A pioneering [WORD ILLEGIBLE] study of 7 victims conclude [WORD ILLEGIBLE] prolonged mental disturbance is [LINE ILLEGIBLE] then three-quarters of the [WORD ILLEGIBLE] suffer from anxiety depression, irritability, speech difficulties, loss of memory, inability to concentrate, sexual disturbance, lethargy, nightmares or headaches.

Whether they can ever be treated successfully, the report says, "is uncertain."

The study was released today by Amnesty International, a volunteer group campaigning against abuses of political prisoners all over the world. The Danish team began its inquiry three years ago under Dr.Inge Kemp Genefke, a neurologist at University Hospital, Copenhaven.

As far as is known, this is the first scientific study of torture techniques and their consequences.

The principal study examines 32 Chilean torture victims who found refuge in Denmark and 35 Greeks who had been tortured under the former military government. Most of the Chileans, men and women, had been subjected to eletric shock on the ears, nose, mouth and genitals. Nearly all the Greeks had been beaten with canes on the soles of their feet.

Nearly all in both groups were beaten and burned with cigarettes on the hand or forearm. One victim was [WORD ILLEGIBLE] between Chileans and Greeks display some symptoms of mental disturbance. Fifteen have impaired hearing. Most of the Greeks suffer ankle and knee pains from the foot beatings.

Dr.Genefke's team thinks it can link specific symptoms of damage to a particular kind of torture although it calls for "more refined methods of studying the problem."

If this attempt is successful, it will be possible to prove medically claims of torture even where no scars are left.

A second study examines two young Uruguayan men and a woman of 22 who were kidnapped in Argentina and tortured continuously for seven days and nights. They were subjected to a form of torture in which the head is held under water to the verge of drowning; electric shock and beatings. The woman was raped twice in front of her companions.

Again, the Danish team stresses the lasting mental effects on the victims - poor memory, anxiety, depression, sleeplessness and headaches. The three Uruguyans were examined a second time, eight weeks after the first. Many of their scars had disappeared, but the emotional disorders retained.

Dr. Genefke and her team told a press conference here Friday that they hope that medical groups will [WORD ILLEGIBLE] going her countries to carry on the work. A team of psychiatrist's has been formed to examine the Soviet practice of incarcerating political dissidents in mental institutions and administering drugs. Earlier this spring, Amnesty compiled a dossier of Soviet mental-prisoner cases.

The Danish doctors said they are especially concerned about their colleagues who assist in torture, either by recommending the appropriate instrument or determining how much a victim can stand.

"We want torture seen as a disease," Dr. Genefke said. Then doctors who spread rather than contain illness could be isolated professionally from their fellows.
