Frontotemporal lobar dementia is usually not curable, but active treatment can reduce symptoms and slow disease progression. Frontotemporal lobar dementia is a type of degenerative dementia, the pathogenesis of which is not entirely clear, and there are no specific drugs. As the disease progresses, progressive neurological damage occurs, leading to a wide range of high-level cortical dysfunction. The cognitive dysfunction caused by frontotemporal lobe dementia cannot be reversed, such as memory impairment, reduced learning ability, reduced ability to perform daily life, personality changes, mental abnormalities, etc., and can only be treated symptomatically. If the diagnosis of frontotemporal dementia is confirmed, it should be treated actively. Treating the disease as soon as possible can control the progression of the disease or slow down the progression of the disease, and improve the quality of life of the patients.
