A patient with Parkinson's Disease (PD) is being cared for on your unit. The nurse would be correct in identifying what neurotransmitter as being decreased in this disease?

Question

BlackTom AI · Accepted Answer

In this clinical scenario, we must identify the neurotransmitter most characteristically decreased in Parkinson's disease.
Option: Noradrenaline. While norepinephrine systems can be affected in various neurodegenerative processes and there may be some autonomic involvement, the hallmark neurotransmitter reduction that defines PD is not primarily noradrenaline. This choice does not capture the core pathophysiology of PD.
Option: Dopamine. This is the key neurotransmitter that degenerates in the nigrostriatal pathway (substantia nigra to striatum), leading to the classic motor symptoms of Parkinson's disease such as bradykinesia, rigidity, resting tremor, and postural instability. The dopamine loss is the defining feature that guides most treatments (e.g., L-dopa replacement).
Option: Serotonin. Serotonergic changes can occur in PD and may contribute to non-motor symptoms, but serotonin is not the primary neurotransmitter depleted in the disease. Relying on serotonin deficiency would miss the central pathophysiology.
Option: Acetylcholine. In PD, acetylcholine activity in the striatum can become relatively overactive due to dopamine depletion, rather than being decreased. Thus, this option is inaccurate as the defining decreased neurotransmitter. Treatments often address the imbalance between dopamine and acetylcholine rather than simply reducing acetylcholine levels.
