Parkinson's disease
Verified step by step guidance1
Understand the role of dopamine in the brain: Dopamine is a neurotransmitter that plays a key role in sending signals in the brain and is involved in movement, motivation, and reward.
Identify the neurons affected in Parkinson's disease: Parkinson's disease is characterized by the death of neurons in the substantia nigra, a region of the brain that produces dopamine.
Recognize the symptoms associated with dopamine deficiency: The loss of dopamine-producing neurons leads to symptoms such as tremors, stiffness, and difficulty with balance and coordination.
Differentiate Parkinson's disease from other neurological disorders: While schizophrenia, Alzheimer's disease, and major depressive disorder involve different neurotransmitter systems and brain regions, Parkinson's disease specifically involves the loss of dopamine-producing neurons.
Conclude that the correct answer is Parkinson's disease: Based on the understanding of dopamine's role and the specific neuronal loss in Parkinson's disease, it is clear that this condition is caused by the death of neurons that release dopamine.
