Prior genome-wide association studies (GWAS) of major depressive disorder (MDD) have met with limited success. We sought to increase statistical power to detect disease loci by conducting a GWAS mega-analysis for MDD. In the MDD discovery phase, we analyzed more than 1.2 million autosomal and X chromosome single-nucleotide polymorphisms (SNPs) in 18 759(More)
BACKGROUND Electronic medical records (EMR) provide a unique opportunity for efficient, large-scale clinical investigation in psychiatry. However, such studies will require development of tools to define treatment outcome. METHOD Natural language processing (NLP) was applied to classify notes from 127 504 patients with a billing diagnosis of major(More)
OBJECTIVE It has been suggested that there is a mechanism by which nonsteroidal anti-inflammatory drugs (NSAIDs) may interfere with antidepressant response, and poorer outcomes among NSAID-treated patients were reported in the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) study. To attempt to confirm this association in an independent(More)
A central aspect of the cerebellar cognitive affective syndrome is the dysregulation of affect that occurs when lesions involve the 'limbic cerebellum' (vermis and fastigial nucleus). In this case series we describe neuropsychiatric disturbances in adults and children with congenital lesions including cerebellar agenesis, dysplasia, and hypoplasia, and(More)
The authors present the cases of three patients in whom panic attacks and epilepsy appeared together. These cases illustrate various possible relationships between panic attacks and epilepsy. These relationships include panic attacks representing the aura of a complex partial seizure, panic attacks representing a manifestation of interictal behavior change,(More)
Atypical panic attacks include features such as focal paresthesias or sensory distortions, but attempts to demonstrate a relationship to partial seizures have been unsuccessful. Two patients with atypical panic attacks had attacks during EEG monitoring: one during a routine EEG in the EEG laboratory, the other at home during ambulatory monitoring. Focal(More)
This study used visual and auditory evoked potentials (VEP and AEP) to study low-level sensory processing in a group of 15 unmedicated subjects with obsessive-compulsive disorder (OCD) and 30 age-matched, gender-matched, and handedness-matched normal controls. EPs were recorded to flash (VEP) and binaural click (AEP) stimulation. OCD subjects were found to(More)
OBJECTIVE To quantify the impact of citalopram and other selective serotonin reuptake inhibitors on corrected QT interval (QTc), a marker of risk for ventricular arrhythmia, in a large and diverse clinical population. DESIGN A cross sectional study using electrocardiographic, prescribing, and clinical data from electronic health records to explore the(More)
The majority of patients with bipolar affective disorder will continue to have some recurrences of acute illness despite lithium maintenance. In a significant proportion, the frequency and severity of acute episodes necessitate the administration of adjunctive maintenance medications. Neuroleptic drugs are often used for this purpose, but anticonvulsant(More)
