Due to the progressive aging of the society, the prevalence and socioeconomic burden of neurodegenerative diseases are predicted to rise. The most common neurodegenerative disorders nowadays, such as Parkinson's disease, Alzheimer's disease, and amyotrophic lateral sclerosis, can be classified as proteinopathies. They can be either synucleinopathies, amyloidopathies, tauopathies, or TDP-43-related proteinopathies; thus, nanoparticles with a potential ability to inhibit pathological protein aggregation and/or degrade already existing aggregates can be a promising approach in the treatment of neurodegenerative diseases. As it turns out, nanoparticles can be a double-edged sword; they can either promote or inhibit protein aggregation, depending on coating, shape, size, surface charge, and concentration. In this review, we aim to emphasize the need of a breakthrough in the treatment of neurodegenerative disorders and draw attention to nanomaterials, as they can also serve as a diagnostic tool for protein aggregates or can be used in a high-throughput screening for novel antiaggregative compounds.

The present report documents a patient harboring an alpha-synuclein p.A53T variant from a family presenting with autosomal dominant inheritance, including four patients clinically diagnosed with Parkinson's disease (PD) and two with dementia. The alpha-synuclein p.A53T variant is linked to young- or middle-aged onset parkinsonism and cognitive decline. Our patient had a different haplotype from that of a patient with a p.A53T variant from an Italian family. The proband presented at 42 years of age with progressive parkinsonism and good response to levodopa in the early stages of the disease. At 46 years of age, he developed delusions and cognitive decline. Brain magnetic resonance imaging showed bilateral atrophic changes in the hippocampus and temporal lobes. He died of pneumonia at the age of 52 years. Neuropathological examination revealed severe neuronal loss in the substantia nigra, locus coeruleus, and dorsal nucleus of the vagus nerve, as well as widespread Lewy pathology including Lewy bodies and neurites, corresponding to Braak stage 6, and diffuse neocortical-type PD. There was mild appearance of tau pathology and glial cytoplasmic inclusion, in the absence of TDP-43 pathology. Alpha-synuclein p.A53T characteristically cause the Lewy body pathology and the symptoms, that resembled those of the reported patients with p.A53T.
