, there was a significant difference in FSIQ between the groups with intact and deficient Dp140. Fifteen participants adhered to glucocorticoid therapy throughout the two-year follow-up period, and eleven of them showed an improvement in FSIQ compared to their initial scores, with improvement ranging from 2 to 20. In conclusion, patients with the cumulative loss of isoforms in the brain are at a higher risk of cognitive deficits and may require early cognitive interventions.

Abstract
Duchenne muscular dystrophy (DMD) is frequently associated with mild cognitive deficits. However, the underlying disrupted brain connectome and the neural basis remain unclear. In our current study, 38 first-episode, treatment-naive patients with DMD and 22 matched healthy controls (HC) were enrolled and received resting-sate functional magnetic resonance imaging scans. Voxel-based degree centrality (DC), seed-based functional connectivity (FC), and clinical correlation were performed. Relative to HC, DMD patients had lower height, full Intellectual Quotients (IQ), and IQ-verbal comprehension. Significant increment of DC of DMD patients were found in the left dorsolateral prefrontal cortex (DLPFC.L) and right dorsomedial prefrontal cortex (DMPFC.R), while decreased DC were found in right cerebellum posterior lobe (CPL.R), right precentral/postcentral gyrus (Pre/Postcentral G.R). DMD patients had stronger FC in CPL.R-bilateral lingual gyrus, Pre/Postcentral G.R-Insular, and DMPFC.R-Precuneus.R, had attenuated FC in DLPFC.L-Insular. These abnormally functional couplings were closely associated with the extent of cognitive impairment, suggested an over-activation of default mode network and executive control network, and a suppression of primary sensorimotor cortex and cerebellum-visual circuit. The findings collectively suggest the distributed brain connectome disturbances maybe a neuroimaging biomarker in DMD patients with mild cognitive impairment.

Abstract
The aim of the study was to retrospectively evaluate the consistency of longitudinal findings on intellectual functioning in DMD boys and their relationship to behavioral and neuropsychiatric difficulties. The cohort included 70 patients of age 3 to 17 years with at least two assessments using the Wechsler scales. CBCL and clinical observation of behavior were also performed. Changes in total intelligence quotient were interpreted as stable or not stable using the reliable-change method. On the first assessment 43/70 had normal quotients, 18 borderline, 5 mild, and 4 moderate intellectual disability, while 27/70 had no behavioral disorders, 17 had abnormal CBCL, and 26 patients had clear signs of attention deficits despite normal CBCL. The remaining seven were untestable. The mean total intelligence quotient change in the cohort was -2.99 points (SD: 12.29). Stable results on TIQ were found in 63% of the paired assessments. A third of the consecutive cognitive assessments showed a difference of more than 11 points with changes up to 42 points. Boys with no behavioral/attention disorder had smaller changes than those with attention (p = 0.007) and behavioral disorders (p = 0.002). Changes in IQ may occur in Duchenne and are likely to be associated with behavioral or attention deficits.

[PMID: 36421868 PMCID: PMC9688319 DOI: 10.3390/brainsci12111544] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 11/09/2022] [Accepted: 11/11/2022] [Indexed: 10/13/2023] Open
Abstract
BACKGROUND Intelligence scores in males with Duchenne Muscular Dystrophy (DMD) and Becker Muscular Dystrophy (BMD) remain a major issue in clinical practice. We performed a literature review and meta-analysis to further delineate the intellectual functioning of dystrophinopathies. METHOD Published, peer-reviewed articles assessing intelligence, using Wechsler Scales, of males with DMD or BMD were searched from 1960 to 2022. Meta-analysis with random-effects models was conducted, assessing weighted, mean effect sizes of full-scale IQ (FSIQ) scores relative to normative data (Mean = 100, Standard Deviation = 15). Post hoc we analysed differences between performance and verbal intelligence scores. RESULTS 43 studies were included, reporting data on 1472 males with dystrophinopathies; with FSIQ scores available for 1234 DMD (k = 32) and 101 BMD (k = 7). DMD males score, on average, one standard deviation below average (FSIQ = 84.76) and significantly lower than BMD (FSIQ = 92.11). Compared to a previous meta-analysis published in 2001, we find, on average, significantly higher FSIQ scores in DMD. CONCLUSION Males with Duchenne have, on average, significantly lower FSIQ scores than BMD males and the general population. Clinicians must consider lower intelligence in dystrophinopathies to ensure good clinical practice.

Abstract
OBJECTIVE We report neurodevelopmental manifestations in boys with Duchenne muscular dystrophy (DMD) and evaluate the correlations between mutation location and three neurodevelopmental abnormalities: intellectual disability, autism spectrum disorder, and attentional problems. METHODS This cross-sectional study included 55 Japanese boys with genetically confirmed DMD who visited the outpatient department of the National Center for Psychiatry and Neurology of Japan from October 2017 to April 2018. Neurodevelopmental manifestations were evaluated using the Raven's Colored Progressive Matrices (RCPM), the Parent-Interview Autism Spectrum Disorder Rating Scale-Text Revision (PARS-TR), and the Attention-Deficit Hyperactivity Disorder-Rating Scale. RESULTS Among the 55 boys (mean [standard deviation, SD] age, 9.5 [1.6] years), 24 (43.6%) scored below -2.0 SD in RCPM, indicating intellectual disability. Further, 83% had DMD variants in exon 45 or downstream to it (P = 0.005). On the PARS-TR, 30 (55%) and 21 boys (38%) scored higher than the clinical cutoff score in childhood and present scores, respectively. Stereotyped behavior and restricted interests scores were found to decrease with age (P = 0.003 and P = 0.01, respectively). DISCUSSION The results show that boys with DMD who have intellectual disability commonly have DMD variants in exon 45 or downstream to it. Stereotyped behavior and restricted interests improved with age, while intellectual disability did not. CONCLUSION Understanding these characteristics of neurodevelopmental disability may reduce risky behaviors and improve the overall quality of life of patients with DMD.

Abstract
Dystrophinopaties, e.g., Duchenne muscular dystrophy (DMD), Becker muscular dystrophy and X-linked dilated cardiomyopathy are inherited neuromuscular diseases, characterized by progressive muscular degeneration, which however associate with a significant impact on general system physiology. The more severe is the pathology and its diversified manifestations, the heavier are its effects on organs, systems, and tissues other than muscles (skeletal, cardiac and smooth muscles). All dystrophinopaties are characterized by mutations in a single gene located on the X chromosome encoding dystrophin (Dp427) and its shorter isoforms, but DMD is the most devasting: muscular degenerations manifests within the first 4 years of life, progressively affecting motility and other muscular functions, and leads to a fatal outcome between the 20s and 40s. To date, after years of studies on both DMD patients and animal models of the disease, it has been clearly demonstrated that a significant percentage of DMD patients are also afflicted by cognitive, neurological, and autonomic disorders, of varying degree of severity. The anatomical correlates underlying neural functional damages are established during embryonic development and the early stages of postnatal life, when brain circuits, sensory and motor connections are still maturing. The impact of the absence of Dp427 on the development, differentiation, and consolidation of specific cerebral circuits (hippocampus, cerebellum, prefrontal cortex, amygdala) is significant, and amplified by the frequent lack of one or more of its lower molecular mass isoforms. The most relevant aspect, which characterizes DMD-associated neurological disorders, is based on morpho-functional alterations of selective synaptic connections within the affected brain areas. This pathological feature correlates neurological conditions of DMD to other severe neurological disorders, such as schizophrenia, epilepsy and autistic spectrum disorders, among others. This review discusses the organization and the role of the dystrophin-dystroglycan complex in muscles and neurons, focusing on the neurological aspect of DMD and on the most relevant morphological and functional synaptic alterations, in both central and autonomic nervous systems, described in the pathology and its animal models.

Abstract
Duchenne muscular dystrophy is a highly progressive muscle wasting disorder due to primary abnormalities in one of the largest genes in the human genome, the DMD gene, which encodes various tissue-specific isoforms of the protein dystrophin. Although dystrophinopathies are classified as primary neuromuscular disorders, the body-wide abnormalities that are associated with this disorder and the occurrence of organ crosstalk suggest that a multi-systems pathophysiological view should be taken for a better overall understanding of the complex aetiology of X-linked muscular dystrophy. This article reviews the molecular and cellular effects of deficiency in dystrophin isoforms in relation to voluntary striated muscles, the cardio-respiratory system, the kidney, the liver, the gastrointestinal tract, the nervous system and the immune system. Based on the establishment of comprehensive biomarker signatures of X-linked muscular dystrophy using large-scale screening of both patient specimens and genetic animal models, this article also discusses the potential usefulness of novel disease markers for more inclusive approaches to differential diagnosis, prognosis and therapy monitoring that also take into account multi-systems aspects of dystrophinopathy. Current therapeutic approaches to combat muscular dystrophy are summarised.

Abstract
Introduction Cognitive difficulties and neuropsychological alterations in Duchenne and Becker muscular dystrophy (DMD, BMD) boys are not yet sufficiently explored, although this topic could have a relevant impact, finding novel biomarkers of disease both at genetics and neuroimaging point of view. The current study aims to: 1) analyze the neuropsychological profile of a group of DMD and BMD boys without cognitive impairment with an assessment of their executive functions; 2) explore the structural connectivity in DMD, BMD, and age-matched controls focusing on cortico-subcortical tracts that connect frontal cortex, basal ganglia, and cerebellum via the thalamus; 3) explore possible correlations between altered structural connectivity and clinical neuropsychological measures. Materials and methods This pilot study included 15 boys (5 DMD subjects, 5 BMD subjects, and 5 age-matched typically developing, TD). They were assessed using a neuropsychological assessment protocol including cognitive and executive functioning assessment and performed a 1.5T MRI brain exam including advance Diffusion Weighted Imaging (DWI) method for tractography. Structural connectivity measurements were extracted along three specific tracts: Cortico-Ponto-Cerebellar Tract (CPCT), Cerebellar-Thalamic Tract (CTT), and Superior Longitudinal Fasciculus (SLF). Cortical-Spinal Tract (CST) was selected for reference, as control tract. Results Regarding intellectual functioning, a major impairment in executive functions compared to the general intellectual functioning was observed both for DMD (mean score = 86.20; SD = 11.54) and for BMD children (mean score = 88; SD = 3.67). Mean FA resulted tendentially always lower in DMD compared to both BMD and TD groups for all the examined tracts. The differences in FA were statistically significant for the right CTT (DMD vs BMD, p = 0.002, and DMD vs TD, p = 0.0015) and the right CPCT (DMD vs TD, p = 0.008). Concerning DMD, significant correlations emerged between FA-R-CTT and intellectual quotients (FIQ, p = 0.044; ρs = 0.821), and executive functions (Denomination Total, p = 0.044, ρs = 0.821; Inhibition Total, p = 0.019, ρs = 0.900). BMD showed a significant correlation between FA-R-CPCT and working memory index (p = 0.007; ρs = 0.949). Discussion and conclusion In this pilot study, despite the limitation of sample size, the findings support the hypothesis of the involvement of a cerebellar-thalamo-cortical loop for the neuropsychological profile of DMD, as the CTT and the CPCT are involved in the network and the related brain structures are known to be implied in executive functions. Our results suggest that altered WM connectivity and reduced fibre organization in cerebellar tracts, probably due to the lack of dystrophin in the brain, may render less efficient some neuropsychological functions in children affected by dystrophinopathies. The wider multicentric study could help to better establish the role of cerebellar connectivity in neuropsychological profile for dystrophinopathies, identifying possible novel diagnostic and prognostic biomarkers.
