“…The association of cognitive dysfunction regarding the degree and prognosis of dysphagia with a stroke is well known [293031]. In addition, the relationship between cognitive deficits and dysphagia is significant in other central nervous system diseases such as dementia, mild cognitive impairment (MCI), and Parkinson disease.…”

ObjectiveTo investigate the characteristics and risk factors of dysphagia with the Videofluoroscopic Dysphagia Scale (VDS) using a videofluoroscopic swallowing study (VFSS) in patients with ruptured aneurysmal subarachnoid hemorrhage (aSAH).MethodsData of 64 patients presenting with first-ever ruptured aSAH were analyzed. Characteristics of dysphagia were evaluated using VFSS and all subjects were divided into a high (>47) and low risk group (≤47) by the VDS score. Clinical and functional parameters were assessed by medical records including demographics, hypertension and diabetes mellitus (DM), the Glasgow Coma Scale (GCS), the Hunt and Hess scale, endotracheal intubation, acute management modalities, as well as Korean version of the Mini-Mental Status Examination (K-MMSE) and Korean version of Modified Barthel Index (K-MBI). Radiologic factors identified the amount of hemorrhage, ventricular rupture, and aneurysmal location.ResultsAbout a half of the subjects showed oral phase abnormalities and the oral transit time was delayed in 46.8% of the patients. The pharyngeal transit time was also prolonged in 39.0% of the subjects and the proportion of penetration and aspiration observed was 46.8%. The parameters-GCS score (p=0.048), hemorrhagic volume (p=0.028), presence of intraventricular hemorrhage (p=0.038), and K-MMSE (p=0.007)-were predisposing factors for dysphagia in patients with aSAH.ConclusionAbnormalities in the oral phase were more prominent in patients with aSAH than in those with other types of stroke. The risk factors associated with dysphagia persisting over 6 months after stroke onset were the initial GCS, hemorrhage volume, presence of intraventricular hemorrhage, and cognitive status as measured by the K-MMSE.

“…Previous studies do not show a relationship between ischemic stroke and dysphagia, describing only suggestive findings of OD after neurological impairment (16,18) . However, several studies have indicated that this type of stroke is the most prevalent in the affected population (19,(22)(23)(24) . Similarly, this was also observed in our study with varying degrees of swallowing impairment.…”

“…Some studies have presented the NIHSS score between 11 and 12 as the cut-off point for risk of dysphagia (10) . The use of the NIHSS is also suggested as an ideal marker in several studies that addressed the consequences of stroke (5,9,10,17,24,29) . Another study assessed the NIHSS score as a predictor for the use of percutaneous endoscopic gastrostomy (PEG) in hospitalized patients with acute ischemic stroke.…”

Purpose: To associate the degree of biomechanical impairment in the swallowing process with the severity (National Institute of Health Stroke Scale -NIHSS) and type of neurological injury in patients post stroke. Methods: A cross-sectional, descriptive study conducted with 42 patients (22 females), aged 65.7 years on average diagnosed with stroke. All patients underwent clinical neurological evaluation and application of the NIHSS in the first 48 hours after stroke. The swallowing function was evaluated using the Functional Oral Intake Scale (FOIS) and the Protocol for the Investigation of Oropharyngeal Dysphagia in Adults. The Fisher's Exact Probability Test was used to assess the correlation between the degree of swallowing impairment and the severity (NIHSS score) and type of stroke. The study results were statistically analyzed at 5% significance level (p≤0.05). Results: 92.9% of the patients presented ischemic stroke; 59.5% presented impairment of the anterior cerebral circulation. Statistically significant correlation was found between the neurological scale (NIHSS) scores and the swallowing impairment scale (p=0.016). Conclusion: An association between stroke severity and oropharyngeal dysphagia severity was observed. A high proportion of patients with ischemic stroke with circulation affected in the anterior cerebral region presented severe oropharyngeal dysphagia. No statistically significant correlation was observed between the FOIS scale and stroke severity.

“…Yet, the lesion localization as a predictor of dysphagia has recently obtained more interest. While some studies have detected an association between lesion site and dysphagia,[22] others have not found a significant relationship between the location of lesion and presence of dysphagia. [2324]…”

Brain regions involved in swallowing: Evidence from stroke patients in a cross-sectional study

Background:Limited data available about the mechanisms of dysphagia and areas involving swallow after brain damage; accordingly it is hard to predict which cases are more likely to develop swallowing dysfunction based on the neuroimaging. The aim of this study was to investigate the relationship between brain lesions and dysphagia in a sample of acute conscious stroke patients.Materials and Methods:In a cross-sectional study, 113 acute conscious stroke patients (69 male mean [standard deviation (SD)] age 64.37 [15.1]), participated in this study. Two neurologists and one radiologist localized brain lesions according to neuroimaging of the patients. Swallowing functions were assessed clinically by an expert speech pathologist with the Mann Assessment of Swallowing Ability (MASA). The association of brain region and swallowing problem was statistically evaluated using Chi-square test.Results:Mean (SD) MASA score for the dysphagic patients was 139.61 (29.77). Swallowing problem was significantly more prevalent in the right primary sensory (P = 0.03), right insula (P = 0.005), and right internal capsule (P = 0.05).Conclusion:It may be concluded from these findings that the right hemisphere lesions associated with occurring dysphagia. Further studies using more advanced diagnostic tools on big samples particularly in a perspective structure are needed.
