Firstly, it may cause meningitis adhesions leading to hydrocephalus. Once hydrocephalus occurs, it may leave cognitive impairments as sequela, such as slow response, memory decline, and reduced executive functions. Secondly, tuberculous meningitis might also damage cranial nerves, resulting in symptoms such as diplopia, difficulty swallowing with choking on water, and dysarthria. If it affects the facial nerve, peripheral facial paralysis and other sequelae might occur. Thirdly, it could also lead to arteritis. The occurrence of arteritis can cause arterial occlusion, leading to the formation of cerebral infarction.
