All of your sensory systems are connected. They all go to the same place, in the end. Working on your processing capabilities in one sensory system is bound to help other in most cases.

There are some connections that are even stronger than others. For instance, the connection between your vestibular sense and your auditory and visual senses is far more linked than... say... your olfactory and tactile systems may be.

Since your major issues are found in the auditory and vestibular senses, I would recommend one treatment that is designed specifically for those two senses. It's called Listening Therapy, and it comes in a few forms. The one I've been using is called SAMONAS. Basically, it involves listening to specially altered CDs at a relatively low volume through large ear muff style headphones. The CDs are designed to send ultra high frequencies to your brain that you are incapable of hearing, but that are registered by your brain. Listening to these CDs 30 minutes a day (or whatever your OT perscribes) will dig directly into your vestibular system, to begin working on that, and, in turn, will also help to treat your auditory issues.

I can't say it's caused night and day differences for me, but it has helped quite a bit. For many though, it's just what they needed to set things pretty straight in their brain. Either way, it's definitely worth looking into. But of course, would require an OT... Anyway, hope this is helpful .
