AIT has been in and out of favour with the USA American Speech Language hearing Association ASHA as to its affectiveness. At one point it was banned from use.
Rosalie Seymour (Ireland) works from the AIT Institute And yes I forgot it was Barard and not Alfred Tomatis.
But the main pint is that there is not cure of any of these issues, and we the UK Medical Research Council, USA ASHA and others are still trying to develop the technology to understand the real cause of these problems. And so none of these programs can claim to really fully understand how they work. Although like most other teaching processes world wide much is recommended on "What Works" The problems is none of these programs work for all and they can not say why.
And more important of all they do not know when these programs area actually causing harm.
It is all still very hit an miss as to if the program will provide any help for any child.
The biggest problem the lack of program specifications say link the pharmacutical industry which has to state how each drug can affect any user, the positives side effects,and possible harm. The programs which are sold or marketed without pointing out the possible limitations of what is on offer, and that a program might be trying to provide conflicting coping strategies to those already developed by a child or adult who has these problems.
Anadin works for headaches but not everyone can use it, and it also may depend on the cause of the headache
There was one program which in the 1990s was marketed as the cure for APD in the USA. It was and still is very expensive. There is no cure for APD. The program can provide great benefit for those who are able to benefit from it, but it can be very costly waste of money for those who gain no benefit what so ever, which can happen.
So the claims of "cure" and "rip off" abound the whole remedial program industry needs some sort of regulation to prevent this sort of miss information.
Unfortunately like the tabacco industry companies are very good at providing so called research evidence that their products work, mainly be not including the data of the less positive results, one way or another. This tactic is used by many education program providers as well, by not including those who do not complete a course, and not explaining why they were not able to complete a course. So the program can have 100% success with those who complete the course, but may be only an average of 60% of those who actually started the course.
