| Abstract |
The frequencies of pervasive developmental disorder (PDD) in Down's syndrome (DS) have been reported from 1% to 11%. However, it is not clear if the frequency of this co-occurrence is higher or lower than in other mental retardations. We study a large sample of DS population, finding a PDD frequency of 15.6%, with 5.58% of autism (eight males and two females) and 10.05% of PDD non autism (nine males and nine females. The meaning of this frequency is discussed. |

Attention Score in Context
This research output has an Altmetric Attention Score of 6. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 27 June 2014.
All research outputs
#6,090,818
of 23,867,274 outputs
Outputs from Journal of Autism and Developmental Disorders
#2,258
of 5,240 outputs
Outputs of similar age
#23,354
of 77,998 outputs
Outputs of similar age from Journal of Autism and Developmental Disorders
#6
of 10 outputs
Altmetric has tracked 23,867,274 research outputs across all sources so far. This one has received more attention than most of these and is in the 74th percentile.
So far Altmetric has tracked 5,240 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 13.2. This one has gotten more attention than average, scoring higher than 57% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 77,998 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 70% of its contemporaries.
We're also able to compare this research output to 10 others from the same source and published within six weeks on either side of this one. This one has scored higher than 4 of them.
