mcdonald_ms_criteria_2010: McDonald Criteria for Multiple Sclerosis (2010 Revision)

Description

Evaluates the 2010 Revised McDonald Criteria for the diagnosis of Multiple Sclerosis (MS). These criteria allow for the diagnosis of MS in patients with a first clinical demyelinating event (Clinically Isolated Syndrome) using MRI evidence to substitute for clinical dissemination in space (DIS) and/or time (DIT).

Usage

clinical_lesions

Numeric. Number of lesions with objective clinical evidence. (1 or >=2).

dis_demonstrated

Numeric (0 or 1). Dissemination in Space (DIS) demonstrated by MRI (>=1 T2 lesion in >=2 of 4 MS-typical regions: periventricular, juxtacortical, infratentorial, or spinal cord). (1 = Yes).
