Dementia Wandering Prevention in South Dakota: EMA, GPS Tracking, and Safety Plans

Approximately 60% of people with dementia will wander at least once. In South Dakota — where the nearest neighbor might be miles away and winter temperatures can drop well below zero — a wandering episode can become life-threatening within hours.

South Dakota Does Not Have a Silver Alert

Many families search for South Dakota's Silver Alert program. It does not exist. Instead, the state uses the Endangered Missing Advisory (EMA) system, coordinated by local law enforcement in partnership with the Division of Criminal Investigation's Missing Persons Clearinghouse and local broadcasters.

An EMA is activated when a vulnerable adult — including a person with Alzheimer's or dementia — goes missing under circumstances that indicate immediate danger of serious injury or death. The trigger factors include age, cognitive impairment, weather conditions, and the individual's physical health.

The practical difference for families: when your parent goes missing, call local law enforcement immediately and request an Endangered Missing Advisory, not a Silver Alert. Using the correct terminology ensures law enforcement initiates the state-wide broadcast protocol without confusion.

What to Have Ready Before a Wandering Crisis

When law enforcement arrives, they need this information immediately:

• A recent photograph — updated at least every six months, showing current appearance
• Physical description including height, weight, hair color, and any distinguishing features
• Medical history relevant to the search — dementia diagnosis, medications, mobility limitations
• Known wandering patterns — does your parent head toward a former workplace? A childhood home? The highway?
• Vehicle description if they still have access to a car (including license plate number)
• Clothing last worn — keep a mental note of what your parent is wearing each day

Preparing a laminated card with this information eliminates the scramble during a crisis. Give copies to local law enforcement proactively, before an incident occurs.

Layered Prevention Strategies

No single measure prevents wandering. Effective plans use multiple overlapping safeguards:

Home Modifications

• Door and window alarms that alert you when exits are opened — choose models with a chime loud enough to wake you at night
• Deadbolts placed high or low on exterior doors, out of the line of sight for someone with cognitive impairment
• Visual barriers on exit doors — a dark mat or curtain can deter a person with dementia from approaching a doorway
• Room labels and color-coded paths to reduce disorientation within the home
• Fencing around the property with secure gates — essential for rural properties where open land extends in every direction

GPS and Tracking Technology

• Dedicated GPS trackers designed for dementia patients — devices worn as watches, clipped to clothing, or hidden in shoe insoles. Look for models with geofencing alerts that notify you when your parent leaves a defined area.
• Cellular location sharing through a smartphone, if your parent still carries one — though many people with mid-stage dementia stop using phones
• AirTag or similar tracking devices placed on keys, wallets, or sewn into jacket linings — these rely on the Bluetooth network of nearby devices, which may be sparse in rural South Dakota
• Medical identification bracelets with your contact information and the parent's diagnosis — these help first responders identify and return your parent quickly

Community-Based Safety Net

• Alert your neighbors to your parent's diagnosis and provide your contact information. In rural areas, neighbors are often the first to spot someone walking along a road.
• Notify local law enforcement proactively — provide the information packet described above so they have it on file before an emergency
• Register with the local Alzheimer's Association chapter for MedicAlert + Safe Return, a nationwide identification and emergency response program

When Your Parent Goes Missing

Act within minutes, not hours:

1. Search the immediate area — check favorite rooms, the yard, outbuildings, and vehicles first
2. Call 911 and request activation of the Endangered Missing Advisory
3. Provide the pre-prepared information packet to responding officers
4. Check dangerous locations — bodies of water, busy roads, unlocked sheds, crawl spaces
5. Organize neighbors to search in expanding circles while law enforcement mobilizes

In South Dakota's climate, exposure is the primary threat. During winter months, a confused person wandering outdoors without proper clothing can develop hypothermia within 30 to 60 minutes.

Facility-Level Wandering Protection

When evaluating memory care facilities in South Dakota, the secured unit regulations require ground-floor placement with a fenced outdoor courtyard. But regulations set the floor, not the ceiling. Ask specifically about:

• Electronic exit-monitoring systems (wander-guard bracelets that trigger alarms at doors)
• Staff protocols when an alarm is triggered — how many seconds until response?
• Backup systems if primary monitoring fails
• Outdoor courtyard supervision schedules

The South Dakota Dementia Care Guide includes a wandering prevention checklist, an EMA information card template, and a facility safety assessment for evaluating memory care units.
