Question: Physical activity improves mobility, reduces fatigue, enhances mood, and boosts cognitive function, making it a valuable nonpharmacologic complement to disease-modifying treatments (DMT) for multiple sclerosis (MS). Quitting smoking is essential, as it worsens prognosis. Patients should engage in intellectually stimulating activities and follow local vaccine recommendations, including an annual influenza shot. Clinicians must screen for latent infections before starting immunosuppressive or immunomodulatory (ISIM) therapies. Vaccinations should occur 4 to 6 weeks prior to ISIM therapy, and live-attenuated vaccines are contraindicated during treatment, with specific washout periods required. Vaccination should also be postponed during active relapses. Summarize and shorten into succinct paragraph. Need Assignment Help?
