Disease category
Multiple sclerosis (MS) is a neurological disease that affects the brain and spinal cord, characterized by damage to the myelin surrounding nerve fibers.
Core mechanism
The exact cause is unknown, but it has been suggested that an autoimmune process, in which the immune system mistakenly attacks its own healthy cells, may be involved.
Main causes · related factors
Myelin damage can slow or block nerve signals between the brain and the body, leading to various neurological symptoms.
Representative manifestations
Representative clinical manifestations include visual disturbances, muscle weakness, coordination and balance problems, numbness or paresthesia, and cognitive/memory issues.
Individual differences
It is more common in women and typically begins between the ages of 20 and 40, but the pattern of onset and severity can vary by individual.
Diagnosis
The course ranges from mild to severe, and some individuals may experience a decline in the ability to write, speak, or walk.
Management
Diagnosis is made by comprehensively integrating medical history, physical and neurological examinations, MRI, and necessary additional tests, rather than relying on any single specific test.
Treatment/Research Status
Since there is no specific single diagnostic test, diagnosis should not be confirmed based solely on MRI or a single symptom; other causes and temporal patterns must be evaluated together.
Read Evidence
Management may include pharmacotherapy to slow disease progression and control symptoms, as well as physical and occupational therapy to help maintain function.
Key Precautions
There is currently no cure for MS, but medications can help slow disease progression and assist in symptom control.

At a Glance

Multiple sclerosis (MS) is a neurological disease that affects the brain and spinal cord, characterized by damage to the myelin surrounding nerve fibers.

Representative clinical manifestations include visual disturbances, muscle weakness, coordination and balance problems, numbness or paresthesia, and cognitive/memory issues.

How the disease works

The exact cause is unknown, but it has been suggested that an autoimmune process, in which the immune system mistakenly attacks its own healthy cells, may be involved.

Myelin damage can slow or block nerve signals between the brain and the body, leading to various neurological symptoms.

Variations in presentation among individuals

It is more common in women and typically begins between the ages of 20 and 40, but the pattern of onset and severity can vary by individual.

The broad framework of diagnosis and management

The course ranges from mild to severe, and some individuals may experience a decline in the ability to write, speak, or walk.

Diagnosis is made by comprehensively integrating medical history, physical and neurological examinations, MRI, and necessary additional tests, rather than relying on any single specific test.

Current status of treatment

Since there is no specific single diagnostic test, diagnosis should not be confirmed based solely on MRI or a single symptom; other causes and temporal patterns must be evaluated together.

Management may include pharmacotherapy to slow disease progression and control symptoms, as well as physical and occupational therapy to help maintain function.

There is currently no cure for MS, but medications can help slow disease progression and assist in symptom control.

How to read clinical trials

Clinical trial registration information is useful for verifying the design and status of a study, but the registration of NCT06195800 alone cannot be used to determine efficacy, safety, approval, or whether it constitutes standard treatment.

Points to verify during clinical consultations

In clinical practice, it is important to confirm the onset and changes in symptoms, visual, sensory, motor, and cognitive functions, impact on daily life, current treatments and side effects, and plans for additional testing and follow-up.
