Hi everyone, it's been a while since I posted, but I wanted to share some of what I learned from the neuropsychological testing. The testing psychologist's observations included "borderline deficits in visual attention and adaptive problem-solving, within the context of an otherwise average to well above average profiile". The visual test consisted of a written series of random numbers, and I was to circle all the 2's and 7's. At first, the test was not timed, and I did fairly well when I could go at my own pace. Then the test was repeated, but with a time limit that I could not meet -- in other words, I was rushed -- and I failed to see most of those 2's and 7's.
She then went on to note relative strengths, including verbal and visual memory, and working memory. It was very surprising to me that on some of the tests I felt I did well in, such as listening to "nonsense" words and then selecting the word I thought heard from a list, I actually scored poorly on. For instance, if the spoken word was "tasp", I heard "tast" (nonsense words). Conversely, I was very surprised that working memory was noted as a strength, although I have to wonder how I would have tested on another day when I wasn't so well-rested. She concluded that "subjective memory problems may be due to the above noted deficits in visual attention along with her hearing loss". So it seems the core functions are intact, but the brain is processing visual and auditory inputs incorrectly. Her recommendations included slowing down at work, less multi-tasking, and recording important meetings so that I can play them back later -- and if that's not possible, to find another job.
I also shared the test report with a psychiatrist who specializes in learning disorders, and he agreed with the notion that hearing and/or visual impairment can affect cognitive function. He also added vestibular loss to the list. He talked about "dichodic hearing", or hearing on both sides, and how losing one side can affect
everything -- emotions, cognitive function, and processing of visual and auditory inputs. He referred me to a DVD series called "Understanding The Brain" by Professor Jeanette Norden of Vanderbilt University, which explains all of this in great detail. (It's available through thegreatcourses.com -- pricey, but currently on sale! - I hope it's okay to mention that here.)
He went on to explain the role of sleep -- how the amount of energy the brain can store is minimal, so deep sleep becomes very important, because that's when the cortex recharges. And the 2nd phase of sleep (after the first four hours) is when memory is stored.
So what to make of all this information? And what can I do to help myself? Unilateral hearing is here to stay, at least until the next medical / technological breakthrough. Vestibular nerve -- severed -- although I have renewed my commitment to exercise, vestibular and otherwise. Vision -- the teary, blurry, AN-side eye -- now maybe that's something we can work with, and I have (finally!) found a neuro-opthamologist who seems very knowledgeable about AN (I quizzed him, haha!).
So finally -- confirmation that this isn't all in my head (or, actually, it is, but it's real). I'm working on my sleep habits. And the neuro-opthamologist believes he can help my teary eye. Maybe there's hope after all
I hope this isn't too much information, but I do hope that something I learned helps someone else.
