Most neurodegeneration with brain iron accumulation (NBIA) disorders can be distinguished by identifying characteristic changes on magnetic resonance imaging (MRI) in combination with clinical findings. However, a significant number of patients with an NBIA disorder confirmed by genetic testing have MRI features that are atypical for their specific disease. The appearance of specific MRI patterns depends on the stage of the disease and the patient's age at evaluation. MRI interpretation can be challenging because of heterogeneously acquired MRI datasets, individual interpreter bias, and lack of quantitative data. Therefore, optimal acquisition and interpretation of MRI data are needed to better define MRI phenotypes in NBIA disorders. The stepwise approach outlined here may help to identify NBIA disorders and delineate the natural course of MRI-identified changes.

Pathology and treatment methods in pantothenate kinase-associated neurodegeneration.

Independent Public Health Care Institution named after doctor Kazimierz Hołoga, Nowy Tomyśl, Poland.

Purpose: The purpose of this review is to present current scientific reports on the pathophysiology, diagnosis and treatment of pantothenate kinase-associated neurodegeneration (PKAN).

Views: The condition is caused by a mutation in the PANK2 gene, which results in iron accumulation in the brain and changes in the functioning of biochemical pathways dependent on coenzyme A. There are two clinical types of PKAN, which differ in the time of onset of symptoms and speed of disease progression.

Article Synopsis
  • - Neurodegeneration with brain iron accumulation 5 (NBIA5) is caused by mutations in the WDR45 gene and is inherited in an X-linked fashion.
  • - The study presents three Iranian patients with distinct mutations in the WDR45 gene, identified through whole-exome sequencing, including c.697 C>T, c.657_658del, and c.1004_1005del.
  • - Hypothyroidism was found in two of the cases, and overall, the clinical features were consistent with existing literature, highlighting the genetic diversity of this disorder in the Iranian population.

Article Synopsis
  • * The diagnosis of PKAN relies on clinical observations, a specific brain MRI finding called the "eye of the tiger," and genetic testing for mutations in the pantothenate kinase 2 (PANK2) gene, which plays a crucial role in coenzyme A (CoA) production.
  • * Research shows that combining multitarget supplements (like pantothenate, pantethine, omega-3, and vitamin E) with standard

Neurodegeneration with brain iron accumulation (NBIA) is a genetic disorder characterized by iron accumulation in the basal ganglia. Patients may develop behavioral abnormalities, dementia, movement disorders, and neuropsychiatric symptoms such as emotional lability, depression, anxiety, hallucinations, impulsivity, obsessions, and hyperactivity. In this case, a 46-year-old male patient with a C19orf12 mutation experienced depressive complaints before movement disorders, followed by cognitive deficits and psychotic symptoms as the disease progressed.

Neurodegeneration with brain iron accumulation (NBIA) is a group of rare neurodegenerative diseases characterized by iron accumulation in the brain. Mitochondrial membrane protein-associated neurodegeneration (MPAN) is a subtype of NBIA caused by an autosomal recessive mutation in the C19orf12 gene. In this work, we generated and characterized four lines of human induced pluripotent stem cell (hiPSCs) derived from dermal fibroblasts of patients carrying homozygous mutation c.
