I - No Response.
Patient does not respond to external stimuli and appears asleep.
II - Generalized Response.
Patient reacts to external stimuli in nonspecific, inconsistent,
and nonpurposeful manner with stereotypic and limited responses.
III - Localized Response.
Patient responds specifically and inconsistently with delays
to stimuli, but may follow simple commands for motor action.
IV - Confused, Agitated Response.
Patient exhibits bizarre, nonpurposeful, incoherent or inappropriate
behaviors, has no short-term recall, attention is short and
V - Confused, Inappropriate, Nonagitated Response.
Patient gives random, fragmented, and nonpurposeful responses
to complex or unstructured stimuli - Simple commands are followed
consistently, memory and selective attention are impaired,
and new information is not retained.
VI - Confused, Appropriate Response.
Patient gives context appropriate, goal-directed responses,
dependent upon external input for direction. There is carry-over
for relearned, but not for new tasks, and recent memory problems
VII - Automatic, Appropriate Response.
Patient behaves appropriately in familiar settings, performs
daily routines automatically, and shows carry-over for new
learning at lower than normal rates. Patient initiates social
interactions, but judgment remains impaired.
VIII - Purposeful, Appropriate Response.
