Epidemiology Study - Overview

Multiple Sclerosis Study Objective

To determine the prevalence and incidence of multiple sclerosis among individuals in a defined population. This objective outlines the primary aim of the study, which is to establish the frequency of multiple sclerosis within a specific age group and geographic area, while also seeking to understand potential factors contributing to its development. Adjustments can be made based on the study's scope, available data, and specific research questions of interest.

Multiple Sclerosis Study USP:

• By integrating advanced imaging techniques with robust statistical analyses, the study aims to provide actionable insights to identify treatment opportunities, target population, and an overview on public health initiatives aimed at mitigating the impact of multiple sclerosis related problems.

• Through meticulous data collection and rigorous methodology, the study not only contributes to the scientific understanding of multiple sclerosis but also serves as a foundation for future research events and healthcare policymaking in addressing this increasingly prevalent health condition.

Multiple Sclerosis related Study Overview:

The study defines multiple sclerosis as an advanced form of health disease. The significance of studying multiple sclerosis epidemiology is due to its increasing prevalence in different age populations.

Multiple Sclerosis Study Design:

Population: The target population (e.g., individuals of age 20 to 40 and above) and the sampling method (e.g., random sampling from healthcare registries or population databases)

Data Collection: Detail methods for identifying acne cases (e.g., clinical examination, imaging studies) and demographic data (age, sex, ethnicity).

Multiple Sclerosis Epidemiological Parameters

• Prevalence: Prevalence rates considered per 1,000 or 10,000 population.

• Incidence: Determine annual incidence rates per 1,000 person-years.

• Risk Factors: Analyze associations between Multiple Sclerosis and potential risk factors (e.g., age, smoking, genetics).

• Geographical Variations: Compare prevalence or incidence rates across different regions or countries.

Multiple Sclerosis Study Summary:

Multiple Sclerosis study summarizes the prevalence, incidence, possible risk factors, and geographic variations of the Multiple Sclerosis worldwide.

Multiple Sclerosis Disease Overview:

Multiple sclerosis is a autoimmune chronic disease that affects the central nervous system. The main characteristics of disease includes inflammation, demyelination, gliosis and neuronal loss. In addition, broad range of neurological symtoms of this disease includes impairment of vision, tingling and numbness, dysfunction of bladder and bowel, focal weakness, also cognitive impairment.

MS has various courses which are segmented as Relapsing-remitting (RR), Primary progressive (PP), Secondary progressive (SP), Progressive-relapsing (PR). Furthermore, sometimes 3 more categories considered within the spectrum of multiple sclerosis includes clinically isolated syndrome, fulminant, and benign.

As per Atlas of MS, third edition data 2.8 million individuals are estimated to have MS worldwide that is 35.9 per 100,000 of people. Rate of incidence in 75 countries studied is 2.1 per 100,000 people per year, mean age of diagnosis identified is 35 years. Females have double chances of developing MS than males. Geographical distribution influence the occurance of MS, in Europe Multiple sclerosis show latitudnal gradient, and people living in area away from equator show greater risk of disease development. Moreover, countries closer to Mediterranean tend to have prevalence rates low.

Multiple Sclerosis can be treated by various medications including disease-modifying therapies which includes injectable or oral medications or infusion therapies which work either by suppressing or modulating the immune system. There are several key players such as Biogen Idec, Novartis, EMD Serono, Sanofi, Teva Pharmaceutical, Bayer, Pfizer, Synthetic Biologic, Active Biotech, and Opexa among others developing treatment solutions for MS.

This review discusses key aspects of the prevalence and incidence of Multiple Sclerosis, It also examines factors known to modify risk, including demographic and environmental influences. Understanding the global epidemiology of multiple sclerosis is essential for effective prevention and management strategies for affected patients.

Multiple Sclerosis Demographic and Environmental Risk Factors:

Age and sex: Women have double chances of diagnosing with MS then men, especially for age group 25 to 40 years. Prevalence of MS globally in women was 32.3 every 100,000 people compared with 15.6 in men. Peak incidence of this disease is around the age of 30 to 34 years. And new diagnosis occurs as early as at around 10 to late 60 years of age. MS shows increasing pattern in age of 10 to 34 years of age and after that gradually goes down, plateauing after age of 60.

Ethnicity: Rate of MS increasing in between African Americans as compared to Whites. Hispanics and Asians are less likely to suffer with MS than whites of European ancestry. 47% increase in risk of MS was seen in Americans while Hispanics Americans were seen with 50% less risk and Asian Americans has 80 % less risk of MS when compared with White Americans (2.9 per Hispanics vs. 6.9 for whites per 100,000 people).

Causes of Multiple Sclerosis:

According to the National Multiple Sclerosis Society ethnicity and geographic location play a role, scientists are not knowing the exact cause and the research on this is still going on, there are certain studies undertaken by scientist to understand the cause, scientist say trigger in environment can cause MS in some people who already have combination of genes supporting the disease.

To understand the exact cause of disease scientist are doing research in areas of immunology, epidemiology, genetics, infectious agents. Increased evidence is suggesting that Vitamin D and sunlight exposure plays role in MS development. Vitamin D is required nutrient for good health , sun exposure provides good source of vitamin D, scientist have identified risk of MS in people with less vitamin D levels in blood, therefore researchers are saying sun exposure can also have link with MS, they suggest that those who live closer to equator are exposed to higher amounts of sunrays so they have natural source of vitamin D in high amount which supports immune function and help to prevent immune mediated diseases like MS.

Another major risk factor which can cause MS is Epstein-Barr virus EBV, study have shown that individuals developing infectious mononucleosis after primary acute infection of EBV have shown 2-3 fold increase in risk of developing MS. One of the longitudinal study involved more than 10 million US military personnel over 20 years period, about 801 individuals have developed MS and 35 of 801 were having EBV seronegative history before the study, except one all other seroconverted before start of MS, this signifies that EBV is major risk factor causing MS, and individuals who were EBV negative , have shown reduced risk of MS development.

Multiple Sclerosis Drugs Market Scope

Driver: The rising prevalence of multiple sclerosis is a primary driver of the multiple sclerosis market's growths. Relapsing-remitting multiple sclerosis (RRMS), primary-progressive MS (PPMS), secondary-progressive MS (SPMS), and progressive-relapsing MS (PRMS) is the types of multiple sclerosis, and their high prevalence rate will influence the market dynamics during the forecast period.

Significant R&D Investment to boost the market growth, Clinical research and R&D investments are attracting huge interest in the multiple sclerosis treatment market. MS is a disease that many pharmaceutical companies are attempting to treat. For instance, Pipeline Therapeutics is testing its PIPE-307, a selective antagonist of the M1 receptor, in clinical trials for multiple sclerosis. In addition to the increased research activities, many research collaborations have also been formed between pharmaceutical companies and research institutes, which has further favoured the market of multiple sclerosis treatment. Pharmaceutical companies of all sizes have been strengthening their pipeline portfolio through increased research on novel candidates. Market growth of multiple sclerosis treatment is likely to be sparked by the launch of these pipeline candidates.

Restraints: MS treatment include disease modifying therapies is expensive, high treatment cost, can hamper the growth of MS drugs market specially in low- or middle-income countries, reimbursement issues add on to restrain the growth of market. Side effects of treatment options available can also be one reason, strict regulatory conditions can pose problems in drug approval process, delay in this process can also be one major reason.
