Does Hypothyroidism Cause Brain Fog?
Yes, hypothyroidism commonly causes brain fog and cognitive difficulties. When your thyroid doesn't produce enough hormones, it slows down your metabolism and affects brain function. Studies show that up to 90% of people with hypothyroidism experience memory problems, difficulty concentrating, and mental fatigue. The brain fog typically includes trouble finding words, reduced processing speed, and difficulty multitasking. Thyroid hormones are essential for proper neurotransmitter function and brain energy metabolism. Most patients notice significant improvement in cognitive symptoms within 2-3 months of starting thyroid hormone replacement therapy.
