Manon, I have had two patients with chiari malformation. One responded beautifully to chiropractic, (but hadn’t had any surgeries) less headaches, dizziness, migraines, and brain fog. We started with gentle and then more standard manual adjustments. She has been 10 years under care, rarely any symptoms and now the doctors think it was a misdiagnosis. Her mother was diagnosed with the same condition and after seven surgeries ended up in a nursing home in her late 40s and passed away at 57. She was like a zombie in hospital. My patient believes if her mum had have had Chiropractic care she wouldn’t have ended up with the surgeries and in a nursing home. The other patient was 12, could only go to school for an hour at a time, had extreme visual and auditory sensitivity, and whopping daily headaches. I used No manual cervical adjustments but eventually gentle toggle, prone drop and internal cranial’s. She is now back playing Netball, back at school full time and doesn’t get headaches or dizziness anymore. I saw her Post decompression surgery initially but she was still having all of the symptoms listed above post surgery. I would start with very gentle cervical adjustments in particular but at least 2-3x week depending on her sensitivity. Basic internal cranials will help too. Crazy stuff like this responds BEAUTIFULLY to chiropractic care. Expect miracles!!
