My mom has been diagnosed with dementia, probably vascular, and has had cognitive decline for many years. She spends her days watching TV and eating. She perks up when my brother visits from out of state and when there is a special event, but refuses to engage much in activities at AL. Sometimes she will verbalize that she feels foggy or air headed but does not know why. This may last for days, then she is back to her usual state. Has anyone had this experience and/or had a medical explanation as to cause? I am wondering if she is having a mini stroke during these periods? The feeling really upsets her. We are in the process of establishing new doctors since moving parents close to us, so we do not have a neurologist or psychiatrist at the moment.
