... a prescription for it ever since. I've tried many different SSRIs to help with the OCD, but nothing has really worked. I have very bad intrusive thoughts. I've used the Ativan almost exclusively at night, to help calm down the worries I accumulate during the day. I take 1.5 to 2 mg. around bedtime, and have done this particular dosage for several years. I'm now terrified because I've read the recent reports linking Benzo use to the onset of dementia. My question: does anyone else have a LONG term history of benzo use, and are you also concerned about the dementia risk? Many Thanks, Dave
