In MTLE-associated hippocampal sclerosis, neuronal loss is accompanied by which process?

Explanation:
In mesial temporal lobe epilepsy with hippocampal sclerosis, the loss of neurons is accompanied by reactive gliosis. When neurons die in the hippocampus, astrocytes proliferate and become enlarged, forming a glial scar that fills and borders the damaged tissue. This gliosis reflects the brain’s response to injury and helps define the sclerosis seen histologically, often alongside other hippocampal changes like granule cell dispersion and mossy fiber sprouting. Other options describe processes not typical of this condition—calcification, Lewy bodies, or an astrocytoma-like pattern do not characterize MTLE-associated hippocampal sclerosis.
