The #memoir I wrote w/#neurologist Dr. Bruce Miller is about my father's early-onset #Alzheimer's & the devastating grief that accompanies that death by #dementia. Bruce explains how a #brain works & doesn't. Images of #PET scans & #MRI's, & a glossary w/definitions of medical terms -- aphasia & anosognosia -- are included. If you want to learn about the brain circuitry involved in word finding, spatial orientation, behavior, et al. please consider reading it.
