Background: Hashimoto's encephalopathy (HE) is a rare immunological neuropsychiatric disorder characterized by increased antithyroid antibodies and mixed neurological and psychiatric symptoms. HE has been previously discussed as a differential diagnosis for rapid progressive dementia. However, most of these patients suffered from additional neurological symptoms, like ataxia or seizures. Case presentation: Here, we present the case of a 59-year-old female patient suffering rapid onset dementia with salient frontal executive dysfunction...

OBJECTIVE: To assess the relationship between clinical pattern and cerebral glucose metabolism on [18F]fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) in Creutzfeldt-Jakob disease (CJD). METHODS: Predefined clinical signs (ataxia, visual, pyramidal, myoclonus, limb apraxia, limb dystonia, sensory, parkinsonism, and corticobasal syndrome [CBS]) and FDG-PET data were assessed in consecutive CJD patients. Two types of statistical parametric mapping (SPM) analyses, using stringent level of significance p<0...

Behavioral alterations in dogs are not easy to understand and cure. The situation is more difficult when an encephalitis due to Canine Distemper Virus (CDV) and a concomitant olfactory neuroblastoma are present. This case report deals with the story of a 5-year-old Swiss shepherd dog with behavioral changes, seizures, epistaxis and ataxia. Following clinical and laboratory exams, a suspected diagnosis of CDV infection was hypothesized, and a therapy based on Ω-interferon was administered. Every supporting therapy failed and the worsening of the clinical conditions led to the euthanasia of the patient...

Neuropsychiatry is a specialized clinical, academic and scientific discipline with its field located in the borderland territory between neurology and psychiatry. In this article, we approach the theoretical definition of neuropsychiatry, and in order to address the practical aspects of the discipline, we describe the profile of a neuropsychiatric liaison service in the setting of a large hospital for neurological diseases in a middle-income country. An audit of consecutive in-patients requiring neuropsychiatric assessment at the National Institute of Neurology and Neurosurgery of Mexico is reported, comprising a total of 1212 patients...

The Sonic Hedgehog (SHH) pathway is a key signaling pathway orchestrating embryonic development, mainly of the CNS and limbs. In vertebrates, SHH signaling is mediated by the primary cilium, and genetic defects affecting either SHH pathway members or ciliary proteins cause a spectrum of developmental disorders. SUFU is the main negative regulator of the SHH pathway and is essential during development. Indeed, Sufu knock-out is lethal in mice, and recessive pathogenic variants of this gene have never been reported in humans...

Background In large-caliber pial macrofistulae (pMF), the combination of high blood flow velocity and large efferent artery diameter makes control over the endovascular vessel occlusion difficult and may result in the inadvertent venous passage of occlusive devices or embolic agents. Case descriptions Patient 1: A 27-year-old man presented with headache and ataxia. An infratentorial pMF supplied by both superior cerebellar arteries with venous ectasia was found. The first treatment attempt using balloons and coils failed since the position of either device could not be controlled because of a distal diameter of the feeding artery of 8 mm...

Motor impersistence, an inability to sustain a certain position or movement, is a motor-intentional disorder, caused more often by right than left hemisphere lesions. Since the right hemisphere is dominant for mediating motor persistence, callosal lesions that disconnect the left hemisphere from the right may induce impersistence of the right upper and lower limbs. After an undiagnosed left callosal infarction, a 65-year-old right-handed man suddenly developed a transient loss of volitional movement of his left leg...

A 65-year-old man had a transient amnesia for about 3 hours. Similar symptoms appeared three years ago. He did not manifest dementia, cerebellar ataxia and involuntary movements. Peripheral neuropathy was observed by the neurophysiological examinations. Diffusion weighted image showed high intensity signal in the area of the corticomedullary junction of the frontal to parietal lobes and immunohistochemical studies of biopsied skin revealed many intranuclear inclusion bodies. Adult-onset neuronal intranuclear inclusion disease was diagnosed...

Spinocerebellar ataxia type 10 (SCA10) is an autosomal-dominant cerebellar ataxia that is variably accompanied by epilepsy and other neurological disorders. It is caused by an expansion of the ATTCT pentanucleotide repeat in intron 9 of the ATXN10 gene. Until now, SCA10 was almost exclusively found in the American continents, while no cases had been identified in Japan. Here, we report the first case of an SCA10 family from Japan. The clinical manifestations in our cases were cerebellar ataxia accompanied by epilepsy, hyperreflexia and cognitive impairment...

This case highlights a rare possibility of occurrence of chondroblastoma, a bony tumor, at an uncommon location. Extraosseous, soft tissue location of this bony tumor is rare and more so for intracranial intra-axial location. We report a case of an intra-axial frontal lobe lesion, histologically proven to be an extraosseous chondroblastoma. A 23-year-old male presented with a history of headache and vomiting of 1 month duration. Imaging was suggestive of left frontal lobe intra-axial calcified lesion suggestive of oligodendroglioma...

Adrenoleukodystrophy (ALD) is a rare and progressive neurogenetic disease that may manifest disparate symptoms. The present study aims at investigating the role of ataxic variant of ALD (AVALD) in patients with adult-onset cerebellar ataxia, as well as characterizing their clinical features that distinguish AVALD from other cerebellar ataxias. Mutations in the ATP binding cassette subfamily D member 1 gene (ABCD1) were ascertained in 516 unrelated patients with ataxia. The patients were categorized into three groups: molecularly unassigned hereditary ataxia (n = 118), sporadic ataxia with autonomic dysfunctions (n = 296), and sporadic ataxia without autonomic dysfunctions (n = 102)...

The complementation group F of Xeroderma pigmentosum (XP-F) is rare in the Caucasian population, and usually devoid of neurological symptoms. We report two cases, both Caucasian, who exhibited progressive cerebellar ataxia, chorea, a mild subcortical frontal cognitive impairment, and in one case severe polyneuropathy. Brain MRI demonstrated cerebellar (2/2) and cortical (1/2) atrophy. Both patients had only mild sunburn sensitivity and no skin cancer. Mini-exome sequencing approach revealed in ERCC4, two heterozygous mutations, one of which was never described (c...

Friedreich ataxia (FRDA) is an autosomal recessive neurodegenerative disorder with subtle impact on cognition. Inhibitory processes and cognitive flexibility were examined in FRDA by assessing the ability to suppress a predictable verbal response. We administered the Hayling Sentence Completion Test (HSCT), the Trail Making Test, and the Stroop Test to 43 individuals with FRDA and 42 gender- and age-matched control participants. There were no significant group differences in performance on the Stroop or Trail Making Test whereas significant impairment in cognitive flexibility including the ability to predict and inhibit a pre-potent response as measured in the HSCT was evident in individuals with FRDA...

Late-onset progressive cerebellar ataxia is a diagnostic challenge because of a poor correlation between genotype and phenotype, and a broad range of secondary causes that extend beyond the neurological field. We report the case of a 45-year-old woman admitted after 2 years of slowly progressing cerebellar ataxia, dysarthria, and emotional instability. Notably, she was diagnosed with diabetes insipidus at the age of 35. As 'idiopathic cerebellar ataxia' was suspected, diagnostic tests, including genetic testing as well as serum and cerebrospinal fluid analyses, and brain magnetic resonance imaging (MRI) were performed...

Frontotemporal lobar degeneration with transactive response DNA-binding protein 43 (FTLD-TDP) and progressive supranuclear palsy (PSP) are distinct neurodegenerations with different clinical presentations. We report two cases with FTLD-TDP and PSP in comorbidity: a patient with amnestic dementia developing frontal lobe dementia, Parkinsonism and supranuclear gaze palsy and a patient with cerebellar ataxia and nystagmus developing akinesia, rigidity, and subcortical dementia. Neuropathological examination revealed neuronal and glial tau pathology together with ubiquitin, and phospho-TDP-43-immunoreactivities in the hippocampus, striatum, mesencephalon, and frontal and temporal cortices...

OBJECTIVE: Autosomal dominant cerebellar ataxia with deafness and narcolepsy (ADCA-DN) is an emerging syndrome caused by mutations in the C-terminus end of the TS domain of the DNMT1 gene. ADCA-DN is also associated with sensorimotor polyneuropathy, extrapyramidal, and dysautonomic signs, as well as dementia. Little has been reported about the progressive cognitive impairment associated with ADCA-DN. Our objective is to provide a detailed characterization of the cognitive profile of ADCA-DN...

We describe a 27-year-old man with mental retardation, symptomatic epilepsy, myopia, and cerebellar ataxia without spontaneous puberty whose brain magnetic resonance imaging showed hypomyelination. He had child-like facial appearance, with thin facial hair. He had no underarm and pubic hairs, and his penis was small. Laboratory tests showed low levels of luteinizing hormone, follicle-stimulating hormone, and testosterone. Brain MRI showed diffuse hypomyelination, atrophy of the cerebellum and brainstem, and hypoplastic corpus callosum...

Neuronal intranuclear inclusion disease (NIID) is a slowly progressive neurodegenerative disease characterized by eosinophilic hyaline intranuclear inclusions in the central and peripheral nervous system, and also in the visceral organs. NIID has been considered to be a heterogeneous disease because of the highly variable clinical manifestations, and ante-mortem diagnosis has been difficult. However, since we reported the usefulness of skin biopsy for the diagnosis of NIID, the number of NIID diagnoses has increased, in particular adult-onset NIID...
