6 overlapping signs of Parkinson’s and TD that are easy to miss
Parkinson’s disease and tardive dyskinesia (TD) are two distinct neurological conditions that can exhibit overlapping symptoms, which can sometimes make it challenging to differentiate between them, especially when assessing individuals who have been suffering from the disease for a long time. It is not necessary for all known and common symptoms of the condition to overlap. However, there are glaring differences in terms of severity and how these problems can develop, affecting individuals. Tremors One of the most recognizable symptoms of Parkinson’s disease and Tardive dyskinesia is early tremors. Resting tremors are a typical feature of Parkinson’s disease, affecting a majority of the patients. These tremors generally develop in the arms and legs. Second, if there is any activity, the tremors decrease or stop during purposeful movement. This means Parkinson’s tremors are typically rhythmic and worsen when the person is sitting or lying down. The tremors may initially be subtle, like a slight shaking of the hand, but can become more pronounced over time. Tardive dyskinesia also involves tremors that may more or less resemble the resting tremors observed in PD. However, TD tremors can be more irregular and jerkier, more prolonged, and visibly evident when compared to the subtle movements of Parkinson’s.
