Very few studies in humans have quantified the effect obtained after direct electrical stimulation of the amygdala, in terms of both emotional and physiological responses. We tested patients with drug-resistant partial epilepsies who were explored with intracerebral electrodes in the setting of presurgical evaluation. We assessed the effects of direct(More)
The present proof-of-concept study investigated the feasibility of skin conductance biofeedback training in reducing seizures in adults with drug-resistant temporal lobe epilepsy (TLE), whose seizures are triggered by stress. Skin conductance biofeedback aims to increase levels of peripheral sympathetic arousal in order to reduce cortical excitability. This(More)
BACKGROUND Avoidance and hypervigilance to reminders of a traumatic event are among the main characteristics of post-traumatic stress disorder (PTSD). Attentional bias toward aversive cues in PTSD has been hypothesized as being part of the dysfunction causing etiology and maintenance of PTSD. The aim of the present study was to investigate the cognitive(More)
Emotional distress is one of the most frequently reported seizure precipitants in epilepsy, but little is known about its causes and processes. Interestingly, it is now accepted that emotional distress, such as anxiety, may be accompanied by evolutionary adaptation, or abnormal attentional vigilance toward threatening stimuli. The goal of this research was(More)
Biofeedback is a complementary non-pharmacological and non-surgical therapeutic developed over the last thirty years in the management of drug-resistant epilepsy. Biofeedback allows learning cognitive and behavioral strategies via a psychophysiological feedback loop. Firstly, this paper describes the different types of biofeedback protocols used for the(More)
BACKGROUND Recent investigations have suggested that the occurrence of epileptic seizures is not completely random. In particular, various types of psychological changes or life events may act as triggering factors. OBJECTIVE To identify a possible link between self-perception of the impact of affective precipitants, cognitive responses modulated by(More)
Empirical evidence currently supports the idea that neurovascular dysfunction is involved in the neurodegenerative process of Alzheimer's disease (AD). In fact, epidemiological studies report that i) vascular risk factors are directly associated with an increased incidence of AD and ii) vascular lesions are frequently co-existent with AD. The neurovascular(More)
Transcranial Magnetic Stimulation (TMS) was proposed as a neurophysiological tool almost three decades ago. It now encompasses a very wide range of applications including clinical research and the treatment of psychiatric, neurologic and medical conditions such as depression, schizophrenia, addictions, post-traumatic stress disorders, pain, migraine,(More)
The early assessment of new symptomatic drugs against Alzheimer's disease remains difficult because of the lack of a predictive end-point. The use of a battery including different parameters could improve this early development. In order to test the reverse effect of symptomatic drugs in healthy volunteers, scientists have developed new experimental(More)
To this day, the pharmacological treatment of Alzheimer's disease remains limited to the temporary stabilisation of cognitive decline and the reduction of neuropsychiatric symptoms. It is moreover with great difficulty to predict and select promising drug candidates in the early stages of the discovery and developmental process. In this context, scientists(More)
