Methylphenidate is commonly believed to lower seizure threshold. The safe use of methylphenidate has not been clarified in patients with attention-deficit hyperactivity disorder (ADHD) and concomitant active seizure or electroencephalographic (EEG) abnormalities. Patients with ADHD and active seizures (n = 57) and patients with ADHD and EEG abnormalities (n = ...

Epilepsy surgery has been successfully performed in patients with tuberous sclerosis complex (TSC) and seizures arising from a restricted epileptogenic area. The outcome of cortical excision depends on accurate pre-surgical identification of the epileptogenic tuber. [11C] alpha-methyl-L-tryptophan (alpha-MTrp) was originally developed to measure serotonin synthesis in vivo with positron emission ...

The alertness level of 143 patients with dementia was investigated. The patients were examined clinically and electroencephalographically, and the results were compared with 21 healthy volunteers. Regional brain syndromes were determined clinically. For the assessment of the EEG, a method was employed that distinguishes alertness-related slow wave activity from abnormal ...

Identification of the epileptic focus is the most important requirement for a successful surgical outcome in intractable epilepsy. Patients with normal MRI on high-resolution imaging pose a significant challenge in this regard. We tried to identify the epileptic focus using interictal / ictal SPECT and ictal EEG patterns in 14 ...

The role of portal-systemic shunting and portal liver hypoperfusion in the pathophysiology of central nervous system dysfunction of cirrhosis is not yet well defined. It is well known that one of the most important collateral vessels (CV) is a patent paraumbilical vein (PUV) but there is controversy regarding its clinical ...

We studied single-event and average BOLD responses to EEG interictal epileptic discharges (IEDs) in four patients with focal epilepsy, using continuous EEG-fMRI during 80-min sessions. The detection of activated areas was performed by comparing the BOLD signal at each voxel to a model of the expected signal. Since little is ...

Malformations of cortical development (MCD) are a diverse group of diseases that exhibit both genetic and phenotypic heterogeneity. While previous studies have described the clinical, MRI, and/or EEG features of specific malformations, structure and function have not been correlated across a wide spectrum of these disorders. We reviewed the medical ...

The routine EEG study may prove inadequate in selected patients with recurrent and unprovoked seizures. Video-EEG monitoring is an important diagnostic innovation that may be used to confirm the diagnosis of a seizure disorder and classify seizure type. The methodologies and clinical applications of video-EEG monitoring are reviewed. Long-term EEG ...

BACKGROUND: Although so-called "benign" epilepsy with centrotemporal spikes (BECTS) always has an excellent prognosis with regard to seizure remission, behavioral problems and cognitive dysfunctions may sometimes develop in its course. To search for clinical or EEG markers allowing early detection of patients prone to such complications, the authors conducted a ...

Nonconvulsive status epilepticus (NCSE) is often diagnosed based on abolition of rhythmic sharp waves by benzodiazepines. It is possible that sharp waves resulting from metabolic (nonepileptic) encephalopathies may also respond to benzodiazepines and are potentially misdiagnosed as NCSE. The authors hypothesized that triphasic waves (TW) resulting from metabolic encephalopathy are ...
