Sayomdeb Mukherjee was born into a joint family in Kolkata in November 1980. Like any other toddler, Mukherjee, fondly named Den, would crawl around the house and make the family laugh with his antics. But over time, his muscles started to contract and by the age of five, his speech got affected as well. Den was apparently born with a rare genetic disorder, Dopamine-Responsive Dystonia, as a result of which he was non-verbal till the age of 25. Despite all disabilities, 41-year-old Den has essayed various roles and today, he is an author, award-winning actor, a radio jockey and is even helping other people with disabilities overcome their challenges and lead fulfilling lives. Here's his story.
