Multiple Sclerosis (MS) is characterized by motor, cognitive, and neuropsychiatric symptoms, which can occur independently. While MS is traditionally considered an inflammatory disease of the white matter, degeneration of gray matter is increasingly recognized as an important contributor to the progressive cognitive decline. A protective factor against the progression of cognitive dysfunction in MS could be the cognitive reserve, defined as resistance to brain dysfunction. Aim of the present study is to evaluate the role of cognitive reserve for different aspects of cognitive dysfunction of patients with MS. We found that patients with MS and lower cognitive reserve have poorer neuropsychological performance and slower information speed processing. These findings support the notion that intellectual reserve may protect some aspects of cognitive function in patients with MS.

Obstructive sleep apnea (OSA) is a pervasive disorder characterized by recurrent airway obstructions during sleep. OSA carries serious health risks, such as cardiovascular and cognitive impairments, and imposes a significant economic burden. This chapter provides a comprehensive overview of various biosensors currently employed for OSA detection, including in-lab polysomnography and flow-based home sleep apnea testing.

The concept of the central nervous system (CNS) reserve emerged from the mismatch often observed between the extent of brain pathology and its clinical manifestations. The cognitive reserve reflects an "active" capacity, driven by the plasticity of CNS cellular components and shaped by experience, learning, and memory processes that increase resilience. We propose that neuroglial cells are central to defining this resilience and cognitive reserve.

Alzheimer's disease (AD) is a major neurodegenerative disorder influenced by both genetic and environmental factors. Mentally stimulating activities are believed to reduce cognitive decline by establishing a cognitive reserve, although the underlying neurobiological mechanisms remain elusive. In this study, we investigate the role of parvalbumin-expressing inhibitory neurons (PV+) and their perineuronal nets (PNN) in the establishment of cognitive reserve using a mouse model of AD.

Intracranial calcifications (ICCs) are a characteristic neuropathological feature of several congenital viral infections, including Zika virus (ZIKV), cytomegalovirus (CMV), and lymphocytic choriomeningitis virus (LCMV). These lesions are linked to severe neurodevelopmental outcomes, such as microcephaly, epilepsy, and cognitive deficits, yet the mechanisms underlying their formation and resolution remain unclear. ICCs are thought to arise from an imbalance in osteogenic and osteolytic signaling in the developing brain.

Background: Cognitive reserve (CR) refers to the discrepancy between brain pathology and observed cognitive decline. While education is a key indicator of CR, its role as a potential moderator in the relationships between brain morphology and cognitive impairments in Parkinson's disease (PD) remains unclear. This study examined whether education affects the relationship between brain age and cognitive impairments in patients with PD.
