The theme for the 6th semester was "Design of health science technology systems", which in some cases where continuation of analyses made on the 5th semester. The project I participated in on the 6th semsester was a continuation of a analysis made on the 5th semester, on the department of Neurosurgery.
Normal pressure hydrocephalus (NPH) is a condition where peoples brain are affeteced due to a raise in the intercranial pressure (ICP). It givessymptoms like walking disability, dementia, depression and so on. The thing is that the pressure i not unnormal high, its as NPH says normal, but to high. By inoperating a valve NPH can be cured, both inoperating a valve is not without complication, so if it's not NPH but some other dementia disease you don't want inoperate the valve.
In order to diagnose NPH you meassure brain waves, and the doctor looks for specific brain waves to figurer out if it is NPH. We made a system called Dikti which digitized these brain waves and also helped in finding the brain waves the doctor looks for. You can read more about the project here. (Sorry only in danish)
