Williams syndrome (WS) is a genetic disorder characterized by intellectual delay and an affinity for music.
"We found out that children exposed to sodium valproate were at a greater risk of intellectual delay, memory problems, language difficulties and behavioural problems".
Such tests should control for comorbid conditions such as intellectual delay, attention-deficit/hyperactivity disorder, and reduced inner speech.
Such information is critical for identifying atypical brain development believed to be associated with a growing number of neuropsychiatric disorders [Courchesne et al., 2007; Just et al., 2012], as well as providing a developmental basis for learning, language, or intellectual delay [Trauner et al., 2000].
Lead, too, was for years thought to be safe in small doses, until further study demonstrated that, particularly for children, even slight exposure could result in intellectual delays, hearing loss, and hyperactivity.
Well, first, those with DCD may have average to above-average intelligence, yet intellectual delays are often what providers are looking for as the cardinal signal of developmental disorders.
Among them were three patients with Cornelia de Lange syndrome, which can cause intellectual delays and distinctive facial features such as long, thick eyebrows and downturned lips (above).
Youth in the Autism spectrum are more likely to be brought to psychiatric facilities to treat externalizing behaviors and aggression, intellectual delays affecting motor, feeding, or late onset of developmentally appropriate self-care functions or epilepsy.
Levels of lead exposure previously thought to be safe or inconsequential for children have consistently been shown to be risk factors for reading problems, intellectual delays, school failure, attention deficit hyperactivity disorder, and antisocial behaviors (Bellinger 2004; Braun et al. 2006; Burns et al. 1999; Dietrich et al. 2001; Needleman et al. 1990 , 1996.
Some have suggested that maternal smoking during pregnancy can lead to intellectual delays, most likely caused by central nervous system impairment (Olds et al. 1994), or can negatively affect language ability through underlying physiologic mechanisms (e.g., outer hair cells in the ear), thus leading to poorer performance on language-related tasks (McCartney et al. 1994).
To assess differences between child age at first parental concern and age at first parental discussion of concerns with a health care provider among children with autism spectrum disorder (ASD) vs those with intellectual disability/developmental delay (ID/DD), and to assess whether provider response to parental concerns is associated with delays in ASD diagnosis.
