Epidemiology Study - Overview

Dyslexia Study Objective:

To determine the prevalence and incidence of Dyslexia among individuals in a defined population. This objective outlines the primary aim of the study, which is to establish the frequency of Dyslexia 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.

Dyslexia Study USP:

• This epidemiological study on Dyslexia stands out due to its comprehensive approach in establishing precise prevalence rates, identifying novel risk factors, and exploring geographical variations in a diverse population.

• 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 Dyslexia related health problems.

• Through meticulous data collection and rigorous methodology, the study not only contributes to the scientific understanding of Dyslexia but also serves as a foundation for future research events and healthcare policymaking in addressing this increasing Dyslexia cases.

Dyslexia related Study Overview:

The study Defines Dyslexia as an advanced form of disease. The significance of studying Dyslexia epidemiology is due to its increasing prevalence in different age populations.

Dyslexia Study Design:

Population: The target population and the sampling method (e.g., random sampling from healthcare registries or population databases)

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

Dyslexia 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: Analyse associations between obesity and potential risk factors (e.g., age, smoking, genetics).

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

Dyslexia study summary:

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

Dyslexia Disease overview:

Dyslexia is a neurobiological learning disability, affecting many individuals in world, causing problems to patients in processing language, challenges to read, write and spell accurately, making it one of the major health problems.

Dyslexia based on the cause is segmented into developmental and acquired types.

Developmental dyslexia is present in patients from birth and includes primary and secondary dyslexia. Primary dyslexia is caused due to inherited genes or genetic mutations. It is observed that 40 to 60% children get dyslexia whose parents are suffering from it. In primary type dysfunction is found to be on left side of the brain, involved in reading, which affects persons language processing ability. Issues in neurological development during the foetal period (in the womb) causes Secondary dyslexia, symptoms are seen in early childhood. Acquired dyslexia is caused due to in injury or illness in childhood or adulthood which can be brain trauma or stroke or dementia, also known as trauma dyslexia or alexia.

There are many service-based treatment option for dyslexia treatment, it may involve, time spent with speech and language therapist, tutors, special education teachers, early intervention will give importance to vocabulary, comprehension, necessary skills like phonics. As students start taking education intervention will try to improve word meaning understanding, improved comprehension, more challenging reading and other strategies to excel.

Strategies to help them to overcome their health challenges include use of taping lectures instead of writing notes, listening to books on tape rather than reading them, using flash cards checking spelling and grammar using computer software.

Other supporting Treatment medications used for dyslexia are Antihistamines, Central Nervous Stimulant, Anti-Myoclonic, Attention-Deficit Hyperactivity Disorder (ADHD), Drug. Several key market players for dyslexia include Pfizer, Inc. (US), Speechify Inc. (US), Jubilant Pharma Limited (Singapore), Lingit AS (Norway), Soli (UK), Novartis AG (Switzerland), Lyfta (UK), GlaxoSmithKline (UK), Teva Pharmaceutical Industries Ltd (Israel), Eli Lilly & Company (US), RPG Life Sciences Ltd (India), Hopalai D.O.O. (Slovenia).

Every one out of ten people are found to be affected by dyslexia, out of global population of 7.8 billion people, 780 million people have dyslexia across the world. 5 to 15 % of Americans with 14.5 to 43.5 million children and adults are seen to be dyslexic. Approximately 1 out of 5 students in U.S, that is about 15 to 20% of population is suffering with language-based learning disabilities such as dyslexia.

Dyslexia Demographic and Environmental Risk Factors:

Age and sex: Dyslexia prevalence is found to be seen in higher rate in boys than girls, with nearly 2:1 ratio compared to girls having low prevalence rates. According to a 2024 research study published in NCBI percentage of dyslexia in 3^rd grade boys and girls was 71.4% and 28.6%. Similarly, the percentages were 80.4% and 19.6%, 71.9% and 28.1%, and 75% and 25% in the 4th, 5th, and 6th grades respectively. The prevalence was seen to be highest in males, about 80% and lowest in females about 20%.

Risk Factors causing Dyslexia: Genetics has major role to play in dyslexia cause. Research shows that dyslexia can run in families can run in families due to the hereditary component, close family member suffering with dyslexia like parent or sibling, increases chances of other members of family getting affected with dyslexia as well. Premature birth, low weight, prenatal and perinatal complications can contribute to development of delays and disruptions in brain development, which can increase chances of dyslexia in these individuals. Acquired dyslexia can be caused to individuals due to illness and injury like stroke, brain trauma, dementia.

Dyslexia Market Scope:

Drivers: A large population suffering from learning disabilities prone to developing dyslexia is adding up several patients with dyslexia. Additionally, an increasing number of learning programs focused on dyslexia is helping the growth of the dyslexia treatment & diagnosis market. For example, non-profit organizations such as The African Dyslexia Organization is raising donations for “Free dyslexia diagnosis children fund” and increasing awareness about dyslexia in the region. An increase in the level of awareness in developing regions about dyslexia is expected to increase the diagnosis rate during the forecast period.

Restraints: Lack of awareness about this disability condition, symptoms, treatments. Other challenge is delay in diagnosis the disability are the major factors related to dyslexia which hampers the growth of dyslexia market.
