Post A single stroke can mimic DLB
This is the case of an Italian woman who was thought to have DLB due to parkinsonism, hallucinations, fluctuating cognition, and dementia. All the neuropsychological testing pointed to DLB. After an MRI was done, evidence of vascular disease and a large stroke were found. The diagnosis was changed to "single strategic infarct dementia."

The authors state: "To our knowledge, this SSID is the first described mimicking a DLB. We think it is extremely interesting because it confirms the growing evidence in the literature that lesions in the posterofrontal circuitry, which is involved in the integration of visual information and motor reaction, are responsible for cognitive and behavioral deficiencies in DLB."

Robin, do you think such a thing might have shown up on a CT scan, as well? I wonder, because Derek had one a couple of years ago because of increased confusion, Capgras and disorientation and nothing showed up but a sinus infection. No MRI was done.

I've always wondered because he has a strong family hx of CVA.

Pat [68] married to Derek [84] for 38 years; husband dx PDD/LBD 2005, probably began 2002 or earlier; late stage and in a SNF as of January 2011. Hospitalized 11/2/2013 and discharged to home Hospice. Passed away at home on 11/9/2013.

I don't think CTs are as helpful as MRIs are in seeing signs of stroke.
