Hello all...good to have stumbled on this site. Hope to give and get some info! Am from the USA (Virginia).
Had known for many years that my paternal grandfather had HHT (as well as a first cousin who suffered from a ruptured cerebral AVM at age 10), but had no personal experience with this until this Feb. Evidently my 84 yr. old father also has this, but thus far is fine except for an occasional nosebleed. Of his 4 kids, I'm the only one who's exhibited any symptoms and this was unexpected (I'm a very healthy 46 yr. old). Suffered a minor stroke. The telangiectases seem to be confined to the brain, although the CT lung scans were iffy. Have had no ill effects thus far other than several creepy deja vu events that are unexplained but have had these for years now. May be unrelated.
Anyway...during the stroke, I had extreme light-headness and a kind of "out of body" experience (autoscopy), plus my left leg suddenly went limp. After several minutes, the affected leg and my stomach muscles violently spasmed and after a time it subsided. Since then am just fine and resumed my moderate physical exercise and work schedule within 4 days of the event. If anyone else has experienced stroke with their HHT, please let me know. Apparently, my brain has several of these smallish telangiectases and unbeknownst to me, one "went off" at an earlier time. Fortunately for me, it seems none will be debilitating or fatal.
