The essence of Deccani culture and dementias


Hyderabadi culture is interpreted in different ways by different people. In the pop culture of today, the city stands for Hyderabadi Biryani, pearls and Charminar. For the upwardly mobile, it is the place for opportunity and growth. Bollywood loves the city for its typical lingua franca – the Hyderabadi. People coming from North India don’t feel out of place because it is not ‘deeply southern’. Hyderabad is perhaps all this and much more. It is difficult to capture the essence of Hyderabad in one word or one sentence.

The best one can get near a definition of Hyderabadi culture is ‘Ganga-jamuni tahzeeb’, which connotes synthesis of different cultures. Hyderabad is truly a melting pot of cultures and languages. Besides Telugu and Urdu, we can find a large number of people who speak Marathi, Kannada and Tamil. For anyone who has grown up in Hyderabad in the 1960s and the 1970s, knowledge of multiple languages became part of the growing up process. Those days it was not difficult to find elders who had studied in Osmania University or the City College in an era when the medium of instruction was Urdu. In lanes and bylanes of Kothi and Badi Chawadi you could hear people talking in Marathi. Further down towards Kachiguda, you could do with smattering of Kannada. Still these languages were not spoken in their pure forms but had a tinge of Hyderabadi. The city truly represented the heart of Deccan.

Multilingualism is the most precious heritage of the Hyderabadi or Deccani culture and it needs to be preserved for reasons other than historical or nostalgic as well. For many years now, Western scientists have been pointing to the important role knowledge of more than one language plays in certain cognitive functions which are critical in onset of dementias. A study published by scientists from York University last year had explained how speaking more than one language may translate into better mental health. It found that being bilingual can offer protection from symptoms of dementia. Previous studies had established that bilingualism has a beneficial effect on cognitive development in children, but this one found out the same is true in adults.Now it is heartening to see similar work done by Indian scientists and that too from Hyderabad, which provides a perfect cultural backdrop for multilingualism.

Scientists from Nizam's Institute of Medical Sciences, working with researchers from the University of Edinburgh, have found that people who speak more than one language and who develop dementia tend to do so up to five years later than people who speak just one language. They examined almost 650 dementia patients and assessed when each one had been diagnosed with the condition. They found that people who spoke two or more languages experienced a later onset of Alzheimer's disease, vascular dementia and frontotemporal dementia. Significantly, the bilingual advantage extended to illiterate people who had not attended school. This means formal education does not make a difference in language learning and its beneficial impact. The impact of bilingualism on the onset of dementia was tested after accounting for other influencing factors like education, gender, occupation and whether they live in a city or in rural areas.

Juggling languages means switching between sounds, words, concepts, grammatical structures and social norms. This acts like a natural training programme for our brain and scientists say that it is more effective than any artificial brain training programme. Lifelong experience in managing attention to two languages activates or reorganizes specific brain networks. This, in turn, results in effective ways for executive control and sustaining better cognitive performance throughout the lifespan. In a way, a multilingual brain is uniquely shaped and differently networked.

Another recent study by American linguists had found that people adept at speaking more languages also possess multi-tasking skills because they are able to mentally negotiate between languages. Multi-lingual persons appear to have special switching skills, when it comes to choice of language at any given time. They can effectively negotiate through competition of languages. The language selection – or code switching in scientific parlance - is actually considered a form of mental exercise. New research has demolished past theories of linguists that learning multiple languages hinders cognitive development in children or that multilingual adults have difficulty switching between languages.

With changing lifestyles and increasing lifespan, India is seeing the rise of dementias. Perhaps it is time to look back. The comment made by Thomas Bak of University of Edinburgh, who collaborated with Suvarna Alladi of NIMS for the study, is eye opening. He says that bilingualism might have a stronger influence on dementia that any currently available drugs. It is time to say cheers to good old Hyderabadi culture and embrace it for the sake of our brains.
