We report two patients of neurosyphilis with periodic lateralized epileptiform discharges (PLEDs) in the EEG. Patient 1, a 32-yr-old man manifested with rapidly progressive cognitive decline and abnormal behavior and recurrent generalized tonic-clonic seizures. EEG revealed periodic epileptiform discharges arising from the anterior temporal and frontal region, predominantly from the right. Diffusion weighted MRI of brain did not show any focal restricted diffusion. Patient 2, a 33-yr-old woman presented with 2-year history of behavioral abnormalities, generalized tonic-clonic seizures and unconcerned urinary incontinence. EEG revealed PLEDS arising from the left anterior temporal region. Her CT scan showed gross cerebral atrophy. Both the patients improved partially with treatment and PLEDs resolved completely. PLEDs may be recorded in EEG of patients with neurosyphilis without imageological evidence of focal cerebral lesion.

D009494	Neurosyphilis	Infections of the central nervous system caused by TREPONEMA PALLIDUM which present with a variety of clinical syndromes. The initial phase of infection usually causes a mild or asymptomatic meningeal reaction. The meningovascular form may present acutely as BRAIN INFARCTION. The infection may also remain subclinical for several years. Late syndromes include general paresis; TABES DORSALIS; meningeal syphilis; syphilitic OPTIC ATROPHY; and spinal syphilis. General paresis is characterized by progressive DEMENTIA; DYSARTHRIA; TREMOR; MYOCLONUS; SEIZURES; and Argyll-Robertson pupils.

D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon
D002540	Cerebral Cortex	The thin layer of GRAY MATTER on the surface of the CEREBRAL HEMISPHERES that develops from the TELENCEPHALON and folds into gyri and sulci. It reaches its highest development in humans and is responsible for intellectual faculties and higher mental functions.

D004569	Electroencephalography	Recording of electric currents developed in the brain by means of electrodes applied to the scalp, to the surface of the brain, or placed within the substance of the brain.	EEG,Electroencephalogram,Electroencephalograms
D004827	Epilepsy	A disorder characterized by recurrent episodes of paroxysmal brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology (e.g., post-traumatic), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal patterns (e.g., nocturnal epilepsy).
