Abstract:
Progressive multifocal leukoencephalopathy (PML) is not limited to HIV. In polymedicated or immunomodulated patients, PML can present with subacute cognitive, language, or motor deficits. For general practitioners, the key is to consider PML, review at-risk medications, arrange urgent brain MRI and lumbar puncture, and refer to neurology. This article provides a practical approach focused on recognition, initial workup, and coordination with hospital teams, illustrated by a case.
Insights
Progressive multifocal leukoencephalopathy (PML) can affect non-HIV patients, presenting with neurological deficits. General practitioners should suspect PML, check medications, and initiate urgent workup and neurology referral.
Area of Science:
- Neurology
- Infectious Diseases
Background:
- Progressive multifocal leukoencephalopathy (PML) is a rare, opportunistic demyelinating disease.
- While historically associated with HIV/AIDS, PML occurs in other immunocompromised states.
Purpose of the Study:
- To outline a practical approach for general practitioners to recognize and manage PML.
- To emphasize early diagnosis and referral in non-HIV patients.
Main Methods:
- Review of clinical presentation and diagnostic workup for PML.
- Case illustration of PML in a polymedicated patient.
Main Results:
- PML can manifest with subacute cognitive, language, or motor impairments.
- Early recognition and intervention are crucial for patient outcomes.
Conclusions:
- General practitioners play a vital role in identifying PML in at-risk populations.
- Prompt neuroimaging, cerebrospinal fluid analysis, and specialist consultation are essential.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
