Effects of a Cycling Dual Task on Emotional Word Choice in Parkinson’s Disease

Congratulations to Drs Okun & Hass on the publication of “Effects of a Cycling Dual Task on Emotional Word Choice in Parkinson’s Disease.”  This article was published in the May issue of the Journal of Speech, Language and Hearing Research.

 

Abstract

Purpose

Individuals with Parkinson’s disease (PD) demonstrate language- and emotion-related impairments; however, emotional language production has received little attention within the literature despite the fact that deficits could significantly impact one’s daily interactions with loved ones and others. Multitasking (i.e., dual tasking), specifically while completing language tasks, is a common everyday occurrence and typically impacts performance on 1 or both tasks. This study compared emotional word use during discourse production in individuals with PD and healthy older adults (HOAs) under single- and dual-task conditions.

Method

Participants completed a discourse task while sitting in a quiet room and while stationary cycling. Discourse output was analyzed along several emotional and intellectual language dimensions obtained from the Linguistic Inquiry and Word Count program (Pennebaker, Booth, & Francis, 2007).

Results

Groups did not differ on any outcome measure in the single-task condition. However, HOAs produced a higher percentage of words associated with affective processes and positive emotion while completing the dual-task condition, whereas the PD group exhibited a decrease in production of these words. Compared to the single-task condition, during cycling, individuals with PD also produced a lower percentage of inhibition-related words.

Conclusions

These results suggest that cycling, like other types of exercise, improves mood as manifested in discourse word choice in HOAs; however, it may lead to reduced use of emotional words in individuals with PD. Expressing emotion may also be more difficult in those with PD than in HOAs and, therefore, easily disrupted in distracting circumstances.

UPI: Kids with psych disorders most likely to take dangerous viral challenges

The “choking game” — and other clearly ill-advised and dangerous internet challenges — leave many parents wondering what drives teens to take the bait and participate. Now, a new study suggests that an underlying psychological disorder may be one reason why some kids jump at online dares such as the “Bird Box” challenge, where people walk around blindfolded, and the Tide Pod challenge, daring people to eat laundry detergent.

The emerging influential role of microglia in neurology

In her most catchily titled book, The Angel and the Assassin , Donna Jackson Nakazawa highlighed nerve cells which have hitherto been very little acknowledged – microglia . Long ignored as bit players in the big league of the nervous system, Nakazawa colourfully illustrated what many neuroscientists are beginning to realise: the small size of microglia belies their huge influence ; m icroglia are, after all, the defence force of the nervous system, protecting the brain from microbial invaders . In keeping with their small size, their role is to surreptitiously  present the antigens of invading bugs to T cells , the toffs who actually carry out the final hatchet job . It is therefore not surprising that any dysfunction of microglia will come with significant clinical consequences .  By GerryShaw – Own work , CC BY-SA 3.0 , Link The most important clinical fallout of dysfunctional microglia appears to be the emergence of dementia. It is indeed spec...
