7 key behaviors that could protect your brain from Parkinson’s disease

As the world’s population ages, the prevalence of Parkinson’s continues to increase, and it is estimated that by 2050 there will be 25 million people living with this neurological disease.

This incurable progressive disorder affects motor abilities and other functions of the nervous system, typically causing rigidity, tremors, balance problems and slow movements, along with mood changes, cognitive impairment and sleep disturbances.

Although Parkinson’s usually appears after the age of 60, there are some cases of early onset.

AIR POLLUTION MAY PLAY A BIGGER ROLE IN COGNITIVE DECLINE THAN ANYONE THOUGHT

While aging has been shown to be the most important factor (and family history also increases risk), research has shown that some lifestyle behaviors can help prevent or delay the onset of the disease.

“Today, although it is not possible to prevent Parkinson’s disease, maintaining a healthy lifestyle (staying physically active, eating well and getting enough sleep) can help protect overall brain health and can reduce the risk of various neurological disorders,” Prof. Dr. Pulat Akın Sabancı, Professor of Neurosurgery at Istanbul University, told News Digital.

Below, experts shared some of the most impactful prevention methods.

No. 1: Stay physically active

Regular exercise is strongly linked to a lower risk of Parkinson’s disease, according to Dr. Mary Ann Picone, medical director of the MS Center at Holy Name Medical Center in New Jersey.

“Aerobic exercise can be neuroprotective and improve motor function,” he told News Digital, as studies have shown it reduces risk by 50%.

Picone recommends doing moderate to high intensity activities, such as walking or biking, for a significant amount of time each week (at least 30 minutes a day).

“Aerobic exercise increases heart rate and helps neurons in the brain maintain old connections and form new connections,” he noted.

Weight training and resistance exercises, as well as activities that combine balance, agility and coordination, such as Tai Chi or dance, are also beneficial, according to the expert.

“Research shows that getting the blood pumping helps brain tissue develop protective mechanisms and do better on tests of cognitive and muscle control and often live longer,” he said.

No. 2: Eat a brain-friendly diet

Picone recommends eating a diet rich in antioxidants and plant-based protein sources, especially beans, nuts and tofu, as well as foods rich in omega-3 fatty acids. It’s best to avoid processed foods, he advised.

A Mediterranean or MIND-style diet, rich in fruits, vegetables, olive oil, and whole grains, has been linked to a lower risk of Parkinson’s disease.

“Foods that contain antioxidants are recommended, such as purple, red, and blue grapes; blueberries; red berries, such as strawberries; leafy green vegetables, such as broccoli, kale, and spinach; and sweet potatoes, acorns, or squash,” Picone said.

Coffee and tea drinkers have a lower risk of Parkinson’s disease, the doctor said.

No. 3: Limit exposure to toxins

Exposure to certain environmental toxins, such as pesticides and heavy metals, can damage neurons and increase the risk of Parkinson’s, according to Dr. George Michalopoulos, founder and president of the Neurologic Wellness Institute of Chicago.

“Aerobic exercise can be neuroprotective and improve motor function.”

“While it’s impossible to avoid all toxins, there are steps you can take to reduce your exposure,” he told News Digital. “Choose organic produce when possible, wear protective gear if you work with chemicals, and drink filtered water to avoid contaminants.”

No. 4: Prioritize sleep

During deep sleep, the brain eliminates waste products and repairs itself, Michalopoulos noted.

“Chronic sleep deprivation or conditions such as sleep apnea can increase the risk of neurodegenerative diseases, including Parkinson’s,” he said. “Follow a consistent sleep schedule, avoid screens before bed, and create a relaxing bedtime routine.”

Dr. Vibhash Sharma, a neurologist and medical director of the neuromodulation movement disorders clinic at UT Southwestern in Dallas, Texas, reiterated the importance of quality sleep for Parkinson’s prevention.

“Given that poor sleep quality and chronic sleep deprivation are associated with an increased risk of neurodegenerative diseases, quality and adequate sleep are important to support brain repair and clear abnormal proteins linked to Parkinson’s disease,” he told News Digital.

No. 5: Manage stress

Stress is a part of life, but chronic levels can affect the brain, Picone warned.

“It has been linked to inflammation and oxidative stress, both of which are thought to play a role in Parkinson’s,” he said. “Finding ways to manage stress can help protect your brain and improve your overall health. Try mindfulness practices like meditation, deep breathing, or even a daily walk in nature.”

No. 6: Stay mentally and socially engaged

Keeping the brain active and connected to others can help develop a “cognitive reserve,” which can protect against neurodegeneration, according to Michalopoulos.

“Activities that challenge your brain, like solving puzzles, reading or learning a new skill, are great for keeping you alert,” he told News Digital.

Sabanci reiterated that lifelong learning, social connection, and purposeful activity support brain resilience.

No. 7: Avoid smoking and drinking alcohol excessively

Smoking and excessive drinking have been linked to an increased risk of Parkinson’s, Michalopoulos warned.

“Quitting smoking and moderating alcohol consumption can go a long way toward protecting the brain,” he said.

However, experts agreed that none of these behavioral changes completely guarantee protection against Parkinson’s.

“But together, they form a practical, low-risk approach to supporting brain longevity,” Sabancı said.

“Anyone with motor changes, loss of smell, REM sleep behavior disorder, or persistent constipation should seek early medical evaluation.”
