Weather extremes, like high temperatures, have a significant impact on senior citizens, but for people living with Alzheimer’s disease or another dementia, the danger can present a hazardous or fatal situation.

The Alzheimer’s Association recommends taking the following steps in cases of extreme heat:

Make a plan

Family and friends should make plans to check in on the person living with Alzheimer’s disease or other dementia throughout the heat wave. If air conditioning is not available at their residence, they should find a way to keep the individual and their caregiver cool, at a private residence or public place.

Pay attention at night

Just because the sun is down does not mean the heat has gone away. Low temperatures can still exceed 75 degrees with little fluctuation in humidity levels, making for difficult sleeping conditions, heightening anxiety and agitation, and exacerbating sleep issues. Keep the person cool by using fans and keeping the air conditioning on, if available.

Prepare for behavioral challenges

Studies have shown that heat can increase agitation in people. Try to remove behavioral triggers by addressing the individual’s physical needs related to the heat, then tending to their emotional needs. 

Stay hydrated

Dehydration may be difficult to notice in a person living with Alzheimer’s disease or another dementia, as signs like increased fatigue, dry mouth, headache, and/or decreased urinary output, may be difficult to detect. Increased water intake is essential to maintaining good hydration and health during a heat wave.

People taking diuretics, sedatives, or certain heart medication may not sweat as much as others, but this does not mean that they are not hot.

Stay indoors and out of the sun

Heat stroke and heat exhaustion are common in senior citizens and symptoms may be difficult to detect in individuals living with a form of dementia. Keep cool by using air conditioning in your home or at a public place, such as a senior center or shopping mall.

If you must go outside, be sure to wear a hat or other head covering and use sunscreen with a SPF rating of at least 30.

Stay informed

Keep an eye on local weather forecasts on television or online, as temperature is not the only concern. Humdity, air pollution indicies and other environment concerns can cause breathing difficulties.

According to the Centers for Disease Control and Prevention, heat stroke occurs when the body is overwhelmed by heat and unable to control its temperature, causing it to increase above 103 degrees Fahrenheit. Symptoms of heat stroke include: strong rapid pulse, dry or flushed skin, dizziness, nausea, confusion or loss of consciousness. If untreated, heat stroke can lead to death. If you suspect heat stroke in any person, regardless of age or medical condition, call 911.

Heat exhaustion is a milder heat-related illness caused by exposure to high temperatures and humidity. Without treatment, it can lead to heat stroke. According to the CDC, symptoms include heavy sweating, cold, clammy skin, faintness, dizziness, weak and rapid pulse, muscle cramping, nausea and headache. It can be treated by moving to a cooler place, loosening one’s clothes, sponging the person with cool water or sipping cool water. The person should be monitored for symptoms of heat stroke and medical attention should be sought if symptoms last for more than one hour or if they are vomiting.
