Early Sign of Alzheimer’s Disease Visible Before CT Scan – Top Health
A new study conducted by researchers at the School of Medicine at the University of Washington in the United States has found that stopping driving in older adults may be an early sign of Alzheimer’s disease. The study, published in the journal Neurology, followed 283 participants with an average age of 72 who drove at least once a week. They underwent cognitive tests at the beginning of the study and annually for an average of 5.6 years. They also had brain scans and cerebrospinal fluid samples taken at the beginning of the study, and then every two or three years.
During the study, 24 people stopped driving, 15 passed away, and 46 developed cognitive impairments. Overall, about one-third of the group met the criteria for preclinical Alzheimer’s disease based on disease biomarker levels. Interestingly, the study found that women were four times more likely to stop driving than male participants. Those who met the criteria for cognitive impairment were 3.5 times more likely to stop driving than those without cognitive issues. Participants with lower cognitive test scores were 30% more likely to stop driving than those with higher scores.
“This study confirms the recommendations of the 2010 American Academy of Neurology guideline, which states that progression to mild cognitive impairment increases the risks associated with driving. This is the time to advise people to stop driving,” said expert Richard M. Dubinsky from the University of Kansas. However, the study had some limitations, as researchers did not have information on other health conditions, vision or hearing decline, or the use of medications such as antidepressants and sedatives, all of which are associated with risky driving behaviors.
Impact of Cognitive Impairment on Driving Behavior
The study’s findings shed light on how cognitive impairment can affect driving behavior in older adults. Cognitive decline can significantly impact a person’s ability to safely operate a vehicle, posing risks to both the individual and others on the road. Identifying early signs of cognitive impairment, such as stopping driving, can help healthcare professionals intervene and provide appropriate guidance to ensure road safety.
Recommendations for Older Drivers and Healthcare Providers
Based on the study results, it is crucial for older adults and healthcare providers to recognize the potential implications of cognitive impairment on driving abilities. Regular cognitive assessments and discussions about driving behavior should be part of routine healthcare screenings for older individuals. Healthcare professionals play a key role in identifying signs of cognitive decline and providing support and resources to help older adults navigate potential challenges related to driving cessation. By addressing these issues proactively, individuals can maintain their safety and that of others on the road.
In conclusion, the study highlights the importance of monitoring driving behavior as a potential early indicator of Alzheimer’s disease in older adults. Early intervention and support can help mitigate risks associated with cognitive impairment and promote road safety for all individuals.
