Diabetes Insipidus

Diabetes insipidus is a uncommon condition characterized by the body's inability to retain enough water to meet its needs. Usually the hormone vasopressin, an antidiuretic hormone, allows the kidney to conserve water. However, in diabetes insipidus the hormone is deficient or inactive and the patient will lose massive amounts of water. Symptoms include excessive thirst and frequent urination. If the disease remains untreated, the patient can develop complications.

If water is not readily available, the excessive output of urine will lead to severe dehydration.  Diabetes insipidus can also cause an electrolyte imbalance.

It is a rare condition, affecting approximately 1 in every 25,000 people.

Central Hypothyroidism

Central hypothyroidism is due to a failure of the pituitary gland to release thyroid stimulating hormone (TSH) or thyrotropin releasing hormone (TRH). This is usually caused by a tumor in the area of the pituitary or hypothalamus.

Central hypothyroidism is characterized by weight gain, intolerance to cold, decreased sweating, coarse skin, hair loss, puffy face, hands and feet, slow speech, tiredness, and weakness.

Growth Hormone Deficiency

Growth hormone deficiency (GHD) is a medical condition, caused by problems arising in the pituitary gland, in which the body does not produce enough growth hormone.

Children with growth hormone deficiency have a slow or flat rate of growth, usually less than 2 inches per year. The slow growth may not appear until a child is 2 or 3 years old.

The child will be much shorter than most or all children of the same age and gender.

Children with growth hormone deficiency still have normal body proportions, as well as normal intelligence. However, their face often appears younger than children of the same age. They may also have a chubby body build.

In older children, puberty may come late or may not come at all, depending on the cause.

Postural Orthostatic Tachycardia Syndrome

Postural Orthostatic Tachycardia Syndrome (POTS) is a form of dysautonomia. POTS is a subset of orthostatic intolerance that is associated with the presence of excessive tachycardia on standing.

Many POTS patients experience fatigue, headaches, lightheadedness, heart palpitations, exercise intolerance, nausea, diminished concentration, tremulousness (shaking), syncope (fainting), coldness or pain in the extremeties, chest pain and shortness of breath.

Some patients have fairly mild symptoms and can continue with normal work, school, social and recreational activities. For others, symptoms may be so severe that normal life activities, such as bathing, housework, eating, sitting upright, walking or standing can be significantly limited. Physicians with expertise in treating POTS have compared the functional impairment seen in POTS patients to the impairment seen in chronic obstructive pulmonary disease (COPD) or congestive heart failure.

Motor Dysgraphia

Motor dysgraphia is due to deficient fine motor skills, poor dexterity, poor muscle tone, or unspecified motor clumsiness. Letter formation may be acceptable in very short samples of writing, but this requires extreme effort and an unreasonable amount of time to accomplish, and it cannot be sustained for a significant length of time, as it can cause arthritis-like tensing of the hand. Overall, their written work is poor to illegible even if copied by sight from another document, and drawing is difficult. Oral spelling for these individuals is normal, and their finger tapping speed is below normal. This shows that there are problems within the fine motor skills of these individuals.
