You are playing with definitions. Let me rephrase it more precisely: By damaging the brain, you can damage mental states. Also by damaging the brain you can make person blind, deaf, not-feel any pain, etc.
It is also not just matter of causation, but of dependence
. Even if the brain is not the sole cause for mind, or consciousness - if it is necessary cause, then even if other causes are met, if this necessary cause is missing - then consciousness or mind will not occur.

1) How can radio convert sound carrying Beethoven's Symphony No. 5 into coherent music such as "Sweet Dreams" by Marylin Manson.
2) Even if you could change any signal into any coherent music, the final outcome is still with the radio. If brain is responsible for interpretation of "signal" as loving kindness or hatred, then the brain is still important and necessary cause for the final outcome.
3) Without the radio, what music can the signal produce? It can't. Same is with brain.
Radio wave is produced by physical causes, and quickly ceases. What produces consciousness (if not the brain
) and how can we study it?
4) If consciousness is immaterial and has no place, then how does it interact with physical objects that have place? Why is it when I walk downstairs or upstairs, the consciousness changes location? What keeps it glued to this body and location of this body?
