Alzheimer’s caregivers have special challenges, interests, and needs.  Among them is connecting with others in similar straits to get the latest information from experts and those in the trenches. That’s why the Alzheimer’s Foundation of America recently launched Care Crossroads (www.carecrossroads.org), an interactive caregiver community Web site.  Besides videos and resources, it lets users connect with social workers and other experts via Skype and live chat, or brainstorm and commiserate with fellow caregivers via discussion boards and online support groups.  (Source: MetLife)
