Statistics show that about 1 in 10 people under 60 who have “brain fog” actually have Early-Onset Alzheimer’s. Most assume “brain fog symptoms” are just a result of chronic fatigue or a heavy week at work, but for many, it’s actually the first sign of cognitive decline. One woman at forty thought she was just being hit by stress, not dementia — until a life-changing diagnosis destroyed her world. These early warning signs were just the beginning of an invisible disease.
