Summary

Epilepsia partialis continua, a focal neurological disorder, was observed in an HIV-positive man with syphilis. A simple pen and paper test aided in diagnosing this rare condition by analyzing hand movements.

Area of Science:

Neurology
Infectious Diseases
Movement Disorders

Background:

Epilepsia partialis continua (EPC) presents as continuous focal motor seizures.
Distinguishing EPC from other repetitive movement disorders can be challenging.

Purpose of the Study:

To report a case of EPC in a young HIV-positive male with syphilis.
To highlight the utility of a simple mechanographic test in diagnosing EPC.

Main Methods:

Case report of a patient with right-hand EPC.
Utilized a pen and paper test to record movement frequency, amplitude, and rhythmicity.
Correlated clinical findings with neuroimaging of a left frontal lesion.

Main Results:

The patient exhibited right-hand EPC associated with a left cortico-subcortical frontal lesion.
Mechanographic data provided objective parameters of the involuntary movements.
The findings helped differentiate EPC from other potential causes of repetitive hand movements.

Conclusions:

EPC can occur in the context of HIV and syphilis.
Simple bedside tests can offer valuable diagnostic information for focal motor seizures.
Early and accurate diagnosis of EPC is crucial for appropriate management.
