No, not everyone with Mild Cognitive Impairment will develop Alzheimer’s disease or dementia.
Here is the good news:
1 out of 5 people diagnosed with MCI will go back to normal cognitive functioning within 3 – 4 years of their MCI diagnosis
Many people with MCI remain stable for several years without progressing to Alzheimer’s disease or dementia
Some other facts:
Long-term studies suggest that 10-20% of people aged 65 and older may have Mild Cognitive Impairment
As many as 15-20% of these individuals progress from MCI to exhibiting the symptoms of dementia (Alzheimer’s disease) each year. This is compared with 1-2% of the general adult population.
