Question 1

Motor symptoms

Accepted Answer

Motor symptoms are symptoms affecting movement and balance. In Parkinson’s disease, they are common, and generally the most visible symptoms. People with Parkinson’s disease can experience motor symptoms such as stiffness, slowness of movement, tremor at rest or during gait. Resting tremor usually affects the upper limbs, being commonly asymmetric, but it can be present in the lower limbs as well, or the chin.

Question 2

Prodromal stage/prodromal period

Accepted Answer

In medicine, the term prodromal refers to the latent period between the appearance of early symptoms of an illness, and when it develops to the point of being more visible. The prodromal stage in Parkinson’s disease is the stage after the disease is present in the brain, but before motor symptoms are prevalent, meaning it is not necessarily diagnosable yet.

During this stage, subtle signs can develop that may not seem connected to Parkinson's at the time. It is important to note that symptoms during the prodromal stage do not always lead to Parkinson's disease, only a small percentage of people with these symptoms go on to develop Parkinson's.
