My mother has been diagnosed with Alzheimers since 2001. We give her Seroquel at night so that she rests and is not so restless at night. In recent months I've started noticing more tremors in the hands and arms. Is this a normal occurance? Is there something else that we can give her that will decrease the tremors but still have the sedative effect at night? Should we even be giving her Seroquel?
