It is therefore important to recognize dementia at an early stage and identify possible predictors. The existing methods, like different parameters of ß-Amyloid and Tau quantification in cerebrospinal fluid (CSF) or the living brain by measure of PET, are invasive and expensive. Therefore, the present study investigates the predictive value of a battery of clinical, neuropsychological, and blood parameters as well as two neurophysiological methods (functional near-infrared spectroscopy [fNIRS] and vagus somatosensory evoked potentials [VSEP]) which are easy to perform, less invasive and cost-efficient, for developing cognitive impairments in the elderly.In this longitudinal, prospective study, we enrolled 604 healthy participants between 70 and 77 years of age. The participants were invited back after a mean time interval of 3 years and 11 months, and after 7 years and 8 months, and their cognitive impairments were determined.Here we show that the development of cognitive impairments after approximately 8 years can be predicted not only by previously known risk factors such as ApoE4 risk alleles, dysosmia, or poor cognitive performance at baseline but that latency prolongation in the VSEP and altered functional activation patterns measured by NIRS at baseline also provide additional predictive value.We therefore suggest that both neurophysiological parameters, VSEP and NIRS, should be included in future studies, investigating the prediction of dementia.

Although primarily characterized by motor degeneration, cognitive dysfunction is an important non-motor symptom that has a negative impact on patient and caregiver burden. Mild cognitive deficits are present in a subgroup of non-demented patients with ALS, often preceding motor symptoms. Detailed neuropsychological assessments reveal deficits in a variety of cognitive domains, including those of verbal fluency and retrieval, language, executive function, attention and verbal memory. Mild cognitive impairment (MCI), a risk factor for developing dementia, affects between 10% and over 50% of ALS patients. Neuroimaging revealed atrophy of frontal and temporal cortices, disordered white matter Integrity, volume reduction in amygdala and thalamus, hypometabolism in the frontal and superior temporal gyrus and anterior insula. Neuronal loss in non-motor brain areas, associated with TDP-43 deposition, one of the morphological hallmarks of ALS, is linked to functional disruption of frontostriatal and frontotemporo-limbic connectivities as markers for cognitive deficits in ALS, the pathogenesis of which is still poorly understood. Early diagnosis by increased cerebrospinal fluid or serum levels of neurofilament light/heavy chain or glial fibrillary acidic protein awaits confirmation for MCI in ALS.

Monoamine oxidase is classified into type A and B (MAO-A, MAO-B) according to the substrate specificity and sensitivity to inhibitors. The isoenzymes are different proteins coded by different genes localized on the X-chromosome, but they have identical intron-exon organization, similar protein structure and enzymatic mechanism and are considered to be derived from the same ancestral gene. The isoform-specific transcription organization regulates expression and function of MAO-A in response to cellular signaling pathways and environmental factors. MAO-A shows distinct properties and functions: isoform-specified polymorphisms, localization in catecholamine neurons, expression during early embryonic stage, regulation of brain architecture development and mediation of death and survival of neuronal cells. MAO-A is more flexible to genetic and environmental changes than MAO-B. Defective MAO-A expression impairs embryonic brain development and causes adult abnormal mood and behavior, as shown by human male cases with MAO-A deletion. This paper presents the regulation of brain MAO-A expression epigenetically by interaction between genetic and environmental factors. Association of aberrant MAO-A expression and activity with aggression, asocial behaviors, depressive disorders, and neurodegenerative diseases is discussed.
