    Celiac.com 01/15/2018 - Cerebellar ataxia with sensory ganglionopathy is a disabling combination of neurological dysfunction that usually occurs as part of certain hereditary ataxias. However, some patients present this combination with no apparent genetic cause.

    A team of researchers recently set out to if autoimmunity might have a role to play in SG. The research team included Panagiotis Zis, Ptolemaios Georgios Sarrigiannis, Dasappaiah Ganesh Rao, Nigel Hoggard, David Surendran Sanders, and Marios Hadjivassiliou. They are variously affiliated with the Academic Department of Neurosciences, Sheffield Teaching Hospitals NHS Foundation Trust, Sheffield, UK; the University of Sheffield, Sheffield, UK; the Department of Neuroradiology, Sheffield Teaching Hospitals NHS Foundaiton Trust, Sheffield, UK; the University of Sheffield, Sheffield, UK; and the Academic Unit of Gastroenterology, Sheffield Teaching Hospitals NHS Foundation Trust, Sheffield, UK.

    The team reviewed records of all patients that have been referred to the Sheffield Ataxia Centre who had neurophysiological and imaging data suggestive of SG and cerebellar ataxia respectively. We excluded patients with Friedreich's ataxia, a common cause of this combination. All patients were screened for genetic causes and underwent extensive investigations.

    They found 40 patients with combined cerebellar ataxia and sensory ganglionopathy. The majority of patients were initially diagnosed with cerebellar dysfunction, and about one-third were initially diagnosed with sensory ganglionopathy.

    For that one-third, the two diagnoses were made together. The average time between the two diagnoses was 6.5 ± 8.9 years, ranging from 0 up to 44 years. The most common initial symptom was unsteadiness, in 77.5% of patients, followed by patchy sensory loss in 17.5%, and peripheral neuropathic pain in 5%.

    Nineteen patients had gluten sensitivity, of whom 3 patients had biopsy proven celiac disease. Other abnormal immunological tests were present in another 15 patients. Six patients had malignancy, which was diagnosed within 5 years of the neurological symptoms. Only 3 patients were classified as having a truly idiopathic combination of cerebellar ataxia with sensory ganglionopathy.

    This study shows that immune pathogenesis plays a significant role in patients with the unusual combination of cerebellar ataxia and sensory ganglionopathy.

    Celiac.com 06/01/2015 - Earlier research on celiac disease and neuropathy has been hampered by the use of inpatient data, low study power, and lack of information on neuropathic characteristics.
    A team of researchers recently set out to accurately assess both relative and absolute risk of developing neuropathy in a nationwide population-based sample of patients with biopsy-verified celiac disease. The research team included Sujata P. Thawani, MD, MPH; Thomas H. Brannagan III, MD; Benjamin Lebwohl, MD, MS; Peter H. R. Green, MD; and Jonas F. Ludvigsson, MD, PhD.

    Celiac.com 08/10/2017 - Gluten ataxia is defined as sporadic ataxia with positive antigliadin antibodies without an alternative cause. Gluten ataxia patients often receive MRS at baseline and again after a period on a gluten-free diet.
    A research team recently set out to evaluate the effect of gluten free diet on magnetic resonance spectroscopy (MRS) of the cerebellum in patients with gluten ataxia.
    The research team included M Hadjivassiliou, RA Grünewald, DS Sanders, P Shanmugarajah, N Hoggard. They are with the Academic Departments of Neurosciences (M.H., R.A.G., P.S.), Gastroenterology (D.S.S.), and Neuroradiology (N.H.), Sheffield Teaching ...

    Celiac.com 11/27/2017 - For centuries, physicians have used cannabis to treat numerous disorders. Modern research shows that various cannabis compounds can alleviate symptoms from numerous conditions, including neurological disorders, cancer, rheumatism, epilepsy, sexual disorders, pain, among others.
    Many people with celiac disease suffer from neuropathy, which causes nerve pain, among other symptoms. Neuropathy can be difficult to treat. Nerve pain is a debilitating symptom that can significantly impair a patient's quality of life. Could a new cannabis patch change that?
    Some researchers think so. One California-based company, Cannabis Science...
