Short Report: Where do caregivers of persons with intellectual or developmental disabilities obtain information about medication?

BACKGROUND/AIMS/METHODS: Medication information is available from many sources. This short report provides a simple description of where caregivers of people with intellectual/developmental disability (IDD) obtain medication information, and compares these sources between family caregivers and direct support professionals (DSP). PROCEDURES/OUTCOMES: Cross-sectional study design using an internet-based survey of caregivers, aged 18 years or older, who provided support to adults with IDD. The primary outcome is the source of medication information reported by caregivers. RESULTS/CONCLUSIONS: Eighty-nine caregivers responded. Health care professionals were the primary source (87.6 %) of medication information, followed by the internet (77.5 %). There was no difference between caregiver groups for these two sources. The prescription label/information sheet was the next most common source (56.2 %), with significantly more family (76.2 %) versus DSP (38.3 %), p < 0.001. A medication reference was also common (43.8 %), with 28.6 % of family and 57.4 % of DSP, p = 0.006. House manager/nurse was next, with 16.9 %, and television/radio as a source (10.1 %), no difference between groups. Lastly, friends or coworkers were 7.9 %, with no DSP endorsing this option, p = 0.006. IMPLICATIONS: Caregivers obtain medication information from a variety of sources, with health care professionals being the primary source. The internet was also very common, which may be worrisome, due to the wide range of level of quality of information available. Educational interventions should be developed to provide caregivers with tools to be able identify and use legitimate medication information.

Acute ischemic strokes in patients with developmental disabilities: A cross-sectional analysis.

OBJECTIVE: Patients with developmental disabilities (DD) are frequently excluded from acute ischemic stroke (AIS) randomized control trials. We sought to evaluate the impact of having DD on this patient cohort. METHODS: The National Inpatient Sample was analyzed to explore the impact of AIS and treatment on discharge dispositions in patients with DD. Clinical characteristics, treatments, and outcomes were compared to fully-abled patients with AIS. RESULTS: 1,605,723 patients with AIS were identified from 2010-2019, of whom 4094 (0.30%) had a DD. AIS patients with DD were younger (60.31 vs 70.93 years, p < 0.01), less likely to be Caucasian (66.37%vs 68.09%, p = 0.01), and had higher AIS severity (0.63 vs 0.58, p < 0.01). Tissue plasminogen activator (tPA) was administered in 99,739 (6.2%) fully-abled patients and 196 (4.79%) of patients with DD (p < 0.01). Endovascular thrombectomy (EVT) was performed in 21,066 (1.31%) of fully-abled patients and 35 (0.85%) of patients with DD (p < 0.01). The presence of developmental disabilities were predictive of lower rates of tPA (OR:0.71,CI:0.56-0.87,p < 0.01) and EVT (OR:0.24,CI:0.16-0.36,p < 0.01). In a propensity score-matched cohort of all AIS patients who underwent EVT, there was no difference in functional outcome (p = 0.41), in-hospital mortality (0.10), and LOS (p = 0.79). CONCLUSION: AIS patients with DD were less likely to receive tPA and EVT compared to fully-abled patients. Individuals with DD had higher mortality and worse discharge disposition. There was no significant difference in post-EVT outcomes between fully-abled patients and patients with developmental disabilities. In the absence of prospective clinical trials, population based cross-sectional analyses such as the present study provide valuable clinical insight.

Factors associated with use of medication for behavioral challenges in adults with intellectual and developmental disability.

BACKGROUND/AIMS: Persons with intellectual or developmental disabilities and who exhibit challenging behaviors are often prescribed medication to control behavior. Little is known about the environmental factors that may be associated with taking these medications. METHODS AND OUTCOMES: This study examined the association between individual and intermediate or environmental factors and the documented use of medication for clients with intellectual or developmental disabilities (IDD) who exhibit challenging behavior, using the 2014-15 National Core Indicators Adult Consumer Survey dataset. RESULTS AND CONCLUSIONS: Individual-level variables associated with a higher likelihood of taking medication for persons with IDD exhibiting challenging behaviors included being of younger age, male gender, having moderate or severe intellectual disability, being ambulatory, communicating verbally, having a behavioral plan, requiring support for behavioral challenges, and having a history of mental illness. Environment-level variables included infrequently eating out and having less everyday choice. This study found that restrictions in opportunities to make choices in their life was associated with a greater likelihood of being on a medication for persons with IDD who exhibit challenging behavior. Living in group home settings also increased the likelihood of medication use. A limitation of the study is a lack of information on why medications were prescribed and whether they were intended to treat the challenging behavior. IMPLICATIONS: This work has important implications for health providers, as addressing malleable social factors may provide an avenue for reducing challenging behaviors without the need for medication.

Factors contributing to antihypertensive medication adherence among adults with intellectual and developmental disability.

Adults with intellectual or developmental disabilities often have hypertension and mental illness, and are prescribed medications for treatment. This study examined psychotropic medication adherence as a mediator between the association of residence type and antihypertensive medication adherence for adults with intellectual or developmental disabilities. We used Medicaid data of adults with intellectual or developmental disabilities who had hypertension and prescribed antihypertensive medication (N = 1,201) to measure the direct effect, indirect effect, and total effect of residence type (home vs. supervised setting) and antihypertensive medication adherence, with a mediator of psychotropic medication adherence. The indirect effect of psychotropic medication adherence on antihypertensive medication adherence was 1.26 (OR = 1.26, CI: 1.08-1.52), holding residency constant. The direct effect of residential type on antihypertensive medication adherence was 3.75 (OR = 3.75, CI: 1.61-8.75). This association may be due to some features of having a mental illness or maybe the result of being prescribed more than one medication.

Psychiatric Presentations and Medication Use in Older Adults With Intellectual and Developmental Disabilities.

OBJECTIVE: Adults with intellectual and developmental disabilities (IDD) are living longer, yet research about the medical and psychiatric needs of older adults still lags behind that of younger individuals with IDD. The aim of this study was to assess age-related differences in the mental health presentations of adults with IDD. METHODS: Fully deidentified data for adults 30 years and older were extracted from the START (Systemic, Therapeutic, Assessment, Resources, and Treatment) Information Reporting System, a deidentified database housed at the Center for START Services. Caregivers and START team documents reported psychiatric diagnoses, service use, recent stressors, and challenging behaviors. t Tests, Mann Whitney U tests, χ2 tests, and multinominal logistic regression models were used to compare the two age groups, 30-49 years (n = 1,188) versus 50 years and older (n = 464). RESULTS: Older adults had more medical conditions, fewer reported psychiatric conditions, and were more likely to be taking more psychiatric medications compared to younger adults, after adjusting for demographic variables, disability level, and number of recent stressors. CONCLUSION: Although older individuals reported fewer psychiatric diagnoses, they were more likely to take higher numbers of psychiatric medications and have more medical conditions. Clinicians and researchers ought to devote more attention to the healthcare needs of older adults with IDD, a vulnerable group exposed to polypharmacy and at risk of adverse events.

A case of treatable encephalopathy, developmental regression, and proximal tremor.

Tyrosine hydroxylase (TH) deficiency is an autosomal recessive condition first described as a progressive, early-onset hypokinetic-rigid and dystonic syndrome that was responsive to levodopa. Here we present a child with developmental regression, proximal tremor, and encephalopathy found to have tyrosine hydroxylase deficiency in whom treatment resulted in acquisition of developmental milestones.

The neuropathological findings of developmental and epileptic encephalopathy-43 (DEE43) and delineation of a the molecular spectrum of novel case.

Developmental and epileptic encephalopathies (DEE) constitute an expanding group of severely disabling and, most frequently, drug-resistant disorders starting in the first year of life. Among them, there is DEE43, caused by dominant mutations in the GABRB3 gene. We present first neuropathological findings in a novel, molecularly confirmed case with the fatal course. The neuropathological analysis revealed co-existing developmental anomalies and retardation of myelination resulting from disturbed early brain growth as well as lesions caused by epileptic hypoxic-ischemic episodes. Developmental anomalies included misplaced neurons in the cerebellar white matter, heterotopic neurons in the cortical molecular layer and in the molecular layer of the hippocampal dentate gyrus, dysmorphic cerebellar dentate nuclei and inferior olivary nuclei in the medulla oblongata. The migrational and maturational disorders leading to the neuronal network dysfunction could be the cause of both the lack of development and the ineffectiveness of antiepileptic treatment in children affected by DEE. Giving the presented neuropathological description and based on the literature, we discuss the pathomechanism of the disease, to improve current understanding of both the lack of development and the ineffectiveness of treatment of affected children.

Expanding the phenotype: Four new cases and hope for treatment in Bachmann-Bupp syndrome.

Bachmann-Bupp syndrome (BABS) is a rare syndrome caused by gain-of-function variants in the C-terminus of ornithine decarboxylase (ODC coded by the ODC1 gene). BABS is characterized by developmental delay, macrocephaly, macrosomia, and an unusual pattern of non-congenital alopecia. Recent diagnosis of four more BABS patients provides further characterization of the phenotype of this syndrome including late-onset seizures in the oldest reported patient at 23 years of age, representing the first report for this phenotype in BABS. Neuroimaging abnormalities continue to be an inconsistent feature of the syndrome. This may be related to the yet unknown impact of ODC/polyamine dysregulation on the developing brain in this syndrome. Variants continue to cluster, providing support to a universal biochemical mechanism related to elevated ODC protein, enzyme activity, and abnormalities in polyamine levels. Recommendations for medical management can now be suggested as well as the potential for targeted molecular or metabolic testing when encountering this unique phenotype. The natural history of this syndrome will evolve with difluoromethylornithine (DFMO) therapy and raise new questions for further study and understanding.

Surgery versus botulinum neurotoxin A to reduce drooling and improve daily life for children with neurodevelopmental disabilities: a randomized controlled trial.

AIM: To compare the effect of bilateral submandibular duct ligation and botulinum neurotoxin A (BoNT-A) on drooling severity and its impact on daily life and care in children and adolescents with moderate-to-severe drooling. METHOD: This was a randomized, interventional, controlled trial in which 53 children and adolescents (31 males, 22 females, mean age 11y, range 8-22y, SD 2y 10mo) with cerebral palsy (58.5%) or other non-progressive developmental disorders (41.5%) were randomized to BoNT-A (n=26) or bilateral submandibular duct ligation (n=27). A parent questionnaire on the severity of drooling in specific positions and daily activities and the impact of drooling on daily life and care was filled out at baseline and 8 and 32 weeks posttreatment. RESULTS: Both BoNT-A and bilateral submandibular duct ligation had a positive effect on daily care, damage to electronic equipment and/or furniture, social interactions, and self-esteem. However, bilateral submandibular duct ligation had a significant greater and longer-lasting short- (8wks) and medium-term (32wks) effect on daily care, reducing damage to electronic devices, and improving social interactions and satisfaction with life in general. INTERPRETATION: This randomized controlled trial confirms reduced drooling by both BoNT-A and bilateral submandibular duct ligation, but provides new evidence on improved well-being through a reduction in drooling. Even though there is a greater risk of complications and morbidity after bilateral submandibular duct ligation, compared to BoNT-A there was a significantly greater and longer-lasting positive effect on most outcomes. What this paper adds Bilateral botulinum neurotoxin A (BoNT-A) and submandibular duct ligation had a positive effect on the well-being of individuals with moderate-to-severe drooling. Bilateral submandibular duct ligation had a greater effect on the impact of drooling during daily care than BoNT-A. Bilateral submandibular duct ligation reduced damage to electronic devices and improved social interactions and satisfaction with life.

Expanding the spectrum of endocrinopathies identified in Schaaf-Yang syndrome - A case report and review of the literature.

Schaaf-Yang syndrome is a genetic disorder caused by mutations in the paternal allele of the MAGEL2 gene. Developmental delay, feeding difficulties, joint contractures and a high prevalence of autism spectrum disorders are characteristic of the syndrome. Endocrine abnormalities include mostly various pituitary hormonal deficiencies, presenting as hypoglycemia in 48% of reported cases. Persistent hyperinsulinism was only described in two siblings and responded to diazoxide treatment. We describe a unique case of an infant with Schaaf-Yang syndrome that presented with persistent hyperinsulinism unresponsive to diazoxide. Furthermore, we conducted a literature review of the endocrine abnormalities described in MAGEL2 related disorders. The case presented expands the clinical phenotype of Schaaf-Yang syndrome and emphasizes the importance of endocrine follow-up in these patients. Further investigation into the role of MAGEL2 in the regulation of pancreatic beta-cell insulin secretion, will improve our understanding of the abnormalities in glucose regulation in this syndrome.

Psychotropic Use Among Youths With Intellectual and Developmental Disabilities.

OBJECTIVE: The authors examined the prevalence and correlates of psychotropic medication prescribing among outpatient youths with intellectual and developmental disabilities. METHODS: The authors reviewed cross-sectional data on medications for 1,333 youths (ages 5-21 years) with intellectual and developmental disabilities who were referred to a community-based mental health crisis service. Descriptive statistics and regression analysis were used to describe the study group and to identify correlates of psychotropic polypharmacy, antipsychotic use, and anticonvulsant use in the absence of a seizure disorder. RESULTS: Most youths were taking psychotropic medications (N=1,139, 86%), often three or more medications (N=733, 55%) from two or more drug classes (N=919, 69%). Most youths received antipsychotics (N=863, 65%), and a third (N=432, 32%) were taking anticonvulsants in the absence of a seizure disorder. Greater severity (number of psychiatric diagnoses and recent psychiatric hospitalization), older age, and living in a group home were significantly correlated with these practices. CONCLUSIONS: Polypharmacy, antipsychotic use, and anticonvulsant use in the absence of seizure disorders were common among youths with intellectual and developmental disabilities referred to the crisis service. Older age, number of psychiatric diagnoses, living in a group home, and psychiatric hospitalization correlate with these prescribing practices. These elevated prescribing rates in a very vulnerable population warrant further study.

The Use of Psychotropic Medication in Iranian Children with Developmental Disabilities.

The use of psychotropic medication in children is increasing worldwide. Children with developmental disabilities seem to be prescribed these medications at a higher rate compared to their non-disabled peers. Little is known about prescribing in non-Western, middle-income studies. In Iran, the file records of 1133 children, aged 2 to 17 years, assessed as having autism spectrum disorder (ASD) or an intellectual disability (ID) in Tehran City and Province from 2005 to 2019 were collated, and information from parental reports of medications was extracted. Upwards of 80% of children with ASD and 56% of those with ID were prescribed a psychotropic medication with around one quarter in each group taking two or more medications. The rates were higher among male children showing difficult-to-manage behaviors such as hyperactivity, but less so for children of fathers with higher levels of education. The lack of alternative management strategies may be a significant driver for the use of psychotropic medications in Iran and other Low and Middle Income countries, despite their known side effects, and their failure to address the developmental needs of the children. Rather, multi-disciplinary, behavioral, therapeutic, and educational interventions are required, but these are not available widely in Iran, although a start has been made.

Treatment efficacy of high-dose creatine supplementation in a child with creatine transporter (SLC6A8) deficiency.

BACKGROUND: Creatine transporter deficiency is an inborn error of metabolism caused by a deficiency in the creatine transporter protein encoded by the SLC6A8 gene. Previous treatment with creatine supplementation, either alone or in combination with creatine precursors (arginine or glycine), has been attempted; the efficacy of therapy, however, remains controversial. METHODS AND RESULTS: To analyze the treatment efficacy of high-dose creatine supplementation on creatine transporter deficiency, we reported a child diagnosed with creatine transporter deficiency, who was treated with a conventional dose of creatine (400 mg/kg/d) for 1 month, then twice the dose (800 mg/kg/d) for 2 months, and finally 3 times the dose (1200 mg/kg/d) for 3 months. The patient tolerated the treatment well and showed improvements in muscle mass and strength when the creatine dose was gradually increased to 1200 mg/kg/d. However, when assessed by proton magnetic resonance spectroscopy (H-MRS), the brain creatine concentration did not increase, and there was no improvement in speech and neurodevelopmental symptoms. CONCLUSION: We conclude that high-dose creatine supplementation (1200 mg/kg/d) alone improved muscular symptoms, but did not improve cognitive symptoms and brain creatine concentration assessed using H-MRS. Therefore, new treatment strategies are required for the management of creatine transporter deficiency.

Enzyme Replacement Therapy for Succinic Semialdehyde Dehydrogenase Deficiency: Relevance in γ-Aminobutyric Acid Plasticity.

Succinic semialdehyde dehydrogenase deficiency (SSADHD) is a rare inborn metabolic disorder caused by the functional impairment of SSADH (encoded by the ALDH5A1 gene), an enzyme essential for metabolism of the inhibitory neurotransmitter γ-aminobutyric acid (GABA). In SSADHD, pathologic accumulation of GABA and its metabolite γ-hydroxybutyrate (GHB) results in broad spectrum encephalopathy including developmental delay, ataxia, seizures, and a heightened risk of sudden unexpected death in epilepsy (SUDEP). Proof-of-concept systemic SSADH restoration via enzyme replacement therapy increased survival of SSADH knockout mice, suggesting that SSADH restoration might be a viable intervention for SSADHD. However, before testing enzyme replacement therapy or gene therapy in patients, we must consider its safety and feasibility in the context of early brain development and unique SSADHD pathophysiology. Specifically, a profound use-dependent downregulation of GABAA receptors in SSADHD indicates a risk that any sudden SSADH restoration might diminish GABAergic tone and provoke seizures. In addition, the tight developmental regulation of GABA circuit plasticity might limit the age window when SSADH restoration is accomplished safely. Moreover, given SSADH expressions are cell type-specific, targeted instead of global restoration might be necessary. We therefore describe 3 key parameters for the clinical readiness of SSADH restoration: (1) rate, (2) timing, and (3) cell type specificity. Our work focuses on the construction of a novel SSADHD mouse model that allows "on-demand" SSADH restoration for the systematic investigation of these key parameters. We aim to understand the impacts of specific SSADH restoration protocols on brain physiology, accelerating bench-to-bedside development of enzyme replacement therapy or gene therapy for SSADHD patients.

Hemolysis and Neurologic Impairment in PAMI Syndrome: Novel Characteristics of an Elusive Disease.

PSTPIP1-associated myeloid-related proteinemia inflammatory (PAMI) syndrome is a rare early-onset autoinflammatory disease associated with various hematologic findings, including chronic neutropenia and pancytopenia. We report a unique case of PAMI syndrome in a toddler with transfusion-dependent hemolytic anemia, hepatosplenomegaly, failure to thrive, developmental delay, and multiple malformations. Because of acute inflammatory-driven decompensation, anakinra was started with dramatic improvement of both the hematologic and neurologic involvement. A customized next-generation sequencing panel later identified a de novo pathogenic variant in the PSTPIP1 gene, confirming the diagnosis. Our case illustrates the broad spectrum of phenotypes associated with PAMI syndrome, which should be considered in any case of unexplained cytopenias associated with autoinflammatory stigmata. It is also one of the few reports of neurologic involvement in PSTPIP1-associated inflammatory diseases. Increased awareness of this rare disease and early performance of genetic testing can correctly diagnose PAMI syndrome and prevent disease complications.

Uridine-responsive epileptic encephalopathy due to inherited variants in CAD: A Tale of Two Siblings.

We report two siblings with intractable epilepsy, developmental regression, and progressive cerebellar atrophy due to biallelic variants in the gene CAD. For the affected girl, uridine started at age 5 resulted in dramatic improvements in seizure control and development, cessation of cerebellar atrophy, and resolution of hematological abnormalities. Her older brother had a more severe course and only modest response to uridine started at 14 years old. Treatment of this progressive condition via uridine supplementation provides an example of precision diagnosis and treatment using clear outcome measures and biomarkers to monitor efficacy.

Neurodevelopmental disorders (NDD) are characterized by disturbances of the formation of cognitive functions, communication skills, behavior characteristics and/or motor skills, which are caused by abnormalities in the course of the processes of neuroontogenesis. In the clinical practice of a pediatric neurologist and pediatrician, a significant part consists of patients with NDD without a general decrease in intelligence, primarily with speech development disorders, attention deficit hyperactivity disorder (ADHD), specific learning disorders (dyslexia, dysgraphia, dyscalculia). NDD represent a heterogeneous group of diseases, having multifactorial origin and a neurobiological nature, which are caused by genetic mechanisms and early (perinatal) brain damage. Among children with NDD, there is a higher occurrence of anxiety disorders compared to their peers. With NDD, early intervention is indicated, and its positive effect is possible during the period when the brain is most plastic and capable of changes. The published results of multicenter, double-blind, placebo-controlled, randomized clinical trials of pharmacotherapy with the medication "Tenoten for children" for ADHD, specific learning disorders, anxiety disorders and the consequences of perinatal damage to the central nervous system are reviewed.
