It typically causes symptoms such as hearing loss, tinnitus, dizziness, and balance problems. Sensory aphasia refers to difficulty in understanding and expressing language, while motor aphasia refers to difficulty in speaking or articulating words. Although acoustic neuroma can affect the auditory system and cause auditory defects and changes in audimetry, it does not typically cause motor aphasia.
