The three patients had moderate intellectual disability (IQ of <50), gross motor delay and a severe speech and language defect, characterised by a delay in the onset of speech, dysgrammatism and very poor speech articulation.
Women who were not able to fill out the personality inventories due to language problems, severe intelligence defects or mental illness were not included in the examination.
Dosage imbalance of more than 300 genes (Hattori et al., 2000) that are present on the extra copy of chromosome 21 results in a wide range of clinical features, including hypotonia, speech and language impairment, congenital heart defects, and craniofacial dysmorphology (Delabar et al., 2006).
Dyslexia represents a difficulty with reading, she says, not with thinking skills, one that "does not reflect an overall defect in language," but rather a weakness in a part of the language system.
In early life subjects may show expressive and/or receptive language deficits (e.g., significant delays in reaching normal language milestones), and may also exhibit fundamental defects in the ability to process rapidly changing acoustic information [ 2- 4].
These showed that unless the two tones were sufficiently separated in time, only one electrical signal, rather than two, was generated by the brains of the affected mice in response.In addition to defects in the language centres, a set of brain abnormalities has also been found in the visual pathways of dyslexics—smaller-than-normal cells in layers of the lateral geniculate nucleus.
Results were analyzed to determine the level of use and understanding in relation to the importance of periconceptional folic acid in the prevention of neural tube defects by primary language and educational level.
Frege noted this to be the main defect of natural language and a real obstacle to trying to formalize it (as opposed to just using the formal language without translation from natural language).
There were very few language translation problems; general question design defects and socio-cultural challenges to survey responses were more common.
