1. Understanding Thyroid Function A normal thyroid gland is important for the body's growth, behavior, and psychological and neurological development. The main function of the thyroid gland is to produce, store, and secrete thyroid hormones (TH), including thyroxine (T4) and triiodothyronine (T3), and is regulated by the hypothalamic-pituitary-thyroid axis. TH has a role in regulating mood, brain development, neurotransmitters, neuronal differentiation, synapse and myelination, neuroprotection, and brain metabolism. Thyroid dysfunction can lead to neuronal cell death, impaired synaptic plasticity and memory, misfolded protein deposition, oxidative stress, and neurological disorders, which promote the development of AD. 2. Thyroid disfunction Kim [1] selected 1,977 AD patients and 16,473 age- and sex-matched controls from a database of more than 500,000 people from 2002 to 2015, and showed a relationship between thyroid disfunction and the risk of developing AD. The results of the...
