Hyperammonemia, or high ammonia levels, is a metabolic disturbance characterised by an excess of ammonia in the blood. Severe hyperammonemia is a dangerous condition that may lead to brain injury and death. It may be primary or secondary. Ammonia is a substance that contains nitrogen. It is a product of the catabolism of protein.
Some patients may also have an elevation of ammonia, a toxic chemical, which can affect the nervous system. Argininosuccinic aciduria may become evident in the first few days of life because of high blood ammonia, or later in life presenting with "sparse" or "brittle" hair, developmental delay, and tremors.
Argininemia is an autosomal recessive urea cycle disorder where a deficiency of the enzyme arginase causes a buildup of arginine and ammonia in the blood.Ammonia, which is formed when proteins are broken down in the body, is toxic if levels become too high; the nervous system is especially sensitive to the effects of excess ammonia.
Symptoms of elevated blood ammonia include muscle weakness and fatigue. If left untreated, ammonia can cross the blood brain barrier and affect brain tissues, leading to a spectrum of neuropsychiatric and neurological symptoms including impaired memory, seizure, confusion, delirium, excessive sleepiness, disorientation, brain edema ...
Citrullinemia is an autosomal recessive urea cycle disorder that causes ammonia and other toxic substances to accumulate in the blood. [1] Two forms of citrullinemia have been described, both having different signs and symptoms, and are caused by mutations in different genes. Citrullinemia belongs to a class of genetic diseases called urea ...

A new study found that in about 10% cases of multiple sclerosis, the body begins producing a distinctive set of antibodies against its own proteins years before symptoms emerge. “Multiple ...
In a separate study involving young children ages 2 months through 5 years, glycerol phenylbutyrate resulted in a more evenly distributed urinary output of PAGN over 24 hours and accounted for fewer symptoms from accumulation of phenylacetate. In patients with an extremely high blood ammonia level, rapid treatment with hemodialysis is indicated.
