A patient presenting with suspected Pick's disease may be diagnosed with frontotemporal dementia using imaging tests for definitive diagnosis after physical and neurological examinations. Depending on the results, a person may be diagnosed with behavioral FTD or one of the subtypes of primary progressive aphasia (PPA). To diagnose FTD, blood tests, cerebrospinal fluid tests, computed tomography (CT), electroencephalogram (EEG), genetic testing, magnetic resonance imaging (MRI), and positron emission tomography (PET) scan are performed.
