The short answer
Here's the honest answer most websites dodge: serious events after neck manipulation are extremely rare, and the best-known population study (Cassidy 2008, Spine) found stroke association was similar after chiropractic visits and after regular doctor visits — suggesting patients with an artery problem already in progress seek care for the neck pain it causes. Causation is considered unlikely; screening still matters, and we do it.
The full picture
The concern involves the vertebral arteries, and the Cassidy study's insight was elegant: if manipulation caused these strokes, chiropractic visits should carry more risk than GP visits — they didn't. People with a dissection-in-progress get neck pain and headaches, and they take those symptoms to whichever provider they use.
What that means practically: the screening burden is real for every provider who sees neck pain. Our new-patient examination includes the history and risk-factor screening that flags suspicious presentations for medical evaluation instead of adjustment — sudden severe unfamiliar headache, certain patterns after trauma, and other findings we take seriously.
And if you're simply nervous about neck manipulation: say so. Lower-force techniques exist and work well for many patients — comfort with your care is part of its safety.

“I’ve been seeing Dr. Bader for the last 15 years. He is extremely knowledgeable and has a great bedside manor. The office is very well run… Most insurance is accepted and if it’s not, the cash plan is very reasonable. Walk in’s are acceptable and same day appointments are most likely.”
