Perceptual problems in children and adults are typically misdiagnosed as other more common disabilities.
When a child has perceptual problems, their lack of language and speech is frequently attributed to other factors such as retardation, laziness, a lack of motivation, or a neuroses, etc.
This can happen to those of us at the other end of the age continuum too.
I mentioned earlier that on a good day (when I haven‰t been breathing too much bus fumes, or consuming too much lead from our water faucets or canned foods, or starving my neurons with the plethora of highly processed nutritionless foods that are on the market) I may loose 10,000 neurons a day. If I was lucky to be born with a hundred billion, I can go quite a few days with little effect. But if I had less to start with, and/or live long enough, in time there may be less neural structure to fully support these perceptual processes.
They will still function, but they may take increasingly longer to come reach a completion. Hence, I may find that life around me seems to grow more and more confusing.
