Semantic pragmatic disorder - could anyone explain?

[GreenPetalsForChristmas]

I have ds who nearly 8yo. There is something not quite right (Starting with big meltdowns/outbursts of anger at home) but I can't quite managed to put my finger on it.

I have considered AS but if it was it would be very mild. He certainly doesn't look 'quirky' enough if that makes sense (Hope I am not offending anyone here. Just don't now how else to put it).

However I have come across the semantic pragmatic disorder and from what I have read so far, he seems to be fitting the criteria much better.

Does anyone has some experience of it or has any links/books they could recommend to explain better what it is about? What I have found so far feels flaky and limited and I don't want to start harping on about something like this if I have completely misunderstood what it is about.

Your DS sounds as if he may be somewhere inbetween DS1 (12) (ASD, ADD, APD, SpLD and some more) and DS2 (6) (Language delay (pronounciation and narrative skills etc), SLCN, hypermobility, sensory processing disorder, significant difference between single word understanding (99th percentile) and sentence comprehension (25th percentile).

DS2 is getting input from school because of the speech problems and because his social understanding/pragmatic understanding causes a problem to them - disrupts the learning of others. DS1 had no input from school as he internalises anxiety. Actually DS1 developed far greater needs as he got older and is currently not able to attend school and we are going to tribunal for independent ss. DS1's diagnoses all came from independent assessment. DS1 has meltdowns but DS2 does not. For all their similarities they are very different - both on the spectrum (DS2 not officially diagnosed yet) but very different from each other and neither of them are the same as friends' children with ASD or obviously display what I assumed typical ASD behaviour would look like. DS1 in particular because of no speech delay can 'pass for normal'.

I don't want to give a pop diagnosis but you have expressed sufficient concerns to warrant further investigation if they remain or have increased as a result of posting here.
