The disease referred to as dementia mainly refers to Alzheimer's disease. Only a very small number of cases are hereditary, where patients have a certain family history caused by genetic mutations, thus having some hereditary traits. However, the vast majority of Alzheimer's cases are sporadic, unrelated to genetic mutations, and these sporadic cases are not hereditary, so there is no need to worry about transmitting it to offspring. Nevertheless, it is important to note that, with the progression of population aging, the incidence of this disease remains relatively high, especially for those over the age of 65, who need to pay close attention to this disease. If a patient exhibits a decline in memory function, do not assume it is just forgetfulness; it is crucial to visit a hospital for diagnosis and timely treatment.
