Question

Dottie has a disease characterized by motor tremors, loss of balance, poor coordination, rigidity, and difficulty moving. Dottie has:

1) Parkinson's disease
2) Alzheimer's disease
3) Multiple sclerosis
4) Cerebral palsy

Answer 1

Dottie's constellation of symptoms corresponds to Parkinson's disease, which is a result of the loss of dopamine-producing neurons in the substantia nigra part of the brain.

Step-by-step explanation:

Dottie's symptoms of motor tremors, loss of balance, poor coordination, rigidity, and difficulty moving are indicative of Parkinson's disease, a neurodegenerative disease characterized by the degeneration of neurons that release dopamine. These neurons are located in the substantia nigra, a critical area of the brain for regulating movement. The loss of these neurons leads to distinct symptoms like a slow hunched shuffling walk, tremor, slowed movement, speech changes, and rigid muscles. Parkinson's disease may also have non-motor symptoms such as psychological issues, including dementia or emotional problems in its advanced stages.
