Question: Pathological changes in a typical Parkinson disease patient includes:

Option 1: the death of dopaminergic neurons. This aligns with the core neuropathology of classic Parkinson disease, where loss of dopamine-producing neurons in the substantia nigra pars compacta leads to the hallmark motor symptoms. The downstream consequence is reduced dopaminergic signaling in the striatum, contributing to bradykinesia, rigidity, and tremor.

Option 2: a mutation in the α-synuclein gene. While α-synuclein aggregation forms Lewy bodies and is involved in PD pathology, not all cases are due to a genetic α-synuclein mutation; many are sporadic. Therefore, this describes a possible mechanism in some familial cases but is not the typical or universal pathological change seen in the majority of patients.

Option 3: a meningocele in the spinal cord. A meningocele is a neural tube defect involving protrusion of the meninges; it is unrelated to Parkinson disease pathology and would not be expected as a feature of PD.

Option 4: anencephaly. Anencephaly is a severe congenital brain malformation incompatible with life and bears no relationship to the typical neurodegenerative process of Parkinson disease, making it an incorrect choice in this context.

In evaluating the wording, the most representative and widely recognized pathological change in classic PD is the progressive loss of dopaminergic neurons in the substantia nigra, with Lewy body formation contributing to disease mechanisms. The other options describe processes or conditions not characteristic of the typical PD pathology.
