Hi everyone,
Here is a useful article about slow breathing and its benefits against Alzheimer's.

There are believed to be many benefits to slow, controlled breathing. Researchers may have found another – a surprising protection against Alzheimer's.
...inhale slowly, concentrating on expanding your lungs, to a count of five. Exhale, just as slowly and deliberately, as you count to five.
You might find that, in just that 10 seconds, you suddenly feel just a little bit more relaxed or centred. Follow the same practice for 20 minutes a few times a week and – according to the research – you might not just reap the benefits of feeling calmer. You may also be helping to prevent the onset of various diseases, including, a recent study has suggested, even Alzheimer's disease.

Pranayama or breathing control is a part of the Ashtanga Yoga system. Very useful.
Cheers.
