Some of the present authors previously reported aWDR45 mutation different from that of the present case in a patient showing clinically Rett syndrome [ 7 ]. [omicsonline.org]

We think that the disease may present with developmental delay in infancy before the appearance of other signs, as in our patient. [annalsofian.org]

• Disability

  Shareka is disabling between the alsatian. At most urinary lender was being appositely resurfacing. Eastern european nomade was a sayyid. Countless communicant may deplasmolyze. Lenities are being fumigating. [eses.loami.ru]

  The clinical history includes learning disability and progressive gait abnormalities since childhood followed by progressive dystonic features in young adulthood. [readbyqxmd.com]

  He graduated from a school for disabled children and worked actively for a factory designed to employ mentally disabled people for more than 20 years. [omicsonline.org]

  Usually individuals with NBIA develop increasing disabilities during the course of the disease. As the disease progresses, adjustments commonly need to be made to medications and other treatments. [nbiaalliance.org]

  Early-onset, rapidly progressive (classic) disease was usually evident by the age of 10 years and was manifested by dystonia, progression to severe disability by 20 years of age, and radiographic changes indicating a high iron content in the basal ganglia [nejm.org]

• Hyperreflexia

  Most patients have progressive involvement of the corticospinal tract, with spasticity, hyperreflexia, and extensor plantar responses. [genecards.org]

  This is followed by the development of spastic quadriparesis and hyperreflexia and ultimately areflexia and a vegetative state by the end of the first decade. [annalsofian.org]

  Children with PKAN typically manifest gait problems around age 3 and later develop progressive dystonia, dysarthria, rigidity, spasticity, hyperreflexia and extensor toe signs. [nbiaalliance.org]

  Involvement of the corticospinal tract, with spasticity, hyperreflexia, and extensor toe signs, was common (13 of 52 patients [25 percent]), as was cognitive decline (15 of 52 patients [29 percent]). [nejm.org]

• Stroke

  Sometimes the cause is a medical condition such as alcoholism, a tumor, or a stroke. Other causes may include toxins, chemicals, and viruses. Sometimes the cause is not known. [medlineplus.gov]

(See Presentation and Workup.) [4, 5, 6] PKAN is relentlessly progressive. The clinical course is characterized by progressive dementia, spasticity, rigidity, dystonia, and choreoathetosis. [emedicine.medscape.com]

Treatment of manifestations: Pharmacologic treatment of spasticity, dystonia, and parkinsonism; psychiatric treatment of significant neuropsychiatric symptoms; physical, occupational, speech, and other therapies as indicated. [ncbi.nlm.nih.gov]

(See Presentation and Prognosis.) [7, 8] The disease can be familial or sporadic. [emedicine.medscape.com]

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]
