What is a likely consequence of insufficient dopamine levels in Parkinson's disease?

1. Improved motor movements

2. Impaired balance and coordination

3. Increased emotional well-being

4. Enhanced cognitive function

The correct answer is: Impaired balance and coordination

In Parkinson's disease, insufficient levels of dopamine directly impact the central nervous system, leading to various motor and non-motor symptoms. One of the significant consequences of reduced dopamine is impaired balance and coordination. Dopamine plays a crucial role in the brain's ability to control and smooth out movements, which are essential for maintaining balance and coordinating actions. Without adequate dopamine, patients often experience rigidity, bradykinesia (slowness of movement), and postural instability, all of which contribute to challenges in balancing and coordinating movements effectively. This understanding helps clarify the motor control deficits typically observed in individuals with Parkinson’s disease.
