Patients with aggressive multiple sclerosis (MS) are at increased risk of rapid accrual of disability and disease progression, so early detection is critical
The window of opportunity for treating patients with aggressive MS is narrow, thus, conventional treatment paradigms need to be reconsidered
Aggressive disease warrants aggressive treatment
Therapeutic agents vary extensively throughout the world in terms of their availability, licensing, usage experience and logistics of implementation
Diligent monitoring is crucial for the timely discovery of suboptimal response to therapy
Multiple sclerosis (MS) is a CNS disorder characterized by inflammation, demyelination and neurodegeneration, and is the most common cause of acquired nontraumatic neurological disability in young adults. The course of the disease varies between individuals: some patients accumulate minimal disability over their lives, whereas others experience a rapidly disabling disease course. This latter subset of patients, whose MS is marked by the rampant progression of disability over a short time period, is often referred to as having 'aggressive' MS. Treatment of patients with aggressive MS is challenging, and optimal strategies have yet to be defined. It is important to identify patients who are at risk of aggressive MS as early as possible and implement an effective treatment strategy. Early intervention might protect patients from irreversible damage and disability, and prevent the development of a secondary progressive course, which thus far lacks effective therapy.
