The extent to which Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms (i.e., inattention, hyperactivity/impulsivity) are associated with ADHD-related cognitive impairments has yet to be understood. This study sought to examine between-group differences in activity level, performance on a sustained attention task and objectively measured attention, while controlling for anxiety and depression severity in a sample of adults with and without ADHD (N = 26). High precision actigraphs and behavioral codes of visual attention to task were used to examine the extent to which activity level and visual attention to task are related to performance on a sustained attention task (i.e., Continuous Performance …

Developmentally inappropriate and impairing impulsive behaviors are often seen in attention-deficit/hyperactivity disorder (ADHD). One method for objectively assessing impulsivity is the Choice-Delay Task (C-DT) which presents repeated opportunities to choose between a smaller, sooner (SS) or larger, later (LL) reward. A preference for the SS reward that results in less total reward is considered impulsive. Many studies have found that participants diagnosed with ADHD choose the SS reward more than typical controls. However, less is known about the effects of different types of rewards, or the comparative performance of certain subgroups, such as children diagnosed with ADHD Predominantly Inattentive Type …

Dopamine And Glutamate Dysfunction In A Rodent Model Of Attention-Deficit/Hyperactivity Disorder: Implications For Future Neuropharmacology, Erin M. Miller
Theses and Dissertations--Neuroscience
Attention-deficit/hyperactivity disorder (ADHD) is one of the most common disorders of childhood. It is theorized to be caused by catecholamine dysfunction in the striatum (Str) and frontal cortex (FC). The spontaneously hypertensive rat (SHR) has been used as a model for ADHD because of its attention deficits, impulsiveness, and hyperactivity. Prior studies of dopamine (DA) in the Str and FC have revealed conflicting results in the SHR compared to control, indicative of a need for a better understanding of DA dynamics in this model. In addition to the DA hypothesis, studies have begun implicating glutamate in the etiology of ADHD. …
