There must also be a significant decline in function that is severe enough to interfere with work or social life. As the disorder progresses, individuals with dementia often fail to recognize family members, are unable to express themselves clearly and meaningfully, and often undergo dramatic personality changes. In the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), dementia has been relabeled Major Neurocognitive Disorder. Mild cognitive impairment has been relabeled Minor Neurocognitive Disorder. Because this newer terminology has not been widely disseminated through the clinical world, we will continue to use the names dementia and mild cognitive impairment throughout this chapter.
