The authors report two cases of amyotrophic lateral sclerosis (ALS) misdiagnosis (a craniocervical junction disorder, and a cervical spinal cord ependymoma). They review some causes of ALS-like syndrome and propose a protocol to be adopted for the study of all patients who present clinical abnormalities suggesting ALS.

Motor neuron diseases, such as amyotrophic lateral sclerosis (ALS) and progressive bulbar palsy, involve loss of muscle control resulting from death of motor neurons. Although the exact pathogenesis of these syndromes remains elusive, many are caused by genetically inherited mutations. Thus, it is valuable to identify additional genes that can impact motor neuron survival and function.

The blood-brain barrier (BBB) is a highly selective, semipermeable barrier critical for maintaining brain homeostasis. The BBB regulates the transport of essential nutrients, hormones, and signaling molecules between the bloodstream and the central nervous system (CNS), while simultaneously protecting the brain from potentially harmful substances and pathogens. This selective permeability ensures that the brain is nourished and shielded from toxins.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative malady that causes progressive degeneration and loss of motor neuron function in the brain and spinal cord, eventually resulting in muscular atrophy, paralysis, and death. Neural stem/progenitor cell (NSPC) transplantation can improve bodily function in animals and delay disease progression in patients with ALS. This paper summarizes and analyzes the efficacy and safety of neural stem/progenitor cell (NSPC) transplantation as a treatment for ALS, aiming to improve function and delay disease progression in patients.

Objective: Tofersen, an antisense oligonucleotide, has recently received FDA and EMA approval for treating amyotrophic lateral sclerosis (ALS) in adults with SOD1 gene mutations. This systematic review and meta-analysis synthesized evidence on tofersen's safety and efficacy in patients with SOD1-related ALS.

Healthy brain functioning requires a continuous fine-tuning of gene expression, involving changes in the epigenetic landscape and 3D chromatin organization. Alzheimer's disease (AD), amyotrophic lateral sclerosis (ALS), and frontotemporal dementia (FTD) are three multifactorial neurodegenerative diseases (NDDs) that are partially explained by genetics (gene mutations and genetic risk factors) and influenced by non-genetic factors (i.e.
