Though there hasn’t been definitely research showing a link between Alzheimer’s and an increased risk of drowning, an Internet search does yield stories of dementia patients who wandered away and drowned. Yet your loved one doesn’t have to wander away from home to face the hazards of being unsupervised around water. The Alzheimer’s Association says that “even the most basic appliance or household object can become dangers,” including kitchen or bathroom sinks. Because of forgetfulness, seniors may forget to turn off the water, resulting in a flooded bathroom. They may also slip getting into a tub or shower . To safeguard against these scenarios, reducing the water flow will prevent floods while allowing your loved one their independence of washing when they need to. Installing a non-slip mat in the shower or bathtub will prevent falls.
