Q: Is it possible that fish oil supplementation could help neurological disorders like obsessive-compulsive disorder or Tourette's syndrome? If so, how does it specifically help the brain that goes awry in these disorders?
A: Both conditions are due to neural miscommunication. Although there is no published research on the benefits of high-dose fish, both conditions are usually co-morbid with other neurological conditions, such as depression, which responds very well to high-dose fish oil. I would suggest between 10-15 grams of EPA and DHA per day for 30-60 days to see if improvements are noted.
