The Rights of Persons with Disabilities Act 2016, states that a disability assessment can be conducted to assess cognitive impairment for people with chronic neurological disorders. Based upon the results of this assessment, a nominal state pension can be received from the government (Government of India, 2016). Other schemes are listed in Part 9.
