BACKGROUND Previous structural magnetic resonance (MR) research in patients with posttraumatic stress disorder (PTSD) has found smaller hippocampal volumes in patients compared with control subjects. These studies have mostly involved subjects who have had PTSD for a number of years, such as war veterans or adult survivors of childhood abuse. Patients with(More)
This study examined whether patients with temporal lobe epilepsy (TLE) and ictal fear (IF) show emotion recognition deficits similar to those associated with amygdala damage. Three groups of patients (13 with TLE and IF, 14 with TLE and nonfear auras (non-IF), and 10 with idiopathic generalized epilepsy (IGE)) completed tests of visual and face processing,(More)
BACKGROUND The memory deficits in patients with temporal lobe epilepsy (TLE) are associated with epileptogenic lesions of the temporal lobes, especially hippocampal sclerosis. Memory deficits have been extensively studied in TLE, but the presence of pre-existing temporal lobe abnormality has confounded studies on the relationship between memory dysfunction(More)
Gluten sensitivity can manifest with ataxia. The metabolic status of the cerebellum was investigated in 15 patients with gluten ataxia and 10 controls using proton MR spectroscopy. Significant differences were present in mean N-acetyl aspartate levels at short echo time and N-acetyl aspartate/choline ratios at long echo time between the patient and control(More)
We have previously reported a greater than 50% prevalence of structural brain abnormalities in children within 2 weeks of first complicated early childhood convulsion, including significant hippocampal asymmetry unrelated to edema. In a 6-year follow-up study, 8 of the original 17 subjects were reimaged to determine any developments in hippocampal(More)
The substantia nigra (SN) pars compacta is arranged somatotopically. Symptoms of idiopathic Parkinson's disease (IPD) are caused by a lesion in this nucleus, which spreads in a stereotyped spatio-temporal pattern during the course of the disease. We investigated the order of somatic symptom progression in a group of 30 patients with IPD to determine if(More)

Resumen Since its emergence in the 70s, the Dual Process Model (DPM) has gained wide popularity in different fields of psychology, including the study of addictions. According to this model, there are two cognitive systems: one explicit, conscious and controllable; and another implicit, automatic and linked to intuition and affection. The DPM has been used(More)
OBJECTIVES Suspected seizures are a common reason for emergency calls to ambulance services. Prehospital management of these patients is an important element of good quality care. The aim of this study, conducted in a regional ambulance service in the UK, was to quantify the number of emergency telephone calls for suspected seizures in adults, the(More)
The stereological method of cross-counting based on the Cavalieri principle is widely used in neuroimaging to estimate the volume of cerebral structures. Although superficially simple, the stereological technique is validated by arcane mathematical proofs, so the cross size is determined by most investigators on a pragmatic basis with the assumption that(More)
One hundred seventy-four youthful psychiatric inpatients were given the Draw-A-Person Test (DAP) as part of an assessment battery. Sex of person drawn was compared to subject's sex, Achenbach aggression and delinquency scores, and scores on Children's Inventory of Anger and Nowicki-Strickland Locus of Control Scale. The sex of the person drawn was also(More)
