#Self-Funded Rehabilitation and Therapist Education at Stroke Lab Arousal and attention have a close relationship that is necessary to maintain cognitive function. Arousal refers to the general activation or alertness of the brain, while attention refers to the ability to selectively focus on a particular stimulus or task. Research has shown that there is a strong relationship between arousal and attention disorders. Arousal affects attention, with low arousal levels associated with poorer attention and high arousal levels associated with better attention. In addition, attention disorders such as Attention Deficit Hyperactivity Disorder (ADHD) often have abnormalities in arousal regulation. One study by Lugo et al. (2019) showed that children with ADHD have lower cortical arousal compared to typically developed children, which is associated with poorer attention. Another study by Robertson et al. (2013) also showed that sleep deprivation, which is known to affect arousal, leads to poorer attention. In other words, arousal and attention are closely related, and if one is impaired, the other may also be affected. Understanding the interplay between these two concepts is important to develop effective treatments for disorders such as ADHD. Several studies have been conducted on the relationship between post-stroke arousal and hemispatial neglect, a typical example of attention disorder. In particular, it has been shown that the relationship between arousal and hemispatial neglect differs depending on the damaged hemisphere. It has been reported that in patients after left hemisphere damage, the lower the degree of arousal, the more severe the degree of hemispatial neglect. On the other hand, in patients after right hemisphere damage, no clear correlation was found between the degree of arousal and the degree of hemispatial neglect. According to one paper, the relationship between the degree of arousal and the degree of hemispatial neglect in patients after left hemisphere damage may be explained by a pathophysiological mechanism. According to this paper, in patients after left hemisphere damage, the damage to the cerebral cortex spreads, the activation of the right parietal lobe decreases, and signal transmission from the right parietal lobe is inhibited. As a result, information processing regarding the left hemispace decreases, which may cause hemispatial neglect. References: Karnath, HO (2002).
