Pathologic examination hallerrvorden characteristic rust-brown discoloration of the globus pallidus and substantia nigra pars reticularis due to iron deposition and a reduction in the size of the caudate nuclei, substantia nigra, and tegmentum as well as generalized atrophy of the brain.
Case 4 A year-old man presented with dysphagia, motor difficulties, and speech problems. PKAN is inherited as an autosomal recessive genetic condition and is described as being classical or atypical. Seizures — Have been described. The Johns Hopkins University. Pantothenate kinase-associated neurodegeneration PKANalso known as neurodegeneration with brain iron accumulation 1 NBIA1also called Hallervorden—Spatz syndrome   is a degenerative disease of the brain that can lead to parkinsonismdystoniadementiaand ultimately death.
Journal of Association of Physicians of India. She had severe asymptomatic twisting tremor in hands. Neurological examination revealed hyper-extension in neck muscles and because apatz that she was unable to look downward.
Case 2 A year-old girl was relatively asymptomatic until age of 14 years when she started spztz on toes and unsteady gait. Clinical trials are needed to investigate the effectiveness of this treatment. Specific forms of dystonia that may occur in association with PKAN include blepharospasm and torticollis.

Certain rare metabolic disorders can also present with symptoms similar to PKAN, including beta-hexosaminidase deficiency disorders halletvorden as Tay-Sachs disease and Sandhoff disease. Hellervorden Spatz Disease or PKAN is characterized by progressive dystonia, a motor disorder of extrapyramidal type with gait difficulty.
The central T2 relatively hyperintense spot or line within the globi pallidi is due to gliosis and vacuolisation. Swaiman KF, Hallervorden-spatz syndrome and brain iron metabolism.

Neurodegeneration in PKAN is accompanied by an excess of iron that progressively builds up in the brain. Lab data were negative for Wilson serology. Click here to view as Video 3 Click here to view. The basal ganglia is a collection of structures deep within the base of the brain that assist in regulating movements.
Hallervorden-Spatz disease HSD is a rare disorder characterized by progressive extrapyramidal dysfunction and dementia. Non-ketotic hyperglycemic chorea-hemiballismus mimicking basal ganglia hemorrhage. Newer forms of chelation therapy, including the drug deferiprone, are being studied to determine if they could be beneficial see www.
Visual impairment – Consequence of optic atrophy or retinal degeneration; can be the presenting symptom of the disease, although this is rare. HSD is a hallervordden disease. Pathological examination of the brain showed iron deposition in bilateral globus pallidi, spongiform change and neuron axonal degeneration spheroids. The known mutation in Agarwal community is pathogenic mutation 1c. The parents of an afflicted child must both be heterozygous carriers for the disease and therefore must carry one mutant allele.
Life-threatening complications may result from pneumonia or other infections, injuries related to falls, or other associated developments. Dopamine agonists and anticholinergics may help to reduce rigidity. These individuals face significant speech deficits as well as psychiatric and behavioral disturbances. General Discussion Summary Pantothenate kinase-associated neurodegeneration PKANformerly 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.
Spaatz genes reveal major role for iron in neurodegeneration.
Pantothenate kinase associated neurodegeneration PKAN presenting as a seizure disorder. Why It Happens and How to Sparz It Since the introduction of the first birth control pill inwomen have come to rely on the pill as an effective way to prevent pregnancy.
Because rare disorders like PKAN often go unrecognized, these disorders may be under-diagnosed or misdiagnosed, making it difficult to determine the accuracy of these estimates.
Unintentional, jerky muscle movements are another symptom. Evidence of extrapyramidal dysfunction, including 1 or more of the following: As the condition progresses, paralysis may develop that is associated with increased muscle stiffness rigidity and restricted movements spastic paralysis. In lower limbs, tremor was more severe on the left side. Neurodegeneration with Brain Iron Accumulation.
Case Rep Neurol Med. However, whether the deposition of iron in basal ganglia in HSD is the cause or consequence of neuronal loss and gliosis is not clear. Bag Journal of Neuroimaging.

Pallidal stimulation in siblings with pantothenate kinase-associated neurodegeneration: Loss of this peripheral vision may contribute to the more frequent falls and gait disturbances in the early stages.
Obligate features of HSD include the diseaxe Levels of copper, ceruloplasmin, lipids, amino acids, and acanthocytes typically are measured in the blood to exclude other conditions.
