now serving bergen county, nj




Functional neurology is an applied clinical neuroscience that focuses on the scientific study of fundamental mechanisms that underlie disease and disorders of the brain and central nervous system. At Kaplan Brain & Body, we use this safe, gentle and effective non-invasive technique to keep your brain, spine, nerves, and energies functioning without interference or imbalance that helps to strengthen weak areas of the brain and turn on your body’s natural healing power. What sets functional neurologists apart from conventional medical practitioners is the approach to treatment. Our providers will get to the root cause of your problems rather than just treat symptoms with medication or surgeries.

Dr. Kap is incredible, young knowledgeable empathetic and a great resource. i’ve seen him for years for a number of auto inflammatory induced CNS imbalances. he is a vault of knowledge for nutritional and supplementation ancillaries for healing metabolic imbalances, which years of trial and error and my own immunologist (Jesse Stoff in Westbury) has helped me find some balance.

Rosa P.

Dr. Kaplan treats his patients holistically rather than just treating the symptoms. He really understands how to heal the body in ways other doctors haven’t been able to. He doesn’t just throw meds at you. I highly recommend him.

Jessica P.

My daughter sees Dr. Kaplan, he is great with kids! Very welcoming office, Dr. Kaplan is an awesome dr, very genuine and knowledgeable. He is truly invested in others’ well-being.

Mary C.

I was referred to Dr Kaplan from another healer. Having dealt with a disease for 27 years. His intensive approach through the neurological functioning work has been astounding the results in a short order. And as we go he explains everything and holistically knows how to include insight in diet and supplements.

Kemiesha B.

Can you imagine being in constant pain for 10 years? Sleeping for not more than 4 hours a night for 6 years? I can, because that was my life before I saw Dr. Kaplan. I went for a consultation and I left his office 1 hour later feeling like I got back my life. I slept for the first time in a long time through the night that very same evening.

Susan D.

Ultimate Professional I have had regular appointments with Dr. Kaplan since last year for a serious vasovagal condition, among other issues. Dr. Kaplan is a very knowledgeable and cutting edge functional neurologist. He always takes his time at my visit, and never fails to demonstrate both his expertise and compassion.

Lalena L.

Effective & unique I discovered Dr. Kaplan at a Health Expo in the fall, and have been coming since beginning of January. I had a setback from a 2 year old knee injury where I had chronic leg pain for weeks from hip to ankle, so bad that it kept me up at night. I also had long term stomach issues. I like that Dr. Kaplan looks at your ailments holistically, it is not just about getting an adjustment.

Shirley C

Dr. Kaplan and staff are very professional Dr. Kaplan treat my individual problems: balancing my left and right brain and strengthening my vagus nerves with specific exercises. I even get home assignments to do at home. My processing time for my brain is very slow and he does not get impatient even though I was a dodo bird.
