While portions of the dieease pallidus and pars reticulata of the substantia nigra SN have high iron content in healthy individuals, individuals with HSD have excess amounts of iron deposited in these areas. Computed tomography CT scanning CT imaging is not very helpful in the diagnosis of HSD but may exhibit hypo-density in the basal ganglia and some atrophy of the brain.
Lyon G, et al. However, these findings were not confirmed in adult patients. A case of Hallervorden-spatz disease: J Child Neurol ; Hypertonia is usually a combination of rigidity and spasticity and may be difficult to treat.
Iron accumulation in syndromes of neurodegeneration with sptaz iron accumulation 1 and 2: You may also experience involuntary muscle contractions that cause abnormal posture or slow, recurring movements.
Dysarthria may respond to medications used for rigidity and spasticity. Because of severe dystonia in limbs and tongue muscles, he was unable to eat easily as you can see in movie.
Others have a slower progression or can plateau for long periods of time and continue to function into the third decade of life.

This disorder primarily affects people of Portuguese heritage. Case 4 A year-old man presented with dysphagia, motor difficulties, and speech problems.
Hallervorden-Spatz disease HSD is also known as neurodegeneration with brain iron accumulation or pantothenate kinase-associated neurodegeneration. If an individual receives one normal gene and one gene for the disease, the person will be a carrier for the disease but usually will not show symptoms.
Indian Journal of Pathology and Microbiology. Molecular genetic testing for the full gene sequence of the PANK2 gene is the gold standard way to make this diagnosis. Their discovery was brought about by a diagnosis of a family of 12 in which five sisters exhibited progressively increasing dementia and dysarthria. However, the exact role of iron in the etiology of this disease remains unknown. Here we present four HSD cases with different clinical pictures. We describe hallervrden child with pathologically proven Hallervorden Spatz disease.
N Engl J Med ; This gene encodes the enzyme pantothenate kinase, and mutations in the gene lead to an inborn error of vitamin B5 pantothenate metabolism. Additional symptoms often develop including progressive cognitive impairment, muscle weakness, seizures and behavioral or personality changes.
Because rare disorders like PKAN often go unrecognized, these disorders may be under-diagnosed or misdiagnosed, spqtz it difficult to determine the accuracy of these estimates. Unusual phenotypes, novel PANK2 mutations, and undetermined genetic forms.

Because of the limited ability to protect themselves during falls, children may have repeated injury to the face and chin. Some people have been diagnosed in infancy or adulthood, and some of those affected have characteristics that are between the two categories.
These early agents were proven ineffective and can cause anemia. Indian Journal of Radiology and Imaging. Medications such as methscopolamine bromide can be attempted for excessive drooling.
Etiology Hallervorden Spatz disease was first described in by two German physicians, Hallervorden and Spatz, as a form of familial brain degeneration characterized by cerebral iron deposition and hence the nallervorden so.
Nil Conflict of Interest: If dopaminergic agents are not effective against dystonia, anticholinergics can be used, but they offer only transient relief.
