Frontotemporal dementia

Frontotemporal dementia refers to middle-aged and elderly patients who are slowly experiencing personality changes, speech disorders, and behavioral abnormalities. Neuroimaging shows frontotemporal atrophy, and pathological examination does not find Pick bodies and Pick cell dementia syndrome. Pick disease and frontotemporal dementia are difficult to distinguish without pathological evidence. At present, it is advocated to classify Pick disease as frontotemporal dementia. Clinical studies have found that frontotemporal dementia is probably the most common neurodegenerative dementia syndrome after Alzheimer's disease, accounting for about a quarter of all dementia patients. Some people think that frontotemporal dementia actually includes Pick disease with pathological Pick bodies, and other Pick syndromes with similar clinical manifestations without Pick bodies, the latter including frontal dementia and primary progression Sexual aphasia (primary progressive aphasia) and so on.
