I have lots of experience with the issue since I have experimented extensively with veganism (6 years) and am now currently ovo-vegetarian. The secret to preventing brain health deterioration for vegans, vegetarians, and meateaters is getting sufficient levels of omega 3 and omega 6 fats...particularly the omega 3s. In order to do veganism successfully long-term one should consume lots of flaxseed oil or ground flaxseed because of its super high content of omega 3s. Also, you should be supplementing with B12 and perhaps other B vitamins. One way to supplement B12 in non-pill form is to eat lots of nutritional yeast.
$this->bbcode_second_pass_quote('', 'T')he brain is remarkably fatty: In fact, this organ is 60% fat and needs omega-3s to function properly. Now researchers have discovered a link between mood disorders and the presence of low concentrations of omega-3 fatty acids in the body.
Omega-3 and 6 fats move into cell membranes, particularly the membranes of nerve and epithelial cells. Epithelial cells compose skin, the lining of the arteries and lungs, the linings of the ducts in the breast and testes. The preferential fat for these brain and epithelial cell membranes is omega-3 but n-3 will be replaced by n-6, if n-3 is not available. Cells where omega-3 is displaced by omega-6 are less able to repair themselves and may become hyperplasic.
The brain and nerves so need omega-3 that they will rob it from every other cell to maintain optimum brain levels. Some of the brain and nerve conditions associated with high omega-6 and/or low omega-3 include, alcoholism, depression, manic depression, memory loss, impaired night vision, anxiety, insomnia, dementia, Multiple Sclerosis, Alzheimer’s, Parkinson’s, ADD, ADHD, dyslexia, stress induced hostility and schizophrenia.
Apparently, omega-3s help regulate mental health problems because they enhance the ability of brain-cell receptors to comprehend mood-related signals from other neurons in the brain. In other words, the omega-3s are believed to help keep the brain's entire traffic pattern of thoughts, reactions, and reflexes running smoothly and efficiently.
Clinical trials are underway to further investigate whether supplementing the diet with omega-3s will reduce the severity of such psychiatric problems as mild to moderate depression, dementia, bipolar disorder, and schizophrenia. Interestingly, the oil used to help the child with a degenerative nerve disorder in the popular film Lorenzo's Oil was an omega-3 fatty acid.
