A few years ago I suggested my mom see a doctor about the dementia type symptoms she was having. We went to one appointment then we were supposed to have a MRI. She didn't want the MRI and she decided she didn't want to pursue treatment at all saying that nothing can be done anyway and she would prefer not to take prescription medications. Now the dementia symptoms are much more evident and constant. Does starting medication and other treatment in the mid stages of disease help? Is there any benefit from having a doctor officially diagnose what we already know?
