As one who believes in souls and afterlife; I would suggest considering the analogy of a musician and their instrument. If a musician's instrument is severely damaged, they may no longer be able to produce music through it. However, the musician's skill, knowledge of music, and ability to compose ought remain intact. Similarly, the soul's inherent faculties are not destroyed by brain damage; rather, the damaged brain can no longer adequately manifest these faculties. The body, being material, is subject to change, decay, and illness. When the brain is damaged, as in the case of meningitis leading to ABI, it impairs the body's ability to serve as an effective instrument for the soul.
