Second Pinky Exercise To Reduce Dementia Is Going Viral — And Neurologists Have Thoughts

Key Points:

• The viral TikTok trend "pinky time" involves a simple finger exercise claimed to protect against Alzheimer's and improve brain plasticity by moving the pinky fingers for several seconds daily.
• Neurologists acknowledge that finger exercises can stimulate the brain and support neuroplasticity, but the specific "pinky time" movements lack scientific study and should not be considered a proven medical intervention.
• Brain benefits from finger exercises come from the complexity and novelty of coordinated movements that engage multiple brain networks, rather than the specific finger used or the timing of the exercise.
• Experts recommend engaging in hobbies that involve fine motor skills and rhythmic finger movements, such as playing musical instruments, tai chi, or crafting, as part of a lifestyle that promotes cognitive health.
• The claim that finger exercises must be performed at a specific time daily is unfounded; benefits can be gained by moving fingers whenever convenient.
