Markwalder et al developed a grading system for evaluating a patient presenting with a chronic subdural hematoma.
Mental Status |
Neurologic Findings |
Grade |
normal |
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.
