What causes iron deposits in the brain?

What causes iron deposits in the brain?

Mutations of the CP gene result in deficient levels of functional ceruloplasmin, which ultimately results in the accumulation of iron in the brain and other organs of the body. Iron accumulation damages the tissue of affected organs causing the characteristic symptoms of aceruloplasminemia.

What causes NBIA disease?

PKAN, or Pantothenic Kinase-Associated Neurodegeneration, is caused by mutations in the PANK2 gene. This is the most common form of NBIA, making up approximately 30% of the NBIA population. This gene provides the instruction for making an enzyme called pantothenate kinase.

Is NBIA curable?

There is no cure for NBIA, nor is there a standard course of treatment. Treatment is symptomatic and supportive, and may include physical or occupational therapy, exercise physiology, and/or speech pathology.

How is NBIA diagnosed?

The diagnosis is usually suspected with findings of brain iron accumulation on MRI. However, both clinical findings and molecular genetic testing establish the diagnosis of specific subtypes. Our panel is the most comprehensive clinical NBIA testing panel currently available.

What is hallervorden Spatz syndrome?

Hallervorden–Spatz syndrome is an autosomal recessive disorder characterized by dystonia, parkinsonism, and iron accumulation in the brain. Many patients with this disease have mutations in the gene encoding pantothenate kinase 2 (PANK2); these patients are said to have pantothenate kinase–associated neurodegeneration.

Can haemochromatosis affect the brain?

Hereditary hemochromatosis (HH), characterized by systemic iron loading, usually does not involve the CNS, and only sporadic cases of neurological abnormalities or brain-MRI T2/T2*GRE-hypointensity have been reported.

What is neurodegeneration in the brain?

Neurodegenerative disorders are illnesses that involve the death of certain parts of the brain. They are, by far, some of the toughest diseases to cure with debilitating outcomes. Parkinson’s and Huntington’s Disease are among the most severe and common movement disorders.

Can iron be removed from the brain?

At this time there was also evidence for a decrease in substantia nigra iron content, which took up to nine months in the Davos study. Clearly, this indicates that there is a selective removal of iron from different brain regions.

Can iron overload cause neurological symptoms?

Brain iron accumulation makes ACP unique among systemic iron overload syndromes, e.g., various types of genetic hemochromatosis. The main clinical features of fully expressed ACP include diabetes, retinopathy, liver disease, and progressive neurological symptoms reflecting iron deposition in target organs.

Can iron deposit in the brain?

Iron gradually deposits in specific regions of the normal brain and particularly the basal ganglia. Histologically, the structures richest in iron are the globus pallidus and substantia nigra, followed by the red nucleus, putamen, caudate nucleus, dentate nucleus and the subthalamic nucleus.

What is neuro Neuroacanthocytosis?

Neuroacanthocytosis is a general term for a group of rare progressive disorders characterized by the association of misshapen, spiny red blood cells (acanthocytosis) and neurological abnormalities, especially movement disorders.

What is PKAN disease?

Summary. Pantothenate kinase-associated neurodegeneration (PKAN), formerly called Hallervorden-Spatz syndrome, is a rare, inherited neurological movement disorder characterized by the progressive degeneration of specific regions in the central nervous system (neurodegenerative disorder).
