Mental alertness and intellectual capacities are not affected. Disruption of this enzyme affects energy and lipid metabolism and may lead to accumulation of potentially harmful compounds in the brain, including iron.

Spasticity and muscle rigidity usually begin in the legs and later develop in the arms. Newer forms of chelation therapy, including the drug deferiprone, are being studied to determine if they could be beneficial see www.

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. Additional abnormalities may include relatively slow, involuntary, continual writhing movements athetosis or chorea, a related condition characterized by irregular, rapid, jerky movements.

The disrase of PKAN is made based upon a detailed patient history, a thorough clinical evaluation, and a variety of specialized tests. Etiology Hallervorden Spatz disease was first diseaae in by two German physicians, Hallervorden and Spatz, as a form of familial brain degeneration characterized by cerebral iron deposition and hence the name so.

Developmental screening and assessment for physical, occupational and speech therapy may also be done. Atypical individuals often retain a high level of function into later adulthood and some are known to be living in their sixties to seventies.
