This study examined the hypothesis that individuals with attention deficit hyperac‐ tivity disorder, predominantly inattentive type (ADHD-I), show both executive function (EF) deficits and non-EF deficits. A group with ADHD-I (n = 16) and a paired control group (n = 21) completed a battery of tasks covering the major domains of EF (planning, working memory, flexibility and inhibition) and non-E...

This Fact Sheet is based on a chapter to appear in the next edition of Dr. Barkley's textbook, Attention Deficit Hyperactivity Disorder: A Handbook for Diagnosis and Treatment (4 th edition). New York: Guilford Press. In press; expected publication date – December 2014. This chapter reviews the evidence for a second attention disorder that is distinct from yet overlaps with ADHD. Although this ...

OBJECTIVE To investigate whether patients diagnosed with amnestic mild cognitive impairment (MCI) have also impairment in attention/executive functions, and therefore to clarify whether all subcomponents of executive control are equally affected in MCI. BACKGROUND MCI refers to the transitional state between normal aging and dementia. Amnestic MCI is characterized by impaired episodic memory,...

OBJECTIVES Deficit in visuospatial functions can influence both simple and complex daily life activities. Despite the fact that visuospatial deficit was reported in schizophrenia, research on visuospatial functions as an independent entity is limited. Our study aims to elucidate the impact of visuospatial deficit in comparison with verbal deficit on global functioning and quality of life in the...

OBJECTIVES A deficit in facial emotion recognition was described in patients with Alzheimer disease (AD). However, this issue has been underexplored in subjects with amnestic mild cognitive impairment (a-MCI). Thus, the authors aimed to determine whether a deficit in facial emotion recognition is present in a-MCI phase and whether this is intensity dependent. A secondary aim was to investigate ...

We propose that brain energy deficit is an important pre-symptomatic feature of Alzheimer's disease (AD) that requires closer attention in the development of AD therapeutics. Our rationale is fourfold: (i) Glucose uptake is lower in the frontal cortex of people >65 years-old despite cognitive scores that are normal for age. (ii) The regional deficit in brain glucose uptake is present in adults ...
