We noticed my mother - who is in the early stages- and takes Ebixa -started to lose weight just after being diagnosed with AD. She has always had a healthy appetite and so Dad took her to the GP for tests. Nothing showed up as being unusual so it's a mystery. She's still underweight but thankfully, doesn't seem to have lost any more weight. I too have read that this symptom affects the later stages so we're at a loss as to why it's happened so soon.
