Just replying to Bobby, who has "multiple episodes daily" and has been told that "nothing can be done". As far as the multiple episodes are concerned, I'm having an even worse time with my AIWS, as it has been permanent since 2003. Looks like we are in the same boat of having a level of AIWS which has quite a bad impact on our daily lives.
The official line from doctors seems to be "can't do anything and can't be bothered to try and find out". They seem to think that AIWS is a rare condition and that people normally have just a few visual disturbances, which they need to learn to live with. This AIWS Groups site is really important, because it shows that it is actually a reasonably common condition and is affecting a lot of people. Also, there are people like Bobby and me, where the AIWS is very frequent, or else permanent. I did once come across a man on a thread on another AIWS website, who said he had been putting up with permanent AIWS for the past 30 years.
It would be good if the doctors and researchers would do a bit more research. What they do know is that AIWS involves a lack of oxygen flow to certain areas of the visual cortex involved with the processing of visuo-spatial information. It seems to me that it would be worth investigating what is causing the lack of oxygen. We know that arteries are becoming blocked for heart conditions and strokes, so is this part of what is happening in AIWS? I have recently been for a health check and was told that my cholesterol is too high. The reading for cholesterol was 7.1 and it should be 5. There was also an abnormality with the ratio of HDL (good cholesterol) to LDL (bad cholesterol). The reading for that 7.1 and it should be 5.1. I've been told to stop eating chocolates and crisps, reduce saturated fats and sugars in my diet and keep red meat to two servings per week. Also been told to do more exercise. My blood pressure, BMI and creatine level were all fine, but I've been advised to try and get my weight as good as possible and exercise most days. I've been told I have a 7.4% overall risk for heart attack or stroke and the normal age for my age group is 6.7%.
I was only given this information a couple of weeks ago, but I'm trying to improve a bit. Found some prawns I like at Marks and Spencers, so I'm having smokey prawns and salad quite a lot instead of meat. It's very hard for me to give up on chocolate and crisps, as I was eating them most days, but I've tried eating things like grapes and slices of watermelon instead.
With the AIWS, it's probably not just the cholesterol. I've had AIWS for years, and it was there even when my cholesterol level was good. When I was young I used to have chronic migraine and migraine involves a lot of expanding and constricting of blood vessels. I suppose, since the AIWS for me is permanent, it may be that some of the blood vessels supplying the back of the brain may have collapsed, or else have become quite blocked.
I'm on an IT course at the moment and that involves a lot of sitting at the computer. Of course, it's Saturday now and what am I doing ... you get the gist! Think I'd better get myself a new pair of trainers and try a bit of jogging by the side of the local river. The NHS do a useful podcast called "Couch to 5K" which is supposed to help you to increase your running in stages, so I might have a go at that. I haven't been to the gym for ages, but might give it a try.
I think for all of us, it might help to orient to the kind of diet and exercise which is going to help with good blood flow to the brain. The oxygen also sounds a good possibility, but maybe we all need to look at our personal medical history and try to work out why there might be poor blood flow to the visuo-spatial processing areas in the brain.
We need to get some relevant people interested and on our side, so maybe we should get together a list of experts in relevant areas, including migraine and AIWS. I have collected quite a lot of articles on AIWS and on diet and health issues in general, so I probably already have some relevant names. I'll have a look later on and post back on this.
Anyway, I'm off to the cinema to see the new Fantastic Beasts film this afternoon. Sigh ... yet more sitting! 😇
