Long-term memory loss
If your memory problems extend to things that happened years or decades in the past, it’s possible you might be dealing with a different type of dementia, says Dr. Wasserman. “For people with Alzheimer’s, long-term memory tends to hold out, but with other forms of dementia you may have more long-term memory issues.”
Multi-infarct dementia—caused by multiple strokes, which interrupt blood supply resulting in damaged brain tissue—is probably the best example because the strokes may hit part of brain responsible for long-term memory, he explains.
