Abstract

This book compiles all articles within the Research Topic "Neuropsychology and neuropsychiatry of neurodegenerative disorders" published in the journal Frontiers in Aging Neuroscience. The call was launched in 2014 and closed in 2015 with 21 articles published. Papers deal on several important topics of neuropsychology -such as language and visuospatial functions- and neuropsychiatry - such us the emotional or motivational spheres - , and the interphase between them. There are also articles on psychometry, brain morphometry, brain connectivity, diagnostic tests and interventional studies. All these articles are focused on neurodegenerative conditions, mostly Alzheimer’s disease and Parkinson’s disease. Interestingly, several articles addressed the early stages of these diseases. All together, this Research Topic provides a rich perspective of the research made today around neuropsychological and neuropsychiatric aspects of neurodegenerative diseases. We hope readers enjoy this collection of articles.

Abstract

The Golgi apparatus is a central organelle that lies at the heart of the secretory pathway. It ensures post-translational protein modifications such as glycosylation and cleavage as well as protein sorting to neuronal axons and dendrites. Structural and functional alterations of the Golgi apparatus (fragmentation and atrophy), which are collectively termed Golgi pathology, are now recognized as a constant feature of many neuro-degenerative diseases. However, the molecular mechanisms underlying these changes and their precise relevance to neurodegeneration have not yet been completely elucidated. This eBook contains 13 reviews that address the molecular mechanisms of Golgi pathology in Parkinson and Alzheimer diseases, amyotrophic lateral sclerosis (ALS) and spinal muscular atrophies, and discuss their potential relevance to the pathological loss of neuronal cell bodies, axons and synapses.

Abstract

The past decade has witnessed an explosion of knowledge regarding how mitochondrial dysfunction may translate into ageing and disease phenotypes, as well as how it is modulated by genetic and lifestyle factors. Impairment of the mitochondria may be caused by mutations or deletions in nuclear or mitochondrial DNA. Hallmarks of mitochondrial dysfunction include decreased ATP production, decreased mitochondrial membrane potential, swollen mitochondria, damaged cristae, increased oxidative stress, and decreased mitochondrial DNA copy number. In addition to energy production, mitochondria play an important role in regulating apoptosis, buffering calcium release, retrograde signaling to the nuclear genome, producing reactive oxygen species (ROS), participating in steroid synthesis, signaling to the immune system, as well as controlling the cell cycle and cell growth. Dysfunctional mitochondria have been implicated in ageing and in several diseases, many of which are age-related, including mitochondrial diseases, cancers, metabolic diseases and diabetes, inflammatory conditions, neuropathy, and neurodegenerative diseases such as Alzheimer’s, Parkinson’s, and Huntington’s disease. Additionally, a possible link between mitochondrial metabolism and the ubiquitin-proteasome and autophagy-lysosome systems is emerging as a novel factor contributing to the progression of several human diseases. This special issue calls for original research, mini and full reviews, and perspectives that address the progress and current standing in the vast field of mitochondrial biology. These include, but are not limited to: ageingneurodegenerative diseasesmitochondrial diseasesmetabolic diseasesprotein homeostasiscell/retrograde signalingoxidative stresspaincancerimmune systemtherapies to counteract mitochondrial dysfunction
