This report reviews the state of the literature and opportunities for research related to "executive control function" (ECF). ECF has recently been separated from the specific cognitive domains (memory, language, and praxis) traditionally used to assess patients. ECF impairment has been associated with lesions to the frontal cortex and its basal(More)
Psychiatric disorders frequently complicate recovery and rehabilitation from traumatic brain injury (TBI). This study reviews the literature from 1978 to 2006 on psychosis, depression, posttraumatic stress disorder, mania, and aggression following nonpenetrating TBI. The studies were reviewed using the American Academy of Neurology's criteria for(More)
This report reviews the state of the literature and opportunities for research related to the cognitive correlates of functional status. The prediction of functional capacity on the basis of cognitive test performance is an important aspect of neuropsychological assessment. Moreover, functional impairment or "disability" is an essential part of dementia(More)
MODERN PSYCHIATRIC NOSOLOGIES SEPARATE CATATONIA ALONG THE LINES OF PRESUMED ETIOLOGY: bipolar, major depression, schizophrenia, and/or due to a general medical condition. Catatonic signs have always possessed significant diagnostic, therapeutic, and prognostic value. Kahlbaum's description of this syndrome in his monograph "Katatonia" included careful(More)
Pathological laughing and crying (PLC) is a clinical condition that occurs in patients with various neurological disorders. It is characterized by the presence of episodic and contextually inappropriate or merely exaggerated outbursts of laughter and/or crying without commensurate feelings. This review provides an in depth analysis of the neuroanatomy of(More)
Involuntary emotional expression disorder (IEED) includes the syndromes of pathological laughing and crying (PLC) and emotional lability (EL). Review of the lesion, epilepsy, and brain stimulation literature leads to an updated pathophysiology of IEED. A volitional system involving frontoparietal (primary motor, premotor, supplementary motor, posterior(More)
We studied subjects with focal subcortical lesions (SCLs) and investigated the frequency of pallidal lesions in secondary major depression (secondary MD) presenting after but not before lesion onset. Forty-five subjects were selected for focal subcortical lesions (SCLs) from 10,000 hospital magnetic resonance imaging (MRI) films. SCLs were ascertained by(More)
BACKGROUND Dextromethorphan (DM) is a widely-used antitussive. DM's complex central nervous system (CNS) pharmacology became of interest when it was discovered to be neuroprotective due to its low-affinity, uncompetitive N-methyl-D-aspartate (NMDA) receptor antagonism. REVIEW SUMMARY Mounting preclinical evidence has proven that DM has important(More)
The authors investigated the prevalence of DIS-ascertained DSM-III psychiatric disorders occurring in 28 patients with dystonia and 28 patients with Parkinson's Disease (PD). In patients with dystonia, lifetime prevalences of major depression (25.0%), bipolar disorder (7.1%), atypical bipolar disorder (7.1%), social phobia (17.9%), and generalized anxiety(More)
It was previously hypothesized that dextromethorphan (DM) and dextrorphan (DX) may possess antidepressant properties, including rapid and conventional onsets of action and utility in treatment-refractory depression, based on pharmacodynamic similarities to ketamine. These similarities included sigma-1 (σ(1)) agonist and NMDA antagonist properties, calcium(More)
