Does it fit? – Impaired affordance perception after stroke

Publication date: 8 January 2018 Source:Neuropsychologia, Volume 108 Author(s): Jennifer Randerath, Lisa Finkel, Cheryl Shigaki, Joe Burris, Ashish Nanda, Peter Hwang, Scott H. Frey Affordance perception comprises the evaluation of whether our given bodily capabilities and properties of the environment allow particular actions. Typical impairments after left brain damage in motor cognition as well as after right brain damage in visuo-spatial abilities may affect the evaluation of whether interactions with objects are possible. Further it is unclear whether deficient motor function is accounted for when deciding upon action opportunities. For these purposes we developed a paradigm with two tasks that differ in their type of demands on affordance perception and tested it in healthy young adults (Randerath and Frey, 2016). Here, we applied one of these two tasks in stroke patients and age matched healthy participants. A sample of 34 stroke patients with either left (LBD) or right brain damage (RBD) and 29 healthy controls made decisions about whether their hands would fit through a defined horizontal aperture presented in various sizes, while they remained still. Data was analyzed using a detection theory approach and included criterion, perceptual sensitivity and diagnostic accuracy as dependent variables. In addition we applied modern voxel based lesion analyses to explore neural correlates. Compared to controls, both patient groups demonstrated lower perceptual sensitivity. ...

CONCLUSIONS: PA use may reduce initial stroke severity in AT stroke and the risk of END, and can improve functional outcome at three months irrespective of stroke subtypes. PMID: 30429408 [PubMed - as supplied by publisher]

CONCLUSION: Mechanical inspiration and expiration exercise had a therapeutic effect on velopharyngeal incompetence in subacute stroke patients with dysphagia. This therapy is easy to provide clinically and could be a useful therapeutic strategy for velo-pharyngeal incompetence with dysphagia in patients with stroke.

Authors: Hildick-Smith D, Turner M, Shaw L, Nakum M, Ó Hartaigh B, Evans RM, Rhodes JF, Sondergaard L, Kasner SE Abstract AIMS: Percutaneous closure of a patent foramen ovale (PFO) is known to lower the risk of recurrent stroke in patients with a cryptogenic stroke. However, the economic implications of transcatheter PFO closure are less well known. From a UK payer perspective, we performed a detailed economic appraisal of PFO closure for prevention of recurrent ischemic stroke in patients with a PFO who had experienced a cryptogenic stroke. MATERIALS AND METHODS: A Markov cohort model was constructed us...

We present a 44-year-old man admitted for vasospastic angina that suffered a right middle cerebral artery (MCA) occlusion after a cardiac catheterization. Mechanical thrombectomy was indicated and complete arterial recanalization was achieved. The material obtained showed a fragment of a healthy artery. Partial radial endarterectomy and cerebral embolization may be a rare complication of cardiac catheterization.

AbstractHorizontal gaze deviation (HGD) on computed tomography (CT) is considered a useful finding for detecting ischemic stroke. To enhance its availability, we studied the criterion suitable for visual determination and lesion characteristics. The clinical records of 327 ischemic stroke patients and 193 non-stroke controls were reviewed with measurements of eye deviation angles on CT. Initially, the HGD criterion defined by the minimum angle in unidirectionally deviated eyes was determined from control data. Subsequently, patients were classified by infarcted arterial territory and stroke subtype, and compared with contr...

Background: In the United States, stroke continues to be the cause for long-term disability. Of the patients with a first stroke, up to 75% will experience post-stroke fatigue (PSF) in the first year following stroke. PSF is one of the most disabling symptoms in stroke survivors; it decreases quality of life, increases mortality, and is a barrier to stroke rehabilitation. Given the incidence of stroke and the prevalence and detrimental impact of PSF on quality of life, independent living, and overall survival, efficient management of PSF must be a priority in stroke rehabilitation. The cause of PSF remains unknown. The bur...

Edwards Lifesciences (NYSE:EW) said today it won CE Mark approval in the European Union for its Sapien 3 Ultra transcatheter aortic valve replacement system intended for patients with severe, symptomatic aortic stenosis. Despite winning a CE Mark, Edwards said that the new valve will not be launched in Germany due to a preliminary injunction from rival Boston Scientific (NYSE:BSX). The company said that “the German court will hold a full hearing on the merits of the dispute” mid-next year, and that it is hopeful it will prevail. The company said it will introduce the Sapien 3 Ultra in the rest of Euro...
