ON the heels of the panic in Europe following the discovery of 10 cases of Creutzfeldt-Jakob Disease (CJD), the human equivalent of 'Mad Cow disease', has come the revelation that 30 cases of CJD have been recorded in India between 1971-1990. A pilot study at the National Institute of Mental Health and Neuro-sciences (NIMHANS) found 20 'definite' and 10 'probable' cases of CJD, mostly from Bombay and Bangalore, cities which have a concentration of neurological diagnostic facilities. And as awareness grows, the number of reported cases is expected to increase. However, NIMHANS neurologists and Health Ministry experts assert that there is "no cause for alarm" as the risk of contracting CJD is one in a million.
