Thyroid dysfunction is common, produces cognitive symptoms, and is one of the simplest things to rule out.
What it does
Thyroid hormones affect metabolic rate throughout the body including the brain, and receptors are widely expressed in neural tissue. Hypothyroidism is associated with slowed processing, poor concentration, memory complaints, fatigue and low mood — a symptom cluster overlapping substantially with both depression and early cognitive decline. Hyperthyroidism produces anxiety, restlessness and concentration difficulty, and in older adults can present atypically with apathy.
Why it is missed
The symptoms are non-specific and easily attributed to stress, ageing or overwork. Onset is gradual. It is more common in women and prevalence rises with age, overlapping with the population most likely to attribute symptoms to normal ageing. Subclinical hypothyroidism — raised TSH with normal thyroid hormone levels — is common and its cognitive significance is debated, which adds interpretive difficulty.

A TSH test is inexpensive, widely available and part of most basic panels. Treatment of overt hypothyroidism generally improves symptoms including cognitive ones. Whether treating subclinical hypothyroidism improves cognition is less clear and trials have been largely unsupportive in older adults. Relevant to this site: ashwagandha, which appears in some nootropic formulas, can affect thyroid hormone levels, which matters both for people with thyroid conditions and for anyone whose test results might be altered by it.
Key takeaways
- Hypothyroid symptoms overlap substantially with depression and early cognitive decline
- Onset is gradual and symptoms are easily attributed to ageing or stress
- A TSH test is inexpensive and part of most basic panels
- Ashwagandha can affect thyroid hormone levels
