Markwalder et al developed a grading system for evaluating a patient presenting with a chronic subdural hematoma.
Mental Status
Neurologic Findings
Grade
normal
0
fully alert and conscious; may have mild symptoms such as headache
none or mild (reflex asymmetry)
1
drowsy or disoriented
variable neurologic deficits such as hemiparesis
2
stuporous but responds appropriately to noxious stimuli
severe focal signs such as hemiplegia
3
comatose, with absent motor responses to painful stimuli
decerebrate or decorticate posturing
4
Prognosis was good in Grades 0 and 1, fair in Grade 2, and guarded in Grades 3 and 4.
