The reasons for the difficulty in speaking are cerebrovascular diseases, dementia, neurodegenerative diseases and so on, as follows: First, cerebrovascular diseases: mainly seen in various cerebral infarcts, cerebral hemorrhage and so on, patients often have aphasia and will have more effort in expressing themselves, which is one of the main reasons. Second, dementia: Now that our country is entering an aging society, the incidence of dementia is getting higher and higher, and we often see many elderly people having difficulty speaking and struggling to express themselves. At this time, it is necessary to go to the neurology department of the hospital to do a check of the relevant scale to assess whether there is dementia. If dementia is present, early pharmacological intervention is required to slow down the progression of the disease. Third, neurodegenerative diseases: such as Parkinson’s disease, amyotrophic lateral sclerosis, etc. Neuronal degeneration can lead to paralysis of the muscles in the throat, resulting in labored speech and difficulty.
