Answer :
Final answer:
Parkinson's disease is a neurodegenerative disorder caused by insufficient dopamine levels, leading to symptoms like tremors, rigidity, and difficulty with movement. Therefore, option b) Parkinson's disease is the correct answer.
Explanation:
The degenerative disorder as a result of insufficient amounts of dopamine is Parkinson's disease. This neurodegenerative condition impacts the substantia nigra, leading to a decreased production of dopamine. The basal nuclei become overly active, resulting in increased skeletal muscle tone, rigidity, and difficulty initiating voluntary movements. Symptoms include tremors, slowed movements, speech changes, balance and posture issues, and rigid muscles, often leading to a characteristic slow, hunched, shuffling walk. Parkinson's disease can also present psychological symptoms such as dementia or emotional issues.
