Surgery has proven quite effective in patients with pharmacoresistant temporal lobe epilepsies (TLE). Unilateral hippocampal sclerosis, in particular, is associated with positive seizure control following surgery. However, surgical relief from epileptic seizure activity may come at the expense of neuropsychological deficits. Thus, during the evaluation of patients being considered for epilepsy ...

Autoimmune-mediated encephalitis may occur as a paraneoplastic or as a nonparaneoplastic condition. The role of neuroimaging in autoimmune-mediated encephalitis has changed in the last decade partly due to improvements in sequence optimisation and higher field strength and partly due to the discovery of an increasing number of antibodies to neuronal cell and cell membrane antigens. Imaging is i...

Limbic encephalitis (LE) is an autoimmune-mediated disorder that affects structures of the limbic system, in particular, the amygdala. The amygdala constitutes a brain area substantial for processing of emotional, especially fear-related signals. The amygdala is also involved in neuroendocrine and autonomic functions, including skin conductance responses (SCRs) to emotionally arousing stimuli. ...

Monkeys with dorsolateral frontal ablations have been found able to learn go-no-go alternation despite a grave deficit in classical alternation. Subsequently, evidence has implicated certain limbic lesions in go-no-go types of task, e.g., passive avoidance and successive discriminations. This study was undertaken to test whether these limbic lesions would affect go-no-go more than classical alt...

PEARLS Limbic encephalitis is an inflammatory condition of the brain, often characterized by the subacute onset of short-term memory loss, disorientation, seizures, behavioral disturbance, and psychiatric symptoms. Besides paraneoplastic syndromes with onconeural antibodies targeted against intracellular neuronal antigens, limbic encephalitis may also arise from nonparaneoplastic mechanisms wit...

BACKGROUND Voltage-gated potassium channels are thought to be the target of antibodies associated with limbic encephalitis. However, antibody testing using cells expressing voltage-gated potassium channels is negative; hence, we aimed to identify the real autoantigen associated with limbic encephalitis. METHODS We analysed sera and CSF of 57 patients with limbic encephalitis and antibodies at...

BACKGROUND AND PURPOSE The limbic system, relevant to memory and emotion, is an interesting subject of study in healthy and diseased individuals. It consists of a network of gray matter structures interconnected by white matter fibers. Although gray matter components of this system have been studied by using MR imaging, the connecting fibers have not been analyzed to the same degree. Cerebrospi...

Autoimmune limbic encephalitis (ALE) associated with systemic lupus erythematosus (SLE) is a rare entity with few reports in the literature to date. In general, ALE associated with SLE has a satisfactory response to immunosuppressive treatment (RIT), but the pathogenesis of this association is poorly understood and may include an autoimmunity component. We report a case study describing the dia...

Alterations in anxiety-related processing are observed across many neuropsychiatric disorders, including bipolar disorder. Though polymorphisms in a number of circadian genes confer risk for this disorder, little is known about how changes in circadian gene function disrupt brain circuits critical for anxiety-related processing. Here we characterize neurophysiological activity simultaneously ac...
