On cfs & 'brain fog': any neurology ideas? mds tried modafinil; little help & out of ideas. memory/concentration: always v. bad; worse with less sleep

It's complicated but: Brain fog is common in CFS. It's important to address the cause; many have undiagnosed Lyme disease and/or other infections; in that case need to treat those- see http://tinyurl.com/zlrz84j and http://tinyurl.com/y88wusc9 Possibly nutrient deficiencies (like B12),hypothyroidism, heavy metal toxicity,food sensitivities etc. Herbs like Bacopa, Ashwagandha, Turmeric may help. See good integrative Dr.
