Neuroferritinopathy

Neurodegeneration with Brain Iron Accumulation 3


Presentation

  • We present video case reports of 4 individuals with neuroferritinopathy chosen to illustrate how this disorder can present and subsequently progress clinically.[ncbi.nlm.nih.gov]
  • Clinical description The disease presents typically in the fourth to sixth decades, although cases with symptoms in their late teens have been observed.[orpha.net]
  • Methods : case work up Results : Family 1: A 31 year old female presented with complaints of abnormal movements for last 5 years, starting in her right leg and progressing rapidly to other limbs.[mdsabstracts.org]
Movement Disorder
  • Abstract Neuroferritinopathy is a dominantly inherited movement disorder characterized by deposition of iron and ferritin in the brain, normal or low serum ferritin levels, and highly variable clinical features.[ncbi.nlm.nih.gov]
  • Prognosis The movement disorder is progressive, involving additional limbs in five to ten years and becoming more generalized within 20 years. The documents contained in this web site are presented for information purposes only.[orpha.net]
Hoarseness
  • He had hoarseness of voice with difficulty in swallowing and a recent change in his behaviour. With normal birth history and developmental milestones, there is no consanguineous marriage in the family.[mdsabstracts.org]
  • […] used to make speech This can make a person’s speech difficult to understand in several different ways, including stuttering, slurring, or soft or raspy speech Dysphonia (movement of the vocal cords is forced and strained) Results in a jerky, quivery, hoarse[nbiacure.org]
Behavior Disorder

Hypomimia
  • While 35% developed facial hypomimia and bradykinesia not directly related to their dystonia; only one individual developed a pure rest tremor, and another had tremor present at rest and on intention.[academic.oup.com]
Dystonia
  • Dystonia can affect the face, tongue, arms and legs and onset is also usually asymmetrical. The majority of individuals develop a characteristic orofacial action-specific dystonia related to speech that leads to dysarthrophonia.[orpha.net]
  • A characteristic action-specific facial dystonia was common (65%), and in 63% there was asymmetry throughout the disease course.[ncbi.nlm.nih.gov]
  • From Wikidata Jump to navigation Jump to search Neuroferritinopathy is a late-onset type of neurodegeneration with brain iron accumulation (NBIA; see this term) characterized by progressive chorea or dystonia and subtle cognitive deficits neuroferritinopathy[wikidata.org]
  • The most frequent presentation is with chorea (50%), followed by dystonia (42.5 %) and parkinsonism (7.5%).[eurekaselect.com]
Cognitive Deficit
  • From Wikidata Jump to navigation Jump to search Neuroferritinopathy is a late-onset type of neurodegeneration with brain iron accumulation (NBIA; see this term) characterized by progressive chorea or dystonia and subtle cognitive deficits neuroferritinopathy[wikidata.org]
  • Cognitive deficits, behavioral issues and dysphagia can be a late feature.[orpha.net]
  • Cognitive deficits and behavioral issues become major problems with time. Serum ferritin concentration may be low. Eye movements are well preserved throughout the disease course. Axonal swellings (neuroaxonal spheroids) may be present.[nbiadisorders.org]
  • Global cognitive decline cognitive deficits in all modalities present.[academic.oup.com]
  • These symptoms include chorea, dystonia, and cognitive deficits which worsen with age.This disorder is autosomal dominant and is caused by mutations in the gene encoding the light chain subunit of the ferritin protein.[en.wikipedia.org]
Hyperreflexia
  • […] ferritin Low ferritin level Reduced serum ferritin [ more ] 0012343 Disinhibition 0000734 Dysarthria Difficulty articulating speech 0001260 Dyskinesia Disorder of involuntary muscle movements 0100660 Emotional lability Emotional instability 0000712 Hyperreflexia[rarediseases.info.nih.gov]
  • 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]
  • Spasticity and hyperreflexia as well as retinopathy are often present. The atypical form most commonly presents in the second decade of life and its clinical features are less homogeneous, with less severe extrapyramidal and pyramidal signs.[doi.org]
Cerebellar Sign
  • With the exception of the reported cerebellar signs, the clinical presentation of the patients with the 498InsTC and 646InsC mutations fall within the spectrum we have seen in patients with 460InsA.[academic.oup.com]
Babinski Sign

Workup

  • (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

  • Management and treatment Treatment is of the manifestations of the disease and includes levodopa, tetrabenazine, benzhexol, sulpiride, diazepam, clonezepam and deanol for the movement disorder and botulinum toxin for painful focal dystonia.[orpha.net]
  • The disorder provides a direct link between disordered iron storage and a neurodegenerative disease, opening new avenues for treatment by altering brain iron stores in addition to symptomatic treatments such as local Botulinum toxin and oral anti oxidants[ncbi.nlm.nih.gov]
  • […] and prognosis No disease-specific treatment is available and symptomatic management is recommended 2.[radiopaedia.org]

Prognosis

  • Prognosis The movement disorder is progressive, involving additional limbs in five to ten years and becoming more generalized within 20 years. The documents contained in this web site are presented for information purposes only.[orpha.net]

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

Etiology

  • This chapter summarizes the genetic etiology, pathological, radiological, and clinical data from all published data to date and suggested potential new avenues for therapy.[ncbi.nlm.nih.gov]
  • Non-genetic etiologies are discussed, including medications, structural lesions, psychogenic causes, and metabolic abnormalities. This book describes in detail the latest clinical and etiological information regarding the causes of chorea.[books.google.com]
  • Etiology Neuroferritinopathy is caused by mutations in the ferritin light chain ( FTL ) gene (19q13.3-q13.4) and is inherited in an autosomal dominant manner with high penetrance.[orpha.net]

Epidemiology

  • Summary Epidemiology Prevalence of neuroferritinopathy is unknown. To date fewer than 50 cases have been reported.[orpha.net]
  • Epidemiology Map of England Neuroferritinopathy was first discovered in 2001, with its first case being reported in Cumbria from Northern England.[dict.eudic.net]
  • […] affecting movement (dystonia) have also been treated with L-Dopa , orphenadrine , benzhexol , sulpiride , diazepam , clonazepam , and deanol . [ 4 ] Parkinsonian symptoms were not decreased by L-Dopa . [ 1 ] Iron supplements should be avoided. [ 4 ] Epidemiology[research.omicsgroup.org]
  • The 460InsA insertion was not present in the 100 anonymized samples from the Cumbrian population collected as part of a resource for genetic epidemiology.[academic.oup.com]
  • They show variable incidence, and, from an epidemiological point of view, it is also important to note that these diseases are extremely rare and some are generally confined to specific populations ( Dusek and Schneider, 2012, 2013 ). TABLE 1.[doi.org]

Pathophysiology

  • Management strategies, pathophysiology, and associated medical and psychiatric problems associated with chorea are also addressed.[books.google.com]
  • The relevant articles were reviewed with a focus on the pathophysiology, clinical presentation, differential diagnoses, and management of NF.[academiccommons.columbia.edu]
  • This raises the possibility that mitochondrial dysfunction may play an important part in the pathophysiology of neuroferritinopathy.[jmg.bmj.com]

Prevention

  • Prevention of secondary complications: Adequate caloric intake; physiotherapy to maintain mobility and prevent contractures. Agents/circumstances to avoid: Iron supplements are not recommended. NOTE: The above information is for processing purpose.[medigoo.com]
  • Long-term surveillance for neuroferritinopathy can include: Regular assessment of nutrition and caloric intake Physiotherapy to maintain mobility and prevent contractures (permanent tightening of a muscle or joint).[nbiacure.org]
  • Ferritin stores essential iron inside cells and prevents the iron causing damage. The error leads to large amounts of iron and ferritin collecting in the cells and causing problems with body movements.[news.bbc.co.uk]
