Will a mri be able to show early onset frontotemporal dementia? my mother has been diagnosed with ftd and i want to know if i have the same condition .

Diagnosis: A pattern of atrophy characteristic of different dementias may well be visualized with MRI. Early on, it may be difficult to appreciate subtle changes, and films may be read as normal. A PET scan can detect early metabolic changes, but is very expensive. There is no successful treatment for FTD currently, and it is unlikely that MRI changes will allow accurate prediction of timing or severity.

Maybe, maybe not : The MRI is not the patient; you are. Ditto for your mother. If your MRI showed changes consistent with FTD but you have no symptoms, would you live your life differently? If you developed deficits like your mother's but your MRI was normal, would you ignore your symptoms? These are the questions you must consider. The utility of a test depends on whether the test results will change anything.
