CLOSE-UP Tay, Sachs ordeal ADRIEN CHANDLER Special to the Jewish News • A ndrea was a beautiful baby — happy, smiling, with a sweet face, porcelain skin and large soft eyes fringed with long, dark lashes. Her mother says she was the kind of in- fant who woke up pleasant and hard- ly ever cried. "She was almost too good to be true;' says Thresa Yerman of Livonia. Terri knows what kind of tragic irony that statement holds, because her daughter Andrea was a victim of Tay-Sachs disease — an incurable and deadly nerve disorder that robs its victims of their senses, their muscles, their minds and eventually, their lives. Andrea only lived to be 4 years old. Tay-Sachs is rare, though the car- rier rate among Jews of Eastern Euro- pean or Ashkenazi origin is approx- imately one in 25 and 10 times higher than in the general population. Na- tionwide, over a 15-year period (1969-1985), only 550 high-risk couples, where both mates have the trait, were found. In Detroit, seven high-risk couples have been found since screening began in the early 1970s, says Pat Christoferson of Henry Ford Hospital's genetics program. Of those couples, there were only six Tay-Sach pregnancies. That's out of more than 7,000 people who have gone through a Tay-Sachs screening. With heavy screening, the in- cidence of Tay-Sachs disease in the Jewish population has declined significantly. But many people false- ly believe that marriage to a non-Jew means they can escape Tay-Sachs. Medical experts, and Terri Yerman, know that's not true. Terri is not Jewish, but her ex- husband Ronald is. When they mar- ried in 1969, there was no indication of Tay-Sachs in his family and, they thought, no reason to worry about hers. Their daughter Andrea was born in 1972 while the couple was liv- ing in Toledo. . When Andrea was nine months of age, Terri began to notice problems. The baby wasn't focusing, sitting 22 FRIDAY, JANUARY 13, 1989 Several Detroiters have endured the agony of bearing a doomed child. upright very well or crawling. Terri was concerned, but doctors had told her in earlier exams that Andrea was just developing slowly. Andrea's condition was finally diagnosed in Cleveland. Ron mention- ed to an opthamologist that the baby seemed to be having vision problems. The doctor, looking into Andrea's eyes, was startled to find something he had never seen in 30 years of practice — cherry colored red spots on the retinas which are a strong indication of Tay- Sachs disease. Subsequent tests at Cleveland Clinic confirmed the diagnosis and the Yermans' worst fears — their daughter had an incurable and dead- ly disease. The awful truth sank in as the Yermans examined their options. As with most Tay-Sachs cases, the doc- tors recommended institutionalizing Andrea, but the Yermans decided to keep the baby at home. "I felt I could give her a lot more attention and love at home than in a hospital!' says Terri. By this time, the Yermans had moved to Ann Arbor. Even though Terri had some nursing background, she admits it was rough to care for her own terminally-ill child. Andrea was being fed intravenously through a tube down her nose. She had lost her ability to swallow and had to be suc- tioned regularly — every night, every hour. The worst part, says Terri, was watching Andrea's senses dwindle — her hearing and eyesight. "When she first went blind, it was terrible. I remember crying . . . and thinking 'I'm going to have a blind daughter! And then I thought, 'Going blind would be simple compared to what's going to happen! We used to hold her and touch her and hoped she sensed we were there . . . I was almost grateful when she lost her hearing. She had hyperacusis (ultra-sensitive hearing). Even rattling a teacup would make her jump!" Andrea's long, slow deterioration took a heavy toll on Terri and her hus- band, who traveled much of the time. There were arguments, some about euthanasia, because Ron couldn't stand to see Andrea suffer. "It was so difficult. There were times he wanted to overdose Andrea. In my mind, I couldn't accept that. After she died, he thanked me for not allowing him to do it!' There were the usual feelings — the guilt, the blaming, the anger at why this had to happen to them. Terri would look at friends' children — hap- py, healthy and developing normally — and feel pangs of envy while her daughter was slipping away. Terri sought counseling as a way to channel her anguish and adjust. She says Ron's family accepted and dealt with the situation, but her own could not believe that she had con- tributed to Andrea's illness. In fact, when Terri begged family members to get tested for Tay-Sachs, many did not. When Andrea was 2 years old, the Yermans decided they would try to have another child, knowing full well that this baby could also be affected. While pregnant, Terri underwent am- niocentesis and wrestled with the question of possibly having to abort the fetus. In spite of what they had been through, she doubted she could do it. Finally the word came: she was carrying a normal, healthy baby girl. Daughter Joy was born in July 1975. The Yermans had considered adop- tion, but were told they would have to institutionalize Andrea first, and they would not. Joy was 18 months old when An- drea died of cardiac arrest in January 1976. A month before, a weary Terri had stood beside Andrea's bed, look-
