Pain is a common problem faced by Parkinson's disease (PD) patients. Despite its impact and disabling effects pain is still frequently overlooked. In this study we analyze a representative sample of peer reviewed literature for the prevalence and types of pain in PD, the impact and significance of pain in the quality of life of the PD patient and the(More)
BACKGROUND Many patients with restless legs syndrome (RLS) and Parkinson's disease (PD) report having pain, however, the impact of the combination of PD and RLS on pain has not been analyzed extensively. The objective of this study was to explore the potential relationship between RLS and pain in individuals with and without PD, the prevalence of RLS in PD,(More)
OBJECTIVE To develop a virtual reality platform that would serve as a functionally meaningful measure of cognition in schizophrenia and that would also complement standard batteries of cognitive tests during clinical trials for cognitive treatments in schizophrenia, be amenable to human neuroimaging research, yet lend itself to neurobiological comparison(More)
Schizophrenia is a heterogeneous disorder characterized by numerous diverse signs and symptoms. Individuals with prominent, persistent, and idiopathic negative symptoms are thought to encompass a distinct subtype of schizophrenia. Previous work, including studies involving neuropsychological evaluations, has supported this position. The present study sought(More)
Among the constellation of symptoms that characterize schizophrenia, negative symptoms have emerged as a critical feature linked to the functional impairment experienced by affected individuals. Despite advances in our understanding of the role of negative symptoms in the illness, effective treatments for these debilitating symptoms have remained elusive.(More)
SETTING The Aga Khan University Hospital, in Karachi, Pakistan, is a 650-bed university teaching hospital. OBJECTIVES There is little data from Pakistan on the awareness and application of the World Health Organization (WHO)'s tuberculosis treatment guidelines among physicians. This study evaluates physician compliance with these guidelines. DESIGN A(More)
BACKGROUND The Heinrichs-Carpenter Quality of Life Scale (QLS) is the most extensively used real-world community functioning scale in schizophrenia research. However, the extensive time required to administer it and the inclusion of items that overlap conceptually with negative symptoms limit its use across studies. The present study examined the validity(More)
Young onset Parkinson's disease patients, typically aged 21 to between 40 and 55, have symptomatology similar to regular onset patients. Despite this, we suspect that physicians take longer to diagnose young onset patients since Parkinson's disease is ruled out due to the younger age. The history prior to diagnosis of 14 young onset patients (within 21 to(More)
BACKGROUND Although many comprehensive batteries exist to evaluate the nature and degree of cognitive impairments in patients with schizophrenia, short batteries hold promise for rapidly screening and estimating deficits in global cognition. Recently, the Brief Neurocognitive Assessment (BNA) was established and has been shown to have similar validity and(More)
Social cognition, referring to one's ability to perceive and process social cues, is an important domain in schizophrenia. Numerous studies have demonstrated that patients with schizophrenia have poorer performance on tests assessing social cognition relative to healthy comparison participants. However, whether variables such as motivation are related to(More)
