Study Notes
Gender and Multiple Sclerosis
- Women are more commonly affected by multiple sclerosis (MS) compared to men, with a ratio of about 2-3 women for every man diagnosed.
Relapsing-Remitting MS Characteristics
- Relapsing-remitting MS (RRMS) is primarily characterized by periods of relapse followed by remissions, during which symptoms improve partially or completely.
Prevalence of Multiple Sclerosis
- Approximately 2.3 million people worldwide are affected by multiple sclerosis, highlighting its global impact.
Progressive MS Type
- Secondary progressive MS (SPMS) is characterized by a steady and irreversible decline in function following an initial relapsing-remitting course.
Genetic Risk Factors
- Identical twins have a significantly increased risk of developing MS, with a probability of about 25% if one twin is affected.
Age of Onset
- The typical onset of multiple sclerosis occurs between the ages of 20 and 40; however, it can occur in younger or older individuals.
Remissions in Relapsing-Remitting MS
- During remissions in relapsing-remitting MS, symptoms can diminish or disappear entirely, allowing patients periods of normal function.
Age Group with Rare Onset
- Onset of MS symptoms is rare in individuals below the age of 15, indicating a more common diagnosis in older adolescents and adults.
