At 14 years of age, she was noted to have limited elbow extension, mild hirsutism and tapering of her fingers ( Figure 1 ; Supplementary Video ). A brain MRI at that time revealed iron deposition in the basal ganglia.[nature.com]

She developed abnormaleyemovements and auditory inattention. There were no seizures. There was no family history of neurological disease. On examination, her head circumference was normal and she did not have any dysmorphic features.[annalsofian.org]
Symptoms include juvenile parkinsonism, dementia, abnormaleyemovements and involuntary jerking of facial and finger muscles. Neuroferritinopathy is the only genetically dominant form of NBIA identified so far.[nbiaalliance.org]

Seizures are frequently multiform and include focal seizures with impaired consciousness, epileptic spasms [Hogarth, personal communication], and generalizedseizures, including absence, atonic, myoclonic, and tonic-clonic [ Hayflick et al 2013 ].[ncbi.nlm.nih.gov]
Most children are described as clumsy with an ataxic gait — unsteady, staggering movements while walking. Generally, the individuals are healthy, but they may exhibit other problems. Seizures are common, as are sleep disorders.[nbiadisorders.org]
Children are typically clumsy and have a broad-based or ataxic gait. Some never learn to walk; others who achieve walking eventually become non-ambulatory. Some have mild spasticity that generally does not require treatment.[ncbi.nlm.nih.gov]
Other clinical features include: spastic cerebral palsy spasticquadriplegia Iron accumulation in the brain specifically in globus pallidus and substantia nigra. This disorder is thought to be genetically determined with defective iron metabolism.[radiopaedia.org]
Its clinical course is described as biphasic with an initial presentation during childhood, as spasticquadriplegia or static encephalopathy with early developmental delay with or without seizures, followed by dementia in adulthood and the development[nature.com]

Her infantile spasms and hypsarrhythmia disappeared promptly by adrenocorticotropic hormone therapy (CORTROSYN Z, 0.0125mg/kg/day daily for 2weeks intramuscularly), though the administration of pyridoxal phosphate and valproic acid had poor efficacy.[readbyqxmd.com]
Early referral to a neurology epilepsy sub-specialist is recommended if hypsarrhythmia or another aggressive electrographic pattern is found on EEG.[ncbi.nlm.nih.gov]
Numerous tau-positive neurofibrillary tangles were seen in several regions; no beta-amyloidplaques or Lewy bodies were observed [ Hayflick et al 2013 ].[ncbi.nlm.nih.gov]

The specific course and prognosis should implicate restrained psychopharmacological interventions. The clinical picture and imaging hallmarks are often highly suggestive and should lead to suspect this specific disorder.[ncbi.nlm.nih.gov]
Early diagnosis of BPAN is of utmost importance, providing families with a direction for possible management and prognosis and preventing further unnecessary diagnostic testing.[pediatrics.aappublications.org]

Etiology The exact etiology of PKAN is not known. One proposed hypothesis is that abnormal peroxidation of lipofuscin to neuromelanin and deficient cysteine dioxygenase lead to abnormal iron accumulation in the brain.[emedicine.medscape.com]
