Chiari I malformation is accompanied by a variety of symptoms and signs suggesting brain stem, cerebellar, or cervical spinal cord lesions. The most common symptoms include headache, neck pain, sensory loss, and ataxia. Dysphagia occurs in 5-15% of the patients and it may be the only presenting symptom. Progressive dysphagia caused by Chiari I malformation, mimicking amyotrophic lateral sclerosis, has been reported in the "Journal of Neurology, Neurosurgery and Psychiatry" in 1996 and 2002. Dysphonia may occur rarely, but it has not been described as an early symptom. Pain and stiffness in the posterior neck is a common feature, but severe neck extensor weakness leading to dropped head syndrome has not so far been reported in Chiari I malformation.

    In amyotrophic lateral sclerosis (ALS) patients, dysphagia eventually occurs independent of time of onset. We studied dysphagia conditions in the early stage of ALS, principally at the oral phase. Videofluoroscopic and manometric studies were conducted on 11 patients (5 males and 6 females, age...

    Dysphagia is one of the most critical problems in patients with progressive neuromuscular diseases. However, clinically useful and practical scales to evaluate dysphagia are limited. Therefore, the aim of this study was to develop such a scale. An 8-stage Neuromuscular Disease Swallowing Status...

    A method is presented for analyzing phonatory instabilities that occur as modulations of fundamental frequency (f[sub0] ) and sound pressure level (SPL) on the order of 0.2 to 20 cycles per second. Such long-term phonatory instabilities, including but not limited to traditional notions of...
