Studies, while limited, suggest that prenatal exposure to marijuana could cause harm to children's executive functioning, including concentration, attention, impulse control and problem-solving.
This instrument assesses different cognitive domains: attention and concentration, executive functions, memory, language, visuoconstructional skills, conceptual thinking, calculations, and orientation [ 11].
Early exposure to adverse social and nutritional conditions appear detrimental to semantic memory, learning, concentration, executive control and language among adults, independent of adulthood educational achievement.
Sixteen neuropsychological tests examining the main cognitive domains (intelligence, memory, attention and concentration, executive functions and abstract reasoning) were administered by a neuropsychologist.
Although chemotherapy can offer long-term survival for patients with cancer, recent reports [ 1] have revealed that it may induce cognitive dysfunction, such as deficits in attention, concentration, executive function, and processing speed.
For instance, depressed individuals often have cognitive deficits in concentration, executive function and over-general memory (Williams et al. 2000) and individuals with PTSD often also present with over-general memory (Schönfeld and Ehlers 2006).
To assess cognition in a complementary manner to the ADAS-cog, a cognitive test battery composed of the Digit Span from the Wechsler Memory Scale – Third Edition [ 16], the Concept Shifting Test [ 17], the Letter Digit Substitution Test [ 18], and Category Fluency [ 19] was administered to measure attention and concentration, executive function, processing speed, and semantic memory, respectively.
Many different tasks that require concentration, executive activity and recruitment of various brain areas when the task is new can be automated with experience to a point where the task can be completed efficiently with only a minimal expenditure of metabolic activity [ 92].
However, it may be noted that even with other patient groups (e.g. HIV: [ 79]), where CSF HVA levels were <50% of the non-affected controls, correlations were restricted to response slowing on tests of executive attention and concentration and unrelated to memory performance.
WHILE some REIT's have emphasized geographic diversification, Stephen L. Green, the chief executive of SL Green Realty Corporation, concentrates on concentration.
