Celiac disease may present as neurological and psychiatric problems
Yes, latest research seems to support the link between celiac disease and many neurological or psychiatric disorders. Though we must caution that such symptoms are not present in all the patients, neither does it mean that diet rich in gluten is bad for the brain. The interrelation between neuropsychiatric disturbances and celiac disease are poorly understood, very little is known about the mechanism involved in such manifestations of the disease. But many people in celiac disease are known to present with ataxia, encephalopathies, and peripheral neuropathies. While a small number of them may also present with serious psychiatric issues like anxiety, depression, various mood disorders, attention deficit hyperactivity disorder, and in extreme cases even with schizophrenia (4,5).
