FOUR years ago, a modest beginning was made at this experimental facility in New Delhi—a beginning that should turn into a full-scale war against sleep disorders. To exorcise the demons haunting the nights of a growing number of victims, Dr J.C. Suri's laboratory employs, primarily, a sleep machine. Essentially, this machine monitors the quality of various stages of a patient's sleep, together with indicators such as blood pressure and brain and muscle activity that have a bearing on sleep. Measurements taken, the patient is put on medication or therapy or both.
