Background: Previous studies have reported a moderate influence of environmental factors in the aetiology of stuttering. However, psychological and socio-environmental factors in stuttering are often studied independently without exploring their relationships. This makes it difficult to know which factors are most important, especially among…

Objectives: Characterise the circumstances associated with death during admission of adults with Down syndrome (DS) and to identify predictors of mortality. Patients and Methods: Observational study based on data on all emergent admissions of adults with DS to hospitals of the Spanish National Health System between 1997 and 2014. We analysed…

Etiological beliefs of depression have differing impacts on motivation, hope, and treatment expectations. However, it is unclear where people are exposed to these beliefs. Objective: This study examined beliefs about depression and their relations to symptoms, attitudes about depression, and treatment preferences. Participants: 426 undergraduates…

Autism spectrum disorders (ASD) are strikingly more prevalent in males, but the molecular mechanisms responsible for ASD sex-differential risk are poorly understood. Abnormally shorter telomeres have been associated with autism. Examination of relative telomere lengths (RTL) among non-syndromic male (N = 14) and female (N = 10) children with…

Purpose: Down Syndrome Regression Disorder (DSRD) is a diagnosis of exclusion. Psychiatric and neuroimmunologic etiologies have been proposed although the exact etiology remains unknown. This study sought to review non-DSRD diagnoses at a large quaternary medical center specializing in the diagnosis of DSRD and compare clinical characteristics…

Background: Speech differences may occur between motor subtypes of Parkinson's disease (PD), but the literature remains limited. Aims: Examine speech characteristics in individuals with PD across the tremor-dominant, nontremor-dominant and mixed subtypes comparing to healthy controls. Methods and Procedures: A total of 115 individuals with PD were…

Bullying, a pernicious affliction that indiscriminately afflicts students of all ages and backgrounds, is a scourge that demands our attention. It involves a pattern of conduct whereby one individual is repeatedly targeted for aggression by one or more others, often due to a power imbalance. In response to this pressing issue, the present study…

The purely descriptive definition of autism introduced by the DSM III in 1980 marked a departure from previous DSM editions, which mixed phenomenological descriptions with psychoanalytic theories of etiology. This provided a blank slate upon which a variety of novel theories emerged to conceptualize autism and its treatment in the following four…

Background: Recent evidence suggests that speech substantially changes in ageing. As a complex neurophysiological process, it can accurately reflect changes in the motor and cognitive systems underpinning human speech. Since healthy ageing is not always easily discriminable from early stages of dementia based on cognitive and behavioural…

Whether altered white matter microstructural property of autistic people also exists in non-autistic siblings is uncertain. The microstructures of a neural tract may not be consistent throughout the whole track. We assessed 38 cognitive-able autistic males (aged 15.8 ± 4.4 years), 39 non-autistic siblings (16.5 ± 5.7 years), and 78 age- and…

Background: Service providers' knowledge and attitude of people with disabilities is the foundation for inclusion. This qualitative study explored awareness and intervention beliefs of intellectual disability in 106 teachers and 170 preservice students in Kuwait. Method: After reading an unlabelled vignette about a young man with an intellectual…

Introduction: Childhood visual impairment is a global concern. We aimed to identify the major causes of childhood visual impairment in schools for students with visual impairments in Tehran, Iran. Methods: This cross-sectional study was conducted on students attending two schools for students with visual impairments in Tehran. All students or…

Blaming teachers and schools for perceived or actual educational failures are popular tropes for justifying educational reforms in the United States. Critical educational research implicates neoliberalism in the normalized positioning of teachers and schools as the key suspects in educational failures. This article critiques the etiology of…

Individuals living with intellectual disability can have multiple co-occurring medical conditions including associated genetic diagnoses. The number of genetic etiologies associated with ID is growing, with some quite new and rare, and others more common and associated with what is often considered a syndrome. In the context of genetic etiologies…

Background: Aggressive behaviour is prevalent in people with intellectual disabilities. To understand the aetiology, it is important to recognize factors associated with the behaviour. Method: A systematic review was conducted and included studies published between January 2002 and April 2017 on the association of behavioural, psychiatric and…
