Unraveling the Complexities within Multiple Sclerosis (MS)
Multiple Sclerosis (MS) is a chronic condition that affects the central nervous system (CNS). This disease, which can begin with mild to severe symptoms, is characterised by the immune system attacking the myelin, the protective layer around nerve fibers.
The symptoms of MS are diverse and can vary depending on the location of the lesions in the central nervous system. Some common symptoms include sensory disturbances such as numbness and tingling, muscle weakness and spasticity (especially in legs), balance and coordination problems, visual impairments like blurred vision and optic neuritis, speech difficulties, fatigue, cognitive deficits including memory and information processing problems, emotional changes such as anxiety and depression, bladder and bowel dysfunction, and sometimes sexual dysfunction.
Vision problems are often some of the first symptoms for many people with MS. These may include optic neuritis, diplopia, nystagmus, loss of vision, and blindness. Other common symptoms can include acute or chronic pain, tremors, cognitive issues, difficulty chewing and swallowing, sleep issues, and problems with bladder control.
Difficulty walking can occur due to numbness, difficulty balancing, muscle weakness, muscle spasticity, and vision problems. Speech issues, also known as dysarthria, can range from mild to severe and include slurred speech, "scanning" speech, changes in the volume of speech.
MS can be classified into four types: Clinically isolated syndrome (CIS), Relapsing-remitting MS (RRMS), Primary progressive MS (PPMS), and Secondary progressive MS (SPMS). RRMS involves clear relapses of disease activity followed by remissions, while PPMS involves neurological function becoming progressively worse from the onset of symptoms. SPMS occurs when RRMS transitions into the progressive form.
Certain risk factors for MS include having a close relative with MS, smoking, obesity, and certain autoimmune disorders such as Type 1 diabetes and rheumatoid arthritis. However, it's important to note that MS is not hereditary.
Fortunately, various treatments are available for MS. These include disease-modifying therapies (DMTs) and medications to treat specific symptoms. For example, Ocrelizumab (Ocrevus) is an infusion drug for both RRMS and PPMS, while Kesimpta is an injectable monoclonal antibody treatment for RRMS. Glatiramer acetate (Copaxone) is a self-injectable disease-modifying medication for RRMS.
A healthcare professional performs a neurological exam to diagnose MS, and diagnostic testing may include an MRI scan, Optical coherence tomography (OCT), spinal tap (lumbar puncture), blood tests, Visual evoked potentials (VEP) test, and Brain stem auditory-evoked and sensory-evoked potential tests.
Recently, Ozanimod (Zeposia) has been approved for treating CIS, RRMS, and SPMS. It's crucial to consult with a healthcare professional for a personalised treatment plan.
In conclusion, while MS can present a range of challenging symptoms, understanding the disease and available treatments can help those affected navigate their journey with confidence.
