Taken from the Conservator's Handbook published by the Superior Court of California...
"Treatment of Dementia - A conservator must obtain specific authorization from a judge to give exclusive consent for the treatment of dementia by the use of psychotropic drugs. These may be prescribed by a psychiatrist or by the conservatee's regular physician. It is important for the conservator to conduct a regular review of this type of treatment, with all the conservatee's doctors, to monitor carefully the effect that such drugs may have on the conservatee."
