Most people reach for brain games, supplements, or complicated routines when thinking about brain health. But according to neurologist Dr Suraj Malhan, protecting cognitive function may be much simpler than people imagine. In a recent social media video, the doctor, who goes by the name Headacheguru online, demonstrated a series of quick hand and finger exercises that can be done in just two minutes a day. He explained that these movements are designed to stimulate multiple parts of the brain simultaneously and may help support long-term cognitive health.
Dr Malhan began by encouraging people to replace mindless scrolling habits with short coordination exercises. “Instead of doom scrolling, take a hand exercise break to prevent dementia,” he said in the video. According to him, the human brain dedicates a surprisingly large amount of space to controlling hand movements. He explained that the hands occupy more neurological space than almost any other body part. He added that even a single finger takes up more representation in the brain’s motor cortex than an entire thigh.
The neurologist explained that coordinated finger exercises activate several important brain regions at the same time. These include the motor cortex, sensory cortex, cerebellum, and frontal lobe, all areas associated with movement, coordination, focus, and higher cognitive function.
Science behind the finger exercise
Dr Malhan also referred to scientific findings supporting these exercises. He mentioned a 2023 meta-analysis involving more than 1,200 patients, which found that finger exercises helped improve cognitive scores, especially among individuals with mild cognitive impairment.
He pointed out that mild cognitive impairment is often considered the stage before dementia develops, making early intervention especially important. “The keyword is early,” he said, explaining that these exercises appear to work best before significant neurological connections are lost. One of the biggest advantages of these routines, according to him, is their simplicity. “You don’t need any equipment to do this,” he added, making the exercises easy to perform almost anywhere.
Finger exercises
Finger opposition sequencing
The first exercise demonstrated in the video was the beginner warm-up, also called finger opposition sequencing. In this movement, a person taps each finger to the thumb one by one, starting from the index finger and moving toward the pinky finger before reversing the sequence back again. While it may appear simple initially, the movement challenges coordination, timing, and neural communication between the brain and hands.
Thumb-pinky switch
Another exercise shown by Dr Malhan was the thumb-and-pinky switch. For this movement, one hand extends only the thumb while the other hand extends only the pinky finger. The person then rapidly switches both positions back and forth so that the thumb hand becomes the pinky hand and vice versa. The neurologist explained that these alternating coordination drills help stimulate brain activity because they require concentration, rhythm, and continuous adjustment.
While Dr Malhan did not present these exercises as a cure for dementia, his message focused on prevention, early brain engagement, and maintaining cognitive activity through small, consistent habits.
