Mild Cognitive Impairment and Dementia Quiz

• Dementia is a chronic, acquired loss of cognitive abilities caused by brain disease or injury.
• Mild cognitive impairment is a condition in which a person's performance on objective neuropsychological testing of cognition is lower than normal, but with maintained daily functions.
• MCI can be categorized into "amnestic" MCI, in which reduced performance on memory is the key finding, versus "non-amnestic" MCI, in which reduced cognitive performance is in a non-memory domain such as language.
• MCI can also be characterized into "single domain" versus "multi-domain" MCI, in which multiple cognitive performance measures are impaired.
• Fluctuations in cognition are present in some conditions, such as neurodegenerative diseases, cerebrovascular disease, and psychiatric conditions, and with medications affecting cognition.
• Cognitive test results can be variable, and a person's cognitive status may become normal or fluctuate between MCI, normal cognition, and dementia.
