Background: Reflex epilepsy is characterized by seizures that are triggered in response to a specific stimulus and tooth-brushing epilepsy is an extremely rare form of reflex epilepsy in which the seizures are mainly induced by the act of tooth brushing. In this report, we describe an epilepsy patient whose seizures were exclusively triggered by the use of a powered toothbrush.
Methods And Results: A 31-year old female had been treated for partial epilepsy of left temporal or frontal lobe for 20 years and she did not have seizures for the last 3 years. However, she experienced periods of auras, partial complex seizures, and nocturnal generalized seizures after she started using a powered toothbrush. The interictal electroencephalography revealed slow wave paroxysm over the left temporal or frontal lobe.
Conclusions: This case report is, to our knowledge, the first report of reflex epilepsy in which the seizures were triggered by the use of a powered toothbrush. Possible mechanisms to explain the novel type of this rare disorder are discussed.

Cerebral venous sinus thrombosis (CVST) is the causative factor in a small proportion of strokes. It primarily affects individuals aged less than 55 years, with up to two-thirds of cases affecting females. It can be precipitated by a myriad of transient or permanent risk factors that result in a prothrombotic state.

Introduction: The onset of symptoms in Rapid-onset dystonia-parkinsonism (RDP) is typically over days to weeks and is often triggered by stressors like fever or childbirth. Limited information is available on how the motor and nonmotor symptoms evolve over the course of the disease. Our longitudinal study analyzed data from a cohort of RDP patients, documenting their symptoms across multiple visits.

Early detection of focal cortical dysplasia (FCD) using brain MRI in young children presenting with drug-resistant epilepsy may facilitate prompt surgical treatment, resulting in better control of seizures and decreased associated cognitive difficulties. Characteristics of FCD described in the literature are predominantly based on MRI findings in a fully myelinated brain; therefore, changes occurring during early brain maturation are not well known. In this case report, we describe distinct MRI features of a FCD visualized best before completion of myelination of the cortex and subcortical white matter.

Neurosyphilis-induced dementia represents a severe manifestation of tertiary syphilis, characterized by cognitive and neuropsychiatric impairments. This condition arises from the progression of syphilis to the central nervous system, where the spirochete causes damage through invasion, chronic inflammation, and neurodegeneration. The pathophysiology involves chronic inflammatory responses, direct bacterial damage, and proteinopathies.
