jormad,
Sorry you have to be here.
Read Dr. Boeve's "Continuum" paper on proper treatment for someone with LBD, and give it to the MD as well.
Contact the San Diego chapter of the Alzheimer's Association to learn if there's a support group for family members to attend.
And, contact the Caregiver Resource Center in your local area. (See cacrc.org for a list of these California centers.) If you are in San Diego county, that would be the Southern CRC; find them online at:

Find out what services they make available to caregivers in your area. The local CRC in the SF Bay Area offers terrific training classes for caregivers on dealing with dementia-related behavior.
Good luck,
Robin
