Developmental language disorder (DLD) is a neurodevelopmental disorder primarily affecting language in the absence of a known biomedical condition, which may have a large impact on a person's life and mental health. Family-based studies indicate a strong genetic component in DLD, but genetic studies of DLD are scarce. In this study we estimated the heritability of DLD and its genetic correlations with related disorders and traits in sample of >25,000 individuals from the Danish Blood Donor Study for whom we had both genotype data and questionnaire data on language disorder and language support.

The aim of this study was to investigate listening and processing skills in a clinical sample of 7-to-10-year-old children diagnosed with DPD in their preschool years and compare these to same-aged typically developing (TD) children. The Evaluation of Children's Listening and Processing Skills (ECLiPS) was completed by parents of 115 children with DPD and by parents of 46 TD children.

There is a lack of studies to understand the whole genetic spectrum in individuals with DLD. Previously, we recruited 61 probands with severe DLD from 59 families and examined 59 of them and their families using microarray genotyping with a 6.

- Developmental language disorder (DLD) affects language abilities and has a significant impact on daily functioning, without being linked to other medical conditions, and is often overlooked even by healthcare professionals.
- In a large study involving over 46,000 participants, DLD prevalence was found to be between 3.36%-3.70% based on self-reports, significantly higher than the 0.04% found in hospital records, highlighting a serious issue of underdiagnosis.
- The research also revealed a connection between DLD and various difficulties in reading and learning, as well as poorer mental and physical health, indicating long-term implications, while genetic analysis suggested greater complexity in the disorder's hereditary factors.

Aim: The aim of the study was to explore the assessment fidelity of a language screening instrument for four-year-old children. is a mandatory part of the healthcare program within the Swedish Child Health Service (CHS) and is offered to all four-year-olds in the region Scania in Sweden.
Methods: The study was based on structured observations of twenty-four specialist CHS nurses' adherence to the protocol during screening.
