Few mild-to-moderate Parkinson's disease patients suffer from malnutrition, yet almost one third are at risk

Many factors could lead to poor nutrition in Parkinson's disease (PD) patients, including motor difficulties with swallowing and chewing (dysphagia), cutting, and bringing food to the mouth. PD-related constipation and depression can also dampen a patient's appetite and change dietary habits. A new report says that some of these patients are therefore at risk of malnutrition.
