Answer to Question 1
The DSM-5 diagnostic criteria for Major or Mild Neurocognitive Disorder Due to Alzheimer's Disease includes: 1. clear evidence of decline in memory or learning; 2. steadily progressive, gradual decline in cognition, without extended plateaus 3 . No evidence of mixed etiology (i.e. absence of other neurocognitive or cerebrovascular disease, or another neurological or systemic disease or condition likely contributing to cognitive decline).
Alzheimer's Disease, like other neurocognitive disorders, is typically diagnosed only after extensive interviews and history taking with the patient and close relatives or friends, cognitive testing and observation, a thorough medical evaluation, and often a neuroimaging test. To diagnose a neurocognitive disorder, cognitive difficulties are compared with prior levels of functioning.
