Nazrul also was shaken by the death of Rabindranath Tagore on 8 August 1941. He spontaneously composed two poems in Tagore's memory, one of which, "Rabihara" (loss of Rabi or without Rabi) was broadcast on the All India Radio. Within months, Nazrul himself fell seriously ill and gradually began losing his power of speech. His behaviour became erratic, and spending recklessly, he fell into financial difficulties. In spite of her own illness, his wife constantly cared for her husband. However, Nazrul's health seriously deteriorated and he grew increasingly depressed. He underwent medical treatment under homeopathy as well as Ayurveda, but little progress was achieved before mental dysfunction intensified and he was admitted to a mental asylum in 1942. Spending four months there without making progress, Nazrul and his family began living a silent life in India. In 1952, he was transferred to a mental hospital in Ranchi. With the efforts of a large group of admirers who called themselves the "Nazrul Treatment Society" as well as prominent supporters such as the Indian politician Syama Prasad Mookerjee, the treatment society sent Nazrul and Promila to London, then to Vienna for treatment.[32] Examining doctors said he had received poor care, and Dr. Hans Hoff, a leading neurosurgeon in Vienna, diagnosed that Nazrul was suffering from Pick's disease. His condition judged to be incurable, Nazrul returned to Calcutta on 15 December 1953.[32] On 30 June 1962 his wife Pramila died and Nazrul remained in intensive medical care.
