This study aims to identify cognitive problems in adults with multiple sclerosis (MS). MS can affect memory, thinking speed, and spatial skills, which may impact daily life and work. We will use simple and proven tests to check for these difficulties and see how they affect quality of life. The study will include about 60 patients followed at the neurology day hospital.

Inclusion Criteria:

• Patients aged 18 years or older
• Diagnosed with multiple sclerosis (MS) for at least 6 months according to the 2017 McDonald criteria (SFSEP)
• Receiving disease-modifying treatment and followed in the neurology day hospital of CH Gonesse

Exclusion Criteria:

- Under 18 years old

The study population consists of adult patients (18 years and older) diagnosed with multiple sclerosis for at least six months according to the 2017 McDonald criteria. These patients are currently receiving disease-modifying treatments and are followed at the neurology day hospital of CH Gonesse.
