As it had previously been demonstrated that there were reduced brain dopamine concentrations in monkeys who had been given polychlorinated biphenyls (PCBs) chronically, we hypothesized that organochlorine compounds in general, and PCBs in particular, might be important in the pathogenesis of Parkinson's disease (PD). In a study of caudate nucleus obtained(More)
The concentrations of organochlorine (OC) compounds in the substantia nigra (SN) were compared in Parkinson's disease (PD) with concentrations in brain from cortical Lewy body dementia (CLBD), Alzheimer's disease (AD), and nondemented nonparkinsonian controls (CON). The levels of the gamma isomer of hexachlorocyclohexane (gammaHCH, lindane) were(More)
Borderline personality disorder (BPD), is a condition that has a high mortality and is associated with much distress for the sufferers as well as with difficult management problems for health professionals. Taking emotional dysregulation as the core feature of BPD, the authors propose that the disorder arises from impaired modulation of subcortical inputs(More)
Patients with chronic schizophrenia were examined by nuclear magnetic resonance imaging of the brain. Subgroups of the syndrome with high positive or high negative symptom scores and ventricular dilatation were compared with each other and with normal controls in respect of regional spin lattice relaxation time (T1) changes. Significant differences were not(More)
Although psychotherapy is successful in altering emotional distress, the biological mechanism by which it achieves this has not been the subject of intensive neurobiological investigation. Mindful processing of emotion has been proposed [Mindfulness-Based Cognitive Therapy for Depression, The Guilford Press, New York, 2002] to be a key factor in prevention(More)
Proton NMR imaging of the brain is rapidly becoming established as a useful investigative tool in medicine. This paper examines the usefulness of the NMR parameters--spin-lattice relaxation time (T1) and proton density (PD)--in differentiating groups of patients with senile dementia of Alzheimer type (SDAT) and multi-infarct dementia (MID) from each other,(More)
BACKGROUND Progenitor cells (PCs) are mobilized in response to vascular injury to effect regeneration and repair. Recruitment of PCs requires intact nitric oxide (NO) synthesis by endothelial cells, and their number and activity correlate with cardiovascular disease risk burden and future outcomes. Whereas cardiovascular vulnerability exhibits a robust(More)
Evidence of efficacy in studies of post-traumatic conditions is largely derived from studies in which variables are kept to a minimum. Extrapolation of treatments from uncomplicated disorders to complex conditions may therefore be called evidence-based without being evidenced. Complex conditions with polysymptomatic presentations and extensive comorbidity(More)
Brainspotting is a psychotherapy based in the observation that the body activation experienced when describing a traumatic event has a resonating spot in the visual field. Holding the attention on that Brainspot allows processing of the traumatic event to flow until the body activation has cleared. This is facilitated by a therapist focused on the client(More)
This paper reviews the Window of Tolerance model of the long-term effects of the severe emotional trauma associated with childhood abuse, a model which can also be applied to adult trauma of sufficient severity to cause post-traumatic stress disorder, chronic dysthymic disorders and chronic anxiety disorders. Dysfunctional behaviours such as deliberate(More)
