Mild neurocognitive disorder due to unknown etiology

I have had two batteries over two years of neuropsych testing and the persistent assessment is ‘mild neurocognitive disorder due to unknown etiology, but not felt to be consistent with Alzheimer’s disease’.

The only area of testing where I had difficulty were visual-spatial tasks (discrimination, drawing, visual memory). When copying a detailed figure, my drawing was missing multiple components and was distorted.
There was no evidence of difficulties with verbal learning or memory.

I had two bizarre episodes in 2024. Abruptly my visual field shifted 90 degrees and lasted anout 30-45 seconds. . I was NOT DIZZY , in spite of doc saying ‘oh thats vestibular - not uncommon in geriatrics’. SO off I go to ENT - where they were unable to produce any vestibular reaction to postural changes. The ophthalmologist said he would send me to Duke if it happened again. But it has not

It’s a mystery!!

The only thing relevant in my MRI was small chronic white matter infarcts. My ATN indicates Alzheimer’s pathology on board. I have one instance of ETOH4.

Does anyone have anything similar?? I am trying to get in as a new patient to the Duke/UNC Neurology lab but fear i am just another old lady whose brain doesn't work as well as it once did.
