Symptoms neuropsychological

Marttila et al. (1995) also examined the relationship between daily exposure to malodorous sulfur compounds (measured as total reduced sulfur [TRS]) from pulp production and experience of symptoms in a small population living in the vicinity of a pulp mill. The major components of the malodorous sulfur compounds are hydrogen sulfide, methyl mercaptan, and methyl sulfides. This work was initiated due to the observation that an unusually high short-term exposure to malodorous sulfur compounds (maximum 4-hour concentrations of hydrogen sulfide at 135 g/m3 [96 ppb]) led to a considerable increase in the occurrence of ocular, respiratory, and neuropsychological symptoms (Haahtela et al.

Subtle, often subclinical, neurological effects have been demonstrated in workers with relatively low blood lead levels, below 40-60 J,g/100ml blood. Performance of lead workers on various neuropsychological tests was mildly reduced, relative to a control group, at mean levels of 49 j,g/100ml blood and, in a prospective follow-up study, at levels between 30 and 45 pg/lOOml blood.In some of these studies, the lead-exposed workers reported significantly more complaints of nonspecific subjective symptoms, such as anxiety, depressed mood, poor concentration, and forgetfulness. However, a recent evaluation of 21 studies found inadequate evidence of decreased neu-robehavioral test performance in adults with cumulative low-level exposure to lead. In con-... 

Improvement can be determined by regular clinical assessment, patient self-report, and weekly use of subjective and objective symptom measures. It can commence very early in the ECT course. ECT should be continued until the patient no longer seems to be improving. The usual number of treatments required by young persons is similar to that required by adults (a mean of 6-12). Assessment of unwanted events should be made following each ECT administration by systematic inquiry of the common side effects or by use of specially developed scales such as the Columbia ECT Subjective Side Effects Schedule (Sackeim et al., 1987). Where possible, neuropsychological assessment should be per-... 

Stroke is a clinical diagnosis and the acute onset of focal neurological symptoms is the major indicator of stroke. Whereas typical stroke symptoms such as hemiparesis, amaurosis or dysarthria are easy to recognize, other stroke syndromes such as vertebrobasilar strokes or predominant neuropsychological manifestations are subject to misdiagnosis especially for non-neurologists. Misdiagnosis may be due to a non-vascular medical condition that simulates a stroke syndrome - a condition coined stroke mimicry . Or, a stroke may resemble another non-vascular clinical entity - a circumstance termed as stroke chameleon (Huff 2002). 

Palmer et al. (1999) focused on extrapyramidal symptoms (EPS) rather than TD and found that severity of EPS correlated with the severity of neuropsychological deficits, especially in the areas of learning and motor skills. Krausz et al. (1999) found a similar correlation between EPS and cognitive deficits on a self-rating scale. They believed the deficits were sufficient to cause potential difficulty with insight and everyday life skills.
