Parkinson's disease has been diagnosed in a client exhibiting tremors. Which of the following is lacking in this disorder? A. Celestone B. Dopamine C. Serotonin D. Anti-diuretic hormone

Short Answer

Expert verified
A) Celestone B) Dopamine C) Serotonin D) Anti-diuretic hormone Answer: B) Dopamine

Step by step solution

01

Understand Parkinson's disease

Parkinson's disease is a progressive neurological disorder that affects movement. It occurs when some nerve cells in the brain start to break down and die. These nerve cells are known as neurons, and they produce a chemical messenger called dopamine. When dopamine levels decrease, it causes symptoms like tremors and muscle stiffness typically seen in Parkinson's disease.
02

Analyze Option A - Celestone

Celestone (betamethasone) is a corticosteroid medication that is used to treat various conditions such as allergies, skin conditions, arthritis, and more. It is not directly related to Parkinson's disease, nor does it address the neurological issues or chemical imbalances associated with Parkinson's.
03

Analyze Option B - Dopamine

Dopamine is a neurotransmitter that plays a key role in controlling movement, emotional responses, and the brain's reward and pleasure centers. Reduced dopamine levels result from the death of dopamine-producing neurons in Parkinson's disease. This leads to impairments in motor functions, including tremors.
04

Analyze Option C - Serotonin

Serotonin is a neurotransmitter that helps regulate mood, sleep, appetite, and other functions. While low levels of serotonin can contribute to other mental health issues like depression, serotonin imbalances are not a primary contributing factor to Parkinson's disease.
05

Analyze Option D - Anti-diuretic hormone

Anti-diuretic hormone (ADH) is a hormone that regulates water balance in the body by controlling the amount of water that kidneys reabsorb. Its primary functions are unrelated to Parkinson's disease, and its levels do not have a significant impact on the development or progression of the disease.
06

Select the correct answer

Based on our analysis of each option, we can conclude that Parkinson's disease is primarily caused by a lack of dopamine (Option B). Dopamine levels decrease as dopamine-producing neurons die, leading to the characteristic symptoms of tremors and other movement impairments.
