There are many disorders that may affect thyroid hormones in adults. The most common are:
acromegaly
Myxedema
hyperthyroidism or hypothyroidism
Thyroid diasease
Sleep terror disorder is most common in children four to 12 years old and is outgrown in adolescence. It affects about 3% of children. Fewer than 1% of adults have the disorder. In adults, men and women are equally affected.
It's pretty rare. When it does occur it's almost always in women, although there are some exceptions.
Some symptoms of Attention Deficit Disorder in adults include difficulty focusing, being disorganized, impulsivity, forgetfulness, and difficulty completing tasks. Adults may also experience challenges with time management and decision-making.
Hypersomnia can affect individuals of any age or gender, but it is more commonly diagnosed in young adults. There may be a genetic component to hypersomnia, as it can run in families. Additionally, individuals with certain underlying medical conditions or mental health disorders may be at a higher risk of developing hypersomnia.
The thymus and pineal gland
Less secretion of thyroxine gland can cause dwarfism and mental retardation in the children and this condition is known as Cretinism and in adults if it is not working properly then a person becomes sluggish
Dyspraxia is a disorder affecting fine and gross motor coordination in children and adults. This disorder is a developmental coordination disorder.
Thyroid diasease
The thyroid is a butterfly shaped gland located in the neck, behind the larynx. The whole body is affected by the hormones secreted by the thyroid gland; therefore it is difficult if not impossible to say that the thyroid has an effect on one organ, more than another. The hormones produced by the thyroid regulate most of the body's organs; the pituitary gland regulates and monitors the amount of the thyroid's hormone levels; telling it what to product, release and store. Too much thyroid hormone, as well as too little, can have an effect upon the body and how it functions. So when the thyroid is functioning well, the whole body is well; but as a thyroid problem develops the body can become ill, and in some cases even die.If the thyroid functions as it should, it regulates the rate of the body's metabolism, the rate of growth, body weight, body temperature, skeletal and muscle strength, heart-rate, breathing, blood pressure, cholesterol levels, brain development, nervous system, concentration, energy level, immune system, condition of tissues, skin and hair. Another primary function of the thyroid is the conversion of iodine into hormones that are used throughout the body, these are thyroxine and triiodothyronine; and if the thyroid is functioning well, it inhibits the production of thyrotropin and thyrotropin which can have a negative effect on the body's organs.There are several thyroid hormone disorders/diseases, some of these are Graves disease (those most affected are 30-50), Autoimmune thyroid syndrome/condition (affecting mostly women), Hashimoto's thyroiditis (one of the autoimmune disorders), Papillary thyroid cancer (most common type of thyroid cancer, and readily spreads to other organs), general Thyroid Endocrine cancer (occurs most often after 40 and is one of the most common endocrine cancers), (Addison's disease - there is a connection between the thyroid pathology and some individuals with Addison's disease), Thyroid Nodules (middle aged women are most effect and most nodules are non-cancerous), Thyroid Eye disease (found most in smokers with thyroid disorders/diseases, including those with Graves disease), Hyperthyroidism (called "overactive thyroid," the thyroid makes excessive hormones), Myxedema Hypothyroidism (can result in coma, even death)…
