Acute hepatic porphyrias for the neurologist: current concepts and perspectives

ABSTRACT Background: Acute hepatic porphyrias represent an expanding group of complex inherited metabolic disorders due to inborn errors of metabolism involving heme biosynthesis. Objective: We aimed to review the main clinical and therapeutic aspects associated with acute hepatic porphyrias. Methods: The authors provided a wide non-systematic review of current concepts and recently acquired knowledge about acu...

Adult-onset non-5q proximal spinal muscular atrophy: a comprehensive review

Abstract Background: Adult-onset spinal muscular atrophy (SMA) represents an expanding group of inherited neurodegenerative disorders in clinical practice. Objective: This review aims to synthesize the main clinical, genetic, radiological, biochemical, and neurophysiological aspects related to the classical and recently described forms of proximal SMA. Methods: The authors performed a non-systematic critical re...

Immunosuppressors and immunomodulators in Neurology - Part I: a guide for manag...

ABSTRACT For patients with autoimmune diseases, the risks and benefits of immunosuppressive or immunomodulatory treatment are a matter of continual concern. Knowledge of the follow-up routine for each drug is crucial, in order to attain better outcomes and avoid new disease activity or occurrence of adverse effects. To achieve control of autoimmune diseases, immunosuppressive and immunomodulatory drugs act on d...

A complex association of cardiomyopathy, mild dysmorphisms and leukoencephalopathy

Clinical and epidemiological profiles of non-traumatic myelopathies

ABSTRACT Non-traumatic myelopathies represent a heterogeneous group of neurological conditions. Few studies report clinical and epidemiological profiles regarding the experience of referral services. Objective To describe clinical characteristics of a non-traumatic myelopathy cohort. Method Epidemiological, clinical, and radiological variables from 166 charts of patients assisted between 2001 and 2012 were comp...

Clinical and genetic basis of congenital myasthenic syndromes

ABSTRACT Neuromuscular junction disorders represent a wide group of neurological diseases characterized by weakness, fatigability and variable degrees of appendicular, ocular and bulbar musculature involvement. Its main group of disorders includes autoimmune conditions, such as autoimmune acquired myasthenia gravis and Lambert-Eaton syndrome. However, an important group of diseases include congenital myasthenic...

Far beyond the motor neuron: the role of glial cells in amyotrophic lateral scl...

ABSTRACT Motor neuron disease is one of the major groups of neurodegenerative diseases, mainly represented by amyotrophic lateral sclerosis. Despite wide genetic and biochemical data regarding its pathophysiological mechanisms, motor neuron disease develops under a complex network of mechanisms not restricted to the unique functions of the alpha motor neurons but which actually involve diverse functions of glia...

C9orf72-related disorders: expanding the clinical and genetic spectrum of neuro...

Neurodegenerative diseases represent a heterogeneous group of neurological conditions primarily involving dementia, motor neuron disease and movement disorders. They are mostly related to different pathophysiological processes, notably in family forms in which the clinical and genetic heterogeneity are lush. In the last decade, much knowledge has been acumulated about the genetics of neurodegenerative diseases,...

Non-progressive cerebellar ataxia and previous undetermined acute cerebellar in...

Cerebellar ataxias represent a wide group of neurological diseases secondary to dysfunctions of cerebellum or its associated pathways, rarely coursing with acute-onset acquired etiologies and chronic non-progressive presentation. We evaluated patients with acquired non-progressive cerebellar ataxia that presented previous acute or subacute onset. Clinical and neuroimaging characterization of adult patients with...

Clinical and genetic basis of familial amyotrophic lateral sclerosis

Amyotrophic lateral sclerosis represents the most common neurodegenerative disease leading to upper and lower motor neuron compromise. Although the vast majority of cases are sporadic, substantial gain has been observed in the knowledge of the genetic forms of the disease, especially of familial forms. There is a direct correlation between the profile of the mutated genes in sporadic and familial forms, highlig...
