96
Q

What does cognitive screening begin with?

A

Observation and conversation

96
Q

What is Implicit (procedural, nondeclarative) memory?

A

Can’t be accessed by conscious recall & occurs through unconscious systems such as movement and perception.

97
Q

How do you conduct a cognitive screen?

A

Use tact with screening, as this line of questioning can create anxiety, defensiveness, and/or uncomfortableness. Allow for adequate time for responses.
