Treatment of post-stroke dysphagia with repetitive transcranial magnetic stimulation.

Research Abstract
Abstract BACKGROUND: Up to one-third of patients experience swallowing problems in the period immediately after a stroke. OBJECTIVE: To investigate the therapeutic effect of repetitive transcranial magnetic stimulation (rTMS) on post-stroke dysphagia. MATERIALS AND METHODS: Twenty-six patients with post-stroke dysphagia due to monohemispheric stroke were randomly allocated to receive real (n = 14) or sham (n = 12) rTMS of the affected motor cortex. Each patient received a total of 300 rTMS pulses at an intensity of 120% hand motor threshold for five consecutive days. Clinical ratings of dysphagia and motor disability were assessed before and immediately after the last session and then again after 1 and 2 months. The amplitude of the motor-evoked potential (MEP) evoked by single-pulse TMS was also assessed before and at 1 month in 16 of the patients. RESULTS: There were no significant differences between patients who received real rTMS and the sham group in age, hand grip strength, Barthel Index or degree of dysphagia at the baseline assessment. Real rTMS led to a significantly greater improvement compared with sham in dysphagia and motor disability that was maintained over 2 months of follow-up. This was accompanied by a significant increase in the amplitude of the oesophageal MEP evoked from either the stroke or non-stroke hemisphere. CONCLUSION: rTMS may be a useful adjunct to conventional therapy for dysphagia after stroke.

Dual-Hemisphere Repetitive Transcranial
Magnetic Stimulation for Rehabilitation of
Poststroke Aphasia: A Randomized, Double-
Blind Clinical Trial

Research Abstract
Background. Recent neuroimaging studies on poststroke aphasia revealed maladaptive cortical changes in both hemispheres, yet their functional contribution in language recovery remains elusive. The aim of this study was to evaluate the long-term efficacy of dual-hemisphere repetitive transcranial magnetic stimulation (rTMS) on poststroke aphasia. Methods. Thirty patients with subacute poststroke nonfluent aphasia were randomly allocated to receive real or sham rTMS. Each patient received 1000 rTMS pulses (1 Hz at 110% of resting motor threshold [rMT] over the right unaffected Broca’s area and 1000 pulses (20 Hz at 80% rMT) over the left affected Broca’s area for 10 consecutive days followed by speech/language training. The language section of the Hemispheric Stroke Scale (HSS), the Stroke Aphasic Depression Questionnaire–Hospital Version (SADQ-H), and the National Institutes of Health Stroke Scale (NIHSS) were measured before, immediately after the 10 sessions, and 1 and 2 months after the last session. Results. At baseline, there were no significant differences between groups in demographic and clinical rating scales. However, there was a significantly greater improvement in the HSS language score as well as in the SADQ-H after real rTMS compared with sham rTMS, which remained significant 2 months after the end of the treatment sessions. Conclusion. This is the first clinical study of dual-hemisphere rTMS in poststroke aphasia. Combining dual-hemisphere rTMS with language training might be a feasible treatment for nonfluent aphasia; further multicenter studies are needed to confirm this result.

Epidemiological Study and Clinical Profile of Parkinson’s Disease in the Assiut Governorate, Egypt: A Community-Based Study

Research Abstract
Background: Few comprehensive epidemiological studies of the prevalence of Parkinson’s disease (PD) have been undertaken in Arab countries, and none has been carried out in Egypt. A community-based survey was conducted in the Assiut Governorate to estimate the prevalence and clinical profile of PD. Methods: A community-based study was carried out, with random sampling of 7 districts, involving 6,498 inhabitants. Out of this sample, 578 subjects dropped out, leaving 3,066 males (51.8%) and 2,854 females (48.2%). There were 3,660 urban residents (61.8%) and 2,260 (38.2%) from the rural community. Patients were evaluated using a screening questionnaire, the Unified Parkinson Disease Rating Scale and the Non-Motor Symptoms Scale for PD. Results: Thirty-nine subjects were found to have parkinsonism, giving a crude prevalence rate of 659/100,000 inhabitants. Of these subjects, 33 were diagnosed with PD (21 males), with a mean age of 66.9 8 8.4 years, a crude prevalence rate of 557/100,000 and an age-specific prevalence rate ( 6 50 years old) of 2,748/100,000. There were more males than females (3,395 vs. 1,989/100,000), but the difference was not signifi-cant. The highest age-specific prevalence rate was recorded among subjects 70–79 years old (7,263/100,000). There was a significantly higher prevalence among rural than urban inhabitants (973 vs. 301/100,000) and among illiterate than literate persons (1,103 vs. 280/100,000). The clinical profile of our patients was similar to that of other populations but was characterized by a high prevalence of mood/cognition dysfunction and gastrointestinal symptoms; there were few reported perceptual problems. Conclusion: The overall prevalence of PD was high, especially in older adults.
