Hypothyroidism can mimic Alzheimer's symptoms, misdiagnosing patients

Hypothyroidism affects about 5% of Americans, or roughly 16 million people. It occurs when the thyroid gland does not produce enough hormones, leading to various health issues, including cognitive decline. Symptoms can be mistaken for Alzheimer's disease. Cognitive issues linked to hypothyroidism include memory loss and lack of focus, often described as "brain fog." These symptoms can mislead individuals into thinking they may have dementia. However, they may actually stem from low thyroid function. Diagnosis typically involves a blood test measuring T4 and TSH levels. Treatment with thyroid hormone replacement can improve symptoms and cognitive function. Hypothyroidism is a common cause of reversible dementia, highlighting the importance of accurate diagnosis.
