My husbands 84 yr old grandmother now has dementia. From what I'm reading, there is no cure and not much hope of slowing it down. Her doc has already prescribed meds for the anxiety/ocd and for the "daytime agitation" to control some of the symptoms and make it easier for us. He has suggested maybe having a CAT scan done to see if it is from mini stokes. If nothing more can be done than to manage the symptoms, am I wrong to not want to put her thru all of the testing? My only concern is that every once in a blue moon, she's lucid for a brief hour or so. Is this common at all with typical vascular dementia or should I be concerned that something else is medically causing the dementia? I don't want to put her through the confusion and expense of needless testing but also don't want to find out later that something else was causing it and we might have caught it in time to do something about it. Any advice on what to do?
