I often encounter patients in the clinic, when diagnosed with Alzheimer’s disease, family members are very difficult to understand and accept the fact, often think that the patient is just old and confused. One of the misconceptions: “old and confused” is normal Although aging is an important risk factor for dementia, dementia is not an inevitable result of the aging process. About 20% of people over the age of 80 have dementia, which means that 80% of seniors do not suffer from the disease, which means that “old fogginess” is not normal and is likely to be Alzheimer’s disease. Myth #2: Memory loss is due to age At any age, poor memory is not a normal phenomenon and the reason should be found. Stress, tension, and lack of sleep can all cause memory loss. Although there can be a slight decrease in memory and reaction speed as we enter old age, this usually does not affect daily life. Myth #3: There is nothing doctors can do about dementia For mild to moderate dementia, medications can be helpful. Experts believe that the key to the prevention and treatment of Alzheimer’s disease is early diagnosis, and that early drug intervention can stop the further development of the disease and make the patient’s life more comfortable.
