What severe outcomes, besides headaches, can result from eosinophilic meningitis caused by snail parasites?
Answer
Permanent neurological damage or death
Eosinophilic meningitis, triggered by the migration of *Angiostrongylus cantonensis* larvae into the central nervous system after consuming infected wild snails, is a severe neurological condition. The symptoms associated with the acute phase include debilitating severe headaches and pronounced neck stiffness. However, the prognosis carries significantly graver risks. If the parasitic invasion and resulting inflammation are substantial, the condition has the potential to cause irreversible damage to the neurological structures, which can ultimately lead to permanent neurological impairment or even be fatal to the infected individual.
