Executive cognitive deficits in primary dystonia

Abstract: Primary dystonia is a disorder of movement for which no consistent pathophysiology has been identified; in the absence of evidence to the contrary, it is assumed to be cognitively benign. We have studied a clinically heterogeneous group of 14 patients with primary dystonia on a battery of neuropsychological tests. Despite well-preserved speed of information processing, language, spatial, memory and general intellectual skills relative to normal controls, we have identified a constellation of attentional-execut… Show more

“…Our patient sample of 38 is larger than most previously published studies (Ostrem et al, 2011;Taylor et al, 1991;Scott et al, 2003;Jahanashahi et al, 2003;Balas et al, 2006;Kleiner-Fisman et al, 2007;Vidalihet et al, 2005). Studies with similar size limitations and those with larger samples (up to n = 51) have also reported scattered impairments on tests of executive functioning (van Tricht et al, 2012;Bugalho et al, 2008;Romano et al, 2012).…”

“…Attention deficit was reported by recent studies of patients with different types of dystonia, including primary generalized dystonia and focal dystonia (Allam, Frank, Pereira, & Tomaz, 2007; Scott et al., 2003). Attention deficit may indicate the disruption of the dorsolateral‐prefrontal loop, which involves the striatum, thalamus and prefrontal cortex, regions showing altered functional activity and microstructural abnormalities in dystonia (Yang et al., 2013; Zoons, Booij, Nederveen, Dijk, & Tijssen, 2011).…”

“…It has been also difficult to determine the specific impact of perceptual, mnemonic and executive cognitive deficits on focal dystonia 12,13 . Executive functions are mental processes involved in the performance of goal-directed behavior whether expressed through a mental or a motor act 14 .…”
