ABSTRACTWe describe the eighth case study of a female diagnosed with anti-N-methyl-d-aspartate receptor encephalitis without an identified tumor who presented with floridly psychotic symptoms following a 2-week prodromal phase with new-onset headaches and presyncopal episodes. While hospitalized, the patient had seizures, autonomic dysfunction, involuntary movements, and a decline in mental status. A subsequent assay was positive for anti-N-methyl-d-aspartate receptor antibodies. In contrast to most reported cases, an initial trial with corticosteroids was therapeutically unsuccessful. Subsequent treatment with intravenous immunoglobulins, however, resulted in a prompt, robust clinical response and enabled the patient to be rapidly discharged from the hospital, with minimal neuropsychiatrie sequelae.

We present a case study of a 67-year-old man who presented with a new onset of recurrent tonic-clonic seizures. He had tested positive to gamma-aminobutyric acid B receptor antibodies in his blood and cerebrospinal fluid, and subsequent CT imaging and transrectal biopsy confirmed the presence of a locally advanced mixed small cell and Gleason 9 adenocarcinoma of the prostate. His seizures remained resistant to treatment with multiple antiepileptic drugs, including sodium valproate, clobazam, topiramate, carbamazepine, phenytoin and lacosamide. He progressed to status epilepticus, which required intravenous immunoglobulin and steroids, followed by plasma exchange 1 week later. The status epilepticus was refractory and required multiple admissions to the intensive care unit.

AbstractAlthough psychotic symptoms are a recognized manifestation of epilepsy, these are more often associated with seizures of the temporal lobe type. While 10% of children with temporal lobe epilepsy develop a psychotic disorder by adulthood, the literature does not report any cases of psychotic disorders associated with frontal lobe seizures in children. This article presents a unique case of a girl whose frontal lobe seizures were associated with delusional psychotic symptoms. Once her seizure disorder was identified through electroencephalography (EEG) and appropriate anticonvulsant therapy was initiated, her associated psychotic symptoms resolved.

AbstractObjective:To identify some of the main features of bipolar disorder for both first-episode (FE) mania and the preceding prodromal phase, in order to increase earlier recognition.Methods:One thousand and ninety manic patients (FE=81, multiple-episodes [ME]=1009) were assessed for clinical and temperamental characteristics.Results:Compared to ME, FE patients reported more psychotic and less depressive symptoms but were comparable with respect to temperamental measures and comorbid anxiety. The following independent variables were associated with FE mania: a shorter delay before correct diagnosis, greater substance use, being not divorced, greater stressors before current mania, a prior diagnosis of an anxiety disorder, lower levels of depression during index manic episode, and more suicide attempts in the past year.Conclusion:In FE patients, the diagnosis of mania may be overlooked, as they present with more psychotic symptoms than ME patients. The prodromal phase is characterised by high levels of stress, suicide attempts, anxiety disorders and alcohol or substance abuse. Data suggest to consider these prodromes as harmful consequences of temperamental predispositions to bipolar disorder that may concur to precipitate mania onset. Their occurrence should therefore incite clinicians to screen for the presence of such predispositions, in order to identify patients at risk of FE mania.

AbstractAnti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is under-recognized in children and adults. It is characterized by prominent neurologic and psychiatric features at first onset. Autonomic manifestations are rarer in children than in adults. We report a 3-year-old male patient with rare manifestation of severe autonomic dysfunctions of the gastrointestinal system and atypical prodromal symptoms. The serum and CSF of the patient were positive for anti-NMDA receptor antibodies, and his electroencephalogram results showed an “extreme delta brush” pattern. The patient had completely recovered by the sixth-month assessment after receiving first-line immunomodulatory treatment. Thus, anti-NMDAR encephalitis should be considered in the differential diagnosis of children with mental status changes and widespread autonomic dysfunction, particularly if symptoms are accompanied by gastrointestinal dysmotility and anhidrosis.
