Cognitive and motor slowing in Alzheimer's disease and geriatric depressionR D Nebes
Department of Psychiatry, Western Psychiatric Institute and Clinic, University of Pittsburgh School of Medicine, PA 15213, USA
J Int Neuropsychol Soc 4:426-34. 1998..Thus, this study suggests that AD produces a slowing in both cognitive and motor processes, whereas depression results solely in a motor retardation...- The nature and determinants of neuropsychological functioning in late-life depressionMeryl A Butters
Department of Psychiatry, University of Pittsburgh Medical Center, PA, USA
Arch Gen Psychiatry 61:587-95. 2004..Further studies of neuropsychological functioning in remitted LLD patients are needed to parse episode-related and persistent factors and to relate them to underlying neural dysfunction... - Instantiation of semantic categories in sentence comprehension by Alzheimer patientsR D Nebes
Department of Psychiatry, University of Pittsburgh School of Medicine, USA
J Int Neuropsychol Soc 5:685-91. 1999..Results showed that Alzheimer patients were highly accurate at instantiating even objects they could not name. This is consistent with a relative preservation of semantic knowledge about concrete objects in Alzheimer patients... - Relationship of deep white matter hyperintensities and apolipoprotein E genotype to depressive symptoms in older adults without clinical depressionR D Nebes
Western Psychiatric Institute and Clinic, Thomas Detre Hall, 3811 O Hara St, Pittsburgh, PA 15213, USA
Am J Psychiatry 158:878-84. 2001.... - Dual-task performance in depressed geriatric patientsR D Nebes
Department of Psychiatry, University of Pittsburgh School of Medicine, Pittsburgh, PA 15213, USA
Psychiatry Res 102:139-51. 2001.... - Longitudinal increase in the volume of white matter hyperintensities in late-onset depressionRobert D Nebes
Department of Psychiatry, WPIC, University of Pittsburgh School of Medicine, 3811 O Hara Street, Pittsburgh, PA 15213, USA
Int J Geriatr Psychiatry 17:526-30. 2002..However, at present there is little evidence that a longitudinal increase in WMH burden within an individual is associated with the onset of a late-life depression... - Persistence of cognitive impairment in geriatric patients following antidepressant treatment: a randomized, double-blind clinical trial with nortriptyline and paroxetineRobert D Nebes
Intervention Research Center for the Study of Late Life Mood Disorders, Department of Psychiatry, Western Psychiatric Institute and Clinic, University of Pittsburgh Medical Center, Pittsburgh, PA 15213, USA
J Psychiatr Res 37:99-108. 2003..The present results suggest that cognitive dysfunction persists in older depressed patients even after their mood disorder has responded to antidepressant medications... - Serum anticholinergic activity, white matter hyperintensities, and cognitive performanceR D Nebes
Department of Psychiatry, University of Pittsburgh Medical Center, Pittsburgh, PA, USA
Neurology 65:1487-9. 2005.... - The relation of White Matter Hyperintensities to implicit learning in healthy older adultsH J Aizenstein
Department of Psychiatry, University of Pittsburgh School of Medicine, Pittsburgh, PA 15213, USA
Int J Geriatr Psychiatry 17:664-9. 2002.... - Complementary category learning systems identified using event-related functional MRIH J Aizenstein
University of Pittsburgh Medical School, Western Psychiatric Institute and Clinic, 3811 O Hara Street, Pittsburgh, PA 15213, USA
J Cogn Neurosci 12:977-87. 2000..Moreover, in both the implicit and explicit conditions a similar pattern of decreased activation was found in parietal regions. This commonality suggests that these dissociable systems also operate in parallel... - Hypothyroidism and cognition: preliminary evidence for a specific defect in memoryL A Burmeister
Department of Medicine, University of Pittsburgh School of Medicine, Pennsylvania, USA
Thyroid 11:1177-85. 2001.... - Executive functioning, illness course, and relapse/recurrence in continuation and maintenance treatment of late-life depression: is there a relationship?Meryl A Butters
Intervention Research Center for Late Life Mood Disorders, Western Psychiatric Institute and Clinic, Department of Psychiatry, University of Pittsburgh Medical Center, USA
Am J Geriatr Psychiatry 12:387-94. 2004..The authors tested the hypothesis that impaired executive functioning leads to high rates of relapse and recurrence in late-life depression... - The relation of white matter hyperintensities to cognitive performance in the normal old: education mattersRobert D Nebes
University of Pittsburgh Medical Center, Pennsylvania, USA
Neuropsychol Dev Cogn B Aging Neuropsychol Cogn 13:326-40. 2006..This is consistent with recent concepts of cognitive reserve, but does raise a question as to the underlying source of the cognitive decrement found in the sort of well-educated elders typically used in cognitive-aging studies... - Serum anticholinergic activity and motor performance in elderly personsRobert D Nebes
Department of Psychiatry, University of Pittsburgh Medical Center, Pennsylvania, USA
J Gerontol A Biol Sci Med Sci 62:83-5. 2007..Medications prescribed to elderly persons often have an anticholinergic effect, as do many commonly used over-the-counter drugs. Anticholinergic medications are known to produce psychomotor slowing, especially in older persons... - Prefrontal and striatal activation in elderly subjects during concurrent implicit and explicit sequence learningHoward J Aizenstein
Western Psychiatric Institute and Clinic, University of Pittsburgh School of Medicine, Department of Psychiatry, 3811 O Hara Street, Pittsburgh, PA 15213, USA
Neurobiol Aging 27:741-51. 2006..Moreover, these changes are observed during an implicit task, and thus do not seem to be mediated by awareness...
