We report a patient with epilepsy who experienced interictal and postictal psychoses. Her psychiatric symptoms consisted of grandiose and fantastic delusions during both psychotic states. During remission, electroencephalography showed bitemporal epileptiform discharges that were predominant in the right temporal region. Epileptiform discharges present during the psychotic states were predominant in the left temporal region. Single-photon emission computed tomography showed hyperperfusion in the left basal ganglia during the interictal psychotic state and hyperperfusion in the right temporal lobe and left basal ganglia during the postictal psychotic state. We suggest that the occurrence of postictal and interictal psychotic states in this patient were associated with a common change in electrographic activity and blood flow.

Background: Many variables may affect approaches of psychiatrists to methamphetamine-associated psychotic disorder (MAP) treatment. This study was aimed to reach adult psychiatrists actively practicing in Turkey through an internet-based survey and to determine their practices and attitudes to MAP treatment.
Methods: In this internet-based study, participants were divided into three groups based on their answers: Those who do not follow-up any MAP patient were group 1 (n = 78), partially involved in the treatment process of at least one patient diagnosed with MAP were group 2 (n = 128), completely involved in the treatment process of at least one patient diagnosed with MAP were group 3 (n = 202).

Background: There is longstanding evidence that the presence of psychosis in neurocognitive disorders is associated with faster deterioration of cognitive function. These reports also describe greater care partner burden, higher rates of institutionalization and functional decline, especially among ethnoculturally diverse persons. The goal of this study is to examine the association of race/ethnicity with rates of psychosis in neurocognitive disorders among ethnoculturally diverse older persons.

Narcolepsy with cataplexy (NT1) is a sleep disorder very rarely associated with early-onset psychosis. The incidence of this association is unknown but appears to be more common in children and adolescents. This combination of diagnoses presents a diagnostic and therapeutic challenge.

Background: Low-grade systemic inflammation has been reported in many psychiatric diseases and is described as a non-severe state of the inflammatory response. Post-traumatic stress disorder (PTSD) is a chronic psychiatric disorder characterized by symptoms of avoidance, re-experiencing and hyperarousal that develop secondary to a serious traumatic event. The trauma itself creates psychological and biological changes in the individual, apart from PTSD.

The atypical static brain functions related to the executive control network (ECN), default mode network (DMN), and salience network (SN) in people with autism spectrum disorder (ASD) has been widely reported. However, their transient functions in ASD are not clear. We aim to identify transient network states (TNSs) using coactivation pattern (CAP) analysis to characterize the age-related atypical transient functions in ASD.
