Julius Hallervorden and Hugo Spatz with their study of a family of 12 in which five sisters exhibited progressively increasing dementia and poor articulation and slurred speech dysarthria. The frequency of PKAN is estimated to be one to three per million individuals worldwide. Treatment is aimed at reducing the amount of copper that has accumulated in the body and maintaining normal copper levels thereafter.
Neurological examination revealed sever slurred speech; sever tongue dystonia, mild bilateral rigidity on lower limbs, hyperreflexia, and auto babinski.
Being a progressive, degenerative nerve illness, PKAN leads to early immobility and often death by early adulthood. Because of the limited ability to protect themselves during falls, children may have repeated injury to the face and chin. All the abnormal movements subsided during sleep. In addition to rigidity, dystonia, and chorea, patients may experience spasticity, brisk reflexes, and extensor plantar responses.
The anticholinergic agent benztropine helps rigidity and tremor. The following three disorders may present with early clinical symptoms that are similar to those seen in classic PKAN:.
Phosphopantothenate has been shown to treat PKAN in a human, and also in a mouse model of the disease.

Individuals with PKAN have abnormal accumulation of iron in certain areas of the brain. In addition, some patients with Kufor-Rakeb syndromealso known as Parkinson disease-9 PARK9have iron deposition in the basal ganglia. Such hallervordden result in an autosomal recessive inborn error of coenzyme A metabolism called PANK2— associated neurodegeneration.
