According to the CDC, 6.2 million people in the US are living with Alzheimer’s disease, the most common form of dementia. “Diagnosing dementia and its many types can be challenging for physicians,” says Glen Stevens, DO, PhD. “It is estimated that 5% of individuals over the age of 65 have severe dementia, and 10 to 15% are at least mildly impaired. As the size of the elderly population expands, the number of individuals with dementia will inevitably increase. Early and accurate diagnosis is the major objective in dementia evaluation. ” Here are five warning signs of dementia you should never ignore.

Struggling to pick up on sarcasm or losing the ability to understand a joke could be an early symptom of dementia. “Early signs of dementia include changes to language, behaviors and responses to social cues,” says Hannah Churchill, research communications manager at Alzheimer’s Society.
“If you find your sense of humor has changed significantly, it might be worth getting some medical advice,” says Katie Puckering, information services manager for Alzheimer’s Research UK.
Changes in mood could be a sign of dementia. “Scientists have long known that depression and dementia go hand in hand,” says Dr Cornelia Cremens, assistant professor of psychiatry at Harvard Medical School. “If somebody appears to have the beginnings of dementia and they are depressed, it’s very important to treat their depression, and to treat it as aggressively as possible.”

There is growing evidence that dementia can be seen from the way a person walks, and could even be used for early diagnosis: “They walked slower with shorter steps, were more variable and asymmetric, and spent longer with both feet on the ground compared to control subjects, ” says Ríona McArdle, Post-Doctoral Researcher, Brain and Movement Group, Newcastle University. “This shows that people with dementia have significant walking problems, and that we need to look at this in people at risk of developing dementia to see if it can predict the onset of the condition.”
