Abstract
CASSIANI-MIRANDA, Carlos Arturo and CHEN, Xueyi. Neurocognitive disorder due to neurosyphilis: a case report. rev.colomb.psiquiatr. [online]. 2020, vol.49, n.3, pp.202-207. Epub Jan 17, 2021. ISSN 0034-7450. https://doi.org/10.1016/j.rcp.2018.10.004.
Introduction:
Neurosyphilis is a chronic infectious disease caused by Treponema pallidum that can cause a great variety of neuropsychiatric signs and symptoms, which complicates its diagnosis.
Case description:
This case occurred in a 40-year-old man who consulted the Emergency Department because of a convulsion (de novo) which was related to a chronic condition of cognitive impairment and psychosis. The appropriate studies were performed for the diagnosis of neurosyphilis and the recommended treatment was initiated. The patient presented clinical improvement and was discharged.
Discussion:
Positive VDRL serology results and imaging findings of marked cortical atrophy conducted to consider a late-stage parenchymatous neurosyphilis with serious cognitive impairment and associated psychosis. Treatment with crystalline penicillin was formulated, which reduced the intensity of the patient's symptoms; however, the patient's lack of interest to attend the check-ups significantly reduces his chances of an adequate recovery.
Conclusions:
Neurosyphilis must be suspected in patients with clinically evident neurological or psychiatric symptoms. Analysis of VDRL serology and neuroimaging studies are important as an initial evaluation of the patient and must be complemented with cognitive tests or mental examination to determine the state of cognitive impairment.
