Final answer:
In a suspected case of Parkinson's disease, the expected symptoms to observe would be muscle tremor, particularly at rest, muscle rigidity, and slowness of movement (bradykinesia). As the disease advances, postural instability, difficulty walking, and psychological symptoms such as depression and dementia become more common.
Step-by-step explanation:
Parkinson's disease is a neurodegenerative disorder that leads to the progressive decline of motor and cognitive functions. In clients with a suspected diagnosis of Parkinson's disease, one would expect to observe several characteristic symptoms that include:
- Muscle tremor (commonly seen in a limb at rest and disappearing during voluntary movement or sleep),
- Muscle rigidity (which can notably affect the facial muscles leading to a masked facial expression),
- Slowness of movement (bradykinesia),
As the disease progresses, symptoms such as postural instability, difficulty walking, and dementia become more prevalent. Furthermore, psychological symptoms like depression and emotional problems are also common, affecting the quality of life of individuals with Parkinson's disease.
