“…Today the panic disorder agoraphobia (PDA) is nosologically distinct from complex partial epilepsy (CPE), but there are clinical and pathogenetic hints of overlap between manifestations of the two disorders concerning the evaluation of psychosensorial phenomena in PDA or affective phenomena in CPE. Toni et al (135), investigating the psychosensorial symptoms in PDA and CPE outpatients, found broad similarities between the two conditions: This symptomatologic overlapping further supports the hypothesis of a common neurophysiologic substrate linking CPE phenomena with PDA.…”

Summary: This chapter deals with some aspects of psychiatric disturbances in people with epilepsy. Because depression and its treatment are extensively described later in this issue, they are not discussed here. The same pertains to forced normalization. Key Words: Epilepsy-Anxiety-PsychosisDepress ion-Qua1 i ty of 1 i fe-Ps e u do s ei zure s-A n t idepressants-Antipsychotics-Antiepileptic drugs.Although most people with epilepsy lead a normal emotional and cognitive life, neurobehavioral problems can be found in a large number of patients. Higher rates of psychopathology are observed in people with epilepsy relative to the general population (1,2), to other neurologic control groups (3), and to people with chronic nonneurologic disorders (1,4). In particular, increased psychopathology is more common in temporal lobe epilepsy (TLE) than in generalized epilepsy (5). Nevertheless, many issues remain highly controversial, owing in part to several methodologic problems, such as the nosographic approach, the sample examined, the type of control groups, the comparison among nonhomogeneous forms of epilepsy, and the different antiepileptic drugs (AEDs).Psychiatric disturbances can be related either to involvement of brain structures (biologic pathogenesis) or to the chronic characteristics of epilepsy (psychosocial pathogenesis). These psychiatric symptoms may develop in relationship to the seizures (in prodromal, ictal, or postictal periods) but more commonly are present in a chronic interictal condition.The wide range of clinical diversity is related to the anatomic foci, to patterns of spread, and to biologic or psychological differences among patients. Interictal behavioral changes in epilepsy remain controversial and difficult to define, mainly because pathogenesis may be attributable to several factors, such as epilepsy itself, possible brain lesions, the AEDs prescribed, and psychosocial problems (6). On the other hand, the existence of cognitive changes in epilepsy is well established, and Addrress correspondence and reprint requests to Dr. Riccardo Tom at Dipartimento di Neuroscienze, via Cherasco 11, 10126 Torino, Italy.sometimes the presence of cognitive disorders can facilitate the appearance of psychiatric disturbances (7).One of the most widely discussed problems is the incidence of psychiatric pathology in epilepsy, with a wide range of values in the literature related to the type of study. Epilepsy is characterized by a broad spectrum of severity. Ideally, patients for study trials should be selected consecutively from a general epilepsy population, but most epidemiologic studies are carried out in centers for epilepsy and include many refractory subjects who demonstrate a range of pathologic disturbances more severe than those observed in the general population of patients with epilepsy. In community studies, the prevalence of associated psychiatric disorders is low, whereas in specialty referral centers, particularly those serving indigent populations, the prevalence can rise to 25-50%: Among patient...

“…Toni et al found a striking overlap in reported psychosensorial symptoms reported by patients with panic disorder-agoraphobia and those with complex partial epilepsy (43). However, as countless other examples in medicine demonstrate, similar phenomenology does not necessarily imply similar pathophysiology: Tokunaga et al found a very different pattern of benzodiazepine receptor binding potential in anxiety and somatoform disorder subjects compared with epilepsy subjects, suggesting divergent etiologic mechanisms (44).…”

“…However, the core cognitive neuropsychiatric concept heredissociation-and déjà vu experience do not seem to be related in healthy populations [32], and anxiety disorder patients with or without depersonalization and derealization symptoms experienced déjà vu and déjà vécu to equal degrees: between one third and one half of all patients studied [33]. In sum, déjà vu may not be seen as a meaningful symptom in psychiatry, although the response to it by schizophrenia patients may be more pronounced, and certain groups tend to experience it more often than healthy groups (anxiety disorders, people with derealization/depersonalization).…”

Déjà vu is characterized by the recognition of a situation concurrent with the awareness that this recognition is inappropriate. Although forms of déjà vu resolve in favor of the inappropriate recognition and therefore have behavioral consequences, typical déjà vu experiences resolve in favor of the awareness that the sensation of recognition is inappropriate.The resultant lack of behavioral modification associated with typical déjà vu means that clinicians and experimenters rely heavily on self-report when observing the experience. In this review, we focus on recent déjà vu research. We consider issues facing neuropsychological, neuroscientific, and cognitive experimental frameworks attempting to explore and experimentally generate the experience. In doing this, we suggest the need for more experimentation and a more cautious interpretation of research findings, particularly as many techniques being used to explore déjà vu are in the early stages of development.
