Background:

Sexual dysfunction is common in multiple sclerosis (MS).
Hypersexuality is a rare manifestation, often linked to cognitive impairment or psychiatric conditions.
Isolated hypersexuality in MS is exceptionally rare.

Observation:

A case of a multiple sclerosis patient experiencing recurrent episodes of significantly increased libido.
Clinical, neuropsychological, electrodiagnostic, and neuroimaging assessments were conducted.
Hormonal studies revealed no significant endocrine abnormalities.

Findings:

Neuroimaging and neuropsychological evaluations indicated frontal lobe dysfunction.
The patient's hypersexual episodes correlated with these neurological findings.
No hormonal imbalances were identified as a cause.

Implications:

Episodic hypersexuality may represent a transient neurological manifestation in MS.
This finding expands the spectrum of sexual dysfunction associated with MS.
Highlights the importance of considering neurological causes for unusual behavioral changes in MS patients.
