What is the prevalence of Transverse myelitis?

How many people does Transverse myelitis affect? Does it have the same prevalence in men and women? And in the different countries?


Transverse myelitis is a rare neurological disorder characterized by inflammation of the spinal cord. It affects people of all ages, but it is more commonly diagnosed in adults between the ages of 10 and 19 or 30 and 39. The exact prevalence of transverse myelitis is difficult to determine due to its rarity and the lack of comprehensive population-based studies. However, it is estimated that the annual incidence of transverse myelitis ranges from 1 to 8 cases per million people.


Transverse myelitis can occur as an isolated incident or as a symptom of an underlying condition such as multiple sclerosis, neuromyelitis optica, or viral infections. It can cause a wide range of symptoms including weakness, sensory disturbances, pain, and bladder or bowel dysfunction. The severity and duration of symptoms can vary greatly from person to person.


While transverse myelitis is considered a rare disorder, it is important to raise awareness about its existence and potential impact on individuals. Early diagnosis and prompt treatment are crucial for managing symptoms and preventing further damage to the spinal cord.

TM has a conservatively estimated incidence of between 1 and 8 new cases per million per year, or approximately 1400 new cases each year. Although this disease affects people of all ages, with a range of six months to 88 years, there are bimodal peaks between the ages of 10 to 19 years and 30 to 39 years.

The epidemiology of TM depends on its underlying cause. The annual incidence of idiopathic complete TM is uncertain, but conservative estimates based on studies in US, European, and Israeli populations range from 1 to 4 cases per million, with a bimodal distribution of age presentation, peaking at ages 10 to 19 and 30 to 39 years. A population-based study estimated a mean annual incidence rate of 0.82 per 100,000 person-years, or 1.2 per 100,000 person-years for adults. Acute partial TM commonly heralds or accompanies multiple sclerosis (MS), which affects up to 0.3% of persons of Northern European ancestry. The pattern of longitudinally extensive TM is commonly associated with neuromyelitis optica spectrum disorders, which may account for approximately 1% of all CNS demyelinating disease in North American and European populations, a somewhat greater proportion of African-Americans and Hispanics, up to 30% in the Japanese population, and virtually all cases in ethnic or racial groups in which typical MS is virtually absent, such as aboriginal peoples of North America and black Africans. Onset may occur at any age. MS-associated cases typically occur between ages 20 and 50 years (median about 29 years) whereas the median onset age for neuromyelitis optica-related cases is about a decade later. There is a female predominance in all subtypes. These syndromes also affect children, although the incidence is unknown. The treatment of TM in children is usually the same as in adults.

1 to 8 cases per million per year

4.6 people in 1 million

It affects men, women and children of all ages. There is no age limit. Even infants can get TM.

8/24/17 by Elizabeth 1200

My understanding is it is rare affecting only like 1400 people per year in the US. I believe it hits more young people than say those over 40. I believe it affects women more but I could be wrong.

Can affect anyone, any age, 4.6 in 1,000.000 people are affected, thats less than one in twoo hundred thousand.

Prevalence of Transverse Myelitis worldwide is around 1 in 5million ranging in age from infants to 80 years old. The peak age seems to be 10-19 and 30-39 makes and females in equal proportions.

in the USA, about 1400 people are diagnosed with TM each year

I dont know the exact numbers but I did read there are less than 2000 cases reported per yer.

Transverse Myelitis is a rare neuroimmune condition.

I have an idea that 1 in a million.

Affects more older than 30 years without distinguishing sex; very few cases in children up to 10 years and less under that age. I have a daughter that is 5 years old, he was diagnosed with a transverse trasversa at the cervical level high, affecting the C2 to D2. This is why it is very difficult to find out more about it.

It is said that approximately 1/1000000

More children than adults.

The acute transverse myelitis is inflammation that affects the spinal cord in its entire width (transversely), thereby blocking the transmission of nerve impulses that enter or leave the spinal cord. It affects more women between the ages of 30 to 55 years old
