Senoufou (Eliza) -- Sorry I didn't see your last post in this thread until today. As a matter of fact, my Dad did indeed suffer from vertigo; in fact, vertigo caused his premature death as a result of a fall.

When I was in my teens, both my mother and I sang in the Ottawa Choral Society, and Dad would loyally attend the concerts. During the 1970s, when the National Arts Centre opera house became a popular venue for major classical concerts, I first became aware of my father's vertigo problem when he would be obviously uncomfortable after a concert, and eventually he refused to go -- most unlike him. Though he was no musician, he was the soul of gentility and always supported our efforts. After Mum died, he stopped attending church services with organ music, opting for the 8:30 a.m. "said Eucharist".

In May of 1992, he attended a family wedding with all the Anglican bells and whistles, including a full choir and exuberant organ music. The next day, he was dizzy and sick, barely able to stand up; I remember him reeling around the kitchen. He felt better toward evening and decided to go to the pub for supper, a stroll of about three blocks. On the way home, the dizziness returned, causing him to keel over. He fell at full stretch onto a neighbour's lawn, striking his head on a water shut-off valve sticking up from the grass. He never regained consciousness and died that night.

The vertigo had been gradually getting worse, most often associated with exposure to loud, resonant sound -- such a church organ. In the last years of his life, he avoided all noisy places, including any restaurant or pub with a sound system and/or echoing acoustics. The only kind of music he really enjoyed was unaccompanied singing; even my guitar made him a bit uncomfortable.

At the time of his death, he had an appointment booked with a neurologist to investigate the possibility of an inner-ear problem.
