The Aging and Disability Resource Unit (ADRU) takes calls regarding abuse, neglect, self-neglect and/or financial exploitation of a vulnerable adult (age 18 or older). The main Adult Protective Services (APS) referral line is 1.800.91. PREVENT; or, 1. 800.917.7383. A vulnerable adult is unable to make decisions on their own behalf due to a mental and/or medical or health condition, that renders someone physically unable to care for themselves. For situations on weekends/after hours and overnight (between 5:00 PM and 8:30 AM) on weekdays, and holidays, call Montgomery County Crisis Center at 240-777-4000. The Crisis Center will receive the call and then contact the APS covering worker.
