We reported the two cases with bulbar-onset ALS showing isolated agraphia without overt dementia and aphasia. Patient 1 was a 69-year-old man and patient 2 was an 81-year-old woman, and both were right-handed. Each patient developed dysarthria as an initial symptom followed by dysphagia, and neurological examinations showed atrophy and fasciculation of the tongue with upper and lower motor-neuron involvement of the extremities. These characteristic features with electromyographic evidence including widespread acute and chronic denervation led to a diagnosis of bulbar-onset ALS. Around 1 year after the onset of ALS, dysarthria was mild enough to allow oral communication enabling the determination that aphasia was absent with well preserved confrontation naming, repetition, reading and comprehension. The patients were polite without abnormal behavior or character change, and their general intelligence was also well preserved with excellent scores on the Mini Mental State Examination (30 and 27 points for patients 1 and 2, respectively) and Frontal Assessment Battery (16 points for each patient). However, spontaneous writing and dictation revealed abundant writing errors characterized by omission of kana letters and paragraphia of kana and kanji letters in both patients. Some syntactic errors were also observed in writing but in spoken language. A letter-number effect on writing errors was observed in patient 1. Copying of letters or words was intact and structure and orientation of written letters was well preserved, indicating the absence of constructional, apraxic or spatial feature of agraphia. Single photon emission computed tomography demonstrated reduced uptake in the bilateral frontotemporal lobes, predominantly in the left hemisphere, with less evident alternation in magnetic resonance imaging. Our results suggest that patients with bulbar-onset ALS may develop isolated agraphia as a single-domain cognitive impairment, preceding the clinical manifestation of aphasia or dementia. We speculate that the main responsible region might be the posterior part of the middle and inferior frontal gyri including Exner's writing center and Broca's area beyond the primary motor cortex.

Objective: To assess swallowing progression and its association with the extension of brain damage and cognitive impairment during the acute phase of ischemic stroke. Methods: Cross-sectional, observational study with 50 patients, who were admitted to a Stroke Unit with cerebral ischemia, with a maximum stroke time of 24 h. The following clinical tools were used: National Institutes of Health Stroke Scale, Mini-Mental State Examination, Frontal Battery Assessment, and the Alberta Stroke Program Early CT Score for neuroimaging. The Gugging Swallowing Screen and the Functional Oral Intake Scale were used to assess swallowing. The patients were assessed at three different time-points: at hospital admission, after 72 h of hospitalization, and at hospital discharge. Results: The mean age of patients was 65.5 years. The frequency of dysphagic patients was 50.0%, 18.0%, and 12.0% at admission, after 72 h of hospitalization, and at discharge, respectively. Scores on the Frontal Battery Assessment and the Alberta Stroke Program Early CT Score were associated with dysphagia progression. Conclusion: Dysphagia is a common complication in the acute phase of stroke, and is associated with the extension of brain damage and cognitive impairment.

We tested whether karaoke training improves cognitive skills and reduces the risk of physical function impairments. We conducted a single-blinded randomized controlled trial in 26 elderly participants at residential care facilities, who were generally healthy or required the lowest level of care. Participants were near the threshold for mild cognitive impairment with the Montreal Cognitive Assessment (MoCA) and close to the sarcopenia cut-off with the skeletal muscle mass index. Pulmonary function as measured with spirometry and tongue strength were used as markers for physical functions affected by sarcopenia. Karaoke training occurred once a week for two hours, with an hour of homework assigned weekly. Karaoke training significantly improved the Frontal Assessment Battery at bedside (FAB) compared with an active control group receiving scratch art training (F = 8.04, permutation p-value = 0.013). Subscore improved with inhibitory control (F = 7.63, permutation p-value = 0.015) and sensitivity to interference (F = 11.98, permutation p-value = 0.001). We observed improved tongue pressure (F = 4.49, permutation p-value = 0.040) and pulmonary function by a greater increase in FIV1 (F = 5.22, permutation p-value = 0.047). Engaging elderly people, especially those in care homes, with karaoke training exercises that are moderately physically challenging may be a key to slowing cognitive decline and preventing dysphagia by sarcopenia.
