aging to ad

aging

• congiitvely healthy older adults

• experience some declines cog. functioning

  • working memory

  • reasoning

  • episodic memory

  • processing speed

subjective cognitive dementia

• perceived deficits in cognition

• no objective deficits in cognition

mild cognitve impairment

• declines more severe than what is considered normal for their age

• impairs daily functionning → dementia

moca

• detect mci

• score out of 30

  • over 26 = mci/dementia

clinical dementia rating

• semi structured interview

• score between 0 and 3 for each domain (6)

mci subtypes

• cognitve testing is first

• mci impairs different areas

amnestic mci

• alzheimers

multiple domain mci

• amnestic → alzheimers or vascular

• non-amnestic → lewy body or vascular

limitation of cognitive etsts

• structural damage 10-20y before clinical symptoms

• impossible to determine type of dementia with just cognitive testing

procedures to aid in diagnosis for alzheimers

• brain scans

• lab testys

• neurolofical scan

• genetic tests

pre-clinical alzheimers disease

• healthy adults can have self perceived cognitive deficits

• using questionnaie asking about memory functionig

criteria for alzheimers disease

• without neurodegeneration

• need a t and n
