Summary
A quick cognitive screening method asks older adults to name as many four-legged animals as possible within one minute, with 12 or more indicating normal function. The test is part of the BHT-7 Brain Fitness Assessment, which studied 1,090 participants aged 50 and above. Health experts emphasize that daily habits—including physical activity, mental stimulation, social engagement, medical management, and proper nutrition—can help prevent or delay dementia.
