Presenile Dementia with Bone Cysts

NHD


Presentation

  • Occasionally, the disease presents a different course with the neurologic symptoms preceding the osseous ones.[orpha.net]
  • Such syndromes may be present in as many as 60% of patients with ALS. Conversely, the occurrence of motor neuron dysfunction in patients with clinically pure frontotemporal dementia is increasingly recognized.[books.google.com]
  • At the age of 37 years, she presented a global worsening of neuropsychological functions, which made neuropsychological reassessment impossible.[functionalneurology.com]
  • Most visits are expected to last 2 hour Inclusion/Exclusion Criteria Inclusion Criteria: Patients who meet the following criteria may be included in the study, if they present with all of the following: 1) The subject has signed the IRB approved Informed[hss.edu]

  • This patient’s clinical picture was characterized by a severe progressive dementia associated with radiological evidence of multiple cystic lesions in the metaphyseal regions of bones (5).[functionalneurology.com]
  • This is a rare recessively inherited disease that is characterized by early-onset progressive dementia and bone cysts [ 3 ].[omicsonline.org]

Cognitive Disorder
  • This book begins with an outline of the various cognitive domains and how they can be tested, before covering in depth the cognitive deficits seen not only in prototypical neurodegenerative cognitive disorders (Alzheimer's disease, frontotemporal dementias[books.google.com]

Treatment

  • Management and treatment There is no curative treatment for the disease. Management is supportive. Antiepileptic drugs are prescribed to prevent seizures. A regular orthopedic and neurologic surveillance is recommended.[orpha.net]
  • After a careful review of the symptoms, 6 patients were excluded from surgical treatment and 11 (4 solitary cysts and 7 PLD) were treated by laparoscopic fenestration [9].[wikigenes.org]
  • […] fusion of the ankle plus all hindfoot joints [talonavicular, subtalar, and calcaneocuboid]) or an ankle fusion in combination with any hindfoot fusion. 9) The subject requires subsequent surgery of the concomitant hindfoot within 12 months of study treatment[hss.edu]

Prognosis

  • Prognosis NHD is a progressive disease that is fatal usually during the fifth decade of life. The documents contained in this web site are presented for information purposes only.[orpha.net]
  • Many patients die from fulminant HLH, and the only curative treatment is a hematopoietic stem cell transplant, although this procedure has been associated with a poor prognosis.[mendelian.co]
  • […] macroencephaly. (38-40) Other phenotypes have been reported: oscillopsia, primary ovarian failure, thyroid hormone abnormalities, hypothermia, microcoria, dysautonomia and acute evolution of the disease with death occurring in less than 2 months. (41,42) The prognosis[thefreelibrary.com]

Etiology

  • Etiology NHD is due to mutations in either the TYROBP or TREM2 genes encoding the tyrosine kinase binding adaptor protein and the triggering receptor expressed on myeloid cells 2 respectively.[orpha.net]
  • Conclusions Our study provides strong support for a role of the p.R47H variant in TREM2 in the etiology of FTD and PD.[molecularneurodegeneration.biomedcentral.com]

Epidemiology

  • From Epidemiology 160 cases, mainly in Finland & Japan onset third decade Pathology basal ganglia calcification gliosis white matter demyelination senile plaques neurofibrillary tangles Clinical features: skeletal changes epiphyseal bone cysts , restricted[anvita.info]
  • Summary Epidemiology Over 200 cases have been reported worldwide in the literature, the majority of them being in the Japanese and Finnish population. The prevalence in Finland is estimated between 1/500,000 and 1/1,000,000.[orpha.net]

Pathophysiology

  • Finally, Koga et al. show that while RANK, TREM-2, and OSCAR-mediated signals are necessary, none are sufficient for appropriate osteoclast maturation under physiological conditions. 8 The exact pathophysiology of Nasu-Hakola disease remains unknown.[rndsystems.com]
  • In conclusion, further insights into the pathophysiology of AD and, in general, neurodegenerative diseases are needed. Genetics play a main role in a deep knowledge of them and could lead us new therapeutic approaches.[omicsonline.org]
  • The elucidation of these factors is extremely important and will provide further insights into the pathophysiology of disease and generate novel in vitro and in vivo systems in which to model the disease and screen therapeutics.[molecularneurodegeneration.biomedcentral.com]
