Ataxia
Nystagmus
Dysphagia
Aphasia
Hemiparesis
Correct Answer : A,B,C
Choice A reason:
This statement is true. Ataxia is a lack of coordination of voluntary movements that can affect the gait, balance, speech, or eye movements. It is caused by damage to the cerebellum, which is responsible for coordinating muscle activity and maintaining posture and equilibrium.
Choice B reason:
This statement is true. Nystagmus is a rapid involuntary movement of the eyes that can be horizontal, vertical, or rotary. It is caused by damage to the cerebellum or the vestibular system, which regulates the sense of balance and spatial orientation.
Choice C reason:
This statement is true. Dysphagia is difficulty swallowing that can affect the oral, pharyngeal, or esophageal stages of swallowing. It is caused by damage to the cerebellum or the brainstem, which control the muscles involved in swallowing.
Choice D reason:
This statement is false. Aphasia is a loss or impairment of language function that can affect the expression, comprehension, reading, or writing of speech. It is caused by damage to the cerebral cortex, especially the left hemisphere, which is responsible for language processing.
Choice E reason:
This statement is false. Hemiparesis is weakness or paralysis of one side of the body that can affect the face, arm, or leg. It is caused by damage to the cerebral cortex or the corticospinal tract, which control voluntary movement.

Choice C reason:
This statement is not an adverse effect of chemotherapy, but of the brain tumor itself. Brain tumors can cause increased intracranial pressure by applying pressure to surrounding brain tissue and impairing cerebral blood flow and cerebrospinal fluid drainage.
Choice D reason:

Choice C reason:
This statement is correct, as explained above.
Choice D reason:
This statement is not correct. Acoustic neuromas are benign brain tumors that arise from the acoustic cranial nerve and may cause hearing loss or ringing in the ears, vertigo, facial drooping, or difficulty swallowing, but they do not typically affect vision or reading ability.
