I was disoriented for about 20 seconds while driving close
An MRI and Neurologist visit is recommended.
Hello dear, welcome to Ask a doctor service.
I read your query and here is my advice.
I don't think this is something related to a disease. If it is a very rare episode it can happen to everyone especially to people your age.
During aging the brain changes causing these episodes in the absence of neurodegenerative disease or the neuropsychological profile of healthy older adults.
In this scenario, you should visit a Neurologist and do an MRI to role out neurodegenerative diseases such as dementia, mild cognitive impairment, Alzheimer etc.
Hope I have answered the question.
Let me know if I can assist you further.
