I haven't got a DAN doctor. We saw a good nutritionist who got us started.
The first step would be to try a Gluten free Casein Free diet. You can get urine tested form Sunderland university for £60 which will indicate whether your child will benefit from the diet. We also took put soy after reading that it can also have bad effects.
We started with simple good brand multivits and minerals and Cod Liver oil- make sure you get a mercury free brand.
We then got a hair analysis done that showed low levels of Zinc which we addressed with supplements. We have tried some supplements that have been very good and others that have had no noticeable effect. The best thing is to trial and take note of any changes.
We are on the waiting list for Dr Heard but I'm not sure we will see his replacement. we may go to Jean Mushcroft instead.
So far the positive effects we have seen in the last 9 months with Ds 2.10 ASD:
No longer sweats for England
Lost his red cheek and ears
Eye contact has improved loads
His diarrhoea has reduced loads he still gets some now and then.
concentration levels have improved.
No longer has a constant sticky eye
He used to always have a cough or cold
He used to regularly have long tantrums at the slightest thing Now he has a quick moan.
He no longer runs manically up and down the room.
He still has no spoken language although his understanding has improved somewhat.
He is still hard to engage and is in his own world a lot.
The Caudwell Trust can fund for supplements, tests and consultancy.
Do your research! There is an biomedical book called children with starving brain that gives a good overview and yahoo groups you can join where everyone can ask questions and discuss their experiences.
Biomedical is not exclusive and I believe can benefit other interventions such as ABA etc.
There is loads more info bit I don't want to go on too much so if you want any more info just say.
