I have been diagnosed by three neurologists of having vascular dementia i had to see a fourth neurologist 2 days ago and he informed me that i did not have vascular dementia. he had me close my eyes and looked at my hands. but he did not have any tes?

You have made some statements but asked no clear question. I would be imprudent to comment about other physicians assessment of your condition without a full review of all the case information including exam ant test results. Find a neurologist who will explain to you what their testing shows and how it relates to you. If you keep doctor shopping you are bound to get some varied opinions.

If you possess cognitive or intellectual adverse changes, you would be classified as having a dementia, and the specific variety should be confirmed. Hard to understand why you have now seen 4 neurologists. Resolve the discrepancies by visiting a medical school neurology department.
