-Constipation. PD and the drugs used for its treatment contribute to constipation. Severe constipation can lead to a medical emergency. If constipation continues to be a problem, it is important to seek medical help.
Intellectually, people with PD usually remain normal. But because speech and everyday tasks take longer to execute, it may appear that they lack comprehension or understanding-when actually they know exactly what they want to do but are unable to process their thoughts or actions in a timely manner.
