Symptoms of Dementia (NCD)
- Virtually non-existent before 65
- At 80, about 33% of the population has dementia
DSM Criteria for NCD
- Significant cognitive decline from prior level of functioning
- Evidence for decline found either by self-report or during testing
- Cognitive decline interferes with independence or daily living
- Is not better explained by another disorder
Common Clinical Sequelae for NCD
- Mood disturbances common – high lability
- Increased anxiety
- Unpredictable periods of intense agitation, and frustration
- Paranoia and delusional beliefs may emerge, but without disorganizations symptoms
Neurocognitive disorders
- Known pathology
- Biologically informed diagnosis
What is Neurocognition?
- Working memory – anytime you are trying to hold and idea without losing it
- Attention/Cognitive control – Ability to direct mind to focus on what you want
- Cognitive flexibility – approach a problem in a different way, recognizing circumstances
have changed and one way of learning something is no longer viable
- Abstract representation – ability to represent things in non-concrete ways. E.g. algebra is
a system of abstract representations of numerical quantities
Screening tests:
- MoCA
- Mini-Mental State

Document Summary
At 80, about 33% of the population has dementia. Significant cognitive decline from prior level of functioning. Evidence for decline found either by self-report or during testing. Cognitive decline interferes with independence or daily living. Unpredictable periods of intense agitation, and frustration. Paranoia and delusional beliefs may emerge, but without disorganizations symptoms. Working memory anytime you are trying to hold and idea without losing it. Attention/cognitive control ability to direct mind to focus on what you want. Cognitive flexibility approach a problem in a different way, recognizing circumstances have changed and one way of learning something is no longer viable. Abstract representation ability to represent things in non-concrete ways. E. g. algebra is a system of abstract representations of numerical quantities. Seeing a series of random letters and symbols. Have a target and you have to remember if your target occurred x-number backs. If your target letter was an x say what the letter/symbol right before it was.
