Plain language summary
Gluten related disorders (GRDs) is an umbrella term for diseases triggered by gluten, including coeliac disease and gluten sensitivity. People with GRDs may experience a wide range of symptoms including digestive and nervous system issues. Movement Disorders (MDs) refers to a group of nervous system conditions that cause abnormal movements, which may be voluntary or involuntary. This literature review looked at the current research on GRDs and MDs such as epilepsy, Parkinson’s disease, restless leg syndrome and tremors. 48 papers were used for the review. Most papers looked at MDs in those diagnosed with coeliac disease, rather than other GRDs. The authors found many examples where the symptoms of MDs, including chorea, restless leg syndrome, stiff person syndrome and tics, improved on a gluten free diet. The authors concluded that gluten-related MDs may be more common than previously thought, and that following a gluten free diet can be beneficial in many cases. They recommended that gluten sensitivity and coeliac disease should be considered in patients with MDs of unknown cause.
Abstract
Gluten related disorders (GRD) represent a wide spectrum of clinical manifestations that are triggered by the ingestion of gluten. Coeliac disease (CD) or gluten sensitive enteropathy is the most widely recognised, but extra-intestinal manifestations have also been increasingly identified and reported. Such manifestations may exist in the absence of enteropathy. Gluten sensitivity (GS) is another term that has been used to include all GRD, including those where there is serological positivity for GS related antibodies in the absence of an enteropathy. Gluten ataxia (GA) is the commonest extraintestinal neurological manifestation and it has been the subject of many publications. Other movement disorders (MDs) have also been reported in the context of GS. The aim of this review was to assess the current available medical literature concerning MDs and GS with and without enteropathy. A systematic search was performed while using PubMed database. A total of 48 articles met the inclusion criteria and were included in the present review. This review highlights that the phenomenology of gluten related MDs is broader than GA and demonstrates that gluten-free diet (GFD) is beneficial in a great percentage of such cases.
