A neuromiotonia, também conhecida como síndrome de Isaacs, é uma síndrome de hiperexcitabilidade dos nervos periféricos (HPN) que se apresenta como atividade motora contínua. Os achados clínicos incluem cãibras, fasciculações e mioquimia. O eletrodiagnóstico desempenha um papel fundamental no diagnóstico, demonstrando pós-descargas nos estudos de condução nervosa e potenciais de fasciculação, descargas mioquímicas, descargas neuromiotónicas e outros tipos de atividade espontânea anormal no exame com agulha. A etiopatogenia envolve a interação de factores genéticos, auto-imunes e paraneoplásicos, o que exige uma avaliação abrangente das causas subjacentes. O tratamento inicial é sintomático, mas a imunoterapia é frequentemente necessária e pode ser eficaz.

Neuropathy, hereditary motor and sensory, 6B, with optic atrophy
An autosomal recessive neurologic disorder characterized by early-onset optic atrophy, progressive visual loss, and peripheral sensorimotor neuropathy manifesting as axonal Charcot-Marie-Tooth disease, with variable age at onset and severity. Charcot-Marie-Tooth disease is a disorder of the peripheral nervous system, characterized by progressive weakness and atrophy, initially of the peroneal muscles and later of the distal muscles of the arms. It is classified in two main groups on the basis of electrophysiologic properties and histopathology: primary peripheral demyelinating neuropathies and primary peripheral axonal neuropathies. Peripheral axonal neuropathies are characterized by signs of axonal regeneration in the absence of obvious myelin alterations, and normal or slightly reduced nerve conduction velocities.

Subclinical involvement of central nervous system structures other than motor or sensory tracts in SPG3A and SPG4 patients.
Hereditary spastic paraplegias (HSPs) comprise a heterogeneous group of rare, neurodegenerative disorders. The most prominent HSP features: spastic paraparesis, mild somatosensory deficits and bladder dysfunction may be accompanied by additional symptoms i.e.: neuropathy, epilepsy, dementia. We aimed to determine subclinical involvement of nonmotor or sensory brain structures in hereditary spastic paraplegias type 3 A (SPG3A) and type 4 (SPG4). Visual evoked potentials (VEPs), brainstem evoked potentials (BAEPs) and electroencephalography (EEG) were performed in 28 SPG4 and 9 SPG3A patients. Disease severity was evaluated with Spastic Paraplegia Rating Scale. The EEG examination revealed abnormalities in 9 SPG4 patients (35%), while it was intact in SPG3A individuals. VEPs indicated mild abnormalities in 38% SPG3A patients: 127.3±7.8ms and 48% SPG4: 122.2±6.4ms. SPG4 patients with DNA microrearrangements in the SPAST gene had statistically significantly longer VEPs latencies (95%CI, 2.78–10.10) and lower amplitudes (95%CI, -5.65 – (-1.45)) than those with single nucleotide variants. BAEPs were distracted accidentally. It appears that visual tracts, which involve shorter axons than in motor-sensory pathways, are also involved in neurodegenerative processes in SPG3A and SPG4. Additionally, in SPG4 abnormal oscillations of neurons indicated by EEG may probably result from impaired axonal transport. The online version contains supplementary material available at 10.1186/s12883-025-04624-4. Our study shows that SPG3A and SPG4 phenotypes are often combined with subclinical nonmotor or sensory brain dysfunctions.

Charcot-Marie-Tooth disease type 1E: clinical natural history and molecular impact of PMP22 variants.
Charcot-Marie-Tooth disease type 1E (CMT1E) is a rare, autosomal dominant peripheral neuropathy caused by missense variants, deletions, and truncations within the peripheral myelin protein-22 (PMP22) gene. CMT1E phenotypes vary depending on the specific variant, ranging from mild to severe, and there is little natural history and phenotypic progression data on individuals with CMT1E. Patients with CMT1E were evaluated during initial and follow-up visits at sites within the Inherited Neuropathy Consortium. Clinical characteristics were obtained from history, neurological exams, and nerve conduction studies. Clinical outcome measures were used to quantify baseline and longitudinal changes, including the Rasch-modified CMT Examination Score version 2 (CMTESv2-R) and the CMT Pediatric Scale (CMTPedS). The trafficking of PMP22 variants in transfected cells was correlated to disease severity. Twenty-four presumed disease-causing PMP22 variants were identified in 50 individuals from 35 families, including 19 missense variants, three in-frame deletions, and two truncations. Twenty-nine patients presented with delayed walking during childhood. At their baseline evaluation, the mean CMTESv2-R in 46 patients was 16 ± 7.72 (out of 32), and the mean CMTPedS from 17 patients was 28 ± 6.35 (out of 44). Six individuals presented with hearing loss, eleven with scoliosis, three with hip dysplasia, and one with both scoliosis and hip dysplasia. Twenty variants were localized within transmembrane domains; 31 of 35 individuals with these variants had moderate to severe phenotypes. Three variants were found in the extracellular domain and were associated with milder phenotypes. Reduced expression of PMP22 at the cell surface, and the location of missense variants within the transmembrane domain correlated with disease severity. Pathogenic PMP22 variants located within the transmembrane regions usually cause a moderate to severe clinical phenotype, beginning in early childhood, and have impaired trafficking to the plasma membrane.
Metabolic signatures in sciatic nerve of PMP22 transgenic rats provide insights into the pathogenesis of charcot-marie-tooth disease type 1 A.
Charcot-Marie-Tooth Type 1 A (CMT1A) is a hereditary neuropathy caused by a duplication of the peripheral myelin protein 22 (PMP22) gene. Emerging evidence suggests that lipid metabolism plays a central role in CMT1A pathology. This study investigated metabolic profiles in sciatic nerve tissue and plasma of PMP22 transgenic (TG) and wild-type (WT) rats at 2, 4, and 6 months of age. Utilizing targeted metabolomics, more than 600 metabolites covering central metabolic pathways and major lipid classes were analyzed, revealing distinct age-dependent changes in metabolic pathways. Alterations that emerged early and became increasingly pronounced with age were observed in sphingolipids and glycerophospholipids, while changes in other metabolic pathways, such as amino acids, storage lipids, bile acids, and nucleotide metabolism, were age-specific. Notably, in contrast to these age-dependent adaptive changes, three lipid signatures were identified that remained stable from the earliest age examined. These include: (1) an elevated ratio of hydroxylated to non-hydroxylated sphingolipids, (2) a reduced ratio of monounsaturated-containing to saturated fatty acid containing phosphatidylcholines, and (3) a decreased ratio of hexosylceramides to ceramides. Imaging mass spectrometry analyses confirmed disruptions in sphingolipid metabolism. These findings suggest a key regulatory role of PMP22 in lipid metabolism, as demonstrated by the early stabilization of specific lipid signatures compared to other metabolic changes that occurred in an age-dependent and adaptive manner. These observations provide valuable insights into the pathogenic mechanisms underlying CMT1A.
Fampridine in Hereditary Spastic Paraplegia Type 4 With SPAST Variant c.683-2A>C: A Case Report.
BACKGROUND The most frequently mutated gene in hereditary spastic paraplegia (HSP) is SPAST. Only symptomatic treatment is available for this disease. Fampridine has been successfully used to treat gait disturbances in some patients with HSP. A positive effect of fampridine has not been previously reported in HSP4 caused by the c.683-2A>C variant in the SPAST gene. CASE REPORT We report the case of a 63-year-old woman with hypogeusia and hyposmia for several years, pollakiuria, gait disturbances, reduced walking speed, occasional dysphagia, constipation and delayed defecation, occasional memory problems, right-sided hearing loss, and exercise-induced myalgia and muscle cramps. Genetic testing revealed the c.683-2A>C variant in SPAST. Her 69-year-old sister also had pollakiuria since her youth, and since the age of 50 had frequent stumbling, unsteadiness, spasticity, and positional vertigo. At age 62, our patient began taking fampridine (4-aminopyridine) and has since experienced significant relief. Fampridine led to an improvement in spasticity, gait disorders, and walking speed, as documented by the 6-meter walk test, spastic paraplegia rating scale, and multidimensional self-esteem scale. CONCLUSIONS This case shows that HSP4 can progress slowly over a period of 7 years and can present with typical phenotypic characteristics of the disease as it progresses. The rate of progression can vary among affected family members, and people with HSP4 can still work even in old age and do not necessarily need antispastic drugs. This case also provides preliminary evidence that fampridine may be a viable symptomatic treatment option for patients with HSP4, including those with the mutation c.683-2A>C. It justifies further prospective, controlled studies in a larger SPAST-HSP population.
Comprehensive Characterization of Spastic Paraplegia in Korean Patients: A Single-Center Experience over Two Decades.
Hereditary spastic paraplegia (HSP) refers to a group of genetic neurodegenerative diseases marked by gradually worsening spasticity and hyperreflexia in the lower extremities. This study aimed to describe the clinical and genetic characteristics of Korean patients with spastic paraplegia. We retrospectively reviewed medical records of 69 patients with spastic paraplegia from 54 unrelated families between 2002 and 2024. Genetic, clinical, electrophysiological, and radiological features were comprehensively analyzed. Causative genes were identified in 34 (63%) of 54 unrelated families; SPAST, detected in 26 families, was the most prevalent. Seven novel pathogenic variants were identified. Clinically, the median age of symptom onset was 25 years [14.0-37.0]. Out of 69 patients with spastic paraplegia, 51 (74%) presented with the pure form of spastic paraplegia, which included all patients with SPG4. Spastic gait was a universal feature in all patients. Urinary dysfunction was present in 42 (61%) patients. Additional neurologic manifestations included peripheral neuropathy 9 (13%), cognitive impairment 5 (7%), upper limb weakness 4 (6%), dysarthria 4 (6%), dysphagia 3 (4%), ataxia 3 (4%), and scoliosis 1 (3%). Brain MRI findings demonstrated a thin corpus callosum in two patients with SPG11; all patients with SPG4 had normal findings. Spine MRI revealed spinal cord atrophy in 16 (27%) patients, including 6 (21%) patients with SPG4. The study comprehensively reviewed genetic and clinical spectra of spastic paraplegia in Korean patients, emphasizing the predominance of SPAST as the causative gene and underscoring the genetic and phenotypic heterogeneity of spastic paraplegia.
