Overactive Thyroid Symptoms in Older People

Overactive thyroid is more common in people over age 60. This condition is sometimes misdiagnosed in this age group as depression or dementia because older adults do not always display the more common symptoms 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 overactive thyroid, symptoms and signs that are more likely include:
  • Rapid heart rate (tachycardia)
  • Heart palpitations
  • Irregular heartbeat (atrial fibrillation)
  • Shortness of breath with exercise
  • Swelling
  • Weight loss.
In the most extreme situation (known as apathetic thyrotoxicosis), an older person may have no signs except for weakness and a lack of energy.
