Hyperthyroidism Signs and Symptoms in Older People

An overactive thyroid is more common in people over age 60. Hyperthyroidism in this age group is sometimes misdiagnosed as depression or dementia because older adults do not always display the more common signs of the condition.
For example, older adults may lose their appetites, whereas younger people tend to have increased appetites. Older adults with hyperthyroidism may seem disinterested or withdraw socially. They may have different physical symptoms as well.
In older people with hyperthyroidism, symptoms and signs that are more likely include:
  • Rapid heart rate (tachycardia)
  • Heart palpitations
  • Irregular heartbeat (atrial fibrillation)
  • Extreme shortness of breath with exercise
  • Swelling
  • Weight loss.
In the most extreme situation, known as apathetic thyrotoxicosis, an older person may have no symptoms except for weakness and a lack of energy.
