Collective tests. MRI ruled out some things. Them talking to me also. Me crying as they asked questions. I remember the dr at the time saying, we'll obviously there's something going on while I was crying. Because my poor Scott wasn't realizing it in the beginning. He was in denial. Not too much later he realized something was wrong. He was all for trying things we had read about or watched online. Coconut for one. It was supposed to help with slowing things down. He declined faster than anyone I've read about. Or known. I worked in a Nursing home and Assisted Living.Was your husband diagnosed with dementia through an MRI or was it a collective of tests?
