• The early bird catches the worm
Intellectual Function
• Judgment
– You arrive home without a house key, what
alternatives do you have?
• Short term memory test?
– 3 words
– Repeat in 5 minutes
– Amnesia
• Loss of memory
Thought Content
• Are the thoughts…?

Spontaneous
Natural
Clear
Relevant
Coherent
Thought Content
• Fixed ideas
• Preoccupations
Hallucinations
• False perceptions
(sensory)
• Does not have an
external stimuli
• Patients see, hear,
taste things that are
not really there
Illusions
• Has a real external
stimuli, but the patient
misinterprets the
stimuli
Delusions
• False beliefs
Emotional Status

Facial expressions,
body language
Perception
• Agnosia
– The inability to
interpret or recognize
objects

– Parietal lobe
Motor Ability
• Ask to perform a small
task
• Understanding +
motor strength
• Movement smooth,
coordinated
