Maximum Tongue Pressure is Associated with Swallowing Dysfunction in ALS Patients

AbstractMaximum tongue pressure (MTP) measurement is a convenient, less invasive assessment that has been developed to quantify tongue strength; however, it is unclear whether MTP is useful for the detection of swallowing disorders in amyotrophic lateral sclerosis (ALS) patients. The purpose of this study was to clarify the relationship between MTP and the characteristics of swallowing disorders on videofluorography and to determine the usefulness of tongue pressure measurement for the assessment of swallowing function in ALS patients. Twenty-five ALS patients were evaluated according to the ALS functional rating scale-revised (ALSFRS-R), and their ability to swallow yogurt was observed via videofluorography. MTP was measured using a device (TPM-01, JMS, Hiroshima) equipped with a balloon probe. Then, the relationships between the ALSFRS-R score, swallowing function, and MTP were analyzed. MTP was significantly lower in the subjects with reduced tongue function (p = 0.002) or with pharyngeal residue (p = 0.006) than in the subjects with normal characteristics. Bolus formation and oral transit time and pharyngeal transit time were significantly prolonged among those with reduced MTP. MTP at a cut-off value of 21.0 kPa was associated with a full score on the bulbar-related items of the ALSFRS-R. MTP may serve as a new diagnostic tool for the early detection of swallowing dysfunction in ALS patients, because of its good relationship with their swallowing...

(University of California - Riverside) Maurizio Pellecchia at the University of California, Riverside has received two grants to continue his research aimed at finding therapeutics for cancer, amyotrophic lateral sclerosis (ALS), and other neurodegenerative diseases. The first grant from the US-Egypt Science and Technology Joint Fund of the National Academy of Sciences, Engineering, and Medicine totals $190,000 for two years. The second is a nearly $2.3 million, five-year grant from the National Institute of Neurological Disorders and Stroke.

The aetiology of ALS remains an enigma which hinders the design of an effective treatment to prevent, postpone, or reverse the pathophysiological changes occurring during the aggressive progression of this disease. During the last decade, basic research within the innate immune sy...

Schwarzschild Dominant mutations in an antioxidant enzyme superoxide dismutase-1 (SOD1) cause amyotrophic lateral sclerosis (ALS), an adult-onset neurodegenerative disease characterized by loss of motor neurons. Oxidative stress has also been linked to many of the neurodegenerative diseases and is likely a central mechanism of motor neuron death in ALS. Astrocytes derived from mutant SOD1 G93A mouse m...

Abstract Cannabinoid receptor CB2 (CB2R) is upregulated on activated microglia and astrocytes in the brain under inflammatory conditions and plays important roles in many neurological diseases, such as Alzheimer's disease, amyotrophic lateral sclerosis, and ischemic stroke. The advent of positron emission tomography (PET) using CB2R radiotracers has enabled the visualization of CB2R distribution in vivo in animal models of central nervous system inflammation, however translation to humans has been less successful. Several novel CB2R radiotracers have been developed and evaluated to quantify microglial activation. ...

The S-oxidation of S-carboxymethyl-L-cysteine has been reported previously to be a biomarker of disease susceptibility in Parkinson ’s disease and Amyotrophic lateral sclerosis. In this investigation, the original observations have been confirmed with the incidence of the poor metaboliser phenotype (no urinary recovery of S-oxide metabolites) being found to be 3.9% within healthy control population. However, 38.3% of the Parki nson’s disease subjects and 39.0% of the Amyotrophic lateral sclerosis group were phenotyped as poor metabolisers.
