Marilyn F. Pollin, 62, a Bethesda psychotherapist and psychiatric social worker, died of cancer Oct. 23 at her home in Bethesda.

Mrs. Pollin, who came here in 1956, was a native of Brooklyn, N.Y. A graduate of Adelphi College, she received a master's degree in social work from the University of Pennsylvania.

She was trained in the philosophy and psychotherapeutic methods of Otto Rank, the Austrian pupil of Sigmund Freud who developed a therapy at variance to Freud's and based on greater emphasis on will and individual choice.

In 1976, she became a founder and president of the Otto Rank Center in Washington. She also had served on the national board of the Otto Rank Association.

Mrs. Pollin, who had multiple sclerosis for 30 years, applied her training in combating the disease in herself and others. At one point, the disease left her bedridden, able only to crawl, with extreme dizziness that left her nearly unable to communicate.

She came to lead an active life, engaging in the private practice of psychotherapy from 1967 until her cancer was diagnosed about three months ago. She was cofounder and chairman of the Brief Therapy Service, and in 1981 founded the MS Roundhouse and served as its director. In 1967, she helped found the D.C. Institute of Mental Hygiene.

Mrs. Pollin maintained that the therapy she advocated was not a substitute for conventional treatment of MS, but an adjunct. Her therapy included exercises such as yoga, meditation for stress management, and "imaging," or picturing an illness and its healing in one's mind.

MS is a condition involving inflammation of nerve sheathing that interrupts neural messages. The course of the disease is in many ways unpredictable and erratic. While symptoms can be treated, it is incurable.

Mrs. Pollin was a consultant to the Washington Lighthouse for the Blind.

Survivors include her husband, Dr. William Pollin of Bethesda; a son, Dr. David Joshua Pollin, an Army captain stationed at Fort Carson, Colo.; a daughter, Laura JoAnne Herzog of Ber Sheza, Israel; a brother, Dr. Bernard J. Federman of Forest Hills, N.Y.; and three grandchildren.
